A sickness at the heart of Europe

Drug policy public hearing – a revivalist meet for the disciples of dope.

A Brussels Parliament sketch by Peter Stoker – Director, National Drug Prevention Alliance

_____________________________________________________________

In the comfortable and prestigious surroundings of the European Parliament, a ‘Public Hearing’ was – in the event – heard by very few of The Public. Perhaps this is just as well, for the average citizen might have torched this expensive building, built from his tax money, had they heard what was being said.

Under the name of the Civil Liberties,  Justice and Home Affairs Committee, the hearing concerned what was euphemistically called the ‘Anti-Drug’ Strategy, 2005 – 2012, and its attendant ‘Action Plans’ (2005 – 2008 and 2009 – 2011). Enthusiasts of drug policy will know the special significance of 2008; this is the year in which the UN is set to review its Conventions on Drugs, for which more than 100 nations have signed up, thereby generating an enormous and positive influence on drug policy around the world. It is precisely because the Conventions have a positive influence, a bulwark against legalisation, that they are hated by the pro-legalisation crowd. They would kill them today if they could but meanwhile they are working behind and in front of every available screen to administer a death blow as soon as they can.

Deep concern for the public health, social cohesion and safety of European society was cited as the drive for the ‘Anti-Drug’ Strategy – surely matters of interest to The Public, but this meeting was populated by a rather different variety of human being.

Instead of the public there was a collection of around 150 people – of which more than 100 came ‘on a mission from Gomorrah’, bearing banners and leaflets, and demanding a Europe of free drugs – not a Europe free of drugs. Largely in harmony with this aspiring cluster were some 15 MEPs who, if they spoke at all, spoke in terms which garnered the applause of the 100. Also on hand were around 25 EU officials who maintained at discreet silence – in all but one noteworthy case. Mathematicians amongst you will note that this leaves about five people are not accounted for? Who they? The prevention platoon – including yours truly.

Known drug legalisers and liberalisers were greeted like old friends – which maybe they were – and were given reserved seating plus arranged speaking slots in the agenda. Thus were we treated to presentations by ENCOD, TNI, IAPL and others who would not be given house room in any self-respecting house.

Looking on benevolently but keeping a low profile was Mike Trace, the disgraced former Deputy Drugs Tsar for the UK who, on the eve of his elevation to head of Demand Reduction for the UN, was spectacularly exposed by the London Daily Mail as running covert operations with legaliser bodies, notably those bankrolled by George Soros. Trace was obliged to resign his seat at the UN even before he had begun warming it, but he remains a force on the UK and European scene, the beneficiary of a determined rehabilitation scheme by those who feel there is still some useful mileage in him. He is a top cat in Drug Treatment Limited, in the Beckley Foundation, and in RAPt – the Rehabilitation of Addicted Prisoners Trust – the breadwinner job he has held since before his heady days of Drug Tsardom.

The meeting was chaired by Belgian MEP Antoine Duquesne, and did little to diminish his reputation as a strange person. A welcome was offered by the Health Minister for Luxemburg, who promised that of all present today had left their dogmas leashed up outside the front door, and that no preachers had been admitted. Our main goal, he suggested, should be free to reduce Harm … not only the physiological harm drug-users suffer but also the harm of their social exclusion (presumably users should be set on a pedestal in society). The minister concluded by entreating all present to not stick to a static view; there are many approaches, he said, witness the contents of the Action Plan produced by the splendidly named Horizontal Drug Group on the 23rd of February this year.

Next up was a spokesman for the Pompidou Group, Bob Kaiser, who did his best to maintain gravitas in presenting a predictable and unimaginative series of recommendations, ending with the plea that money should not be spent on new organisations (the implication being that it was better to spend it on old organisations – like his).

Paul Griffiths, spokesman for the Lisbon-based monitoring centre, EMCDDA,  uttered the recurrent plea for more and better data, not withstanding what he saw as improvements in recent years. We needed, he said, to get much better at collecting evidence, if – that is – evidence-based policy (as distinct from policy-based evidence) is the goal.

A sanguine spokesman from the International Red Cross made new friends in the audience when he asserted that the notion of a drug-free world is unrealistic and that it was in the nature of man to swallow psychoactive substances – much in the way he had evidently swallowed this rhetoric. He lost one friend, however, when he dismissed the concerns of of Madame Roure, MEP for Lyon, France, who spoke of young children in deprived areas being drawn into drug use; that – said the Red Cross man – was a South American or Eastern Europe problem i.e. nothing for us civilised types over here to get excited about. Madame R gave him a short shrift; she was, she said, talking about the fair city of Lyon – not Bogota or Bucharest.

Luc Beauman, spokesman for ENCOD, knew he was preaching to the converted. From his position on the top table he presented a relaxed and intellectually stylish restatement of their position. At this, the 100 erupted into thunderous and extended applause, holding aloft colourful if modestly-sized banners (possibly designed to fit comfortably inside one’s jacket).

It was then that the assembled drug freedom fighters in the cheap seats became restless. Surely, the first cautiously suggested, it is the system of making drugs illegal which just makes prevention harder to appear: wouldn’t a bright new day dawn and everything be super if we just legalised them all?. Others quickly followed over this rickety bridge head: A man from Bologna complained that he couldn’t get a drink after 9pm or smoke cigarettes in shops – this is Prohibitionism even with legal drugs, so it’s just part of the same problem, and we must recognise that prohibitionists are dangerous animals. The appropriately-named ‘Freek’ Polack claimed that he had just one question for the Parliament – then proceeded to ask five; the gist of it was that policies which don’t enable drug use are failures, so why are we silent on this failure? He was received in silence.

An impassioned plea from a hirsute young German drug user took the form of a velvet trap – “You say we need your help, I say you need our help, so when will you stop isolating and demonising us?” (as in ‘When did you stop beating your wife?’).

An Italian plaintiff said he knew of five people, arrested for drug possession who, when their names were published in the media, committed suicide.The notion of an early death during this meeting was perhaps growing in the minds of some, who were by now finding the whole affair life-threatening.

In the name of balance, a Belgian prevention centre worker was invited to speak. He remarked that the discussions “seemed to getting very polemical” – perhaps unintentionally implying that they had not been polemical from the kick-off.

ENCOD’s Luc Beauman took another bite at the cherry; if cannabis is demonised, he opined, then kids don’t take any drug information seriously. Ergo, unreliable prevention messages damage all prevention messages, so his argument went.

 ( Unreliable libertarian messages did not, it seemed, qualify for the same criticism). ‘Regulation’ – the new buzzword for Legalisation – would usher in a new dawn of ‘ sincere and and honest information’. This would be best achieved by involving citizens, a pious hope of politicians since the 1980s but sadly a hope yet to be realised. 2008 or 2012 were, said Luc, intolerably far away … “What do we want? Regulation! When do we want it? Now!” … and so on …

It was left to the one civil servant who did speak to administer a cold douche of reality. Carel Edwards, Head of the Anti-Drugs Coordination Unit at the EC, told it how it was – and is likely to remain. He was given just six minutes to speak; and said “If you think I can, or will state that the EC position in six minutes, think again”. If today had demonstrated anything, he said, it had demonstrated once again the enormous confusion over the whole subject. The notion that opinions from street level would reach to and direct the top of government is the kind of dream that only comes from those smoking unusual tobaccos. In support of this he cited how few MEPs were here today – and the fact that no of single member state has yet reached what can be called a consenus on drug policy.

He made a somewhat bizarre reference to the Institute for Global Drug Policy Conference held in the European Parliament building about a month ago, characterising this as “Americans expressing a very repressive policy” (It seems that an attendance register, showing the wide variety of European and worldwide delegates at that meeting might helpfully enlighten him). In closing, he said the EC’s aim was to produce an ‘ideology-free, evidence-based’ policy. Those who wanted to debate ideology should go elsewhere; coming as it did after three and a half hours of almost unceasing ideology-pushing, this remark fell on stoned and stony ground alike.

A new compound similar to the active component of marijuana (cannabis) might provide effective pain relief without the mental and physical side effects of cannabis, according to a study in the July issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

The synthetic cannabinoid (cannabis-related) compound, called MDA19, seems to avoid side effects by acting mainly on one specific subtype of the cannabinoid receptor. “MDA19 has the potential for alleviating neuropathic pain without producing adverse effects in the central nervous system,” according to the study by Dr Mohamed Naguib of The University of Texas M.D. Anderson Cancer Center.

MDA19 Works on a Single Cannabinoid Receptor
The researchers performed a series of experiments to analyze the pharmacology and effects of the synthetic cannabinoid MDA19. There are two subtypes of the cannabinoid chemical receptor: CB1, found mainly in the brain; and CB2, found mainly in the peripheral immune system.

Dr. Naguib’s group has been doing research to see if the cannabinoid receptors—particularly CB2—can be a useful target for new drugs to treat neuropathic pain. Neuropathic pain is a difficult-to-treat type of pain caused by nerve damage, common in patients with trauma, diabetes, and other conditions.

MDA19 was designed to have a much stronger effect on the CB2 receptor than on the CB1 receptor. In humans, MDA19 showed four times greater activity on the CB2 receptor than on the CB1 receptor. In rats, the difference was even greater. The experiments also showed that MDA19 had “protean” effects, so-called after the shape-shifting Greek sea god Proteus—under different conditions, it could either block or activate the cannabinoid receptors.

In rats, treatment with MDA19 effectively reduced specific types of neuropathic pain, with greater effects at higher doses. At the same time, it did not seem to cause any of the behavioral effects associated with marijuana.

Potential to Develop Effective Pain Drugs that Avoid Side Effects
The “functional selectivity” of MDA19—the fact that it acts mainly on the CB2 receptor and has a range of effects under differing conditions—could have important implications for drug development. “[W]ith functionally selective drugs, it would be possible to separate the desired from the undesired effects of a single molecule through a single receptor,” Dr. Naguib and colleagues write.
This means that MDA19 could be a promising step toward developing medications that have the pain-reducing effect of cannabinoids while avoiding the mental and physical side effects of marijuana itself. However, more research will be needed before MDA19 or other agents that act on the CB2 receptor are ready for testing in humans.

“These elegant studies by Professor Naguib demonstrate remarkable analgesic properties for this synthetic cannabinoid,” comments Dr. Steven L. Shafer of Columbia University, Editor-in-Chief of Anesthesia &Analgesia. “The studies suggest a novel mechanism for this protean agonist. Although preliminary, these studies suggest that synthetic cannabinoids may be significant step forward for patients suffering from neuropathic pain.”

A typical drug user’s transition to addiction could result from a persistent impairment of synaptic plasticity in a key structure of the brain, suggests a new French study.
The research, by the teams of Pier Vincenzo Piazza and Olivier Manzoni, at the Neurocentre Magendie in Bordeaux, appears in the journal Science.

This study is the first demonstration that a correlation exists between synaptic plasticity and the transition to addiction. The results from the teams at Neurocentre Magendie call into question the hitherto held idea that addiction results from pathological cerebral modifications, which develop gradually with drug usage.

Their results show that addiction may, instead, come from a form of anaplasticity, i.e. from incapacity of addicted individuals to counteract the pathological modifications caused by the drug to all users.

The voluntary consumption of drugs is a behaviour found in many species of animals. However, it had long been considered that addiction, defined as compulsive and pathological drug consumption, is behaviour specific to the human species and its social structure.

In 2004, the team of Pier Vincenzo Piazza showed that the behaviours which define addiction in humans, also appear in some rats which will self administer cocaine. Addiction exhibits astonishing similarities in men and rodents, in particular the fact that only a small number of consumers (humans or rodents) develop a drug addiction. The study of drug dependent behaviour in this mammal model thus opened the way to the study of the biology of addiction.

Today, thanks to a fruitful collaboration, the teams of Pier Vincenzo Piazza and Olivier Manzoni are reporting discovery of the first known biological mechanisms for the transition from regular but controlled drug taking to a genuine addiction to cocaine, characterised by a loss of control over drug consumption.

Chronic exposure to drugs causes many modifications to the physiology of the brain. And researchers wanted to find out which of these modifications is responsible for the development of an addiction.
The addiction model developed in Bordeaux provides a unique tool to answer this question. Thus it allows comparing animals who took identical quantities of drugs, but of which only few become addicted.

By comparing addict and non-addict animals at various time points during their history of drug taking, the teams of Pier Vincenzo Piazza and Olivier Manzoni have demonstrated that the animals which developed an addiction to cocaine exhibit a permanent loss of the capacity to produce a form of plasticity known as long-term depression (or LTD).

LTD refers to the ability of the synapses (the region of communication between neurons) to reduce their activity under the effect of certain stimulations. It plays a major role in the ability to develop new memory traces and, consequently, to demonstrate flexible behaviour.

After short-term usage of cocaine, LTD is not modified. However, after a longer use, a significant LTD deficit appears in all users. Without this form of plasticity, which allows new learning to occur, behaviour with regard to the drug becomes more and more rigid, opening the door to development of a compulsive consumption.

The brain of the majority of users is able to produce the biological adaptations which allow to counteract the effects of the drug and to recover a normal LTD.
By contrast, the anaplasticity (or lack of plasticity) exhibited by the addicts leaves them without defences and hence the LTD deficit provoked by the drug becomes chronic.

This permanent absence of synaptic plasticity would explain why drug seeking behaviour becomes resistant to environmental constraints (difficulty in procuring the substance, adverse consequences of taking the drug on health, social life, etc.) and consequently more and more compulsive. Gradually, control of the taking of the drug is lost and addiction appears.

For Pier-Vincenzo Piazza and his collaborators, these discoveries also have important implications for developing new treatment of addiction.

“We are probably not going to find new therapies by trying to understand the modifications caused by a drug in the brains of drug addicts,” explain the researchers, “since their brain is anaplastic.” For the authors, “The results of this work show that it is in the brain of the non-addicted users that we will probably find the key to a true addiction therapy.

Indeed,” the authors estimate, “understanding the biological mechanisms which enable adaptation to the drug and which help the user to maintain a controlled consumption could provide us with the tools to combat the anaplastic state that leads to addiction”. (ANI)

Researchers have found that a specific and remarkably small fragment of RNA appears to protect rats against cocaine addiction – and may also protect humans.
The discovery could lead to better ways of predicting drug abuse risk and treating addictions

In the study, researchers at The Scripps Research Institute in Jupiter, Florida found that cocaine consumption increased levels of a specific microRNA sequence in the brains of rats, named microRNA-212.

As its levels increased, the rats exhibited a growing dislike for cocaine, ultimately controlling how much they consumed.
On the other hand, as levels of microRNA-212 decreased, the rats consumed more cocaine and became the rat equivalent of compulsive users.

The study’s findings suggest that microRNA-212 plays a pivotal role in regulating cocaine intake in rats and perhaps in vulnerability to addiction.
Interestingly, the same microRNA-212 identified in this study, is also expressed in the human’s dorsal striatum, a brain region that has been linked to drug abuse and habit formation.

“This study enhances our understanding of how brain mechanisms, at their most fundamental levels, may contribute to cocaine addiction vulnerability or resistance to it,” Nature quoted National Institute on Drug Abuse (NIDA) Director Dr. Nora D. Volkow, as saying.

“This research provides a wonderful example of how basic science discoveries are critical to the development of new medical treatments and targeted prevention,” he added.

Rats with a history of extended cocaine access can demonstrate behavior similar to that observed in humans who are dependent on the drug.
Current data show that about 15 percent of people who use cocaine become addicted to it.
The findings suggest that microRNAs may be important factors
contributing to this vulnerability.

“The results of this study offer promise for the development of a totally new class of anti-addiction medications. Because we are beginning to map out how this specific microRNA works, we may be able to develop new compounds to manipulate the levels of microRNA-212 therapeutically with exquisite specificity, opening the possibility of new treatments for drug addiction,” said Paul J. Kenny, senior author on the study.
The study is published in the journal Nature. (ANI)

Marijuana used for medical purposes has the same long term effect on the user as marijuana used for recreation. Marijuana use can cause impairment of short-term memory, attention, motor skills, reaction time, and the organization and integration of complex information.

Marijuana use alters perceptions and creates time distortion and can cause drowsiness and lethargy. Heavy marijuana use can cause apathy, decreased motivation, and impair cognitive performance and can cause mental health problems.

Employees who use marijuana off-duty are still effected by it. Impaired cognition that can cause lapses in judgement can remain for a long period. Memory defects can last as long as six weeks. See: Abbie Crites-Leoni, Medicinal Use of Marijuana: Is the Debate a Smoke Screen for Movement Toward Legalization? 19 J. Legal Med. 273, 280 (1998) (citing Schwartz, et al., Short- Term Memory Impairment in Cannabis-Dependent Adolescents, 143 Am. J. Dis. Child. 1214 (1989)

Employers may be liable for the actions of employee who use marijuana especially those employees in safety sensitive positions. The more chronic the use of “medical” marijuana the higher the risk.

VIOLATIONS OF FEDERAL LAW

Will employers have to accommodate marijuana use that violates federal law? Marijuana, remains illegal under federal law because of its “high potential for abuse,” its lack of any “currently accepted medical use in treatment in the United States,” and its “lack of accepted safety for use … under medical supervision.”Gonzales v. Raich, 545 U.S. 1 (2005); United States v. Oakland Cannabis Buyers’ Cooperative, 532 U.S. 483 (2001)

IF THIS BILL PASSES “MEDICAL” MARIJUANA WILL RESULT IN MORE MARIJUANA USE AMONG EMPLOYEES

As consumers we all pay for lost productivity and job-related accidents in the final costs of the produced goods and higher insurance premiums due to workplace accidents. Drug using employees are not as safe. They are 3.6 times more likely to be involved in a work-related accident than their non-using employee, and 5 times more likely to file workers’ compensation claims. As many as 50% of all workers’ compensation claims may involve substance abuse.[FN1]

The U.S. Postal Service did a study that showed that substance abusers have 55% more accidents, experience 85% more on-the-job injuries, and have a 78% higher rate of absenteeism when compared to non-substance abusing employees.[FN2] A report by the National Safety Council claimed that 80% of those injured in serious drug-related work accidents are not the drug using employees, but innocent employees and others.[FN3]

Drug using employees commit workplace crimes. There is a very significant statistical correlation between drug use and criminal conduct.[FN4]

Substance abuse also causes:
Domestic and financial difficulties for employees;
Poor judgment in employment decision making;
Potential embarrassment to the employer as a result of off-duty conduct, which may be publicized, including criminal charges, diversion of supervisory and managerial time;
Damage to company property; and
Time devoted to discipline and grievance matters.[FN5]

While the studies vary somewhat, it is clear that there is substantial substance abuse in the workplace and it has a powerful negative impact on our economy and productivity. The increased use of “medical” marijuana will magnify all these problems.

A new study from the David Geffen School of Medicine at UCLA suggests that increasing cigarette taxes could be an effective way to reduce smoking among individuals with alcohol, drug or mental disorders.

The study, published online in the American Journal of Public Health, found that a 10 percent increase in cigarette pricing resulted in an 18.2 percent decline in smoking among people in these groups.

The findings demonstrate that increasing cigarette taxes could be a way to curb smoking, which is still the leading preventable cause of death in the United States, according to the study’s lead author, Dr. Michael Ong, an assistant professor of medicine in the division of general internal medicine and health services research at the Geffen School of Medicine.
“Whatever we can do to reduce smoking is critical to the health of the U.S.,” said Ong, who is also a researcher at UCLA’s Jonsson Cancer Center. “Cigarette taxes are used as a key policy instrument to get people to quit smoking, so understanding whether people will really quit is important.

Individuals with alcohol, drug or mental disorders comprise 40 percent of remaining smokers, and there is little literature on how to help these people quit smoking.”

Prior research on the effect of cigarette pricing on smoking, which had been conducted using information from 1991, suggested that individuals with mental illness were less likely than other individuals to quit due to price increases. Unlike that research, however, the current study expanded the research to include people with alcohol and drug disorders.

The researchers based their work on data from 7,530 individuals from the 2000-01 Healthcare for Communities Household Survey. Of those, 2,106 people, or 23 percent, had alcohol, drug or mental disorders during the previous year. Of that group, 43.8 percent were smokers — a much higher proportion than among rest of the population.

Though the researchers found that people with alcohol dependence did not cut down on cigarettes when prices rose, people with binge-drinking problems, substance-use disorders and mental disorders were significantly more likely to quit smoking if prices rose, as would occur with a cigarette tax increase.

While the study does suggest that increasing cigarette prices through taxation could reduce smoking among individuals with alcohol, drug or mental disorders, the authors note that further study is needed to determine if recent cigarette price increases have reduced smoking among individuals with such disorders, and whether the identified association is causal.

Neuropharmacologists ran clinical trials to find that a drug called topiramate is an effective therapeutic medication for decreasing heavy drinking and diminishing the physical and psychosocial harm caused by alcohol dependence.

The drug works by blocking the right amount of the feel good effects of alcohol (brought on by increased levels of dopamine), making drinking less enjoyable and thus reducing cravings and helping to stop heavy drinking.

Topiramate was also found to lower blood pressure and cholesterol levels which may lead to a decrease in heart disease in alcohol dependent patients.

Alcoholism affects over 17 million people. Without proper treatment, it’s a devastating disease that can ruin lives and relationships. A new therapy that comes in a pill is bringing new hope to alcoholics.

There was a time in Christine Flemming’s life when alcohol came before her kids.
“I can’t remember when my daughter was very little, because I was drinking so much,” said Flemming. “That affected me a lot.”

Flemming needed help, but traditional treatment methods didn’t work. Now she’s on a new kind of therapy in the form of a pill called topiramate. It has changed her life. “I can tell you that it cuts my cravings, and I don’t feel like I have to drink,” Flemming said. “I don’t feel like that’s something I need in my life and I have to do.”

Alcohol increases levels of dopamine, a chemical in the brain that makes us feel good. The drug works by blocking the right amount of the feel-good effects from alcohol to reduce cravings and help stop heavy drinking. During clinical trials, neuropharmacologists were surprised to learn it also lowers blood pressure and cholesterol levels, which may lead to a decrease in heart disease in alcohol dependent patients.

“Most of the morbidity due to alcoholism is caused by secondary effects of all these other systems, so to have a drug that begins to correct all those other physical abnormalities is extremely helpful,” said Bankhole Johnson, Ph.D., a Neuropharmacologist at the University of Virginia in Charlottesville, Va.

The drug helped improve Fleming’s health and end her dependence on alcohol. She cut her drinking from 15 beers a day to just three, so time with her kids is now a priority.
“It’s made a big difference,” Flemming said. “It’s made a really big difference, and I feel like I’m actually there for my family.”

Qualifying patients can find out how to receive the drug by contacting their primary care doctors.

WHAT IS TOPIRAMATE? Topiramate is a drug originally discovered in 1979. It is prescribed as an epilepsy medication and for migraine headaches. It is also used for a number of other purposes, including as a treatment for people with alcoholism.

Researchers believe that topiramate works in two ways. First, it reduces the release of dopamine that follows the consumption of alcohol. This reduces the positive feeling that people receive from alcohol, and thus reduce the incentive to drink. Second, topiramate interferes with the protein glutamate which normally excites dopamine neurons and again, lessening the ýfeel goodý effect of dopamine from alcohol.

WHAT IS ALCOHOL? Alcohol is created through the natural process of fermentation. This happens when yeast and sugar from vegetables and grains change the sugar into alcohol. When you drink alcohol, it is absorbed into your bloodstream, where it can affect the central nervous system, which is the control center for your entire body.

Alcohol slows down this control center with its sedative effect. In moderation it can reduce anxiety, but it also blocks some of the commands the brain sends to other parts of the body, so it alters your senses. That’s why, when drunk, people often have trouble walking, talking, and some may even “black out,” forgetting what they said or did. Drinking an excessive amount of alcohol can even be fatal.

California data on drivers involved in passenger vehicle fatal crashes using Marijuana were analyzed to determine the impact on traffic safety and to provide information on the possible impact of an initiative, the Tax and Regulate Cannabis Initiative or “TC2010” which is on the California ballot in November 2010 to reform and partially legalize Marijuana.

A total of 1240 persons were killed in the last five years in fatal motor vehicle crashes involving Marijuana. 230 were killed in 2008. Use has increase steadily in the last ten years and is now at 5.5% in fatal passenger vehicle crashes. The use in single vehicle fatal crashes where most drivers are tested shows an involvement rate of 8.3%.

The largest increases occurred in the 5 years following the establishment of the Medical Marijuana Program in January 2004. For the five years following legalization there were 1240 fatalities in fatal crashes, compared to the 631 fatalities for the five years prior, for an increase of almost 100%.

In 2008 there were 8 counties where more than 16% of the drivers in fatal crashes tested positive for Marijuana. Five of the 8 counties had rates over 20% Based on this experience, a use rate of 16% to 20% is very likely. A rate increase to only 16%, would result in 670
fatalities, and at 20% we would have about 840 fatalities annually. The 20% level would be more than triple the present level of 230 fatalities in 2008. At these levels, Marijuana would rival alcohol at 17.9%, as the top cause of traffic fatalities.

If “TC2010” passes, tax income on Marijuana is estimated at $1.4 billion annually compared to an estimated $4 billion or more economic loss from Marijuana related fatal crashes.
Over 80% of the Marijuana drivers are male, with a median age of 25. In addition, about half (48%) of the drivers using Marijuana also were legally intoxicated. About 75% of the drivers that used Marijuana did not use any other drug. About 1.2 fatalities were reported for each Marijuana involved driver.

“This report summarises the key findings from a report exploring public attitudes towards illegal drugs and drug misuse in Scotland, based on data from the 2009 Scottish Social Attitudes survey. It focuses in particular on attitudes towards opiate misuse, and on views of potential policy responses to this. However, it also places such attitudes in the context of wider views and experiences of illegal drugs.”

Main Findings
■ Support for legalising cannabis – which increased in Scotland (as in the rest of the UK) in the late 1990s – has fallen considerably in more recent years, from 37% in 2001 to 24% in 2009. Attitudes towards prosecution for possession of cannabis for personal use also hardened between 2001 and 2009.

■ Most people said taking cocaine occasionally is wrong – 76% rated it as 4 or 5 on a scale where 5 meant ‘very seriously wrong’.

■ 45% of people agreed that ‘Most people who end up addicted to heroin have only themselves to blame’, while just 27% disagreed.

■ Around half (53%) disagreed that ‘most heroin users come from difficult backgrounds’ (29% agreed).

■ Among those in paid employment, around half (47%) said they would be ‘very’ or ‘fairly comfortable’ working alongside someone they knew had used heroin in the past, while around 1 in 5 would be uncomfortable.

■ Just a quarter (26%) said they would be comfortable with someone who was receiving help to stop using heroin moving near to them, while half (49%) would be uncomfortable.

■ There was no public consensus on what should be the top government priority for tackling heroin use in Scotland – 32% chose ‘tougher penalties for those who take heroin’, 32% ‘more help for people who want to stop using heroin’ and 28% ‘more education about drugs’.

■ Just 16% agreed that people who possess heroin for personal use should not be prosecuted (compared with 34% for cannabis).

■ Public support for providing clean needles to injecting drug users fell from 62% in 2001 to 50% in 2009.

■ Opinion on educating young people about safer drug use was split – 44% agreed that young people should be given information about how to use drugs more safely, but 40% disagreed.

■ Four out of five (80%) agreed that ‘the only real way of helping drug addicts is to get them to stop using drugs altogether’. However, 29% agreed that ‘most heroin users can never stop using drugs completely’, while 27% said they neither agreed nor disagreed or did not know.

■ 63% disagreed that ‘Someone who has been a heroin addict can never make a good parent, even if their drug problems are in the past’.

■ Around two thirds (64%) said that young children of heroin users should be placed into temporary foster care until the parents stop taking heroin. A further 1 in 5 believed the child should stay at home while the family receives help from social workers and just 8% said the child should be permanently adopted by another family.

Levels of the serotonin transporter are low in the brains of users of ecstasy, according to a US National Institute of Drug Abuse-funded study by Toronto’s Centre for Addiction and Mental Health (CAMH) and The Hospital for Sick Children (SickKids) published today in the journal Brain.

Ecstasy (MDMA) is a stimulant drug widely used recreationally that is also being tested in clinical trials for the treatment of post-traumatic stress disorder.
Led by Dr. Stephen Kish at CAMH, this study provides confirmation of a previous finding from Johns Hopkins University that levels of the serotonin transporter (SERT) are low in cerebral cortex of chronic ecstasy users. The subjects were “typical” ecstasy users who used about two tablets of the drug twice a month.

SERT is a protein responsible for regulating levels of serotonin, a neurotransmitter important for mood and impulse control. Ecstasy interacts with SERT to cause the release of serotonin, an action that probably explains some of the behavioral effects of the drug such as increased sociability.

Scientists have long suspected that ecstasy might harm brain cells that use serotonin, but 12 years of brain scan studies have produced contradictory results, even within the same laboratory.
The CAMH study used a large subject size (49 drug users, 50 control subjects), confirmed by hair analysis that ecstasy users actually used the drug, and used an imaging probe that could measure SERT throughout the brain.
“We were surprised to discover that SERT was decreased only in the cerebral cortex and not throughout the brain, perhaps because serotonin nerves to the cortex are longer and more susceptible to changes. This finding is almost identical to newer data from Johns Hopkins and is the first time that one laboratory has actually been able to replicate results of another independent laboratory in a SERT study of ecstasy users.” said Dr. Kish.

Drug hair analysis indicated that many ecstasy users, probably unknowingly, also used methamphetamine, which might itself damage serotonin cells; however, low SERT was found both in ecstasy users who used and who did not use methamphetamine. Dr. Jason Lerch at SickKids showed that those ecstasy users who also used methamphetamine had a slightly thinner cerebral cortex.

Does low SERT equal “structural brain damage”? “Not necessarily” said co-author Dr. Isabelle Boileau of CAMH. “There is no way to prove whether low SERT is explained by physical loss of the entire serotonin nerve cell, or by a loss of SERT protein within an intact nerve cell.”
Dr. Kish suggests that low SERT might explain why many ecstasy users need to keep increasing the dose to experience the same effects, since SERT is necessary for the action of ecstasy. “Most of the ecstasy users of our study complained that the first dose is always the best, but then the effects begin to decline and higher doses are needed. The need for higher doses, possibly caused by low SERT, could well increase the risk of harm caused by this stimulant drug,” said Dr. Kish.

Combining a randomised trial with a ‘real-world’ test, studies of the Dutch Drinking Less programme have gone further than any others to establish the beneficial impacts of web-based alcohol self-help interventions.

The study was a ‘real-world’ test of a promising Dutch internet-based self-help intervention for problem drinking.
A previous randomised trial employing the methodological safeguards possible in tightly controlled research (particularly the recruitment of a comparison group not given access to the intervention) had established that the intervention reduced drinking. At issue in the featured study was whether similar drinking reductions would be seen when the intervention was made freely available to the general public. If they were, then the assumption could be made that these too were caused by having access to the intervention.

Drinking Less is an on-line, interactive programme with no personal therapist input. Aimed at risky drinkers among the general adult population, the intervention is based on principles derived from motivational interviewing, cognitive-behavioural therapies and self-control training. Its home page offers links to alcohol-related information, treatment services, a discussion forum, and the

Drinking Less self-help programme, the core of the intervention. Over a recommended six weeks (though this is entirely up to the user) the programme guides visitors in preparing to change their drinking, setting goals , implementing change, and finally sustaining it, preferably by drinking within recommended limits.

The earlier trial had found that six months later, at least 17% of adult problem drinkers randomly allocated to this intervention had reduced their drinking to within Dutch guidelines, compared to just 5% allocated to an on-line alcohol education brochure. Before the study, both groups had averaged about 55 UK units a week.

At follow-up, the Drinking Less group had cut consumption to about 36 UK units a week, but the brochure group had barely changed.

The featured study monitored what happened when over 10 months spanning 2007 and 2008 the web site was advertised to the Dutch public. During this time round 27,500 people visited the site, of whom 1625 signed up for the self-help programme, accessing it on average 23 times.

Typically they were well educated, employed, middle-aged men. On average they drank about 50 UK units a week, and nearly all who completed the on-line AUDIT screening questionnaire scored in a range indicative of alcohol abuse or dependence.
During the first seven of the 10 months, 378 of site visitors who signed up to the Drinking Less programme also agreed to participate in research to assess its impact. On average they drank roughly the same amount (95% exceeded Dutch guidelines) as all 1625 who signed up and were also similar in age, sex, employment, and motivation to change.

Despite some statistically significant differences, they were also broadly similar to participants in the earlier randomised trial. Over 8 in 10 had never received professional help for their drinking. A few weeks later a survey suggested that after signing up, nearly 9 in 10 went on to use the programme, though generally only a few times.
Of the 378 in the baseline sample, 153 responded to an on-line follow-up survey six months later. Before signing up to the programme, just 4% had confined their drinking within Dutch guidelines; six month later, 39% did so. They had also nearly halved their average consumption from 50 UK units to 27. On the ‘fail-safe’ assumption that the intervention had no impact on people who were not followed up, still the drinking reductions were statistically significant; from 5%, the proportion drinking within guidelines rose to 19%, and consumption fell from 51 UK units to 42.

Next the analysts compared these results with those from the six-month follow-up in the randomised trial. Based only on respondents to the follow-up surveys, and adjusting for differences between the samples, in the ‘real-world’ test over twice as many (unadjusted figures 36% v. 19%) people moved to drinking within Dutch guidelines. When the assumption was made that in both trials the intervention had no impact on people not followed up, the figures still favoured the ‘real-world’ test (15% v. 10%), but the difference was no longer statistically significant.

The researchers concluded that the featured study had shown that the benefits established by the randomised controlled trial would be sustained when the intervention was made routinely and generally available to the public. The expected throughput of 3000 Drinking Less programme users a year would amount to nearly 3% of the country’s problem drinkers who would otherwise not have received professional help. Probably because they require the drinker to take the initiative and visit the site, such interventions reach people who, compared to the totality of problem drinkers, are more likely to be women, employed, highly educated, and motivated to change their drinking. Given its low cost per user, this type of intervention seems to have a worthwhile place in a public health approach to reducing alcohol-related problems.

Though only a minority of site visitors may sign up for web-based alcohol programmes, nevertheless the numbers engaged can be very large, and the risk-reductions seem of the order typical in studies of brief advice to drinkers identified in health care settings. In these settings screening programmes typically identify people who are not actually seeking help for drinking problems – ‘pushing’ them towards intervention and change – while web sites ‘pull’ in people already curious or concerned about their drinking. As such these two gateways can play complementary roles in improving public health and offering change opportunities to people who would not present to alcohol treatment services. However, in Britain and elsewhere, both tactics reach only small fractions of the population who drinking excessively, leaving the bulk of the public health work to be done by interventions which drinkers generally cannot avoid and do not have seek out, such as price increases and availability restrictions.

With its combination of a randomised trial and a ‘real-world’ test, the featured research programme has gone further than any other in establishing the beneficial impacts of web-based alcohol interventions. However, largely because many site users do not complete research surveys, it remains impossible to be sure that the results seen in such studies will be replicated across the entire usership of the sites. Details below.

Strengths and limitations of the featured study
The featured study’s combination of a randomised trial with all its methodological safeguards, and a ‘real-world’ trial approximating normal conditions, affords what seems to be the best indication to date of the contribution web-based self-help interventions could make to reducing heavy drinking and associated health risks. However, its twin pillars are weakened by the fact that many people either did not join the studies or did not supply follow-up data; those who did may not have been typical of all the people who might access such sites.

In the randomised trial, 40% of the baseline sample did not complete the six-month follow-up survey, and in the featured study, nearly 60%. Though on the measures taken by the study the respondents generally seemed typical of the baseline sample, clearly something was sufficiently different to cause them to respond while the others did not. In both studies this problem was catered for by assuming that non-responders were also non-changers. Though this almost certainly underestimated the impact of the intervention, still in both there remained significant and worthwhile improvements.

What could not be catered for in either study was the degree to which people who join such studies differ from the much greater number who would use the web sites, but decline participation in research. This problem was especially apparent in the featured study, in which it seems that around 6% of site visitors signed up for the self-help programme. Of these, perhaps a third or slightly more of the people who signed up for the programme during the relevant period also agreed to participate in the research. In some important ways (including amount drunk and motivation to change) they seemed similar to the bulk of programme sign-ups, though the researchers suspect they were more likely to have engaged with the programme.

Opening more doors to change for more people
A review of computer-based alcohol services for the general public has rehearsed the advantages: immediate, convenient access for people (the majority in developed nations) connected to the internet; consequently able to capitalise on what may be fleeting resolve; anonymous services sidestep the embarrassment or stigma which might deter help-seeking; such services are available to people unwilling or less able to talk about their problems to a stranger; generally they are free and entail no travel costs or lost income due to time off work; very low operating cost per user if widely accessed; easily updated.

In consumption terms, the drinking problems of web site users are comparable to those of drinkers who seek treatment, yet few have received professional help, perhaps partly because their higher socioeconomic status and greater resources have enabled them to restrict the consequential damage. People who actually engage with web-based assessments of their drinking problems have more severe problems than those who just visit and leave. Including the randomised trial which paved the way for the featured study, the review found eight studies which evaluated the effectiveness of computer-based interventions for the general public.

In all but one the users significantly improved on at least one of the alcohol-related measures recorded by the studies.
A particular role for alcohol self-help sites may be to offer an easy, quick and accessible way to for drinkers to actualise their desire to tackle their problems, especially when that desire is allied with the resources to implement and sustain improvements without face-to-face or comprehensive assistance. After conducting the Project MATCH trial, some of the world’s leading alcohol treatment researchers argued that “access to treatment may be as important as the type of treatment available”. The implication is that in cultures which accept ‘treatment’ as a route to resolving unhealthy and/or undesirable drinking, having convincing-looking and accessible ‘treatment doors’ to go through may be more important than what lies behind those doors, as long as this fulfils the expectations of the client or patient. This is likely to be especially the case for people who retain a stake in conventional society in the form of marriages, jobs, families, and a reputation to lose. These populations – the kind the featured study suggests are attracted to self-help alcohol therapy web sites – have more of the ‘recovery capital’ resources needed to themselves do most of the work in curbing their drinking.

The British Down Your Drink site
The best known British alcohol self-help web site is the Down Your Drink site run by a team based at University College London, an initiative originally funded by the Alcohol Education and Research Council and now by the Medical Research Council’s National Prevention Research Initiative. In 2007 this was revised to offer set programmes from a one-hour brief intervention to several weeks, but also to generally give the user greater control over the use they made of the site. The approach remained based on principles and techniques derived from motivational interviewing and cognitive-behavioural therapies.

The previous version had been structured as six consecutive modules to be accessed weekly. An analysis of data provided by the first 10,000 people who registered at the site after piloting ended in September 2003 revealed that most were in their 30s and 40s, half were women, nearly two-thirds were married or living with a partner, just 4% were unemployed, and most reported occupations from higher socioeconomic strata.

As an earlier study commented, site users were predominantly middle class, middle aged, white and European. Six in 10 either did not start the programme, or completed just the first week. About 17% completed the six weeks. Of these, 57% returned an outcome questionnaire. Compared to their pre-programme status, on average they were now at substantially lower risk, and functioning better and living much improved lives.
The sample had been recruited over about 27 months, a registration rate of about 4500 a year. By way of comparison, in England during 2008/09, around 100,000 adults were treated for their alcohol problems at conventional services. User profile and site usage had been similar during the earlier pilot phase. Results from surveys sent to pilot programme completers indicated that three quarters had never previously sought help for their drinking.

Steroids are linked to manic episodes, depression, suicide, psychotic episodes and increased aggression and hostility, occasionally triggering violent behavior, including murder.

Researchers at Uppsala University in Sweden studied the relationship between crime and steroid use in 1,440 Swedish residents tested for the drugs between 1995 and 2001 from clinics, including substance abuse facilities, as well as police and customs stations.

Of those involved in the study, 241 tested positive, with an average age of about 20.
The research team found those who tested positive for steroid use were roughly twice as likely to have been convicted of a weapons offense and one-and-a-half times as likely to have been convicted of fraud.

When the researchers excluded people from substance abuse facilities from their analysis the connection with armed crime remained, but the link between steroid use and fraud disappeared.
While steroids are linked with outbursts of uncontrolled violence known as “‘roid rage,” they did not appear to be connected with sexual offenses, violent crimes such as murder, assault and robbery, or crimes against property such as theft.

This investigation instead reveals that steroid use may be linked with premeditated crimes—those involving preparation and advance planning.
One explanation the researchers suggest for the findings is that criminals involved in serious crimes such as armed robbery or the collection of crime-related debts might benefit from the muscularity, heavy build and increase in aggression that comes with steroid use.

The scientists report their findings in the November issue of the Archives of General Psychiatry.

How serious is the child and teenage alcohol problem in your area?

More than 20 children and teenagers are being treated in hospital every day for alcohol-related illnesses, including mental disorders, poisoning and liver disease, according to newly released official data.

The figures, labelled “staggering” by one of Britain’s most senior doctors, show that in the year 2005-6, during which Labour introduced 24-hour drinking, the number of under-18s seeking treatment for alcohol-related health problems leapt by 13% to 8,894, an average of 24 a day.

The research, released in parliament by Caroline Flint, the health minister, shows that the number treated has gone up by 33% since Labour came to power in 1997.

Professor Ian Gilmore, president of the Royal College of Physicians, said: “This is a staggering rise and it is only the tip of the iceberg.
“Drinks sold by supermarkets and off-licences are cheaper than ever, and those shops have been at the front of the queue for 24-hour licences, so it has never been more available.

“The younger they drink, the more likely they are to have alcohol-related problems later in life. It is now commonplace to see men and women in their twenties with end-stage alcoholic liver damage.”
The disease figures released by Flint do not include those people treated for injuries sustained in incidents such as drunken fights or drink-driving.

Separately, the government has released figures for patients treated for alcohol-related conditions in accident and emergency wards, showing that alcohol-related medical emergencies and hospital treatments have doubled since 1997.

In some parts of the country the rise is even steeper. The worst areas include the region formerly covered by Cheshire and Merseyside Strategic Health Authority, where 742 young people were treated last year, a rise of more than 25% in just a year. In Northumberland, Tyne and Wear, the number went up by a quarter.
By contrast, some southern health authorities experienced an improvement. In Bedfordshire and Hertfordshire, for example, there were only 119 cases, a fall of 30%.

In addition to the figures for children and teenagers, the Department of Health data also show that the number of people aged 18 and over treated for alcohol-related illness has gone up from 124,925 to 253,603 since 1997, a rise of more than 100%.
The data, released in a written answer, appear to contradict the government’s claims that the liberalisation of pub opening and supermarket off-sales time would lead to more responsible drinking.

They bear out research published earlier this year by the British Association for Emergency Medicine, which found an increase in alcohol-related injuries treated in hospital among all age groups since the change to the drinking laws.

Ahead of its launch of 24-hour opening in November 2005, the government assured voters that there would be tougher controls on underage drinking.
It announced on-the-spot fines for children buying alcohol and tougher penalties for staff serving them.
Tessa Jowell, the culture secretary, said at the time: “The result will be more freedom for responsible adults and tougher treatment for the yobbish minority.”

Labour’s approach to teenage drinking has not always lived up to the responsible image that it likes to project.
In the run-up to the 2001 general election, the party sent text messages to first-time voters telling them, “Don’t give a XXXX for last orders? Vote Labour”. This was an allusion to advertisements for Castlemaine XXXX, the Australian beer.

Dr Gray Smith-Laing, a consultant at the Medway Maritime hospital in Gillingham, Kent, who treats patients with liver disease, said last week: “What we’re seeing is the numbers going up, the age coming down.

“The idea that (24-hour opening) just smooths out the drinking and people drink the same amount over a longer period of time is complete rubbish.”
The Department of Health says that levels of binge drinking have peaked and new facilities such as walk-in centres could explain the growth in treatment for drink-related injuries.

The department said yesterday: “The increased attendances at A&E departments, as seen in recently published figures, began some years ago. Evidence suggests that increased rate of growth of attendances predates the change in licensing laws by several years. In fact, this year growth has actually slowed.”

Q: How can I tell if my child has been using marijuana?
A: There are some signs you might be able to see. If someone is high on marijuana, he or she might:

• Seem dizzy and have trouble walking;
• Seem silly and giggly for no reason;
• Save very red, bloodshot eyes; and
• Have a hard time remembering things that just happened.
When the early effects fade, the user can become very sleepy.

Parents should be aware of changes in their child’s behavior, although this may be difficult with teens. Parents should look for withdrawal, depression, fatigue, carelessness with grooming, hostility and deteriorating relationships with family members and friends.

In addition, changes in academic performance, increased absenteeism or truancy, lost interest in sports or other favorite activities, and changes in eating or sleeping habits could be related to drug use. However, these signs may also indicate problems other than using drugs.

In addition, parents should be aware of:

• Signs of drugs and drug paraphernalia, including pipes and rolling papers;
• Odor on clothes and in the bedroom;
• Use of incense and other deodorizers;
• Use of eye drops; and
• Clothing, posters, jewelry, etc., promoting drug use.

Support for legalising cannabis has dropped from more than a third of people in Scotland to less than a quarter, a study has suggested.
However, most people made a distinction between cannabis and other drugs.
The findings come in a Scottish government study into the public’s attitudes towards illegal drugs and drug misuse.
It showed 47% of people knew someone who had tried illegal drugs, up from 41% between 2001 and 2009.
Statistics from the British Social Attitudes Surveys in the 1980s and 1990s, along with the Scottish Social Attitudes Survey 2001, indicated an increasingly tolerant attitude towards the legalisation of cannabis.
The results from the Scottish Social Attitudes Survey 2009 have now suggested a reverse in this trend.
Mental health
Support for legalising cannabis fell from 37% in Scotland in 2001 to 24% in 2009. Among those who had themselves tried cannabis, support for its legalisation fell from 70% to 47% over the same period.
The views were accompanied by a hardening of attitudes towards prosecution for the possession of cannabis.
The report found the trend may be linked to the mental health debate surrounding new stronger forms of cannabis, called skunk, or it may reflect a changing trend in attitudes towards illegal drugs in general.
In 2008 the government introduced a new strategy to tackle the nation’s drug problems by focusing on “recovery and helping people live drug-free lives”.
In principle this appeared to be supported by the Scottish public, with 80% saying “the only real way of helping drug addicts is to get them to stop using drugs altogether”.
How this should be done was not so clear, the report found.
There was widespread support for enforcement, with only 16% of people agreeing that personal use of heroin should not result in prosecution.
Although education was generally supported as the focus of drugs policy, only 44% of people believed this “education” should involve young people being given more information on how to use drugs more safely.
The survey also indicated that communities with higher signs of heroin use were more likely to be comfortable living near a recovering heroin user. This may mean that actual contact with such issues helps to allay public anxiety, it suggested.

Over the past ten days, 40 reports were received by the National Poisons Information Centre regarding persons suffering severe adverse reactions attributed to using a new head shop substance “WHACK”.
The majority of these individuals are young males in their twenties. They live in different parts of Ireland with 20 presenting in the mid-Western region. They have suffered a range of symptoms including increased heart and breathing rates and raised blood pressure. Emergency Physicians and GPs have described that the majority suffered from differing levels of anxiety with at least 7 cases experiencing psychotic episodes. This psychosis is severe and is proving difficult to treat.

The National Poisons Information Centre, the Forensic Science Laboratory, the Irish Medicines Board and others are monitoring closely the emergence of any new psychoactive substances.

On the 11th May 2010, the Government brought in new legislation. This legislation has brought under control approximately 200 individual substances and covers the vast majority of products of public health concern, which were on sale in head shops.

In addition to the recent controls on legal highs introduced by the Minister for Health and Children, the Minister for Justice and Law Reform is bringing forward the Criminal Justice (Psychoactive Substances) Bill 2010 which aims to ensure that the sale or supply of substances which may not be specifically proscribed under the Misuse of Drugs Act, but which have psychoactive effects, will be a criminal offence.

The advice from the HSE is not to try this dangerous drug or other similar substances as the effect on an individual can impact significantly on one’s health.

Troubled sleep is a commonly cited consequence of adolescent drug use, but it has rarely been studied as a cause. Nor have there been any studies of the extent to which sleep behavior can spread in social networks from person to person to person. Here we map the social networks of 8,349 adolescents in order to study how sleep behavior spreads, how drug use behavior spreads, and how a friend’s sleep behavior influences one’s own drug use. We find clusters of poor sleep behavior and drug use that extend up to four degrees of separation (to one’s friends’ friends’ friends’ friends) in the social network. Prospective regression models show that being central in the network negatively influences future sleep outcomes, but not vice versa. Moreover, if a friend sleeps ≤7 hours, it increases the likelihood a person sleeps ≤7 hours by 11%. If a friend uses marijuana, it increases the likelihood of marijuana use by 110%. Finally, the likelihood that an individual uses drugs increases by 19% when a friend sleeps ≤7 hours, and a mediation analysis shows that 20% of this effect results from the spread of sleep behavior from one person to another. This is the first study to suggest that the spread of one behavior in social networks influences the spread of another. The results indicate that interventions should focus on healthy sleep to prevent drug use and targeting specific individuals may improve outcomes across the entire social network.

An Evaluation of the Kids, Adults Together Programme (KAT)

INTRODUCTION
A key influence on the timing of young people’s first alcohol use is the family (Spoth et al. 2002) and a number of substance misuse prevention programmes (mainly in the USA) have tried to influence families. Most are based in schools, which potentially provide an efficient way to reach large numbers of young people and their families (Bryan et al. 2006). However, in practice, school-based initiatives have not always managed to engage significant numbers of parents (Lloyd et al. 2000; Rothwell et al. 2009; Stead et al. 2007; Ward and Snow 2008).
This report describes the findings from an exploratory evaluation of a new school-based alcohol misuse prevention programme – Kids, Adults Together (KAT), which engaged with parents as well as children. The programme comprised a classroom component for children, a family fun evening, and a DVD. The research study evaluated the development and early implementation of KAT, and aimed to establish the theoretical basis for the programme. It explored implementation processes and acceptability, and identified plausible precursors of the intended long-term outcome which could be used as indicators of likely effectiveness.
METHODS
Mixed qualitative data-collection methods were used during two phases of evaluation. The first phase of the evaluation investigated how KAT had originated and developed; its relationship to existing evidence and theory; and its aims. Methods used were an analysis of thirty-two documents selected by the programme organizers and meant to provide an ‘audit trail’ of programme development up until the start of the evaluation; a literature search; and interviews with six members of the working group who had been involved in setting up the programme, the programme organiser and his assistant, the KAT DVD producer and the organiser of the Australian PAKT programme (on which KAT is based).
The second phase comprised observation of the classroom preparation and KAT family events in two pilot schools; focus groups with forty-one children; interviews with both head teachers and with teachers who delivered the classroom preparation; follow-up interviews with the programme organisers and six Working Group members; interviews with twelve parents who attended the KAT family events; and a questionnaire for parents of all 110 children who had been involved in the classroom preparation. There were two rounds of focus groups and parent interviews: the first as soon as possible after the KAT event at each school and the second months later.
Programme aims
The main aim of KAT was identified as reducing the number of children and young people who engaged in alcohol misuse. Exploration of the programme’s implementation suggested that family communication should be reaffirmed as its primary objective. This was consistent with the social development model (Catalano and Hawkins 1996) which links family communication with children’s alcohol-related behaviour later in life.
Acceptability
KAT achieved high levels of acceptability among pupils, parents and school staff. Parents enjoyed the fun evening, and thought it was delivered in an, engaging and non lecturing way. Participants thought it was good that the KAT programme had been run in the school setting, and felt that such work should be delivered to children at a young age. Staff in both pilot schools believed that the way in which the evening was promoted as an opportunity for parents to find out what their children had been working on helped avoid a perception that the fun evening was designed to lecture parents.
INITIAL IMPACT
Communication
The KAT programme’s most significant and persistent impact on communication was the effect on family conversations about parental drinking. Many children who thought their parents drank too much alcohol reported trying to change their (parents’) behaviour.
The classroom preparation was effective in promoting communication about alcohol issues amongst members of the class but outside the classroom, its effect was minimal, and until the work had culminated in the fun evening, few children said much at home about it. Most children were very keen to go to the fun evening, to show off their work, to see what it was like and to enjoy the refreshments and entertainment. Many put pressure on their parents to attend.
The fun evening acted as a catalyst for setting off conversations about what children had done in the classroom and activities during the evening. The DVD was effective in extending the influence of the programme beyond the school-based components.
Knowledge
Both children and parents reported having gained new knowledge about alcohol as a result of their involvement with the KAT programme.
Attitudes
There was little evidence that involvement in KAT (as a whole or its constituent components) had led to changes in parents’ or children’s attitudes to alcohol consumption. Overall the children held critical attitudes towards alcohol and the effects which its consumption might lead to. Most parents who were concerned about the dangers of alcohol and the use of alcohol by their children held pre-existing concerns or attitudes.
Awareness
KAT raised children’s and parents’ awareness of issues relating to alcohol and some parents had thought about their own drinking practices, particularly how drinking alcohol in front of their children could influence them.
Intention
Evidence from participants suggested that KAT had only a small effect on intentions regarding future behaviour. These intentions were often stimulated by specific aspects of the programme such as the DVD or leaflets in the goody bag.
Behaviour
There was evidence from some parents and children at both schools that drinking behaviour of parents and other family members had changed as a result of KAT. The effect was not confined to those who had attended the fun evening, suggesting that KAT was able to influence communication within wider networks of family and friends.
IMPLICATIONS
The report highlights five main findings from the evaluation of KAT:
1. KAT has demonstrated promise as an alcohol misuse prevention intervention through its short term impact on knowledge acquisition and pro-social communication with family networks
2. The interaction between the programme’s core components (classroom activities, family fun evening and the programme DVD/goody bag) appear to have been integral to the impact on knowledge acquisition and communication processes that occurred within participating families
3. The timing of KAT (its delivery to children In primary school Years 5 and 6) is appropriate both because it precedes the onset of drinking (or regular drinking), and because it engages families whilst they are still a key attachment and influence in young people’s lives
4. KAT achieved high levels of engagement and acceptability among parents, and this included some families with problems/support needs in relation to alcohol
5. Engagement levels among parents were higher among mothers than fathers. The research was not able to explore the in-depth experiences of those parents/carers who did not or could not attend the KAT fun evening
The following five recommendations are made for the future development and evaluation of KAT:
1. Further research is needed to refine and develop the theoretical model of how KAT works, whether short term changes in knowledge, communication and behaviour are sustained over the longer term, and how these processes might reduce alcohol misuse
2. KAT needs to be delivered and evaluated in different school contexts to further test its underpinning model, and explore the acceptability and local adaptation of the programme within these settings
Future research needs to explore in more detail the reach of the programme (including the engagement of fathers), examine what barriers to attendance might exist and put in place strategies to minimise them
3. Future stages of implementation should clarify if KAT specifically aims to reach families with problems/support needs in relation to alcohol, or whether it is intended as a primary prevention intervention for general school populations
4. It is important to address the support needs of children whose attempts to discuss issues raised by KAT (particularly around parental drinking) are rejected or not received positively by their parents

It is well-known that maternal smoking during pregnancy can have long-term effects on the physical health of the child, including increased risk for respiratory disease, ear infections and asthma. New research shows that prenatal smoking also can lead to psychiatric problems and increase the need for psychotropic medications in childhood and young adulthood.

Finnish researchers found that adolescents who had been exposed to prenatal smoking were at increased risk for use of all psychiatric drugs especially those uses to treat depression, attention-deficit/hyperactivity disorder (ADHD) and addiction compared to non-exposed youths. The study was presented Tuesday, May 4 at the Pediatric Academic Societies (PAS) annual meeting in Vancouver, British Columbia, Canada.

“Recent studies show that maternal smoking during pregnancy may interfere with brain development of the growing fetus,” said Mikael Ekblad, lead author of the study and a pediatric researcher at Turku University Hospital in Finland. “By avoiding smoking during pregnancy, all the later psychiatric problems caused by smoking exposure could be prevented.”

Ekblad and his colleagues collected information from the Finnish Medical Birth Register on maternal smoking, gestational age, birthweight and 5-minute Apgar scores for all children born in Finland from 1987 through 1989. They also analyzed records on mothers’ psychiatric inpatient care from 1969-1989 and children’s use of psychiatric drugs.

Results showed that 12.3 percent of the young adults had used psychiatric drugs, and of these, 19.2 percent had been exposed to prenatal smoking.

The rate of psychotropic medication use was highest in young adults whose mothers smoked more than 10 cigarettes a day while pregnant (16.9 percent), followed by youths whose mothers smoked fewer than 10 cigarettes a day (14.7 percent) and unexposed youths (11.7 percent).

The risk for medication use was similar in males and females, and remained after adjusting for risk factors at birth, such as Apgar scores and birthweight, and the mother’s previous inpatient care for mental disorders.

Smoking exposure increased the risk for use of all psychotropic drugs, especially stimulants used to treat ADHD (unexposed: 0.2 percent; less than 10 cigarettes/day: 0.4 percent; and more than 10 cigarettes/day: 0.6 percent) and drugs for addiction. An increased risk for use of drugs to treat depression also was seen (unexposed: 6 percent; less than 10 cigarettes/day: 8.6 percent; and more than 10 cigarettes/day: 10.3 percent).

“Smoking during pregnancy is still quite common even though the knowledge of its harmful effects has risen in recent years,” Ekblad concluded. “Recent studies have shown that smoking during pregnancy has negative long-term effects on the health of the child. Therefore, women should avoid smoking during their pregnancy.”

We know that there are people alive today who find it impossible to quit different kinds of behaviour once they have started it. What is it that makes one person quit cold turkey, and another smoke even while they are being treated for cancer?

Is there an addiction gene? Addiction in the genes is a hotly debated subject among scientists and researchers.

Scientists and researchers are going further back than ever before to unearth present truths. Addiction runs in the family. Again and again, they have found addictive behaviours carried down the family tree. This was their first clue that addiction may be hereditary.

There doesn’t appear to be a single ‘addict’ gene that causes specific types of people to fall into the addiction trap. There are however, several that combine to form a strong susceptibility to the behavioural patterns that addict’s exhibit. This is the addiction and genetics debate.

When a person with these genetic markers is exposed to a drug, or a habit, it can change the chemistry in their brain. This change leads to compulsive behaviour and eventual addiction. We are familiar with the concept that some illnesses – both physical and mental – can be hereditary, but it appears that this can also be applied to addiction.

Naturally, even if addiction is in the genes, there are other external factors that play their part. Why is it, for example, that a man becomes a drug addict, when his sister has never so much as smoked? External circumstances, stimuli and environmental factors also play their part in affecting people who are genetically prone to addiction.

The addiction and the genetic factor discussion will play on for years to come. The science is still quite new, and there are those out there that would prefer to blame addiction on personality disorders instead of genetics. Even if a definitive link is found, there is a still a long way to go before this information can be used to treat addiction sufferers and their families. For the time being at least, traditional addiction treatment and rehabilitation is still the most effective way to proceed.

Alcoholism, gambling, sexual and drug addiction could all be the result of inherited genes and generations of vulnerability. If you believe that addiction runs in the family, analyse yourself honestly. If it appears that you have a vulnerability to addictive behaviour, seek professional assistance. Obtaining assistance early on may help to limit any long-term damage.

The brain’s nucleus accumbens (NAC) is a core region of the mesocorticolimbic dopaminergic system and is interconnected with the ventral tegmental area (VTA) and the prefrontal cortex. The mesocorticolimbic system is thought to be central to the reinforcing effects of many drugs and plays an important role in addiction. A new study has found that alcohol abuse elevated the expression of a distinct set of genes in the NAC and VTA, while nicotine blunted this effect in the VTA.

Results will be published in the July 2010 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.

“In spite of their differences in pharmacology, alcohol and tobacco consumption are often intimately linked,” said Traute Flatscher-Bader, a postdoctoral research fellow at The University of Queensland and corresponding author for the study. “Nonetheless, the molecular mechanisms that underlie alcohol and nicotine abuse, and particularly their co-abuse, are still incompletely understood.”

“One thing that researchers have encountered is that it is often difficult to find ‘pure’ alcoholics, that is, alcoholics that only abuse alcohol and nothing else,” agreed Simon Worrall, director of postgraduate coursework programs in molecular biology at The University of Queensland. “Many alcoholics are poly-drug abusers, with the most common other drug being nicotine. Thus, many studies which have studied the effects of alcohol on the brain and other organs have been compromised because they have not taken account of the effects of nicotine addiction which is often superimposed on the effects of alcohol addiction.”

In the first part of the current study, Flatscher-Bader and her colleagues used DNA microarray technique to study the expression of many thousands of genes in the brains of non-smoking and smoking alcoholics and non-drinking smokers.

“We examined the impact of alcoholism and smoking on gene expression in the NAC in 20 chronic alcohol abusers and controls with and without recent smoking history,” said Flatscher-Bader. “The results revealed that in this brain region, the abuse of alcohol and nicotine had distinct effects on the expression of genes. In addition, altered expression of a number of genes was associated with both alcohol and nicotine abuse. Within the latter group was a set of genes which play a crucial role in a molecular pathway regulating cell structure.”

The researchers then went on to investigate in more detail the altered expression of six selected genes within the pathway regulating cell structure in two brain regions, using 30 cases comprised again of smoking and non-smoking controls and alcohol abusers. For this part of the study they used the method called “real time polymerase chain reaction.”

“This expanded investigation revealed that one of the genes, called RHOA, was elevated by alcohol abuse and its highest expression was evident in the smoking alcoholics in both brain regions,” said Flatscher-Bader. “The RHOA gene had previously been implicated in the initiation of tobacco smoking. In the NAC, the expression of a further four of the six selected genes was increased by alcohol abuse. Interestingly, the highest expression for each of the genes in the NAC was in the smoking alcoholics. In the other brain region called the VTA, alcohol abuse had a similar effect and elevated the expression of all six selected genes. In contrast to the NAC, however, concurrent smoking dampened the induction of five of these alcohol-sensitive genes in the VTA.”

“Many studies have analyzed the changes in gene expression in this brain system to try to untangle the molecular pathology of alcohol addiction,” said Worrall, “but this is amongst the first to take into account the effect of co-administration of nicotine with alcohol.

Flatscher-Bader stressed that there are several cell types in the brain and there are several steps between gene expression and impact on cell structure and function. “It has to be emphasized that our study is important as a first step in identifying molecular pathways underlying the effects of alcohol abuse and smoking and their co-joint abuse on the human NAC and VTA, “she said. “It now needs to be tested if our findings are, indeed, associated with changes to neuronal structure and function.”

“A better understanding of the molecular basis of withdrawal may help in the development of new treatments to ameliorate the symptoms,” added Dr Worrall. “Not many previous studies took into account the potential effects of nicotine addiction that may be superimposed on top of those from alcohol, so these results may help clinicians better use present therapy/drugs to treat patients abusing both alcohol and/or nicotine and may also lead to the development of new drugs.”

Few studies can manage the painstaking analyses needed to identify what makes for successful counselling. This Swiss study broke new ground in dissecting why some brief interventionists had far better results than others with risky drinking A&E patients.
Abstract The featured report is one of several from a study of brief advice to heavy drinkers among injured adult patients attending a Swiss emergency department. Among 8439 patients, 1472 heavy drinkers were identified by a health screening survey, of whom 987 joined the study. They were randomly allocated to carry on as usual, to also be assessed by a researcher for about half an hour, or in addition to receive about 15 minutes of advice on drinking immediately after assessment. Adopting the style of motivational interviewing, this compared the patient’s drinking with national norms and led the patient to consider the pros and cons of their drinking and their readiness to change, culminating if appropriate in a setting a goal for change. Over the following year, this typical brief intervention format did not lead to greater reductions in drinking. About two-thirds of the patients continued to drink heavily regardless of advice and/or assessment.
During a period of the study and when patients allowed, intervention sessions were audio-taped. 97 sessions could be rated for the degree to which the counsellor adhered to a motivational style, and for comments from the patient indicative of their ability and willingness to change their drinking. Of these ratings, an initial analysis found that only the patient’s expressed degree of ability to change was related to later drinking; none of the counsellor’s behaviours was significantly linked. However, this analysis tried to separately link each behaviour (in)consistent with motivational interviewing’s principles with drinking. The possibility remained that combining these behaviours to characterise the counsellor’s overall style would yield significant results.
This was the approach taken in two further reports, one of which was the featured report. An earlier analysis established that counsellor comments consistent with the style of motivational interviewing were most likely to elicit positive statements about changing their drinking from the patient. The featured report related the same (and other) measures of counselling style to later drinking, limiting itself to interventions conducted by five counsellors with similar qualifications and experience and uniform preparatory training. Despite this they differed significantly in the their patients’ weekly drinking at the 12-month follow-up, and in the degree to which this represented an improvement on the amount they were drinking on entry to the study. At the extremes were one counsellor whose patients ended up drinking on average 18 UK units more per week, while another registered an average nine unit reduction.
These differences were at least partly accounted for by how far the counsellor was able to actually deliver the intervention in a motivational style. Drinking reductions were greater the more the counsellor demonstrated acceptance of the patient, conducted the intervention in the intended spirit, made more comments consistent versus inconsistent with a motivational approach, avoided inconsistent comments, elaborated on the patient’s comments rather than simply reflecting them back, and reflected back the patient’s comments with or without elaboration rather than asking questions. Empathy levels narrowly missed featuring among these strong and statistically significant links. These same attributes tended to even out the relationship between the patient’s expressed feelings of (in)ability to change and how much they did change their drinking over the 12 months. Highly skilled counsellors had good outcomes almost regardless of the patient’s doubts. The less skilled were effective mainly with patients who already expressed high levels of ability to change.
While accepting the need for replication in a larger study, for the authors their results suggested that an optimal combination of motivational interviewing skills results in better drinking outcomes, regardless of whether the patient is confident (or expresses confidence) in their ability to cut back. The pattern of results across all the reports from the study implies that training should focus on developing an overall approach consistent with motivational interviewing (with a particular focus on avoiding inconsistent behaviour) rather than on the frequent use of particular ‘micro’ techniques. Since training was equalised in the study, it also seems important to select staff with a ‘natural’ ability to adhere to the spirit of motivational interviewing when counselling patients.
These comments are more fully explained and referenced in the associated background notes. This study is one of the few in substance misuse to deeply address how therapists relate to clients in ways which promote positive change. It seems the first to depth-analyse interactions during a brief intervention which (from the patient’s point of view) unexpectedly addresses their drinking while they are seeking help for something else entirely. The implication is that in this situation, the impact of motivational interviewing with heavy drinkers depends on the ability of the counsellor to embody the spirit of the approach, not in minute or tick-box detail, but in broad-brush and consistent application. Given this spirit, as intended, patients in general respond not by defensively deflecting this uncalled-for advance, but by re-evaluating their drinking in ways which lead to a lasting reduction.
As intended by its creators, the findings show that true-to-type motivational interviewing can counter low motivation and doubts, elevating outcomes to near those of the most promising patients. While training doubtless played its part in developing this ability, still it left big differences between counsellors, who presumably varied in the degree to which they could implement what they learned. The more ‘trainable’ dimensions of the frequency of recommended types of comments were relatively uninfluential, the more nebulous ‘spirit’ dimensions more important. Despite expert training and supervision, the result was some therapists whose patients drank more than they did before, others whose patients drank less, a finding which turns the spotlight on staff recruitment. The implication is that without appropriate recruitment, much of the effort put in to training and supervision will be wasted.
The same message emerged from a study of motivational interviewing training which found that initial gains in skills had waned two months later. However, this was not the case for the addiction and mental health clinicians who, even before training, had been more proficient than the other trainees would be after training. Not only did these ‘natural experts’ start from a higher level, they went on to absorb and retain more of what they had learned.
How easy it is to find such people must be a concern. In the featured study all the counsellors were clinical psychologists educated to master degree level, trained by an experienced therapist and supervised throughout using actual client session recordings or observations. This exceptional combination of qualifications, training and ongoing support still resulted in just one of the therapists having a marked positive effect on drinking.
While these are important findings with echoes in other studies, inevitably they stand on a narrow and inadequate evidence base. Studies which probe deeply enough to make sense of what is going on in therapy require labour-intensive analyses, so tend to be limited to perhaps one site and a few therapists, by-products of studies designed to address the effectiveness not of therapists, but of therapies.
Particular caution is needed before assuming that the implications extend to substance misuse treatment. The dynamics in the emergency department are likely to be very different from those in substance misuse treatment clinics, whose patients have already acknowledged their problems and decided at least to give treatment a try. In this situation, the overwhelming influence is the strength of the patient’s resolution. Therapists can still make a noticeable and sometimes substantial difference, but generally more in terms of whether clients want to extend the relationship by staying in treatment, than in whether they change their substance use.
Among several less serious concerns, the featured study’s main weakness is the non-random allocation of patients to therapists, meaning varying caseloads might have influenced the therapists’ performances. However, this does not seem to account for the findings. Confidence in these and in their generalisability is increased by findings from different contexts with similar implications.
Across a range of caseloads, one review of how motivational interviewing works has highlighted (as the featured study did) the importance of therapists avoiding behaviours inconsistent with a motivational approach. Most relevant however are other brief intervention studies of patients not seeking treatment. These confirm that in such circumstances, some therapists are much more able than others to realise the potential of a motivational approach. Avoiding directive and confrontational behaviour seems particularly important with people who when they attended their GP, emergency department, or college, were not expecting their substance use to be addressed at all, let alone in such terms. Even patients who, while not seeking treatment, have volunteered for a check-up of their drinking habits, have reacted badly to such approaches. As in the featured study, other studies have also found that embodying the overall spirit of the approach is related to good outcomes, while the sheer quantity of ‘correct’ micro-behaviours is not. In one study the least effective of three therapists conducting motivational interventions for heavy drinking was also the one who most often used specific recommended techniques.
The dynamics of the therapist-patient encounter seem to differ in a treatment context. Like brief intervention studies, studies of patients actually seeking treatment for substance use problems have confirmed the importance of the overall spirit of the approach rather than micro measures of the frequency of correct therapist behaviours. However, they have been less clear about the damaging impact of behaviours inconsistent with a motivational approach. Within an overall supportive and accepting context, patients react well, or at least, not badly, to a degree of confrontation and caring concern, even if the patient’s permission has not been sought. With clients seeking help for a serious substance use disorder, there is more reason to show concern, be directive, and to warn about possible consequences. Patients who themselves are concerned and seeking direction might see the total absence of such comments from their therapists as withholding their true feelings, perhaps even as uncaring. For these patients the absence of a directive approach can be positively damaging, while those who like to see themselves as in control react badly to directive therapists.

Combining a randomised trial with a ‘real-world’ test, studies of the Dutch Drinking Less programme have gone further than any others to establish the beneficial impacts of web-based alcohol self-help interventions.

Abstract

The study was a ‘real-world’ test of a promising Dutch internet-based self-help intervention for problem drinking. A previous randomised trial employing the methodological safeguards possible in tightly controlled research (particularly the recruitment of a comparison group not given access to the intervention) had established that the intervention reduced drinking. At issue in the featured study was whether similar drinking reductions would be seen when the intervention was made freely available to the general public. If they were, then the assumption could be made that these too were caused by having access to the intervention.

Drinking Less is an on-line, interactive programme with no personal therapist input. Aimed at risky drinkers among the general adult population, the intervention is based on principles derived from motivational interviewing, cognitive-behavioural therapies and self-control training. Its home page offers links to alcohol-related information, treatment services, a discussion forum, and the Drinking Less self-help programme, the core of the intervention. Over a recommended six weeks (though this is entirely up to the user) the programme guides visitors in preparing to change their drinking, setting goals , implementing change, and finally sustaining it, preferably by drinking within recommended limits.
The earlier trial had found that six months later, at least 17% of adult problem drinkers randomly allocated to this intervention had reduced their drinking to within Dutch guidelines, compared to just 5% allocated to an on-line alcohol education brochure. Before the study, both groups had averaged about 55 UK units a week. At follow-up, the Drinking Less group had cut consumption to about 36 UK units a week, but the brochure group had barely changed.
The featured study monitored what happened when over 10 months spanning 2007 and 2008 the web site was advertised to the Dutch public. During this time round 27,500 people visited the site, of whom 1625 signed up for the self-help programme, accessing it on average 23 times. Typically they were well educated, employed, middle-aged men. On average they drank about 50 UK units a week, and nearly all who completed the on-line AUDIT screening questionnaire scored in a range indicative of alcohol abuse or dependence.
During the first seven of the 10 months, 378 of site visitors who signed up to the Drinking Less programme also agreed to participate in research to assess its impact. On average they drank roughly the same amount (95% exceeded Dutch guidelines) as all 1625 who signed up and were also similar in age, sex, employment, and motivation to change. Despite some statistically significant differences, they were also broadly similar to participants in the earlier randomised trial. Over 8 in 10 had never received professional help for their drinking. A few weeks later a survey suggested that after signing up, nearly 9 in 10 went on to use the programme, though generally only a few times.
Of the 378 in the baseline sample, 153 responded to an on-line follow-up survey six months later. Before signing up to the programme, just 4% had confined their drinking within Dutch guidelines; six month later, 39% did so. They had also nearly halved their average consumption from 50 UK units to 27. On the ‘fail-safe’ assumption that the intervention had no impact on people who were not followed up, still the drinking reductions were statistically significant; from 5%, the proportion drinking within guidelines rose to 19%, and consumption fell from 51 UK units to 42.
Next the analysts compared these results with those from the six-month follow-up in the randomised trial. Based only on respondents to the follow-up surveys, and adjusting for differences between the samples, in the ‘real-world’ test over twice as many (unadjusted figures 36% v. 19%) people moved to drinking within Dutch guidelines. When the assumption was made that in both trials the intervention had no impact on people not followed up, the figures still favoured the ‘real-world’ test (15% v. 10%), but the difference was no longer statistically significant.
The researchers concluded that the featured study had shown that the benefits established by the randomised controlled trial would be sustained when the intervention was made routinely and generally available to the public. The expected throughput of 3000 Drinking Less programme users a year would amount to nearly 3% of the country’s problem drinkers who would otherwise not have received professional help. Probably because they require the drinker to take the initiative and visit the site, such interventions reach people who, compared to the totality of problem drinkers, are more likely to be women, employed, highly educated, and motivated to change their drinking. Given its low cost per user, this type of intervention seems to have a worthwhile place in a public health approach to reducing alcohol-related problems.
Though only a minority of site visitors may sign up for web-based alcohol programmes, nevertheless the numbers engaged can be very large, and the risk-reductions seem of the order typical in studies of brief advice to drinkers identified in health care settings. In these settings screening programmes typically identify people who are not actually seeking help for drinking problems – ‘pushing’ them towards intervention and change – while web sites ‘pull’ in people already curious or concerned about their drinking. As such these two gateways can play complementary roles in improving public health and offering change opportunities to people who would not present to alcohol treatment services. However, in Britain and elsewhere, both tactics reach only small fractions of the population who drinking excessively, leaving the bulk of the public health work to be done by interventions which drinkers generally cannot avoid and do not have seek out, such as price increases and availability restrictions.
With its combination of a randomised trial and a ‘real-world’ test, the featured research programme has gone further than any other in establishing the beneficial impacts of web-based alcohol interventions. However, largely because many site users do not complete research surveys, it remains impossible to be sure that the results seen in such studies will be replicated across the entire usership of the sites. Details below.

Strengths and limitations of the featured study

The featured study’s combination of a randomised trial with all its methodological safeguards, and a ‘real-world’ trial approximating normal conditions, affords what seems to be the best indication to date of the contribution web-based self-help interventions could make to reducing heavy drinking and associated health risks. However, its twin pillars are weakened by the fact that many people either did not join the studies or did not supply follow-up data; those who did may not have been typical of all the people who might access such sites. In the randomised trial, 40% of the baseline sample did not complete the six-month follow-up survey, and in the featured study, nearly 60%. Though on the measures taken by the study the respondents generally seemed typical of the baseline sample, clearly something was sufficiently different to cause them to respond while the others did not. In both studies this problem was catered for by assuming that non-responders were also non-changers. Though this almost certainly underestimated the impact of the intervention, still in both there remained significant and worthwhile improvements.
What could not be catered for in either study was the degree to which people who join such studies differ from the much greater number who would use the web sites, but decline participation in research. This problem was especially apparent in the featured study, in which it seems that around 6% of site visitors signed up for the self-help programme. Of these, perhaps a third or slightly more of the people who signed up for the programme during the relevant period also agreed to participate in the research. In some important ways (including amount drunk and motivation to change) they seemed similar to the bulk of programme sign-ups, though the researchers suspect they were more likely to have engaged with the programme.

Opening more doors to change for more people

A review of computer-based alcohol services for the general public has rehearsed the advantages: immediate, convenient access for people (the majority in developed nations) connected to the internet; consequently able to capitalise on what may be fleeting resolve; anonymous services sidestep the embarrassment or stigma which might deter help-seeking; such services are available to people unwilling or less able to talk about their problems to a stranger; generally they are free and entail no travel costs or lost income due to time off work; very low operating cost per user if widely accessed; easily updated. In consumption terms, the drinking problems of web site users are comparable to those of drinkers who seek treatment, yet few have received professional help, perhaps partly because their higher socioeconomic status and greater resources have enabled them to restrict the consequential damage. People who actually engage with web-based assessments of their drinking problems have more severe problems than those who just visit and leave. Including the randomised trial which paved the way for the featured study, the review found eight studies which evaluated the effectiveness of computer-based interventions for the general public. In all but one the users significantly improved on at least one of the alcohol-related measures recorded by the studies.
A particular role for alcohol self-help sites may be to offer an easy, quick and accessible way to for drinkers to actualise their desire to tackle their problems, especially when that desire is allied with the resources to implement and sustain improvements without face-to-face or comprehensive assistance. After conducting the Project MATCH trial, some of the world’s leading alcohol treatment researchers argued that “access to treatment may be as important as the type of treatment available”. The implication is that in cultures which accept ‘treatment’ as a route to resolving unhealthy and/or undesirable drinking, having convincing-looking and accessible ‘treatment doors’ to go through may be more important than what lies behind those doors, as long as this fulfils the expectations of the client or patient. This is likely to be especially the case for people who retain a stake in conventional society in the form of marriages, jobs, families, and a reputation to lose. These populations – the kind the featured study suggests are attracted to self-help alcohol therapy web sites – have more of the ‘recovery capital’ resources needed to themselves do most of the work in curbing their drinking.

The British Down Your Drink site

The best known British alcohol self-help web site is the Down Your Drink site run by a team based at University College London, an initiative originally funded by the Alcohol Education and Research Council and now by the Medical Research Council’s National Prevention Research Initiative. In 2007 this was revised to offer set programmes from a one-hour brief intervention to several weeks, but also to generally give the user greater control over the use they made of the site. The approach remained based on principles and techniques derived from motivational interviewing and cognitive-behavioural therapies.
The previous version had been structured as six consecutive modules to be accessed weekly. An analysis of data provided by the first 10,000 people who registered at the site after piloting ended in September 2003 revealed that most were in their 30s and 40s, half were women, nearly two-thirds were married or living with a partner, just 4% were unemployed, and most reported occupations from higher socioeconomic strata. As an earlier study commented, site users were predominantly middle class, middle aged, white and European. Six in 10 either did not start the programme, or completed just the first week. About 17% completed the six weeks. Of these, 57% returned an outcome questionnaire. Compared to their pre-programme status, on average they were now at substantially lower risk, and functioning better and living much improved lives. The sample had been recruited over about 27 months, a registration rate of about 4500 a year. By way of comparison, in England during 2008/09, around 100,000 adults were treated for their alcohol problems at conventional services. User profile and site usage had been similar during the earlier pilot phase. Results from surveys sent to pilot programme completers indicated that three quarters had never previously sought help for their drinking.

Given its low cost per user, this type of intervention seems to have a worthwhile place in a public health approach to reducing alcohol-related problems.
Though only a minority of site visitors may sign up for web-based alcohol programmes, nevertheless the numbers engaged can be very large, and the risk-reductions seem of the order typical in studies of brief advice to drinkers identified in health care settings. In these settings screening programmes typically identify people who are not actually seeking help for drinking problems – ‘pushing’ them towards intervention and change – while web sites ‘pull’ in people already curious or concerned about their drinking. As such these two gateways can play complementary roles in improving public health and offering change opportunities to people who would not present to alcohol treatment services. However, in Britain and elsewhere, both tactics reach only small fractions of the population who drinking excessively, leaving the bulk of the public health work to be done by interventions which drinkers generally cannot avoid and do not have seek out, such as price increases and availability restrictions.
With its combination of a randomised trial and a ‘real-world’ test, the featured research programme has gone further than any other in establishing the beneficial impacts of web-based alcohol interventions. However, largely because many site users do not complete research surveys, it remains impossible to be sure that the results seen in such studies will be replicated across the entire usership of the sites. Details below.
Strengths and limitations of the featured study
The featured study’s combination of a randomised trial with all its methodological safeguards, and a ‘real-world’ trial approximating normal conditions, affords what seems to be the best indication to date of the contribution web-based self-help interventions could make to reducing heavy drinking and associated health risks. However, its twin pillars are weakened by the fact that many people either did not join the studies or did not supply follow-up data; those who did may not have been typical of all the people who might access such sites. In the randomised trial, 40% of the baseline sample did not complete the six-month follow-up survey, and in the featured study, nearly 60%. Though on the measures taken by the study the respondents generally seemed typical of the baseline sample, clearly something was sufficiently different to cause them to respond while the others did not. In both studies this problem was catered for by assuming that non-responders were also non-changers. Though this almost certainly underestimated the impact of the intervention, still in both there remained significant and worthwhile improvements.
What could not be catered for in either study was the degree to which people who join such studies differ from the much greater number who would use the web sites, but decline participation in research. This problem was especially apparent in the featured study, in which it seems that around 6% of site visitors signed up for the self-help programme. Of these, perhaps a third or slightly more of the people who signed up for the programme during the relevant period also agreed to participate in the research. In some important ways (including amount drunk and motivation to change) they seemed similar to the bulk of programme sign-ups, though the researchers suspect they were more likely to have engaged with the programme.
Opening more doors to change for more people
A review of computer-based alcohol services for the general public has rehearsed the advantages: immediate, convenient access for people (the majority in developed nations) connected to the internet; consequently able to capitalise on what may be fleeting resolve; anonymous services sidestep the embarrassment or stigma which might deter help-seeking; such services are available to people unwilling or less able to talk about their problems to a stranger; generally they are free and entail no travel costs or lost income due to time off work; very low operating cost per user if widely accessed; easily updated. In consumption terms, the drinking problems of web site users are comparable to those of drinkers who seek treatment, yet few have received professional help, perhaps partly because their higher socioeconomic status and greater resources have enabled them to restrict the consequential damage. People who actually engage with web-based assessments of their drinking problems have more severe problems than those who just visit and leave. Including the randomised trial which paved the way for the featured study, the review found eight studies which evaluated the effectiveness of computer-based interventions for the general public. In all but one the users significantly improved on at least one of the alcohol-related measures recorded by the studies.
A particular role for alcohol self-help sites may be to offer an easy, quick and accessible way to for drinkers to actualise their desire to tackle their problems, especially when that desire is allied with the resources to implement and sustain improvements without face-to-face or comprehensive assistance. After conducting the Project MATCH trial, some of the world’s leading alcohol treatment researchers argued that “access to treatment may be as important as the type of treatment available”. The implication is that in cultures which accept ‘treatment’ as a route to resolving unhealthy and/or undesirable drinking, having convincing-looking and accessible ‘treatment doors’ to go through may be more important than what lies behind those doors, as long as this fulfils the expectations of the client or patient. This is likely to be especially the case for people who retain a stake in conventional society in the form of marriages, jobs, families, and a reputation to lose. These populations – the kind the featured study suggests are attracted to self-help alcohol therapy web sites – have more of the ‘recovery capital’ resources needed to themselves do most of the work in curbing their drinking.
The British Down Your Drink site
The best known British alcohol self-help web site is the Down Your Drink site run by a team based at University College London, an initiative originally funded by the Alcohol Education and Research Council and now by the Medical Research Council’s National Prevention Research Initiative. In 2007 this was revised to offer set programmes from a one-hour brief intervention to several weeks, but also to generally give the user greater control over the use they made of the site. The approach remained based on principles and techniques derived from motivational interviewing and cognitive-behavioural therapies.
The previous version had been structured as six consecutive modules to be accessed weekly. An analysis of data provided by the first 10,000 people who registered at the site after piloting ended in September 2003 revealed that most were in their 30s and 40s, half were women, nearly two-thirds were married or living with a partner, just 4% were unemployed, and most reported occupations from higher socioeconomic strata. As an earlier study commented, site users were predominantly middle class, middle aged, white and European. Six in 10 either did not start the programme, or completed just the first week. About 17% completed the six weeks. Of these, 57% returned an outcome questionnaire. Compared to their pre-programme status, on average they were now at substantially lower risk, and functioning better and living much improved lives. The sample had been recruited over about 27 months, a registration rate of about 4500 a year. By way of comparison, in England during 2008/09, around 100,000 adults were treated for their alcohol problems at conventional services. User profile and site usage had been similar during the earlier pilot phase. Results from surveys sent to pilot programme completers indicated that three quarters had never previously sought help for their drinking.

Levels of the serotonin transporter are low in the brains of users of ecstasy, according to a US National Institute of Drug Abuse-funded study by Toronto’s Centre for Addiction and Mental Health (CAMH) and The Hospital for Sick Children (SickKids) published today in the journal Brain.
Ecstasy (MDMA) is a stimulant drug widely used recreationally that is also being tested in clinical trials for the treatment of post-traumatic stress disorder.
Led by Dr. Stephen Kish at CAMH, this study provides confirmation of a previous finding from Johns Hopkins University that levels of the serotonin transporter (SERT) are low in cerebral cortex of chronic ecstasy users. The subjects were “typical” ecstasy users who used about two tablets of the drug twice a month.
SERT is a protein responsible for regulating levels of serotonin, a neurotransmitter important for mood and impulse control. Ecstasy interacts with SERT to cause the release of serotonin, an action that probably explains some of the behavioral effects of the drug such as increased sociability.
Scientists have long suspected that ecstasy might harm brain cells that use serotonin, but 12 years of brain scan studies have produced contradictory results, even within the same laboratory.
The CAMH study used a large subject size (49 drug users, 50 control subjects), confirmed by hair analysis that ecstasy users actually used the drug, and used an imaging probe that could measure SERT throughout the brain.
“We were surprised to discover that SERT was decreased only in the cerebral cortex and not throughout the brain, perhaps because serotonin nerves to the cortex are longer and more susceptible to changes. This finding is almost identical to newer data from Johns Hopkins and is the first time that one laboratory has actually been able to replicate results of another independent laboratory in a SERT study of ecstasy users.” said Dr. Kish.
Drug hair analysis indicated that many ecstasy users, probably unknowingly, also used methamphetamine, which might itself damage serotonin cells; however, low SERT was found both in ecstasy users who used and who did not use methamphetamine. Dr. Jason Lerch at SickKids showed that those ecstasy users who also used methamphetamine had a slightly thinner cerebral cortex.
Does low SERT equal “structural brain damage”? “Not necessarily” said co-author Dr. Isabelle Boileau of CAMH. “There is no way to prove whether low SERT is explained by physical loss of the entire serotonin nerve cell, or by a loss of SERT protein within an intact nerve cell.”
Dr. Kish suggests that low SERT might explain why many ecstasy users need to keep increasing the dose to experience the same effects, since SERT is necessary for the action of ecstasy. “Most of the ecstasy users of our study complained that the first dose is always the best, but then the effects begin to decline and higher doses are needed. The need for higher doses, possibly caused by low SERT, could well increase the risk of harm caused by this stimulant drug,” said Dr. Kish.

Researchers have discovered that ¬consuming a very high amount of alcohol in a short time can cause irreversible damage. In the long run youngsters risk becoming absent-minded and forgetful.
Previous research found that high levels of alcohol act as a poison and prevent the brain working properly. Now scientists say that excess alcohol can actually destroy grey matter called the hippocampus, which stores and recalls events and forms mental images, known as spatial reasoning.
A US team gave alcohol for one hour a day to teenage macaque monkeys, who drank until they were drunk. Their brains produced fewer cells and suffered more neural degeneration than a control group. Last year, a survey of 35 countries found the UK had the third highest number of 15 and 16-year-olds with an alcohol problem. Girls were worse than boys.
Don Shenker, chief executive of Alcohol Concern, said the Government needed “to force the drinks industry to ensure consumers are aware of the dangers”.

“This report summarises the key findings from a report exploring public attitudes towards illegal drugs and drug misuse in Scotland, based on data from the 2009 Scottish Social Attitudes survey. It focuses in particular on attitudes towards opiate misuse, and on views of potential policy responses to this. However, it also places such attitudes in the context of wider views and experiences of illegal drugs.”

Main Findings

■ Support for legalising cannabis – which increased in Scotland (as in the rest of the UK) in the late 1990s – has fallen considerably in more recent years, from 37% in 2001 to 24% in 2009. Attitudes towards prosecution for possession of cannabis for personal use also hardened between 2001 and 2009.
■ Most people said taking cocaine occasionally is wrong – 76% rated it as 4 or 5 on a scale where 5 meant ‘very seriously wrong’.
■ 45% of people agreed that ‘Most people who end up addicted to heroin have only themselves to blame’, while just 27% disagreed.
■ Around half (53%) disagreed that ‘most heroin users come from difficult backgrounds’ (29% agreed).
■ Among those in paid employment, around half (47%) said they would be ‘very’ or ‘fairly comfortable’ working alongside someone they knew had used heroin in the past, while around 1 in 5 would be uncomfortable.
■ Just a quarter (26%) said they would be comfortable with someone who was receiving help to stop using heroin moving near to them, while half (49%) would be uncomfortable.
■ There was no public consensus on what should be the top government priority for tackling heroin use in Scotland – 32% chose ‘tougher penalties for those who take heroin’, 32% ‘more help for people who want to stop using heroin’ and 28% ‘more education about drugs’.
■ Just 16% agreed that people who possess heroin for personal use should not be prosecuted (compared with 34% for cannabis).
■ Public support for providing clean needles to injecting drug users fell from 62% in 2001 to 50% in 2009.
■ Opinion on educating young people about safer drug use was split – 44% agreed that young people should be given information about how to use drugs more safely, but 40% disagreed.
■ Four out of five (80%) agreed that ‘the only real way of helping drug addicts is to get them to stop using drugs altogether’. However, 29% agreed that ‘most heroin users can never stop using drugs completely’, while 27% said they neither agreed nor disagreed or did not know.
■ 63% disagreed that ‘Someone who has been a heroin addict can never make a good parent, even if their drug problems are in the past’.
■ Around two thirds (64%) said that young children of heroin users should be placed into temporary foster care until the parents stop taking heroin. A further 1 in 5 believed the child should stay at home while the family receives help from social workers and just 8% said the child should be permanently adopted by another family.

Abstract
California data on drivers involved in passenger vehicle fatal crashes using Marijuana were analyzed to determine the impact on traffic safety and to provide information on the possible impact of an initiative, the Tax and Regulate Cannabis Initiative or “TC2010” which is on the California ballot in November 2010 to reform and partially legalize Marijuana.

A total of 1240 persons were killed in the last five years in fatal motor vehicle crashes involving Marijuana. 230 were killed in 2008. Use has increase steadily in the last ten years and is now at 5.5% in fatal passenger vehicle crashes. The use in single vehicle fatal crashes where most drivers are tested shows an involvement rate of 8.3%.

The largest increases occurred in the 5 years following the legalization of Medical Marijuana in January 2004. For the five years following legalization there were 1240 fatalities in fatal crashes, compared to the 631 fatalities for the five years prior, for an increase of almost 100%. In 2008 there were 8 counties where more than 16% of the drivers in fatal crashes
tested positive for Marijuana. Five of the 8 counties had rates over 20%

Based on this experience, a use rate of 16% to 20% is very likely. A rate increase to only 16%, would result in 670 fatalities, and at 20% we would have about 840 fatalities annually. The 20% level would be more than triple the present level of 230 fatalities in 2008. At these levels, Marijuana would rival alcohol at 17.9%, as the top cause of traffic fatalities.

If “TC2010” passes, tax income on Marijuana is estimated at $1.4 billion annually compared to an estimated $4 billion or more economic loss from Marijuana related fatal crashes.
Over 80% of the Marijuana drivers are male, with a median age of 25. In addition, about half (48%) of the drivers using Marijuana also were legally intoxicated. About 75% of the drivers that used Marijuana did not use any other drug. About 1.2 fatalities were reported for each Marijuana involved driver.

Historian looks at resistance to the “NIDA paradigm.”

The history of addiction as a brain disease “looks a lot like the history of atoms or germs, insofar as these were older and controversial ideas for which scientific confirmation later became available,” writes historian David Courtwright, author of Forces of Habit: Drugs and the Making of the Modern World.

In a recent issue of the social science journal BioSocieties, Courtwright surveys the history of the disease paradigm of drug addiction, and, in doing so, brings into focus several key dilemmas related to what former National Institute on Drug Abuse (NIDA) director Alan Leshner once characterized as the “quintessential biobehavioral disorder.”

The scientific evidence available to us at present largely supports a statement like Leshner’s. Researchers have documented long-term changes in brain structure and function due to drug abuse, and neuroimaging technologies have resulted in maps of the abnormal neuronal activity addicts exhibit. Courtwright cites the discovery of the endogenous opioid system, the mapping of receptor pathways, and the growing understanding of the mesolimbic dopamine reward pathway as evidence of clinical confirmation of theories about addictive disease that has been floating around in one form or another for many years.

Why then, Courtwright asks, does the medical profession largely stay clear of issues having to do with our law enforcement-driven drug war? Why are clinical professionals not on the front lines of revolt over this issue? “If addiction was beyond the individual’s control, then criminal punishment was as inappropriate as jailing a schizophrenic who wandered into an emergency room,” the author writes.

The most obvious reason for this conundrum, says Courtwright, is that “the brain disease model has so far failed to yield much practical therapeutic value.” The disease paradigm has not greatly increased the amount of “actionable etiology” available to medical and public health practitioners. “Clinicians have acquired some drugs, such as Wellbutrin and Chantix for smokers, Campral for alcoholics or buprenorphine for heroin addicts, but no magic bullets.” Physicians and health workers are “stuck in therapeutic limbo,” Courtwright believes. “The drug-abuse field is characterized by, at best, incomplete and contested medicalization.”

Moreover, unlike the current situation in the case of, say, diabetes or schizophrenia, “at least four important groups continue to wrestle for control of the addiction field.” (Medical personnel, police, social scientists, and political officials.) Social scientists, in particular, are frequently skeptical about the NIDA disease paradigm “as part of a broader post-World War II pattern of resistance against biological explanations of behavior, genetic research and the neo-Darwinian renaissance.”

Social scientists and neuroscientists “still live in their own gated academic communities,” Courtwright alleges. “There is a lot more at stake in the brain disease debate than our understanding of addiction.”

However, these problems do not mean that valuable findings in one area–addictive disease theory–cannot produce innovations in other research fields as well. In fact, such spinoffs happen all the time. Courtwright points to advancements in our understanding of evolution: “Michael Kuhar has argued that, because the brain co-evolved with neurotransmitters, it can usually manage its internal chemistry quite well. But it did not co-evolve with drugs, understood as recently introduced and wholly exogenous super-neurotransmitters that can override the brain’s control mechanisms.”

The author also cites spinoffs in economic studies: “The permanent alteration of neurons and the development of addiction in some, but not all, users also helped explain the commercial and tax appeal of drugs, insofar as they were nondurable goods with relatively inflexible demand curves. Even non-addicted users tended to consume more over time, because of tolerance.”

In the end, it is just possible to contemplate some sort of fusion, or meeting of the minds, over the disease model. As Courtwright speculates, “it may turn out that the tension between the personality and brain disease models is more apparent than real.” He cites as evidence such connections as the fit between impulsive, thrill-seeking behavior and an associated paucity of dopamine D2 and D3 receptors in the midbrain region. The result? Such people “have less inhibition of dopamine, and experience more reward when stimulated by risky behavior.” A nice fit. And the number of nice fits between social science and brain science continues to accumulate.

“If the brain disease model ever yields a pharmacotherapy that curbs craving, or a vaccine that blocks drug euphoria, as some researchers hope,” Courtwright says, “we should expect the rapid medicalization of the field. Under those dramatically cost-effective circumstances, politicians and police would be more willing to surrender authority to physicians.”

I-dosing on “digital drugs” is becoming an alarming new trend amongst teens. Web sites are luring kids with free downloads of “digital drugs,” which are audio files designed to induce drug-like effects. Videos of teenagers trying the digital drugs are all over YouTube
Web sites are luring kids with free downloads of “digital drugs,” which are audio files designed to induce drug-like effects. The sites claim it is a safe and legal way to get high, but parents fear it could lead to illegal drug use.
Videos of teenagers trying digital drugs are all over YouTube, leaving parents, educators and law enforcement officials with the Oklahoma Bureau of Narcotics and Dangerous Drugs concerned.
“Kids are going to flock to these sites just to see what it is about and it can lead them to other places,” said OBNDD spokesperson Mark Woodward.
The digital drugs use binaural or two-toned technology to alter your brainwaves and mental state.
“Well it’s just scary, definitely scary. Just one more thing to look out for,” said parent Kelly Johnson.
Recently Mustang Public Schools sent out a letter warning parents about the new trend after several high school students reported having physiological effects after trying one of these digital downloads. Students and graduates are still talking about it.
“I heard it was like some weird demons and stuff through an iPod and he was like freaking out,” said Mustang High School student Meghan Edwards.
“People do need to be concerned about it. It’s not just something that should be overlooked,” said Shelbi Reed, Mustang High School graduate.
“We had never come across anything like this and anything that is going to cause these physiological effects in a student, that causes us concern,” said Shannon Rigsby, Mustang Public Schools Communication Officer.
Mustang schools are doing what they can to put a stop to it, including cracking down on the use of cell phone and other technology while on campus.
The Oklahoma Bureau of Narcotics said parental awareness is key to preventing future problems, since I-dosing could indicate a willingness to experiment with drugs.
“So that’s why we want parents to be aware of what sites their kids are visiting and not just dismiss this as something harmless on the computer,” Woodward said. “If you want to reach these kids, save these kids and keep these kids safe, parents have to be aware. They’ve got to take action.”
Another concern the OBN has is that many of these I-dosing sites lure visitors to actual drug and drug paraphernalia sites.

The brain’s nucleus accumbens (NAC) is a core region of the mesocorticolimbic dopaminergic system and is interconnected with the ventral tegmental area (VTA) and the prefrontal cortex. The mesocorticolimbic system is thought to be central to the reinforcing effects of many drugs and plays an important role in addiction. A new study has found that alcohol abuse elevated the expression of a distinct set of genes in the NAC and VTA, while nicotine blunted this effect in the VTA.

Results will be published in the July 2010 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.

“In spite of their differences in pharmacology, alcohol and tobacco consumption are often intimately linked,” said Traute Flatscher-Bader, a postdoctoral research fellow at The University of Queensland and corresponding author for the study. “Nonetheless, the molecular mechanisms that underlie alcohol and nicotine abuse, and particularly their co-abuse, are still incompletely understood.”

“One thing that researchers have encountered is that it is often difficult to find ‘pure’ alcoholics, that is, alcoholics that only abuse alcohol and nothing else,” agreed Simon Worrall, director of postgraduate coursework programs in molecular biology at The University of Queensland. “Many alcoholics are poly-drug abusers, with the most common other drug being nicotine. Thus, many studies which have studied the effects of alcohol on the brain and other organs have been compromised because they have not taken account of the effects of nicotine addiction which is often superimposed on the effects of alcohol addiction.”

In the first part of the current study, Flatscher-Bader and her colleagues used DNA microarray technique to study the expression of many thousands of genes in the brains of non-smoking and smoking alcoholics and non-drinking smokers.

“We examined the impact of alcoholism and smoking on gene expression in the NAC in 20 chronic alcohol abusers and controls with and without recent smoking history,” said Flatscher-Bader. “The results revealed that in this brain region, the abuse of alcohol and nicotine had distinct effects on the expression of genes. In addition, altered expression of a number of genes was associated with both alcohol and nicotine abuse. Within the latter group was a set of genes which play a crucial role in a molecular pathway regulating cell structure.”

The researchers then went on to investigate in more detail the altered expression of six selected genes within the pathway regulating cell structure in two brain regions, using 30 cases comprised again of smoking and non-smoking controls and alcohol abusers. For this part of the study they used the method called “real time polymerase chain reaction.”

“This expanded investigation revealed that one of the genes, called RHOA, was elevated by alcohol abuse and its highest expression was evident in the smoking alcoholics in both brain regions,” said Flatscher-Bader. “The RHOA gene had previously been implicated in the initiation of tobacco smoking. In the NAC, the expression of a further four of the six selected genes was increased by alcohol abuse. Interestingly, the highest expression for each of the genes in the NAC was in the smoking alcoholics. In the other brain region called the VTA, alcohol abuse had a similar effect and elevated the expression of all six selected genes. In contrast to the NAC, however, concurrent smoking dampened the induction of five of these alcohol-sensitive genes in the VTA.”

“Many studies have analyzed the changes in gene expression in this brain system to try to untangle the molecular pathology of alcohol addiction,” said Worrall, “but this is amongst the first to take into account the effect of co-administration of nicotine with alcohol.

Flatscher-Bader stressed that there are several cell types in the brain and there are several steps between gene expression and impact on cell structure and function. “It has to be emphasized that our study is important as a first step in identifying molecular pathways underlying the effects of alcohol abuse and smoking and their co-joint abuse on the human NAC and VTA, “she said. “It now needs to be tested if our findings are, indeed, associated with changes to neuronal structure and function.”

“A better understanding of the molecular basis of withdrawal may help in the development of new treatments to ameliorate the symptoms,” added Dr Worrall. “Not many previous studies took into account the potential effects of nicotine addiction that may be superimposed on top of those from alcohol, so these results may help clinicians better use present therapy/drugs to treat patients abusing both alcohol and/or nicotine and may also lead to the development of new drugs.”

Recent research has clarified a number of important questions concerning adverse effects of cannabis on health.

A causal role of acute cannabis intoxication in motor vehicle and other accidents has now been shown by the presence of measurable levels of Δ9-tetrahydrocannabinol (THC) in the blood of injured drivers in the absence of alcohol or other drugs, by surveys of driving under the influence of cannabis, and by significantly higher accident culpability risk of drivers using cannabis.

Chronic inflammatory and precancerous changes in the airways have been demonstrated in cannabis smokers, and the most recent case-control study shows an increased risk of airways cancer that is proportional to the amount of cannabis use.

Several different studies indicate that the epidemiological link between cannabis use and schizophrenia probably represents a causal role of cannabis in precipitating the onset or relapse of schizophrenia.

A weaker but significant link between cannabis and depression has been found in various cohort studies, but the nature of the link is not yet clear. A large body of evidence now demonstrates that cannabis dependence, both behavioral and physical, does occur in about 7–10% of regular users, and that early onset of use, and especially of weekly or daily use, is a strong predictor of future dependence.

Cognitive impairments of various types are readily demonstrable during acute cannabis intoxication, but there is no suitable evidence yet available to permit a decision as to whether long-lasting or permanent functional losses can result from chronic heavy use in adults. However, a small but growing body of evidence indicates subtle but apparently permanent effects on memory, information processing, and executive functions, in the offspring of women who used cannabis during pregnancy. In total, the evidence indicates that regular heavy use of cannabis carries significant risks for the individual user and for the health care system.
