Substance use prevention targeting children and adolescents is a science that relies on evidence-based interventions to address the complex factors contributing to substance use disorders – Photo by Ernest Brillo on Unsplash
On Tuesday 12 May, the first session in a series of debates organized by G2H2 was opened. Entitled ‘People, power and policies in global health: perspectives from civil society’, the series was organized in the run-up to the 78th World Health Assembly, held from 19 to 27 May.
Co-hosted by Dianova and the Geneva Global Health Hub (G2H2) , the session ‘Growing up safe: public health approaches to drug use prevention and treatment for children and adolescents’ brought together high-level participants, including Anja Busse (WHO) and Wadih Maalouf, (UNODC).
G2H2 is a network of civil society organisations based in Geneva that promotes information exchange and joint political action on global health issues – Dianova International is a member of G2H2.
The main objective of the session, as outlined by Gisela Hansen (moderator, Dianova International), was to reconnect drug policies with public health, focusing on the prevention and treatment of substance use among children and adolescents. The aim was to promote models centred on health and human rights, especially in vulnerable or disadvantaged contexts around the world.

Anja Busse (WHO)
Head of the Unit on Drugs, Alcohol and Addictive Behaviours at the WHO. Anja has been involved in this field at the global level since 2005 and has been supporting science-based strategies for the treatment and care of drug dependence.
Anja took the floor and began by reminding the WHO’s commitment to promoting global health, particularly among the most vulnerable. The WHO Constitution (1946) emphasizes the importance of healthy child development: “Healthy development of the child is of basic importance, the ability to live harmoniously in a changing total environment is essential to such development.”
“A public health response to substance use prevention and treatment means reaching the highest number of people with the most effective, least costly, and least invasive strategy or intervention”
This involves creating environments in which children and adolescents can grow up healthy and safe, and where it is easier for them to avoid alcohol, tobacco and drugs. The burden of responsibility should primarily be placed on the system and on all of us rather than on the individual.

Globally, 22% of young people aged 15 to 19 consume alcohol, with significant regional differences demonstrating the fundamental role of our environment
UNODC data also reveal that, in 2021, around 5.3% of 15–16-year-olds had used cannabis in the previous year, and that, in most countries and regions, cannabis use is more prevalent among young people than in the general population.

Anja highlighted that the UNODC and the WHO have published several documents on the health and development of children and adolescents, as well as international standards on drug use prevention. These include strategies targeting the population as a whole, as well as those used in schools, the health system, the workplace, the community, and finally, families. She emphasised one of the basic principles of prevention: ‘The earlier we act, the better’, although it is never too late to implement interventions.
Science based strategies targeting the general population have the widest impact, but they must also consider implementing interventions for the most at-risk groups.

According to Anja, the most effective strategies target multiple and multi-level vulnerabilities rather than limiting themselves to narrow interventions in single settings. Finally, Anja emphasised the need for well-conducted planning involving many stakeholders and for an effective social and health system providing accessible mental healthcare services at all levels, which is not the case everywhere.
While it is acceptable for a government to restrict or regulate the availability, distribution and production of drugs, it is important to avoid the unnecessary punishment of people who use drugs.
After reviewing various organizational prevention methods and their effectiveness, Anja also highlighted interventions that research has found to be ineffective or of questionable or unproven effectiveness. These include media awareness campaigns (not effective); use of social media and influencers (effectiveness unknown); information sessions on the consequences or harms of drugs (not effective); sports and other leisure activities (lack of evidence, controversies) strategies targeting children/youth particularly at risk (lack of evidence) and drug testing in schools (no evidence).

Oriol Esculies – Proyecto Hombre (Spain)
Oriol is a psychologist with over thirty years’ experience of helping people with addiction problems. He is the International Commissioner of the Proyecto Hombre association and coordinator of the Oviedo Declaration.
The impact of drugs, including tobacco and other legal substances, is enormous. This is not only an issue of security, economics or the law, but also a health issue affecting millions of people, including children and adolescents, in all aspects of their health: physical, emotional, intellectual and social.
We must invest in health now, while our children are healthy; otherwise, the future problem of substance use will be greater, not only for them, but for society as a whole – this is the paradox of prevention.

This also presents a significant challenge to decision-makers and governments, as it necessitates planning and governance with a long-term vision. Launched last year, the Oviedo Initiative is a declaration comprising ten proposals in line with international standards on prevention. It is also a global mobilisation to incorporate prevention into drug policies once and for all. It is an inclusive, collective campaign that is already supported by over 3,000 institutions and several observers, including the UNODC.

The main strength of this initiative, which builds bridges between local and global levels, lies in the voluntary work of 174 focal points within countries. At Dianova International, we are honoured to contribute to this initiative as the focal point for Switzerland.
We hope that the resolution on prevention recently adopted by the CND in Vienna last March will mark a turning point towards the accelerated implementation of effective and forward-looking drug prevention policies.
Shrooq Mansour Ali, Psychiatric Care Developmental Foundation (Yemen)
As a public health expert and the Yemen focal point for the Oviedo Initiative, Shrooq works for the Yemeni NGO, the Psychiatric Care Developmental Foundation, providing mental health and psychological support services to vulnerable young people.
She points out that, after ten years of conflict, Yemen is facing one of the world’s worst humanitarian crises, exacerbated by ongoing violence, the consequences of climate change and the collapse of the economy, institutions and services. According to the 2024 Humanitarian Needs Assessment, approximately half of Yemen’s population, or more than 18 million people, require humanitarian assistance.
Research has shown that populations affected by armed conflict are at a higher risk of using drugs as a coping mechanism in response to such dramatic situations.
Furthermore, factors such as prolonged psychological trauma, disrupted education, unemployment and chronic poverty in Yemen further increase the risks. Despite this, mental health and substance use issues remain highly neglected. Therefore, ensuring adequate care for substance use issues in humanitarian contexts is a priority.
As the focal point for the Oviedo Declaration in Yemen, Shrook and her colleagues face significant challenges in advancing the initiative within government structures due to the many divisions between the government recognised by international institutions in the south and the de facto authorities in the north. This means that all activities must be coordinated with different entities, which is made more difficult by the sensitive nature of the issue.
Yemen lacks reliable data on substance use. As one of the Oviedo Declaration’s recommendations highlights, there is a need to focus on evidence-based strategies grounded in the collection and evaluation of data. This data would serve as a basis for implementing prevention programmes and national policies in this area.
Problems associated with substance use exist in Yemen and can no longer be ignored or denied.
Cristina von Sperling Afridi, Karim Khan Afridi Welfare Foundation (KKAWF), Pakistan
Following the tragic loss of her son, Karim, in 2015, Cristina established the Karim Khan Afridi Welfare Foundation (KKAWF) to support young people and raise awareness of addiction. The foundation’s work is based on five pillars: drug awareness, sport, the environment, art and culture, and civic engagement.
Currently in Pakistan And across the region Drug use prevention strategies are significantly underrepresented In public policies agendas. The Oviedo declaration launched in 2024 represents a timely and powerful call to action urging nations to prioritize prevention in the drug policies For Pakistan this framework offers a critical opportunity to redirect focus towards long-term sustainable solutions.
Cristina emphasised the urgency of the situation: Pakistan lies at the heart of the Golden Crescent, one of the world’s most notorious drug producing region. Of all the countries in the region, Pakistan is the most affected by the drug menace. It harbors the largest heroin consuming population in the region, a crisis now compounded by the rise of crystal meth.
Drug use among young people poses a particular risk to democracy in Pakistan, a country with a population of around 250 million, 154 million of whom are under the age of 30. This massive young population is the country’s greatest asset and potential, but also its greatest vulnerability.
The growing threat of drug use among young people poses considerable social, health, and economic challenges for the nation. The KKAWF Foundation plays an active role in preventing drug use. It raises awareness among policymakers, civil society and other stakeholders of the importance of prevention.
Prevention must become the central pillar of national drug policies, but this requires essential resources, coordination and commitment — and urgently so!
The KKAWF develops numerous partnerships in its advocacy work for prevention. Here, the Foundation’s president, Cristina Von Sperling Afridi (right), with a representative of the Green Crescent Federation – Photo: KKAWF, all rights reserved
One of the Foundation’s main areas of focus is fostering collaboration between the government, civil society organisations, and the private sector, as only a unified, strategic approach can effectively address this public health crisis. It is also crucial to integrate drug education into school curricula at secondary and higher education levels.
The KKAWF advocates an evidence-based, stigma-free approach that promotes emotional intelligence, resilience, and critical thinking.
Cristina believes that prevention must become a way of life, not just a programme. She believes that only by cultivating a culture of prevention will it be possible to protect future generations.
Rajesh Kumar, Society for the Promotion of Youth and Masses (SPYM), India
Rajesh is the executive director of SPYM, an NGO that has worked in the field of addiction for over 40 years, receiving several national awards for its work with marginalised communities. SPYM has consultative status with ECOSOC, and Dr Kumar has served on numerous government and international bodies.
India’s proximity to the Golden Crescent and Golden Triangle has made the country a destination for large quantities of drugs. Substance use is therefore on the rise, particularly among children. In response to this serious violation of children’s rights, SPYM began working with children suffering from addiction in 2010.
In India, approximately 4 million children use opiates, 2.6 million inhale drugs, and 2 million use cannabis. Even with a population of over 1.4 billion, these figures represent a huge problem, particularly given that only 1% of affected children seek help.
While it is estimated that 99.9% of children do not use drugs, it is essential to invest in treatment and scientifically validated prevention strategies based on collaboration with families, communities and schools to ensure they stay on this path. These groups have a duty to ensure that substance use prevention and mental health are part of their regular activities, which is why SPYM has developed the Navchetna programme under the auspices of the Ministry of Social Justice and Empowerment.

The Navchetna school programme is designed with different modules tailored to students according to their age. It is run by trained teachers under the supervision of the Ministry of Education.

Once their training is complete, the ‘master trainers’ must in turn train up to 100 teachers within two years, with the ultimate goal of training one million teachers, although so far, only 100,000 have been trained. The programme also uses videos, which are currently available in English and Hindi and will soon be available in 12 regional languages.
SPYM also develops numerous programmes and activities to help vulnerable people, particularly children and teenagers. These include a community-based early intervention programme run by peers in nearly 300 districts in the country most affected by drug use, residential treatment centres for various populations including children and adolescents in conflict with the law, activities focused on life skills and rehabilitation, and advocacy activities.
SPYM and KKAWF are both associate members of Dianova International.
Cressida de Witte – World Federation Against Drugs (WFAD, Sweden)
Cressida is the project coordinator and communications manager for the WFAD. She leads projects for this organisation in various countries, including the Democratic Republic of Congo, Kenya, India, and Georgia. She is also a member of the WFAD committees on gender and youth.
The continuum of care includes a wide range of interventions, from health promotion to recovery and follow-up, including various prevention strategies and different phases or modalities of treatment.

Although prevention programmes for young people generally target school-age children, adolescents and young adults due to the high risk of experimenting with substances, research has shown that prevention efforts should start even earlier.
The early years of a child’s life are a critical period for brain development. This is when the foundations of decision-making, impulse control and resilience are laid. As younger children learn to manage their emotions, resolve conflicts and set goals, they develop skills that will inform healthier choices in adolescence and adulthood.
However, prevention is not solely the responsibility of the child; it also depends on their environment, which is why action must be taken at all levels, from the macro to the micro, and from family dynamics to community support.
The WFAD is a multilateral community with ECOSOC consultative status, composed of over 470 NGOs in 73 countries. The organisation’s three pillars are capacity building through webinars, training courses and forums; advocacy at national, regional and international levels to strengthen prevention, treatment and recovery; and project development, particularly international projects. One such project is a youth project in the Democratic Republic of Congo: Sober Youth and Healthy Communities: Transforming Violent Youth in Kinshasa. Learn more about the project.
Within the framework of these advocacy efforts, the organisation launched the ‘Global Youth Declaration on Prevention, Treatment and Recovery’. Presented at the 68th session of the CND in March 2025, the declaration is based on six recommendations aimed at ‘ensuring access to prevention, treatment, rehabilitation and recovery services that are youth-friendly and respectful of their rights, in order to ensure a healthy, safe and drug-free future for all young people worldwide’. The declaration is available in seven languages.
Rebecca Haines-Saah – University of Calgary (Canada)
Rebecca is a public health sociologist and associate professor at the University of Calgary. Her research interests include youth drug use, harm reduction approaches, and drug policy reform.
As a teenager, she was cast in a popular Canadian television programme in which her character experimented with substance use. This, in some way, launched her career and her commitment to supporting young people she said.
Rebecca believes that we need to radically rethink drug prevention for young people. Unfortunately, in North America as elsewhere, prevention has long been based on values rather than scientifically validated evidence of what works and what doesn’t. Past prevention campaigns, such as Nancy Reagan’s ‘Just Say No’ motto, were never evidence-based or evaluated.
“Prevention has been based on values rather than evidence for too long, which is why we need to radically rethink drug prevention for young people” – excerpt from presentation by Rebecca Haines-Saah
Even worse, an evaluation of the D.A.R.E. (Drug Abuse Resistance Education) programme – a series of lessons delivered by police officers in schools – showed that it was associated with a slight increase in substance use! It was hypothesised that the most marginalised young people reacted badly to the presence of police officers in the classroom. These campaigns primarily relied on stereotypes and stigmatisation of young people.
“In Canada, it has been highlighted that the most effective drug prevention programmes have very little to do with drugs”
If we want to improve prevention outcomes among young people, she stresses, we need to focus less on educating them about specific substances, and instead strive to promote community well-being, as well as individual and family resilience. That’s where we need to invest.
Scientific research indicates that effective strategies include psychosocial and developmental interventions that enhance conflict resolution and problem-solving abilities, social-emotional learning, and anything else that helps teenagers manage challenging situations with their peers and cope with trauma and community conflict. These strategies have demonstrated several positive long-term outcomes.
Rebecca also highlighted the implementation of a community-based prevention model in Calgary and other parts of the country. Planet Youth, the model implemented in Calgary and elsewhere, was developed based on the Icelandic prevention model: a participatory, evidence-based approach that has dramatically reduced substance use, particularly tobacco and alcohol.
Finally, Rebecca presented a slide on the ‘prevention pyramid’, particularly focusing on the first level: the more effort made to create equitable social and economic conditions, the better the results. She believes that this is a much more ambitious and difficult goal to achieve than simply setting up a programme or activity. However, it is on this point that our vision must be aligned.
The more effort that is made to create equitable social and economic conditions in prevention, the better the results.
In addition to prevention needs, Rebecca emphasised the urgent need to address young people’s harm reduction needs to prevent drug poisoning deaths. Drug poisoning is currently the leading cause of death among 10- to 18-year-olds in western Canada, ahead of cancer and car accidents, so this is a public health emergency.
Dr Wadih Maalouf – UNODC
Wadih is a public health professional who holds a PhD in mental health and drug epidemiology from the Johns Hopkins School of Public Health. With over 25 years’ experience, he is now the global coordinator of the addiction prevention programme at UNODC, and is one of the world’s leading prevention experts.
Wadih began by emphasising the importance and timeliness of this conversation because it is based on scientific evidence. A large number of standards have now been developed for prevention and treatment, thanks to collaboration between UNODC and WHO, and the science is available. He also noted that science is receiving greater recognition, not only from organisations working in the field, but also from civil society. This is evident in the 3,000 stakeholders who have rallied around the common agenda promoted by the Oviedo Declaration.
This recognition is also evident at government level, as demonstrated by the Commission on Narcotic Drugs’ resolutions, which call for early prevention to target different stages of development rather than drug use. These resolutions also call for multisectoral prevention, despite all the challenges posed by multilateralism.
There is now a desire to develop science-based, multisectoral prevention programmes for young people.
In his view, there is a real desire to prioritise science and prevention, particularly for young people, and to work across multiple sectors. With the right ingredients — science, political commitment, and action on the ground — it is possible to turn this knowledge into action.
As a people-centred approach, prevention must also focus on the environment and context in which people live, as well as their level of vulnerability. This systemic approach must aim to leave no one behind.
To achieve this, we must focus on different age groups, contexts of vulnerability and gender. This is an important consideration in the context of vulnerabilities, particularly for children, whose developmental trajectories may be affected in different ways.
The current generation of young people has the highest potential ever seen, which is why it is essential that they are meaningfully engaged in prevention efforts.
Young people are not only the beneficiaries of prevention; they must also be its agents because every child has the right to grow up healthy, and we have the means to make that happen.
