Quality of Life and Cannabis Use: Results from Canadian Sample Survey Data 1

(Extracts from above paper shown below – log-on to source document to read whole paper).


Data from the 2013 Canadian Tobacco, Alcohol and Drugs Survey, and  two other surveys are used to determine the effects of cannabis use on self-reported physical and mental health. Daily or almost daily marijuana use is shown to be detrimental to both measures of health for some age groups but not all. The age group specific effects depend on gender. Males and females respond differently to cannabis use.

The health costs of regularly using cannabis are significant but they are much smaller than those associated with tobacco use. These costs are attributed to both the presence of delta9-tetrahydrocannabinol and the fact that smoking cannabis is itself a health hazard because of the toxic properties of the smoke ingested. Cannabis use is costlier to regular smokers and age of first use below the age of 15 or 20 and being a former user leads to reduced physical and mental capacities which are permanent.

These results strongly suggest that the legalization of marijuana be accompanied by educational programs, counselling services, and a delivery system, which minimizes juvenile and young adult usage. access to marijuana for all individuals under the age of 18.

Adolescents need to be encouraged not to use marijuana and strict government control over its production and distribution is needed to protect them. Price, THC content, and advertising also have to be regulated. At a more general level public policy should promote caution and awareness of the harmful consequences of marijuana use.
