EPIDEMIOLOGY
In 2012, 43% of Canadians reported that they had used marijuana at some time in their lives, and 12% reported using it in the past year (Statistics Canada, 2013). Marijuana use was more common among males than females (Statistics Canada, 2013). People aged 18 to 24 had the highest prevalence of past-year marijuana use, and tended to use it more frequently than did people of other ages (Statistics Canada, 2013).
In Canada, as in many other countries, marijuana is the most commonly used illicit drug (Statistics Canada, 2013).
