The incidence of these outcomes, however, is predicted by early onset and a high frequency and length of use that only apply to a minority of users. In a public health framework, cannabis use – especially in young populations – should be systematically monitored and high-risk patterns of use screened for in appropriate settings, e.g., schools and GP offices. Evidence-based primary and secondary prevention, treatment and enforcement need to be targeted at these high-risk patterns of use. Given the large cannabis user population, especially among young people, and the failure of the criminalization approach to discourage use, a public health framework for cannabis use is urgently needed in Canada.
