Aims: In most countries, cannabis use rates are highest among young people. Efforts invested in cannabis prevention programmes have had limited success. In part, this may be attributed to a dearth of meaningful discussion in classroom settings on the topic and scarcity of credible resources. Although young people want opportunities to engage in…

Although such policies are intended to affect individual choices, they by definition operate on a national level and cannot be evaluated solely on the basis of individual-level differences. This study aims to evaluate the impact of country-level…
