    Description:

    The Canadian federal government legalized non-medical cannabis use by adults in October 2018. Ongoing monitoring of the effects of the change is needed because uncertainty remains about the impact of this legislation on cannabis use behaviours and whether the impact will affect some more than others. This study used data from Canadian Alcohol and Drugs Survey and its predecessor to examine longer-term historical rates of use during 2004 to 2017. Five iterations of National Cannabis Surveys (2018/2019) were used to examine current use (overall, daily/almost daily, quantities, and types of products) in the months before and after legalization.
