Cannabis & illicit drug use: trends and risk behaviours
We have conducted a range of studies to examine patterns of cannabis use among Canadians, including changes over time, as well as risk behaviours. As Canada prepares to legalize recreational cannabis in 2018, this evidence will be important to monitor trends to help understand the impact of legalization on cannabis use and the drug market more broadly.
