Rates of teen cannabis use in Canada have remained largely unchanged in the years following the adoption of adult-use legalisation, according to data published in the journal Drug and Alcohol Dependence Reports. Health Canada officials review youth use data for the years prior to legalisation and afterward (the Canadian Student Alcohol and Drugs Survey is a biennial, repeat cross-sectional survey of grade 7-12 students in the Canadian provinces).
They reported, “Overall, there was no change in prevalence of past 12-month, past 30-day, or frequent cannabis use” among students in grades 7 to 12. Vaping surpassed smoking as the most common method of consumption in 2023-24, whilst dabbing cannabis decreased over time. Researchers also reported no changes in young people’s age of cannabis initiation or in the percentage of teens who acknowledge driving after consuming cannabis.
