Characterizing polysubstance use: What do we know about use of cigarettes, vaping products, cannabis, and alcohol among Canadians?

Description: Polysubstance use—the use of multiple substances on the same or different occasions—is a risk factor for substance use disorder. However, national surveillance of substance use in Canada has often focused on use of a single substance. To better understand and address polysubstance use, this study characterized the use of vaping products, cigarettes, inhaled cannabis, and alcohol among Canadians aged 15 years and older. Nationally representative data from the 2020 Canadian Tobacco and Nicotine Survey were analyzed.
