The Canadian Substance Use Survey (CSUS) is a comprehensive survey offering vital insights into Canadians’ use of alcohol, psychoactive pharmaceuticals, and drugs. It measures prevalence, high risk consumption patterns and related harms, from people aged 15 and older. Data are collected every other year, and are used to support evidence-based policy and health interventions aimed at reducing substance-related harms and improving public well‑being in Canada. Summary results from each cycle are available here: https://www.canada.ca/en/health-canada/services/canadian-alcohol-drugs-survey.html The Office of Drug Research and Surveillance releases this Public Use Microdata File (PUMF) to allow researchers, provincial governments, and others to conduct independent analyses of these data.
