Ontario Student Drug Use and Health Survey (OSDUHS)

The OSDUHS is a population survey of Ontario students in Grades 7 through 12. The OSDUHS began in 1977 and is the longest ongoing school survey in Canada, and one of the longest in the world. This self-administered, anonymous survey is conducted across the province every two years with the purpose of identifying epidemiological trends in student drug use, mental health, physical activity, and risk behaviour, as well as identifying risk and protective factors.
