The Canadian Student Tobacco, Alcohol and Drugs Survey (CSTADS), formerly the Youth Smoking Survey (YSS), is a biennial survey administered to students in grades 7-12 across Canada. CSTADS is implemented with the cooperation, support and funding of Health Canada.

CSTADS collects data on topics such as:

  • Tobacco use
  • Alcohol use
  • Drug use
  • Bullying
  • School connectedness
  • Mental health
CSTADS will provide Health Canada, provinces, schools, communities, and parents with timely and reliable data on tobacco, alcohol and drug use as well as other issues that relate to Canadian students.
