Australian Secondary Students’ Alcohol and Drug Survey

Secondary school students in Western Australia have been taking part in the Australian Secondary Students’ Alcohol and Drug (ASSAD) Survey since 1984. The triennial survey explores prevalence and trends of secondary student substance use, with students asked about their use and attitudes related to tobacco, electronic cigarettes, alcohol, non-medical use of pharmaceutical drugs and illicit drugs.

Why this research matters

ASSAD provides ongoing information about the prevalence of smoking, vaping, alcohol and other drugs use and behaviours among school students, and analyses of trends over time. The results provide useful information to inform policy, planning and evaluation of interventions and programs for young people.
