This report presents national secondary student alcohol and other substance use data from the 2022/2023 Australian Secondary Students’ Alcohol and Drug (ASSAD) survey. The ASSAD survey is the largest national survey of adolescent substance use in Australia, and is administered on school premises (i.e., without parental involvement), which has been shown to result in higher (and likely more valid) estimates of health risk behaviours compared to surveys conducted in the home setting.10

The report examines students’ prevalence of drinking and other substance use in 2022/2023 and over time. We further present data on students’ behaviours relating to the use of alcohol, over-the-counter drugs (for non-medical reasons) and cannabis.
