Please note: The proportion of school students who have used cannabis differs from the proportion of young people in the general population who have used cannabis (see FAQ Are younger or older Australian school students aged 12-17 years more likely to have used cannabis?). This is due to the use of different survey measures. The school students’ survey (ASSAD) asks respondents to record the frequency of their cannabis use (0-40 times) in the past year, month, and week. By contrast, the general population survey asks respondents to record whether or not they used cannabis in the past year, month, and week.
