Please note: The proportion of youth in the general population who have used cannabis in the past 12 months, past month, and past week differs from the proportion of school students who have used cannabis in the past year, past month, and past week (see FAQ: What proportion of Australian school students aged 12-17 years has used cannabis?). These differences may be due to differences in survey measures. In the Australian Secondary School Students’ Alcohol and Drug (ASSAD) survey, respondents are asked about their frequency of use (none to 40 times or more) in the past year, past month, and past week. In the general population survey (National Drug Strategy Household Survey), respondents are simply asked if they had used cannabis in the past 12 months, past month, or past week.
