Please note: The proportion of school students who regularly used cannabis differs from the proportion of youth in the general population who regularly used cannabis due to differences in survey measures (see FAQ: Are younger or older Australians in the general population aged 12-17 years more likely to regularly use cannabis?). In the Australian Secondary School Students’ Alcohol and Drug (ASSAD) survey, regular use is defined as using cannabis 10 or more times in the past year, while in the general population survey (National Drug Strategy Household Survey) regular use is defined as using 12 or more times in the past 12 months.

Regular Cannabis Use: Regular cannabis use refers to using cannabis 10 or more times in the past year (in the case of ASSAD data), or at least once per month or 12 times in the past year (in the case of NDSHS data).
