Please note: The proportion of school students who regularly use cannabis differs from the proportion of young people in the general population who regularly use cannabis (see FAQ What proportion of Australians in the general population aged 12-17 years regularly use cannabis?). This is due to the use of different survey measures. In the school students’ survey (ASSAD), regular use is defined as using cannabis 10 or more times during the past year. By contrast, in the general population survey (NDSHS) regular use is defined as using cannabis 12 or more times during 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).
