ASSAD Marijuana use


    Marijuana use: ever, last year, last month, last week, ACT Secondary Students aged 12-17 years, 1996-2017


    Since 1996, there has been a significant decrease in the proportion of ACT  secondary students surveyed reporting that they have ever used marijuana (1996: 35.8%; 2017: 13.5%). Similarly, the prevalence of marijuana use in the last year, last month and last week has also declined over time. In 2017, 12.0% of secondary students surveyed reported that they had used marijuana in the last year; 4.5% had used it in the last month and 2.1% had used it in the last week.

    Please note that this indicator was updated in 2022 and replaces all previous versions. 

    The following estimates have a relative standard error between 25% and 50% and should be used with caution:

    2017 used marijuana in the last month
    2008 and 2017 used marijuana in the last week

    For the purpose of reporting the Australian Secondary Students' Alcohol and Drug survey data on HealthStats, if the 95% confidence intervals of the estimates do not overlap, they are considered to be significantly different.
