Prevalence of Marijuana Use Among Canadians Aged 15 and Older
"The prevalence of past-year cannabis use among Canadians aged 15 years and older was 10.2% in 2012, unchanged from 9.1% in 2011, but lower than in 2004 (14.1%). There was an increase in past-year cannabis use among adults aged 25 years and older to 8.4% in 2012 from 6.7% in 2011, and no change from 2011 among youth aged 15 to 24 years. However, the prevalence of past-year cannabis use among youth (20.3%) remains higher than that of adults (8.4%). Youths initiated use of cannabis at an older age in 2012 than in 2011 (16.1 versus 15.6 years).
"The prevalence of past-year cannabis use in 2012 was lower than in 2004 among males (13.7% versus 18.2%), females (7.0% versus 10.2%) and youth aged 15 to 24 years (20.3% versus 37.0%), with the prevalence among males remaining twice as high as that of females (13.7% versus 7.0%, respectively). Prevalence among adults aged 25 years and older was unchanged between 2012 and 2004."
