Trends in Prevalence of Cannabis Use Among Youth

"Over time, with the exception of cannabis, there is no significant variation in the lifetime prevalence of any substance use. For cannabis in particular, following the decline recorded from 2002 to 2006, prevalence rates increased between 2006 and 2010 (Figure 2.3), with the increase being significant only among boys.
"It is to be noted that the increase in cannabis use prevalence from 2006 to 2010 reflects all, lifetime use (3.7% and 7.2%, respectively), last year use (3.1% and 6.3%, respectively) and last month use (2.2% and 4.1%, respectively). The increase in cannabis prevalence also applies to trying the substance 1 or 2 times (1.6% and 3%, respectively) and to using the substance more than 3 times (2.1% and 4.2%, respectively)."
