Figure 3.1 is a bar chart showing the prevalence of past year marijuana use among youths aged 12 to 17 by community domain risk factors. The chart indicates the percentage of youths who have used marijuana was higher among youths who reported higher levels of community disorganization and crime, among youths who reported that neighborhood adults would not strongly disapprove if the youth were to use marijuana, among youths who personally knew adults who use marijuana, and among youths with easy access to marijuana.
