Attitudes of Young People Toward Legalization of Marijuana
" Table 8-8 lists the proportions of 12th graders in 2013 who favor various legal consequences for marijuana use: making it entirely legal (42%), a minor violation like a parking ticket but not a crime (25%), or a crime (21%). The remaining 13% said they 'don’t know.' It is noteworthy just how variable attitudes about this contentious issue are.
" Asked whether they thought it should be legal to sell marijuana if it were legal to use it, about three in five (61%) said 'yes.' However, about 85% of those answering 'yes' (52% of all respondents) would permit sale only to adults. A small minority (9%) favored the sale to anyone, regardless of age, while 29% said that sale should not be legal even if use were made legal, and 10% said they 'don’t know.' Thus, while the majority subscribe to the idea of legal sale, if use is allowed, the great majority agree with the notion that sale to underage people should not be legal."
