Disapproval of Drug Use Among 12th Graders in the US

"The vast majority of 12th graders disapprove of regular use of any of the illicit drugs (see Table 8-6). Among 2015 12th graders, 71% disapprove (including strongly disapprove) of regular marijuana use and between 92% and 96% disapprove of regular use of each of the other illicit drugs. (Regular steroid use meets with an 88% disapproval rate.)
"• For each of the drugs included in this set of questions, fewer respondents indicate disapproval of experimental or occasional use than of regular use. However, the differences are not great for the use of illicit drugs other than marijuana, because nearly all 12th graders disapprove of even experimenting with them. For example, the proportions disapproving of experimental use are 94% for heroin; 89% for cocaine; 90% for crack; 87% for sedatives (barbiturates); 86% for cocaine powder; 82% for LSD; and 85% for ecstasy (MDMA). The extent of disapproval of illicit drug use by peers is no doubt underestimated by adolescents and, as we have written for some time, the extent of disapproval that actually does exist could be widely publicized and provide the basis for some potentially powerful prevention messages in the form of normative education.10
"• For marijuana, the rate of disapproval varies substantially for different usage levels, although not as much as it has in the past. Disapproval for this drug is really quite high. About half of all seniors (46%) disapprove of even trying marijuana once or twice, about three of five (53%) disapprove of its occasional use, and three of four (71%) disapprove of regular use. Looked at another way, only about one quarter of 12th graders (29%) say they don’t disapprove of regular marijuana use."
