Changes in Perceived Risk
• A large majority of 12th graders perceive that regular use of any illicit drug presents great risk of harm for the user.
• In 2015, 85 percent of 12th graders perceived great risk of harm from regular use of heroin (85%), crack (81%), cocaine (79%), and LSD (61%).
• Among the illicit drugs, marijuana has the lowest perceived risk, with approximately one-third (32%) thinking regular use carries great risk.
• Substantial proportions of 12th graders view even experimenting (i.e., using once or twice) with most of the illicit drugs as risky. But only 12 percent of 12th graders see experimenting with marijuana as entailing great risk.
• Only 32 percent of 12th graders perceive risk of harm from regular marijuana use, which is its lowest level ever. Between 2006 and 2015, perceived risk of regular use generally declined, while current use (i.e., past 30 days) rose steadily, at least through 2012.
