"Crack cocaine use spread rapidly from the early to mid-1980s. Still, among 12th graders, the use of crack remained relatively low during this period (3.9% annual prevalence in 1987). Clearly, crack had quickly attained a reputation as a dangerous drug, and by the time of our first measurement of perceived risk in 1987, it was seen as the most dangerous of all drugs. Annual prevalence dropped sharply in the next few years, reaching 1.5% by 1991, where it remained through 1993.
Monitoring The Future
" Table 8-8 lists the proportions of 12th graders in 2018 who favor various legal consequences for marijuana use. The proportion who believe it should be entirely legal was 48%, near the record high set the previous year of 49%. As the percentage favoring legality increased, the percentage believing marijuana use should be a crime decreased and in 2018 was 11%, the lowest level recorded by the survey, having fallen from a peak of 53% in 1990.
