Young People in the US Report Declining Availability of Marijuana

"Marijuana has been the most consistently available illicit drug and has shown only small variations over the years (see Figure 9-5a). What is most noteworthy is how little change has occurred in the proportion of 12th graders who say that marijuana is fairly or very easy to get. By this measure, marijuana has been readily available to the great majority of American 12th graders (from 80% to 90%) since 1975.

"While variability has been small over the course of the survey, perceived availability of marijuana is at or near historic lows in each grade. In 2017 in 8th grade it was 35% (tied with 2016 for a historic low), in 10th grade it was 65% (the second lowest level recorded by the survey, just above the 2016 low), and in 12th grade it was at 80% (the second lowest level recorded, just above the 2016 low). This decline in perceived availability is somewhat counter-intuitive, given the widespread adoption of medical marijuana laws and recent legalizing of recreational marijuana use for adults in several states."
