SAN LUIS VALLEY — A new study released by the University of Michigan’s Institute for Social Research Dec. 14 shows that marijuana use among adolescents saw a sharp upward climb in 2017, the first significant increase researchers have noted in seven years.
The study shows past-year use of marijuana significantly increased by 1.3 percent to 24 percent for eighth and 12th graders combined in 2017. In grades eight, 10 and 12 specific increases were 0.8 percent (to 10.1 percent), 1.6 percent (to 25.5 percent) and 1.5 percent (to 37.1 percent). The increase is statistically significant when all three grades are combined.
“This increase has been expected by many,” Richard Miech, principal investigator of the study said. “Historically marijuana use has gone up as adolescents see less risk of harm in using it. We’ve found that the risk adolescents see in marijuana use has been steadily going down for years to the point that it is now at the lowest level we’ve seen in four decades” (http://monitoringthefuture.org/pressreleases/17drugpr.pdf ).
