ANN ARBOR — National samples of 45,000 to 50,000 students in three grades (8, 10, and 12) have been surveyed every year since 1991 as part of the nationwide Monitoring the Future study. Among the most important findings from this year’s survey of U.S. secondary school students are the following:
Marijuana. After four straight years of increasing use among teens, annual marijuana use showed no further increase in any of the three grades surveyed in 2012. The 2012 annual prevalence rates (i.e., percent using in the prior 12 months) were 11%, 28%, and 36% for 8th, 10th, and 12th graders, respectively. (Among the 8th graders there was a modest decline across the past two years—from 13.7% in 2010 to 11.4% in 2012—that reached statistical significance.) (more…)
ANN ARBOR, Mich.— Among the more important findings from this year’s Monitoring the Future survey of U.S. secondary school students are the following:
- Marijuana use among teens rose in 2011 for the fourth straight year—a sharp contrast to the considerable decline that had occurred in the preceding decade. Daily marijuana use is now at a 30-year peak level among high school seniors.
- “Synthetic marijuana,” which until earlier this year was legally sold and goes by such names as “K2” and “spice,” was added to the study’s coverage in 2011; one in every nine high school seniors (11.4%) reported using that drug in the prior 12 months.
- Alcohol use—and, importantly, occasions of heavy drinking—continued a long-term gradual decline among teens, reaching historically low levels in 2011.
- Energy drinks are being consumed by about one third of teens, with use highest among younger teens. (more…)
