Daily cigarette smoking is down to just 1.3% among eighth graders, 3% among 10th graders, and 5.5% for high school seniors. Five years ago, the daily smoking rates were 2.9%, 6.6%, and 6.7%, respectively. A similar decline was seen when past-month alcohol use was analyzed in eighth, 10th, and 12th graders. The bad news from the MTF study? Marijuana use among high school eighth, 10th, and 12th graders remained steady over a five-year period, with 6.5%, 14.8%, and 21.3%, respectively, admitting to smoking marijuana within the past month. A full 6% of high school seniors admit to smoking marijuana daily. Perhaps most surprising, just 31.9% of today’s students view occasional marijuana smoking as harmful compared to 78.6% in 1991. Data source: University of Michigan via NIDA. To sum up MTF’s findings: High school seniors now smoke marijuana daily more often than they do cigarettes.
