Teens aren’t drinking as much as they used to, and they’re smoking fewer cigarettes than ever. In fact, researchers for the annual Monitoring the Future report say most types of drugs—from cocaine to prescription drugs—have taken a dip in popularity. The one big exception? Marijuana. According to an updated study from the institute, 23 percent of high schoolers smoked pot in the past month (just 19 percent of teens smoke cigarettes monthly), and 7 percent of high school seniors smoke the stuff daily—the highest that figure’s been since 1981. In addition, 11 percent of seniors say they’ve used synthetic marijuana (often supplementing their use of the real stuff), which until recently was legal in some states and marketed under names such as K2 or Spice. The survey, funded by the National Institute on Drug Abuse, found that most teens don’t think pot is dangerous; and researchers warn that perception means usage will continue to increase. “We are heartened by some of the results,” said Dr. Howard Koh, assistant secretary for health for the Department of Health and Human Services, “but there is much more work to do.” (Los Angeles Times)
