The latest data from the nationally representative Monitoring the Future study shows the single-largest year-to-year increase in substance use in the US for 10th and 12th graders due to vaping. From 2017 to 2018 past-month vaping of nicotine nearly doubled among high school seniors from 11% to 21%, and did double among sophomores from 8% to 16%. Not surprisingly, the increases seen in vaping nicotine were mirrored with significant increases in vaping marijuana among 8th, 10th and 12th graders. Lead study researcher Richard Miech PhD noted that “Factors that make vaping so attractive to youth include its novelty and the easy conceal-ability of the latest vaping devices, which better allows youth to vape without adults knowing about it. If we want to prevent youth from using drugs, including nicotine, vaping will warrant special attention in terms of policy, education campaigns, and prevention programs in the coming years.” Read more.
