A U.S. government study has found that vaping rates among young students fell sharply this year. The drop comes after last year’s sudden increase in vaping-related illnesses and deaths. The national survey, released this week, showed that just under 20 percent of high school students said they were recent users of e-cigarettes and other vaping products. Just 5 percent of middle school students said they had recently used them. That marks a big decrease from a similar survey in 2019. The earlier survey found nearly 28 percent of high school students and 11 percent of middle school students had recently vaped. The 2020 survey was carried out by the Centers for Disease Control and Prevention (CDC) in partnership with the U.S. Food and Drug Administration (FDA).
