Researchers estimate that half of all high school students in the United States have tried vaping at least once. One third of these students vape regularly. Since e-cigarettes were introduced to the U.S. in 2013, they’ve become more and more popular, especially among teens. From 2019-2020, the popularity of disposable e-cigarette use among U.S. high school students who currently vaped went up by 1,000%, from 2.4% to 26.5%, according to the CDC.
