Tobacco product use among US youth is increasing. More than 1 in 4 high school students and about 1 in 14 middle school students in 2018 had used a tobacco product in the past 30 days. This was a considerable increase from 2017, which was driven by an increase in e-cigarette use. E-cigarette use increased from 11.7% to 20.8% among high school students and from 3.3% to 4.9% among middle school students from 2017 to 2018. No change was found in the use of other tobacco products, including cigarettes, during this time.
