Tobacco use by U.S. youth is on the rise, and the increase is driven by e-cigarettes, officials say.
More than one in four high school students in 2018 had used a tobacco product in the past 30 days, according to the Centers for Disease Control and Prevention.
E-cigarette use by high school students went up from about 12 percent in 2017 to 21 percent in 2018.
No change was found in the use of other tobacco products during this time.
E-cigarettes are the most commonly used tobacco product among youth.
