Treatment of Adolescent e-Cigarette Use: Limitations of Existing Nicotine Use Disorder Treatment and Future Directions for e-Cigarette Use Cessation.

Electronic cigarette use ("vaping") has surged in the United States since the mid-2010s. From 2011 to 2018, current e-cigarette use among high school students escalated from 1.5% to 20.8% (∼3.05 million youths),1 countering downward trends in combustible nicotine product use (21.8% in 2011 to 13.9% in 2018).1 Although preventing the initial uptake of vaping is crucial, for the millions of adolescents who have taken up this behavior-many of whom express interest in quitting (eg, 44.5% of current, adolescent non-light e-cigarette users in one US national representative sample)2-it is critically important to help them quit vaping so as to curtail future substance use disorders and other health consequences. Here, we discuss several challenges around adolescent vaping treatment, and highlight research areas in urgent need of attention.
