E-Cigarettes: Perceived harm among Youth in the United States.

Emerging nicotine delivery systems, such as e-cigarettes, offer a new way for
tobacco experimentation and use among youth (U.S. Department of Health and Human
Services [USDHHS], 2016). E-cigarettes dominated debates about innovative tobacco
product development within the tobacco harm trajectory. The long-term health effects of
e-cigarettes are unknown, yet these products have increased in popularity and use among
youth in the United States (US; Corey et al., 2013). Between 2017 and 2018, e-cigarette
use increased among middle and high school students, by 48% and 78%, respectively
(Cullen et al., 2018). In 2018, more than three million middle and high school students
were e-cigarette users (Cullen et al., 2018).
