Dai H, Leventhal AM. Prevalence of e-Cigarette Use Among Adults in the United States, 2014-2018. JAMA. 2019;322(18):1824–1827. doi:10.1001/jama.2019.15331
Prevalence of e-cigarette use among US adolescents substantially increased from 2017 to 2018.1 Whether prevalence also increased among young adults (18-24 years)—a population with high vaping rates2 and vulnerability to nicotine dependence and other health consequences of nicotine exposure3—is unknown.
Prevalence of current e-cigarette use decreased among all US adults between 2014 and 2016.4 This study examined 2014-2018 trends and the 2017-2018 biannual change in prevalence of e-cigarette use in US adults of different ages. Among young adults, e-cigarette use trends by sociodemographic and smoking status were also examined.
Respondents were from 2014-2018 National Health Interview Surveys—annual cross-sectional household face-to-face interviews of nationally representative noninstitutionalized US civilian samples (household response rates, 64.2%-73.8%).5 The University of Nebraska institutional review board determined this study to be non–human subjects research.
