Abstract
Additionally, 23.1% of e-cigarette users reported never smoking, and most were younger than 35 years. In addition to the potential health effects of vaping, 3 the young age of many users is concerning, particularly as nicotine is highly addictive and can negatively affect brain development, which continues until age 25 years. mitations of this study include a cross-sectional design and self-reported data. Strengths of these analyses include recency of the data and a large nationally representative sample, which makes the findings generalizable. e-Cigarettes are now used by large numbers of never, former, and current cigarette smokers in the US population. Given the rapidly changing e-cigarette marketplace and recent increases in the prevalence of use among youth 5 and young adults, 6 continued surveillance is needed.
