Prevalence of E-Cigarette Use Among US Adults

Ann Intern Med; 2018 Oct 2; Mirbolouk, et al

E-cigarette use is common in the US, especially among younger adults, lesbian, gay, bisexual, and transgender (LGBT) persons, current cigarette smokers, and those with comorbid conditions. This according to a recent cross-sectional study that examined the prevalence and distribution of e-cigarette use among US adults in 2016. Participants aged ≥18 years were grouped by sociodemographic, comorbid medical conditions, and states of residence. Researchers found:

  • Of participants with information on e-cigarette use (n=466,842), 15,240 were current e-cigarette users (prevalence 4.5%), which corresponds to 10.8 million adult e-cigarette users in the US.
  • The prevalence of current e-cigarette use was highest among persons aged 18-24 years (9.2%).
  • More than half of current e-cigarette users (51.2%) were aged <35 years.
  • Age-standardized prevalence of e-cigarette use was high among men, LGBT persons, current combustible cigarette smokers, and those with chronic health conditions.
  • The prevalence of e-cigarette use differed widely across states.
