Millions of Americans use electronic cigarettes (e-cigarettes). E-cigarettes may enable some people to quit smoking, but they may encourage others to start smoking, including susceptible populations, such as young people.1 Despite an increase in the number of people trying e-cigarettes, current use of e-cigarettes among US adults declined from 2014 to 2017 (weighted prevalence: 2014, 3.7%; 2015, 3.5%; 2016, 3.2%; 2017, 2.8%).2,3 Recently, the US Centers for Disease Control and Prevention reported a startling rise in e-cigarette use among US middle school and high school students between 2017 and 2018, reversing the previously observed decline since 2015.4 This may be at least partly attributable to the recent popularity of pod-based e-cigarettes, such as the Juul brand.4 It is imperative to update the recent changes in e-cigarette use in adults to inform future research and policy. We updated data on adult e-cigarette use to include 2018 and examined the changes between 2017 and 2018.
