A large survey reveals that most adult users of e-cigarettes in the United States also smoke tobacco cigarettes.
Among surveyed current e-cigarette users age 18 and older in 2015, 58.8% of e-cigarette users reported also smoking tobacco cigarettes in the CDC’s National Health Interview Survey (NHIS).
Just under a third (29.8%) of e-cigarette users reported being former smokers and 11.4% reported having never smoked cigarettes.
Some 3.5% of U.S. adults were current e-cigarette users in 2015, according to the NHIS data.
The survey results were released Oct. 27 in the CDC’s Morbidity and Mortality Weekly Report.
Current e-cigarette use was defined as vaping “every day” or “some days,” and respondents who reported smoking tobacco cigarettes “every day” or “some days” were classified as current cigarette smokers. Respondents with a history of smoking 100 or more cigarettes who reported no current cigarette use were classified as former cigarette smokers.
