QuickStats: Cigarette Smoking Status* Among Current Adult E-cigarette Users, by Age Group — National Health Interview Survey,§ United States, 2015


 The figure above is a bar chart showing that in 2015, 3.5% of U.S. adults were current e-cigarette users. Among adult e-cigarette users overall, 58.8% also were current cigarette smokers, 29.8% were former cigarette smokers, and 11.4% had never been cigarette smokers. Among current e-cigarette users aged ≥45 years, 98.7% were either current or former cigarette smokers, and 1.3% had never been cigarette smokers. In contrast, among current e-cigarette users aged 18–24 years, 40.0% had never been cigarette smokers.

* Adults were asked if they had smoked at least 100 cigarettes in their lifetime and, if yes, whether they currently smoked cigarettes every day, some days, or not at all. Those who smoked every day or some days were classified as current cigarette smokers. Adults who had not smoked 100 cigarettes were classified as never cigarette smokers. Adults who had smoked 100 cigarettes but were not smoking at the time of interview were classified as former cigarette smokers. Percentages are shown with 95% confidence intervals.

Current e-cigarette use was based on responses of“every day”or“some days”to the question,“Do you currently use electronic cigarettes every day, some days, or not at all?”asked of adults who had ever tried an e-cigarette, even one time.

§ Estimates are based on household interviews of a sample of the noninstitutionalized U.S. civilian population aged ≥18 years and are derived from the National Health Interview Survey sample adult component.
