Smoking status of e-cigarette users

Half (49.9%) of ever users and a majority (62.8%) of past 30-day users of e-cigarettes were current smokers, suggesting that dual use of cigarettes and e-cigarettes is high. One-quarter of ever and recent (past 30 day) e-cigarette users were former smokers. One-quarter of ever users and 12.8% of recent users of e-cigarettes had never been a smoker, indicating some interest among non-smokers (Figure 12.16; Figure 12.17). There were no differences between males and females in the percentages of ever or past 30-day users who were smokers (49.4% vs. 50.5% and 64.6% vs. 60.6%, respectively).153,154
