E-cigarette prevalence among males and females

Ever use of e-cigarettes was significantly more prevalent among males, at 19.5% (3.0 million), compared to 13.7% of females (2.2 million) (Figure 11.2).⁶⁵

Similarly, e-cigarette use in the past 30 days was significantly more prevalent among males (5.7%) than females (3.6%),⁶⁶as was daily use of e-cigarettes,⁶⁷ which was 2.9% among males compared to 1.7% of females (Figure 11.2).

However, the magnitude of differences between males and females appeared to vary by age group.
