E-cigarette prevalence by sex and age group

Ever Use

Prevalence of ever using e-cigarettes was significantly higher among males in all age groups except those age 45 and older^147-151 (Figure 12.5). Sex differences were most pronounced among young adults.

Past 30-day Use

While prevalence of e-cigarette use in the past 30 days was much lower than ever use, similar patterns were observed: past 30-day use was more prevalent among male youth and young adults,^152,153 but there were no significant sex differences among older age groups^154,155 (Figure 12.6).
