Ever Use
Prevalence of ever using e-cigarettes varied significantly by age group:131 use was highest among young adults aged 20-24 and 25-34, as well as youth, and decreased with age into adulthood (Figure 12.3). Between 2015 and 2017, ever use significantly increased only among adults aged 25-34 and 35-44.132-136
Among youth aged 15-19, the prevalence estimate for ever trying e-cigarettes was higher than for cigarettes (16.4%)a or any other tobacco product (see Figure 10.1).

Past 30-day Use
Past 30-day use of e-cigarettes also varied significantly by age group:137 prevalence was highest among youth and young adults (Figure 12.4). Between 2015 and 2017, past 30-day use did not change significantly in any age group.138-141
Among youth aged 15-19, past 30-day use of e-cigarettes was comparable to cigarette smoking, which was reported by 6.6%b.
Of those who reported ever trying an e-cigarette, use in the past 30 days varied significantly by age group:142 27.6%c of ever-users aged 15-19 had used an e-cigarette in the past 30 days, as well as 20.7%d aged 20-24, 14.6%e aged 25-44, and 20.9%f aged 45 and older.

Daily Use
Overall prevalence of daily e-cigarette use varied significantly by age group,143 reported by 1.8%g of young people aged 15-24, 1.2%h of adults aged 25-44, and 0.6%i adults age 45 and older.
However, of those reporting using e-cigarettes in the past 30 days, the proportion using daily did not differ significantly by age group:144 29.8%j of users aged 15-24, 39.2%k of users aged 25-44, and 32.0%l aged 45 and older.
Similarly, among past 30-day users, the proportion using e-cigarettes on 20 or more of the past 30 days did not differ significantly by age group (35.1%m among age 15-19, 31.1%n among 20-24, 45.7%o among 25-44, and 34.7%p among 45+).145
The mean days of use in the past 30 were also similar across age groups (13.5q among age 15-19, 11.3r among 20-24, 15.2s among 25-44, and 12.7t among 45+).146
