As shown in Figure 11.9, use of e-cigarettes varied greatly by smoking status, including for ever, past 30-day and daily prevalence.102-104
Nearly half (47.5%a) of current smokers (including daily and non-daily smokers) had ever used e-cigarettes, compared to 13.0%b of non-smokers (including former and never smokers). Similarly, past 30-day use was 16.5%c among current smokers and just 3.3%d among non-smokers, and daily use was 5.7%e among current smokers and 1.9%f among non-smokers.
Since 2013, ever use of e-cigarettes appears to have increased among all groups, with the largest increases among non-daily and former smokers in the most recent years (Figure 11.10). While prevalence among never smokers was lower than other groups, ever use increased more than three-fold between 2013 and 2020 in this group.

From 2013 to 2020, past 30-day use of e-cigarettes also appears to have increased in all smoking status groups (Figure 11.11). Prevalence was greater among smokers throughout this time, but increases were greater among non-daily smokers in recent years.
Daily use of e-cigarettes also appeared to increase more among non-daily smokers than other groups, particularly in the most recent years (Figure 11.12).
Prevalence among males and females, by smoking status
Among smokers, ever use of e-cigarettes (Figure 11.13) was significantly more prevalent among males than females.105 While past 30-day use followed a similar pattern (Figure 11.14), the difference in prevalence was not significantly different between male and female smokers.106 Daily use of e-cigarettes was not reportable among female smokers (Figure 11.15), but no significant difference was observed between male and female smokers (potentially due to small sample size).107
Among non-smokers, ever use, past 30-day use, and daily use of e-cigarettes were all significantly more prevalent among males.108-110

Prevalence by age group and smoking status
Prevalence of using e-cigarettes differed significantly by age among both smokers and non-smokers.111,112 While smokers had much higher prevalence than non-smokers, the same pattern of greater use among youth and younger adults, declining with age, was observed in both groups (Figure 11.16, Figure 11.17).

Daily use of e-cigarettes followed a pattern similar to past 30-day use, although at lower prevalence levels. Significant differences were observed by age group among both smokers and non-smokers,115,116 with greater daily prevalence among younger age groups, although the estimate for daily use among smokers age 25 and older was not reportable (Figure 11.20; Figure 11.21).
