E-cigarette prevalence by smoking status

See data table below with 95% confidence intervals. As shown in Figure 12.9, prevalence of e-cigarette use varied greatly by smoking status, both for ever use¹⁶⁰ and past 30-day use.¹⁶¹

Half (54.1%^a) of current smokers (including daily and non-daily smokers) had ever used e-cigarettes, compared to 8.5%^b of non-smokers (including former and never smokers). Similarly, past 30-day use was 12.3%^c among current smokers and just 1.2%^d among non-smokers. Daily e-cigarette use was 3.0%^e among current smokers and 0.6%^f among non-smokers.

Figure 12.9: Ever use and past 30-day use of e-cigarettes by smoking status among Canadians age 15+, 2017
Smoking status	Ever use	Past 30-day use	Daily use
Daily smoker	54.0 [47.9-60.2]	12.9 [8.8-17.1]	1.9 [0.7-3.1]
Non-daily smoker	54.3 [44.3-64.2]	10.8 [6.3-15.4]	5.8 [2.7-8.8]
Former smoker	12.9 [9.9-15.9]	2.2 [1.2-3.3]	1.7 [0.8-2.6]
Never smoker	6.7 [5.5-7.8]	0.7 [0.5-1.0]	0.1 [0.1-0.2]

Daily smoker: responded "every day" to "At the present time do you smoke cigarettes every day, occasionally or not at all?"; Non-daily smoker: responded "occasionally" to "At the present time do you smoke cigarettes every day, occasionally or not at all?"; Former smoker: smoked “not at all” at the time of the survey, but had smoked 100+ cigarettes in lifetime

Prevalence by sex, among smokers and non-smokers

See data table below with 95% confidence intervals. As shown in Figure 12.10, prevalence of using e-cigarettes was similar among male and female smokers for both ever use and past 30-day use.^162,163

Among non-smokers, ever-use of e-cigarettes was significantly more prevalent among males,¹⁶⁴ but past 30-day use did not differ significantly by sex.¹⁶⁵

This pattern held among youth aged 15-19, with greater sex differences observed among non-smokers than smokers (data not shown).

E-cigarette use	Smoking status	Male	Female
Ever use	Smoker	56.2 [49.3-63.2]	51.6 [43.7-59.5]
Ever use	Non-smoker	11.4 [9.3-13.6]	5.8 [4.7-7.0]

Smokers includes daily and non-daily smokers; Non-smokers includes former and never smokers

Prevalence by age group, among smokers and non-smokers

Prevalence of using e-cigarettes differed significantly by age among both smokers and non-smokers.^166,167While 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 12.11, Figure 12.12).

See data table below with 95% confidence intervals.

Use of e-cigarettes in the past 30 days also varied by smoking status and age group,^168,169 again with much higher use observed among smokers than non-smokers and similar patterns by age group, although at much lower prevalence levels than for ever use (Figure 12.13, Figure 12.14).
