E-cigarette prevalence by smoking status

 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. Data Source: Canadian Tobacco, Alcohol and Drugs Survey, 2015. See data table with 95% confidence intervals below.As shown in Figure 12.10, prevalence of e-cigarette use varied greatly by smoking status, both for ever use143 and past 30-day use.144

Half (51.0%) of current smokers (including daily and non-daily smokers) had ever used e-cigarettes, compared to 7.6% of non-smokers (including former and never smokers). Similarly, past 30-day use was 15.5% among current smokers and just 1.4% among non-smokers.

Prevalence by sex, among smokers and non-smokers

 Canadian Tobacco, Alcohol and Drugs Survey, 2015. See data table with 95% confidence intervals below.As shown in Figure 12.11, prevalence of using e-cigarettes was similar among male and female smokers for both ever use and past 30-day use.145,146

Among non-smokers, ever-use of e-cigarettes was significantly more prevalent among males,147 but past 30-day use did not differ significantly by sex.148

Prevalence by age group, among smokers and non-smokers

While there were large differences between smokers and non-smokers in ever use of e-cigarettes, the same pattern of high use among youth and young adults, declining with age, was observed in both groups (Figure 12.12, Figure 12.13).149,150

Use of e-cigarettes in the past 30 days also varied by smoking status and age group,151,152 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 12.14, Figure 12.15).
