Nicotine in e-cigarettes

The implementation of the Tobacco and Vaping Products Act allowed the sale of nicotine-containing e-cigarettes in 2018 , prior to which nicotine-containing e-cigarettes were not approved for sale in Canada.^xiiiIn June 2021, new federal regulations established a maximum nicotine concentration of 20mg/ml in e-liquids.^xiv

Ever-users of e-cigarettes were asked on how many of the past 30 days they had used an e-liquid with nicotine, an e-liquid without nicotine, and an e-liquid they “did not know what it contained”, respectively. In 2020, most (84.4%^a) said they had used an e-liquid with nicotine on at least one day, while just 21.1%^b said they had used an e-liquid without nicotine on at least one day, and one in ten (10.1%^c) said they had used an e-liquid they “did not know what it contained” on at least one day.

The percentage of past 30-day vapers who reported using an e-liquid with nicotine on at least one day in the past 30 was similar to the 2019 estimate of 84.1%^d.¹³⁵

Prevalence of using a nicotine-containing e-liquid in the past 30 days did not vary significantly by smoking status¹³⁶ (Figure 11.30); among past 30-day e-cigarette users, most current smokers (82.1%^e), former smokers (88.4%), and never smokers (82.8%) had used e-cigarettes containing nicotine in the past 30 days.

Figure 11.30: Percentage of past 30-day e-cigarette users who used an e-liquid with nicotine on at least one day in the past 30 days, by smoking status, 2020
Smoking status	%
Daily smoker	79.7 [67.5-91.9]
Non-daily smoker	88.1 [78.0-98.1]
Former smoker	88.4 [80.8-95.9]

Daily smoker: responded "daily" to "during the past 30 days, how often did you smoke cigarettes?"
Non-daily smoker: responded "less than daily, but at least once a week" or "less than once a week, but at least once in the past month" to past 30-day smoking.
Former smoker: responded "not at all" to past 30-day smoking but "yes" to "have you smoked at least 100 cigarettes (about 4 packs) in your life?"
