Introduction:
Electronic cigarettes (e-cigarettes) are often promoted to assist with cigarette smoking cessation. In 2016–2017, the relationship between e-cigarette use and having stopped smoking among ever (current and former) smokers was assessed in the European Union and Great Britain by itself.
Methods:
Cross-sectional logistic regression of the association between being a former smoker and e-cigarette use was applied to the 2014 Eurobarometer survey of 28 European Union countries controlling for demographics.
Results:
Among all ever smokers, any regular ever use of nicotine e-cigarettes was associated with
lower odds of being a former smoker (unadjusted OR¼0.34, 95% CI¼0.26, 0.43, AOR¼0.43, 95% CI¼0.32, 0.58) compared with smokers who had never used e-cigarettes. In unadjusted models, daily use (OR¼0.42, 95% CI¼0.31, 0.56); occasional use (OR¼0.25, 95% CI¼0.18, 0.35); and experimentation (OR¼0.24, 95% CI¼0.19, 0.30) of nicotine e-cigarettes were associated with lower odds of being a former smoker compared with having never used nicotine-containing e-cigarettes. Comparable results were found in adjusted models. Results were similar in Great Britain alone. Among current smokers, daily cigarette consumption was 15.6 cigarettes/day (95% CI¼14.5, 16.7) among those who also used e-cigarettes versus 14.4 cigarettes/day (95% CI¼13.4, 15.4) for those who did not use them (po0.05).
Conclusions:
These results that e-cigarettes are associated with inhibiting rather than assisting in smoking cessation. On the population level, the net effect of the entry of e-cigarettes into the European Union (and Great Britain) is associated with depressed smoking cessation of conventional cigarettes.
