Impact of e-cigarette use on smoking combustible cigarettes: Evidence from a large national survey
Methods: Multivariate regression analyses were conducted using individual-level data from a large (N=6,607) national survey of cigarette and e-cigarette users, to examine the impact of e-cigarette use on combustible cigarettes by looking at cigarette consumption per day as well as quitting intentions and attempts among current cigarette smokers.
Results: Among daily smokers, those who dual-used e-cigarettes with combustible cigarettes on a daily basis smoked 2 fewer cigarettes per day than those daily smokers who did not dual-use or only used e-cigarette on a non-daily basis. Cigarette consumption did not differ among “some day” smokers, regardless of e-cigarette use status. Compared with smokers who did not use e-cigarettes, daily and some day e-cigarette users were more likely to have intentions to quit and to have made quit attempts in the 3 months prior to the survey.
Conclusion: E-cigarette use was found to be associated with having quitting intentions and having made quit attempts. E-cigarette use also was found to reduce cigarette consumption among daily users; however, the reduction in cigarette consumption was small (2 cigarettes per day), and thus unlikely leading to substantial harm reduction benefits.
