Real-world vaping experiences and smoking cessation among cigarette smoking adults

Abstract

Introduction: E-cigarettes may have the potential to be an effective cessation aid for some cigarette smokers. However, the extent to which smokers' experiences using e-cigarettes (vaping) to quit smoking impact their cessation outcomes is unclear. In this cross-sectional survey study, we develop a multidimensional measure of vaping experiences in adults who quit smoking by vaping and test its association with perceived success in smoking cessation.

Methods: In 2019, recruitment invitations were emailed to adult past-year smokers who had accessed cessation services across Ontario, Canada. Respondents who tried vaping to quit smoking in the past year completed a detailed online survey. Factor analysis was performed on ratings of 45 vaping experiences items to identify dimensions of vaping experiences. Factor scores were entered into logistic regressions to test if vaping experiences dimensions had differential impact on perceived success in smoking cessation.

Results: Of the 889 participants, 56.0% were female, 81.1% were Caucasian, and the mean age was 37.7 ± 11.9 years. Twenty percent (19.6%) reported having successfully quit smoking by vaping in the past year. Among the six vaping experiences factors, better experiences in five factors-Relationships, Flexibility of Vaping, Side Effects, Vaping Devices, and Sensory Functions-were each independently and positively associated with improved odds of successful quitting. Notably, Relationships [OR = 2.01, 95% CI: 1.61-2.64] and Side Effects [OR = 1.95; 95% CI 1.54-2.29] were the strongest correlates of perceived success in smoking cessation.

Conclusions: These findings indicate an opportunity to increase cessation rates by improving the experiences of smokers who vape to quit smoking.
