This study aimed to identify factors associated with e-cigarette quitting interest and quitting behaviors in exclusive, long-term e-cigarette users. These e-cigarette users were surveyed in January 2017 (baseline) and June 2019 (follow-up), with an average follow-up period of 2.4 years. At baseline, the sample had been e-cigarette users for an average of 5.6 years. Among the 221 participants, 205 (92.8%) did not intend to quit using e-cigarettes at baseline. At follow-up, 196 (88.7%) continued exclusive e-cigarette use, 17 (7.7%) quit e-cigarettes, 8 (3.6%) became dual users, and none became exclusive smokers. At baseline, 16 users intended to quit e-cigarettes, 2 (12.5%) of whom quit at follow-up. Predictors of quitting e-cigarettes included no previous cigarette smoking (β = -3.7, OR = 0.021, p < .01), lower Penn State Electronic Cigarette Dependence Index score (β = -0.21, OR = 0.81, p = .011), and lower number of devices used per day (β = -1.9, OR = 0.15, p = .015). Intending to quit e-cigarettes at baseline was not predictive of quitting at follow-up. At follow-up, 57 (25.8%) had tried to quit in the past. Overall predictors of trying to quit included interest in quitting at baseline (β = 1.7, OR = 5.3, p < .01) and using a drip-fed atomizer (β = 1.0, OR = 2.7, p = .022). These results suggest that long-term exclusive e-cigarette users generally have little interest in stopping e-cigarette use, and that type of device used, smoking history, e-cigarette dependence, number of devices used, and intention to quit are associated with e-cigarette quitting behaviors.Addictive behaviorsQuitting electronic cigarettes: Factors associated with quitting and quit attempts in long-term users.PMC9112866P50 DA036107R01 DA048428U01 DA045517Foulds JSobieski EYingst JfalseQuitting electronic cigarettes: Factors associated with quitting and quit attempts in long-term users.Some electronic cigarette (e-cigarette) users are interested in quitting e-cigarette use, though few studies have assessed what factors contribute to this interest.
