Few studies assess whether electronic cigarette (e-cigarette) device characteristics or flavors impact longitudinal patterns of cigarette and e-cigarette use. We examined data from waves 2–4 of the Population Assessment of Tobacco and Health study (2014–2018). Among adult (≥18y) current e-cigarette users at wave 2 who were current smokers (dual users; n=1,759) and former smokers (exclusive e-cigarette users; n=470), we classified participants into four use patterns at wave 3 (~12-months later) and wave 4 (~24 months later): (1) dual use of e-cigarettes and cigarettes; (2) exclusive cigarette smoking; (3) exclusive e-cigarette use; (4) non-use of both products. We used multinomial logistic regression to assess correlates of changing use patterns at 24 months, relative to no change, adjusting for socio-demographic factors. At 24 months, 26.5% of baseline exclusive e-cigarette users, and 9% of baseline dual users, abstained from both vaping and smoking. Participants who vaped non-tobacco flavors (vs. tobacco flavors), and used refillable tank or modifiable devices (vs. disposable, cartridges, and other devices) were less likely to transition to non-use of both products, and to exclusive cigarette smoking. Baseline daily vaping (vs. non-daily) was positively associated with exclusive e-cigarette use at 24 months for baseline daily cigarette smokers, but negatively associated with exclusive e-cigarette use and non-use of both products at 24 months for baseline non-daily smokers. Non-tobacco flavors, daily vaping, and modifiable e-cigarette devices may help some smokers abstain from cigarette smoking via transitioning to exclusive e-cigarette use, but are also associated with ongoing exclusive e-cigarette use.
