  "abstract": "Introduction\n\nA substantial proportion of people who smoke cigarettes have used e-cigarettes to reduce or quit smoking. However, there are many transitions to either using both e-cigarettes and cigarettes, or returning to smoking cigarettes exclusively. Limited research has focused on this population. This study aims to examine whether e-cigarette characteristics, use patterns, and perceptions of e-cigarettes predict e-cigarette discontinuation among people who smoke cigarettes.Methods\n\nData were drawn from the Adult Consumers of Tobacco Study, a nationally representative cross-sectional study conducted in 2023. A total of 2644 US adults completed an online questionnaire. We conducted a secondary analysis of 1507 participants who currently smoked cigarettes and had previously used e-cigarettes or were currently using e-cigarettes at the time of the survey.Results\n\nUse of two flavors (adjusted odds ratio, AOR=0.53; 95% CI: 0.37-0.75) and more than two flavors (AOR=0.42; 95% CI: 0.29-0.62) was associated with lower odds of e-cigarette discontinuation. Compared with tobacco flavor use, use of fruit flavor (AOR=0.58; 95% CI: 0.42-0.80) and candy, dessert, chocolate, or other sweet flavors (AOR=0.57; 95% CI: 0.41-0.79) was also associated with lower odds of e-cigarette discontinuation. Additionally, greater perceived absolute harm of e-cigarettes (somewhat vs not at all/slight harmful, AOR=2.00; 95% CI: 1.20-3.35; very/extremely vs not at all/slight harmful, AOR=4.25; 95% CI: 2.60-6.99) and greater perceived relative harm of e-cigarettes compared with conventional cigarettes (about the same level of harm vs much less/less harmful, AOR=2.60; 95% CI: 1.86-3.66, more/much more harmful vs much less/less harmful, AOR=3.45; 95% CI: 2.22-5.46) were associated with higher odds of e-cigarette discontinuation.Conclusions\n\nFlavors were associated with e-cigarette continuation, and perceptions of e-cigarette harm were associated with e-cigarette discontinuation among people who smoke cigarettes. Additional studies are needed to provide stronger evidence regarding these associations.",
