Introduction While many studies have examined the association between e-cigarette use and smoking cessation, fewer have considered the impact of e-cigarette flavors on cessation outcomes. This study extends previous studies by examining the effects of e-cigarette use and e-cigarette flavors on quit attempts and quit success of smoking. Methods We used data from the 2018-2019 Tobacco Use Supplement-Current Population Survey (TUS-CPS) survey. Multivariate logistic regression analyses were used to investigate the associations between flavored e-cigarette use with quit attempts and quit success of smoking among individuals who smoked 12 months ago. Two current e-cigarette use definitions were used in these logistic regression analyses; currently use every day or some days vs. 20+ days in the past 30-days. Results Compared to those not using e-cigarettes, current everyday or someday e-cigarette use with all non-tobacco flavors had an adjusted odds ratio (AOR) of 2.9 (95% CI: 2.4-3.5) for quit attempts and 1.7 (95% CI: 1.3-2.2) for quit success. 20+ days e-cigarette use with flavors had stronger associations with quit attempts (AOR=4.2, 95% CI: 3.1-5.5) and quit success (AOR=4.0, 95% CI: 2.9-5.4). E-cigarette users with non-tobacco flavors were more likely to succeed in quitting compared to those exclusively using non-flavored or tobacco-flavored e-cigarettes. Menthol/mint flavor users had slightly higher odds of quit attempts and success than users of other non-tobacco flavors. Conclusions E-cigarette use is positively associated with both making a smoking quit attempt and quit success. Those using flavored e-cigarettes, particularly menthol/mint, are more likely to quit successfully. Implications E-cigarette use is positively associated with both making a quit attempt and quit success, and those using flavored e-cigarettes are more likely to successfully quit smoking, with no statistically significant differences between use of menthol or mint flavored e-cigarettes versus use of other non-tobacco flavored products. This suggests that the potential for e-cigarettes to help people who currently smoke quit could be maintained with the availability of menthol or mint flavored e-cigarettes, even if other non-tobacco flavored products, which are associated with e-cigarette use among youth, were removed from the market.

Introduction Cigar use is common in the United States; however, knowledge about trends and longitudinal patterns of premium and non-premium cigar use is limited. We analyzed cross-sectional and transition patterns of cigar use in the United States by cigar type, age, race/ethnicity, and socioeconomic status. Aims and Methods Using data from the Population Assessment of Tobacco and Health (PATH) Study, we compared characteristics of cigar users by Wave (1–5) and type; premium versus non-premium traditional cigars, cigarillos, and filtered cigars. We then calculated longitudinal transition rates of cigar and cigarette use between PATH Study Waves and longitudinal trajectories across all five Waves. Results Premium cigars were predominantly used by males, non-Hispanic White individuals, and those with high educational attainment. Premium cigar use was mostly non-daily and less likely to be dual with cigarettes or other cigar types. About three-quarters of exclusive premium cigar users remained so after one year. However, dual-use of premium cigars with either other cigar types or cigarettes was transient. Those who smoked premium cigars fairly regularly for at least one year were more likely to be exclusive premium cigar users or have dropped combustible tobacco product use by Wave 5. Conclusions Cigar use patterns vary significantly by cigar type. Premium cigar users have distinctive characteristics compared to other cigar-type users. When studying cigar use and related health outcomes, it is critical to distinguish cigar type. Implications Continuous monitoring of longitudinal use patterns of premium and non-premium cigar use and their co-use and transitions to other tobacco products, including inhalation and a more precise measure of the intensity of use, is essential for a better assessment of their health implications.

Two current e-cigarette use definitions were considered; currently use every day or some days vs. 20+ days in the past 30-days. Results: Compared to those not using e-cigarettes, current every day or some days e-cigarette use with all non-tobacco flavors had an adjusted odds ratio (AOR) of 2.9 (95% CI: 2.4-3.5) for quit attempts and 1.7 (95% CI: 1.3-2.2) for quit success. 20+ days e-cigarette use with flavors had stronger associations with quit attempts (AOR=4.2, 95% CI: 3.1-5.5) and quit success (AOR=4.0, 95% CI: 2.9-5.4).
