Associations Between
E-cigarette Use and E-cigarette Flavors with Cigarette Smoking Quit Attempts
and Quit Success: Evidence from a U.S. Large, Nationally Representative
2018-2019 Survey.
Nicotine Tob Res. 2023 Feb 9;25(3):541-552. doi: 10.1093/ntr/ntac241. PMID:

Introduction. Although
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.
Aims and 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 versus 20+ days in
the past 30 days.
Results. Compared
to those not using e-cigarettes, current every day or someday e-cigarette use
with all nontobacco flavors had an adjusted odds ratio (AOR) of 2.9 (95% CI:
2.4 to 3.5) for quit attempts and 1.7 (95% CI: 1.3 to 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 to 5.5) and quit success (AOR = 4.0, 95% CI: 2.9
to 5.4). E-cigarette users with nontobacco flavors were more likely to succeed
in quitting compared to those exclusively using non-flavored or
tobacco-flavored e-cigarettes. Menthol or mint flavor users had slightly higher
odds of quit attempts and success than users of other nontobacco flavors.
Conclusions. E-cigarette
use is positively associated with both making smoking quit attempts and quit
success. Those using flavored e-cigarettes, particularly menthol or 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 the use of menthol
or mint-flavored e-cigarettes versus the use of other nontobacco 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 nontobacco flavored products, which
are associated with e-cigarette use among youth, were removed from the market.
