Studies have assessed switching away from cigarettes among adult smokers who use electronic nicotine delivery systems (ENDS), but there is little data assessing differences in likelihood of switching or ENDS use characteristics by menthol smoking. Adult (age ≥ 21) established smokers who purchased a JUUL Starter Kit (N = 15,036) completed baseline and 1-, 2-, 3-, 6-, 9- and 12-month assessments. Switching (no past-30-day cigarette smoking) and flavor use were assessed at each follow-up. Repeated-measure logistic regression models evaluated association of menthol smoking and switching across 1 year. Across the 6 follow-ups, more menthol smokers primarily used Menthol/Mint-flavored JUULpods (53.8%) than nonmenthol smokers (22.9%). Only 6.4% of menthol smokers primarily used Tobacco flavors (vs. 25.9% of nonmenthol smokers). Across all follow-ups menthol smokers (41.2% of sample) were more likely to switch than nonmenthol smokers (42.6% vs. 38.8%: OR [95% CI] = 1.17 [1.11, 1.23]); this association remained significant after adjustment for sociodemographic, smoking and JUUL use covariates (aOR [95% CI] = 1.13 [1.05, 1.21]). Nonmenthol smokers, but not menthol smokers, were significantly more likely to switch when primarily using Menthol/Mint-flavored (vs. Tobacco-flavored) JUULpods (aOR [95% CI] = 1.14 [1.04, 1.25]). Differences in baseline smoking characteristics between menthol and nonmenthol smokers were small in magnitude. Adult menthol (vs. nonmenthol) smokers using JUUL were more likely to switch. More than twice as many menthol (vs. nonmenthol) smokers primarily used Menthol/Mint-flavor JUULpods; few menthol smokers used tobacco flavors. Given these pronounced differences in flavor preferences, availability of ENDS in menthol flavors may be particularly important for menthol smokers, but may also benefit some nonmenthol smokers. •Adult menthol and nonmenthol smokers who purchased JUUL were followed for 1-year.•Menthol (vs. nonmenthol) smokers had higher rates of switching away from cigarettes.•Over twice as many menthol (vs. nonmenthol) smokers used Menthol/Mint JUULpods.•Four-times as many nonmenthol (vs. menthol) smokers used tobacco-flavored JUULpods.•Menthol-flavored ENDS may be particularly important for menthol smokers.
