Background: A ban on the sale of menthol cigarettes in the United States is currently under consideration. A justification is that menthol cigarettes are harder to quit, particularly for African American smokers who use menthols much more frequently than White smokers, but epidemiologic data are limited.
Methods: In a cohort of 16 425 mostly low-income African American and White current cigarette smokers enrolled during 2002-2009, we computed smoking quit and reuptake rates at 3 follow-ups conducted means of 4.6, 7.7, and 11 years after entry. Generalized estimation equations were used to compute odds ratios (ORs) and 95% confidence intervals (CIs) for quitting and resuming smoking for menthol vs nonmenthol smokers adjusted for race, age, education, income, and smoking pack-years.
Results: Crude annual quit rates among current smokers were 4.3% for menthol and 4.5% for nonmenthol smokers, with adjusted odds ratios of quitting for menthol vs nonmenthol smokers of 1.01 (95% CI = 0.91 to 1.11) overall, 0.99 (95% CI = 0.87 to 1.12) among African American smokers, and 1.02 (95% CI = 0.88 to 1.20) among White smokers. Crude annual smoking reuptake rates were somewhat higher among menthol smokers (8.4%) than nonmenthol smokers (7.1%), with an adjusted odds ratio of 1.19 (95% CI = 0.97 to 1.47), but net quit rates remained similar (OR = 1.01, 95% CI = 0.90 to 1.13 overall; OR = 1.00, 95% CI = 0.86 to 1.15 among African American participants; and OR = 1.04, 95% CI = 0.87 to 1.24 among White participants).
Conclusions: This large-scale prospective survey revealed similar quit rates among menthol and nonmenthol smokers. Results contribute to policy discussions, especially if, as a meta-analysis suggests, lung cancer risk is higher for nonmenthol smokers and a ban leads menthol smokers to switch to nonmenthol cigarettes.
