  Abstract: OBJECTIVE: To determine if cigarette   mentholation is associated with the frequency of smoking and with   quitting, and whether mentholation explains racial differences in   these two smoking behaviours. DESIGN: Cross sectional analysis of   case-control data on smoking and lung cancer. SUBJECTS: Limited   to 19 545 current and former cigarette smokers. MAIN OUTCOME   MEASURES: Smoking > 20 cigarettes per day (cpd) versus < or   = 20 cpd, and continued smoking versus quit smoking. RESULTS:   Among blacks, the prevalence odds ratio (POR) of heavy smoking   (> or = 21 cpd) associated with mentholated cigarettes versus   non-mentholated cigarettes was 0.7 (95% confidence interval (CI)   0.5 to 0.9) in current smokers and 0.6 (95% CI 0.4 to 0.9) in   former smokers. Among whites, the corresponding POR were 0.9 (95%   CI 0.8 to 1.0) and 0.9 (95% CI 0.8 to 1.0). Blacks were less   likely to have been heavy smokers than whites, but the difference   was unrelated to cigarette mentholation. The POR of continued   smoking versus quitting, associated with mentholated cigarettes   was 1.1 (95% CI 1.0 to 1.2) for both blacks and whites.   CONCLUSION: Smoking > 20 cpd was independently associated with   white race. Among blacks, smoking < or = 20 cpd was   independently associated with mentholated cigarettes. The risk of   quitting was not associated with cigarette menthol flavour.
