ABSTRACT Menthol cigarette smokers may find it harder to quit smoking than smokers of nonmenthol cigarettes.
We conducted a systematic review of published studies examining the association between menthol cigarette smoking and cessation. Electronic databases and reference lists were searched to identify studies published through May 2010, and results were tabulated.
Ten studies were located that reported cessation outcomes for menthol and nonmenthol smokers. Half of the studies found evidence that menthol smoking is associated with lower odds of cessation, while the other half found no such effects. The pattern of results in these studies suggest that the association between smoking menthol cigarettes and difficulty quitting is stronger in (a) racial/ethnic minority populations, (b) younger smokers, and (c) studies carried out after 1999. This pattern is consistent with an effect that relies on menthol to facilitate increased nicotine intake from fewer cigarettes where economic pressure restricts the number of cigarettes smokers can afford to purchase.
There is growing evidence that certain subgroups of smokers find it harder to quit menthol versus nonmenthol cigarettes. There is a need for additional research, and particularly for studies including adequately powered and diverse samples of menthol and nonmenthol smokers, with reliable measurement of cigarette brands, socioeconomic status, and biomarkers of nicotine intake.

    ABSTRACT: AimsTo assess the relations of menthol cigarette use with measures of cessation success in a large comparative effectiveness trial (CET). DesignParticipants were randomized to one of six medication treatment conditions in a randomized double-blind, placebo-controlled clinical trial. All participants received six individual counseling sessions. SettingCommunity-based smokers in two communities in Wisconsin, USA. ParticipantsA total of 1504 adult smokers who smoked at least 10 cigarettes per day during the past 6 months and reported being motivated to quit smoking. The analysis sample comprised 1439 participants: 814 white non-menthol smokers, 439 white menthol smokers and 186 African American (AA) menthol smokers. There were too few AA non-menthol smokers (n=16) to be included in the analyses. InterventionsNicotine lozenge, nicotine patch, bupropion sustained release, nicotine patch+nicotine lozenge, bupropion+nicotine lozenge and placebo. MeasurementsBiochemically confirmed 7-day point-prevalence abstinence assessed at 4, 8 and 26 weeks post-quit. FindingsIn longitudinal abstinence analyses (generalized estimating equations) controlling for cessation treatment, menthol smoking was associated with reduced likelihood of smoking cessation success relative to non-menthol smoking [model-based estimates of abstinence=31 versus 38%, respectively; odds ratio (OR)=0.71, 95% confidence interval (CI)=0.59, 0.86]. In addition, among menthol smokers, AA women were at especially high risk of cessation failure relative to white women (estimated abstinence=17 versus 35%, respectively; OR=2.63, 95% CI=1.75, 3.96; estimated abstinence rates for AA males and white males were both 30%, OR=1.06, 95% CI=0.60, 1.66). Conclusion In the United States, smoking menthol cigarettes appears to be associated with reduced cessation success compared with non-menthol smoking, especially in African American females.

    ABSTRACT: Nimpitakpong P. and Dhippayom T. Menthol cigarettes: Tobacco control policy in Thailand. J Pub. Health Dev. 2012; 10(2): 72-85 Thailand has more than 12.5 million smokers (8 million smoke cigarettes). About 19% of cigarette smokers smoke menthol cigarettes. This article reviews previous research related to menthol cigarettes in order to improve public health policy regarding tobacco control. The review shows that menthol cigarette smokers' risk of developing diseases was equivalent to that of those who smoke non-menthol cigarettes. However, menthol cigarette smokers believe that menthol had medicinal benefits and therefore were less harmful than normal cigarettes. The tobacco industry uses menthol cigarettes to target young and new smokers as well as those who intend to quit smoking. This strategy will either increase the number of smokers or not reduce the number of smokers as much as expected. The challenge for tobacco control policy in Thailand is to comply with the WHO Framework Convention for Tobacco Control by prohibiting the use on cigarette packs of the word "menthol" or other terms which could imply as a cooling property and to ban menthol cigarettes in Thailand.

    ABSTRACT: Nowadays the European Union faces a debate on the ban of sale of flavoured cigarettes. There is growing evidence that certain subgroups of smokers are more vulnerable to the use of flavoured cigarettes. However in some European countries, figures on the use of these cigarettes are still scarce. The aim of the study was to assess the prevalence of flavoured cigarettes use in Poland, and examine whether its use among adults varies by socio-demographic characteristics. Data on tobacco use including flavoured cigarettes and other characteristics were derived from the Global Adult Tobacco Survey (GATS). GATS is a cross-sectional, household survey implemented in Poland between 2009 and 2010. GATS provided data on a representative sample of 7,840 individuals covering 2,254 current smokers. Logistic regression model was used to obtain odds ratios (ORs) and 95% confidence interval (CI) of the selected socio-economic variables on the use of flavoured cigarettes. Among females the aromatized cigarettes use was 26.1% compared to 10.5% in males (OR = 2.3; 95% CI:1.62-3.2; p <= 0.001). Respondents aged 20-29 years had an increased likelihood of using flavoured cigarettes compared to subjects aged 60 years or older (OR = 2.7; 95% CI: 1.1-6.5; p <= 0.001). Respondents aware of negative health consequences of smoking had OR = 1.4 95% CI: 1.1-2.1 (p <= 0.05) of smoking aromatized cigarettes compared to those who were unaware. Participants who perceived some kinds of cigarettes less harmful than others were also more likely to use flavoured cigarettes compared to subjects who were convinced that all cigarettes are equally harmful (OR = 1.4; 95% CI: 1.1-1.8; p <= 0.01). High educational attainment, living in large cities, being non-economically active was also associated with use of flavoured cigarettes. Our results are consistent with majority of epidemiology studies on this topic to date and should be considered in the enactment of tobacco control legislation at the national as well as European levels. For combating tobacco epidemic, further efforts need to be made to prevent smoking uptake. Ban of flavoured cigarettes could considerably support achieving this goal.
