Background: It has been hypothesized that menthol in cigarettes increases dependence. Several studies suggest that menthol and non-menthol smokers have similar or lower levels of dependence, but those studies are not without limitations. The Heaviness of Smoking Index (HSI) is a widely accepted, validated measure of cigarette dependence.
Objectives: This report aims to provide further evidence regarding dependence among menthol and non-menthol smokers, as indicated by daily smoking and as measured by the HSI.
Methods: Survey data from 27,131 adult smokers were analyzed to compare the percent of menthol and non-menthol smokers who are daily smokers, and the percentage who are low or high HSI dependence. Logistic regressions were also conducted to determine if menthol use predicts daily smoking, and low or high dependence after controlling for demographic differences.
Results: Comparisons among weighted samples of adult smokers demonstrate that menthol smokers were consistently more likely to be non-daily smokers, more likely to be in the low dependence category, and less likely to be in the high dependence category on the HSI as compared to non-menthol smokers. Logistic regression confirmed that when controlling for age, gender, race/ethnicity, and education, relative to non-menthol smokers, menthol smokers had no difference in odds of being in the low dependence HSI category and significantly lower odds of being a daily smoker, and of being in the high dependence category.
Conclusions: These analyses support the conclusion that, based on the HSI, menthol smokers are not more cigarette dependent than non-menthol smokers, and may be dependent.

Assessment of Abuse Liability and Nicotine Pharmacokinetics of glo Heated Tobacco Products in a Randomized, Crossover Study.
Eur J Drug Metab Pharmacokinet
November 2024
RAI Services Company, 401 N. Main Street, Winston-Salem, NC, 27101, USA.
Article Synopsis
- Heated tobacco products (HTPs) are considered potentially less harmful alternatives to traditional cigarettes, as they produce fewer toxicants.
- A clinical study assessed the abuse liability (AL) of glo HTPs in two modes by comparing nicotine uptake and subjective effects to usual brand cigarettes and nicotine gum among healthy adult smokers.
- Results indicated that glo HTPs led to significantly lower nicotine uptake and levels compared to regular cigarettes, suggesting they might be safer options for smokers.

Effects of cigarette package colors and warning labels on marlboro smokers' risk beliefs, product appraisals, and smoking behavior: a randomized trial.

Department of Psychiatry and Tobacco Center of Regulatory Science, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.
Objective: Plain packaging and graphic warning labels are two regulatory strategies that may impact cigarette risk beliefs and reduce consumption, but data are needed to better understand how smokers respond to such regulations.
Methods: Adult, daily, Marlboro non-menthol smokers (Red [n = 141] or Gold [n = 43]) completed a mixed factorial randomized trial. Participants smoked their usual cigarettes during baseline (5-days) and were randomized to receive cigarette packs with a warning label manipulation (graphic vs.
Improving Prediction of Tobacco Use Over Time: Findings from Waves 1-4 of the Population Assessment of Tobacco and Health Study.
Nicotine Tob Res

Department of Health Policy and Management, Gillings School of Global Public Health, University of North Carolina, Chapel Hill, NC, USA.
Introduction: First-order Markov models assume future tobacco use behavior is dependent on current tobacco use and are often used to characterize patterns of tobacco use over time. Higher-order Markov models that assume future behavior is dependent on current and prior tobacco use may better estimate patterns of tobacco use.
Aims And Methods: This study compared Markov models of different orders to examine whether incorporating information about tobacco use history improves model estimation of tobacco use and estimated tobacco use transition probabilities.
Illicit purchasing and use of flavour accessories after the European Union menthol cigarette ban: findings from the 2020-21 ITC Netherlands Surveys.

Department of Primary Care and Public Health, School of Public Health, Imperial College London, London, UK.
Background: The 2020 European Union (EU) menthol cigarette ban increased quitting among pre-ban menthol smokers in the Netherlands, but some reported continuing to smoke menthol cigarettes. This study examined three possible explanations for post-ban menthol use-(i) illicit purchasing, (ii) use of flavour accessories and (iii) use of non-menthol replacement brands marketed for menthol smokers.
Methods: Data were from the ITC Netherlands Cohort Surveys among adult smokers before the menthol ban (Wave 1: February-March 2020, N = 2067) and after the ban (Wave 2: September-November 2020, N = 1752; Wave 3: June-July 2021, N = 1721).
