RESUMO
PURPOSE: The objective of this article is to examine the factors associated with smoking of flavor capsule cigarettes in Chile, where the popularity of these products has increased dramatically, a trend increasingly observed across the world. METHODS: A representative poll of 851 smokers in Metropolitan Santiago de Chile, which comprises 40% of the country's total population, was implemented in mid-2017. Smokers were given a questionnaire that collected socio-demographic information and information on smoking patterns. Four discrete-choice models were estimated on the decision to smoke flavor capsule cigarettes to better understand the statistical relationships between traits of smokers and the consumption of flavor capsule cigarettes. RESULTS: The results of these models show that each year less in a smoker's age increases the likelihood of preferring flavor capsule cigarettes by, on average, between 0.8 and 0.9 percentage points. If the smoker is a woman, the likelihood of preferring flavor capsule cigarettes increases between 13.4 and 13.5 percentage points. Results also reveal a positive relationship between the price paid and the consumption of flavor capsule cigarettes, indicating that these cigarettes tend to be more expensive. There is no statistical relationship between participation in the labor market and smoking these products. CONCLUSIONS: Chile has the world's highest prevalence of flavor capsule cigarette smoking, which is concentrated among young people (25 years and younger) and females. No relationship between socioeconomic status and use of these products is found, though there are indications that such relationship may exist, as they were at the time of study 14% more expensive, on average, than conventional non-flavored cigarettes. As in most countries, the tobacco industry appears to be deliberately promoting these products with the goal of halting or slowing the decline in cigarette consumption in Chile. Thus, to reduce cigarette consumption (especially among youth), restricting or forbidding cigarette flavorings of all types, including flavor capsules, would be an effective strategy.

OBJECTIVES: Cuba is a tobacco-producing country that has been economically isolated as a consequence of an embargo imposed by the USA. It has also experienced a severe economic depression in the 1990s after the withdrawal of support by the former Soviet Union. These characteristics provide a unique opportunity to study the relation between large changes in economic activity, cigarette price and demand for cigarettes in a relatively isolated socialist economy. STUDY DESIGN: This is an observational epidemiological study. METHODS: Data were obtained on the annual price of a packet of cigarettes and the mean number of cigarettes consumed per adult living in Cuba from 1980 to 2014. Descriptive and regression analysis were used to explore the relationship between cigarette consumption and price in Cuba. RESULTS: In 1980, the mean price of a packet of cigarettes was 1.53 Cuban peso (CUP) in 1997 prices and the mean annual per capita consumption was 2237 cigarettes. In 2014, the mean price had increased to 5.57 CUP (1997 prices) per packet of cigarettes, and consumption had fallen to 1527 cigarettes per capita. There were significant negative associations between annual cigarette consumption and both price and living through an economic depression. The elasticity was approximately -0.31 with price, and living through an economic depression was also associated with lower consumption of cigarettes (a reduction of 9%, 95% confidence intervals -0.18 to -0.001). CONCLUSIONS: Higher cigarette pricing, along with other public health interventions, are required to protect the national population from the adverse effects of tobacco smoke exposure.

BACKGROUND: Price affects the demand for cigarettes, indicating that smokers, perhaps especially lower income smokers, may choose low nicotine cigarettes (LNC) if they were commercially available and cost less than fully nicotinized conventional cigarettes. The present study tests the hypothesis that smokers will prefer purchasing LNCs at a lower price point than conventional cigarettes given a fixed budget. METHOD: A laboratory-based, within-subject, 3 (nicotine level) × 3 (price) factorial design provided smokers opportunities to purchase standard (0.7 per mg tobacco), moderately reduced (0.3 mg), and very low-nicotine (0.03 mg). Spectrum research cigarettes according to an escalating price structure (low-nicotine costing the least, high-nicotine costing the most) given a fixed, laboratory-provided "income." Participants were 20 overnight-abstinent smokers who previously smoked and rated each of the three cigarettes. RESULTS: Overall, smokers rated LNCs as less satisfying compared with standard nicotine cigarettes (SNC), t(18) = -5.40, p < .001. In the free-choice session, subjects were more likely to choose LNC that cost less compared with SNC that cost more, even after an 8-hour abstinence period, F(2, 19) = 4.32, p = .03. Those selecting LNC or moderate nicotine cigarettes after abstinence smoked more cigarettes per day, t(17) = 2.40, p = .03 and had higher dependence scores on the HONC, t(18) = 2.21, p = .04 that those selecting SNC. CONCLUSION: The results indicate that smokers' response to price points when purchasing cigarettes may extend to LNC if these were commercially available. Differential cigarette prices based on nicotine content may result in voluntary selection of less addicting products. IMPLICATIONS: The Food and Drug Administration has proposed a rule that would reduce nicotine content in commercially available cigarettes. However, it is not known how smokers may respond in an environment where products of differing nicotine content and of differing prices are available. This study demonstrates that price may be an important factor that could lead smokers to select reduced nicotine products voluntarily, even if those products are rated as inferior or less satisfying.

OBJECTIVES: To estimate the proportions of illicit cigarette consumption in Brazil from 2012 to 2016, a period of sharp increases in cigarette taxes. METHODS: We used an approach based on legal sales provided by the Secretariat of Federal Revenues and self-reported consumption data from an annually conducted telephone survey (VIGITEL) to estimate the changes over time in illegal cigarette use in Brazil. For that purpose, we also used available information on the proportion of illegal cigarette consumption from a nationwide household survey conducted in 2013 to calculate a constant proportion of underreporting from VIGITEL in relation to total consumption and sales in Brazil. RESULTS: There was an increase in the estimated proportion of illicit cigarette use from 2012 to 2013 (from 28.6% to 32.3%), then a decrease from 2013 to 2014 (32.3% to 28.8%), and then a sustained trend of increase from 2014 to 2016 (28.8% to 42.8%). CONCLUSIONS: Novel and feasible approaches to estimate changes over time in the illegal market are important for helping the effective implementation of tobacco excise tax policy.

Introduction: Studies testing novel tobacco products often provide participants with free product and assess consumption. Some, but not all, studies find that providing free cigarettes increases smoking. We tested changes in smoking when free cigarettes were provided to nondaily, intermittent smokers, who constitute one-third of US adult smokers. Methods: Cigarette consumption was assessed by Time-Line Follow-Back in 235 intermittent smokers for two 2-week periods: when providing their own cigarettes and when provided own-brand cigarettes for free. Smoking topography and carbon monoxide boost were assessed for one cigarette at the end of each period. Results: Cigarette consumption increased significantly, by 66% (from 1.98 to 3.28 cigarettes per day), when cigarettes were available for free; both the number of days the subjects smoked and the number of cigarettes on those days increased. The increases were significantly greater among African Americans, those Fagerström Tobacco Nicotine Dependence scores >0, those with incomes less than US $25,000 per year, those who engaged in greater conscious restraint of smoking, and for smokers of menthol cigarettes, or "longs." Smoking intensity (smoke volume, by topography) and carbon monoxide boost decreased significantly when cigarettes were provided for free. Conclusions: Providing intermittent smokers with free cigarettes substantially increased their smoking while decreasing smoking intensity. The increases in smoking varied according to multiple individual and cigarette-type differences. These phenomena may complicate interpretation of studies that compare consumption of a free test product with cigarette consumption or constituent exposure when smokers are providing their own cigarettes. They also suggest that cigarette cost and variations in low-level dependence and in smoking restraint are factors in nondaily smoking. Implications: The study shows that providing nondaily smokers with free cigarettes increases cigarette consumption, but does differentially for different subgroups and cigarette types, while also decreasing smoking intensity. This suggests the value of using free-cigarette baseline data in studies where interventions provide free cigarettes.

INTRODUCTION: Previous evidence linked low socioeconomic status with higher smoking prevalence. Our objective was to assess the strength of this association in the world population, updating a previous work. METHODS: Systematic review and meta-analysis of observational studies. Subgroup analyses included continents, WHO regions, country mortality levels, gender, age, risk of bias, and study publication date. Independent reviewers selected studies, assessed potential bias and extracted data. We searched MEDLINE, EMBASE, CENTRAL, SOCINDEX, AFRICAN INDEX MEDICUS, and LILACS, and other sources from 1989 to 2013 reporting direct measurements of income and current cigarette smoking. RESULTS: We retrieved 13,583 articles and included 93 for meta-analysis. Median smoking prevalence was 17.8% (range 3-70%). Lower income was consistently associated with higher smoking prevalence (odds ratio [OR]: 1.45; 95% confidence interval [CI]: 1.35-1.56). This association was statistically significant in the subgroup analysis by WHO regions for the Americas (OR: 1.54; 95% CI: 1.42-1.68), South East Asia (OR: 1.53; 95% CI: 1.10-2.00), Europe (OR: 1.45; 95% CI: 1.29-1.63), and Western Pacific (OR: 1.32; 95% CI: 1.02-1.72), and in studies conducted during 1990s (OR: 1.42; 95% CI: 1.24-1.62) and 2000s (OR: 1.48; 95%CI: 1.30-1.64). Likewise, it was noted in low-mortality countries (OR: 1.48; 95% CI: 1.37-1.60) and for both genders. Prevalence was highest in the lowest income levels compared to the middle (OR: 1.69; 95% CI: 1.49-1.92), followed by the middle level compared to the highest (OR: 1.31; 95% CI: 1.20-1.43). CONCLUSIONS: Our results show that current cigarette smoking was significantly associated with lower income worldwide and across subgroups, suggesting a dose-response relationship. IMPLICATIONS: This unique updated systematic review shows a consistent inverse dose-response relationship between cigarette smoking and income level, present among most geographical areas and country characteristics. Public health measures should take into account this potential inequity and consider special efforts directed to disadvantaged populations.

BACKGROUND: Brazil experienced a large decline in smoking prevalence between 2008 and 2013. Tax rate increases since 2007 and a new tobacco tax structure in 2012 may have played an important role in this decline. However, continuous tax rate increases pushed up cigarette prices over personal income growth and, therefore, some consumers, especially lower income individuals, may have migrated to cheaper illicit cigarettes. OBJECTIVE: To use tobacco surveillance data to estimate the size of illicit tobacco consumption before and after excise tax increases. METHODS: We defined a threshold price and compared it with purchasing prices obtained from two representative surveys conducted in 2008 and 2013 to estimate the proportion of illicit cigarette use among daily smokers. Generalised linear model was specified to understand whether the absolute difference in proportions over time differed by sociodemographic groups and consumption levels. Our findings were validated using an alternative method. RESULTS: Total proportion of illicit daily consumption increased from 16.6% to 31.1% between 2008 and 2013. We observed a pattern of unadjusted absolute decreases in cigarette smoking prevalence and increases in the proportion of illicit consumption, irrespective of gender, age, educational level, area of residence and amount of cigarettes consumed. CONCLUSIONS: The strategy of raising taxes has increased government revenues, reduced smoking prevalence and resulted in an increased illicit trade. Surveillance data can be used to provide information on illicit tobacco trade to help in the implementation of WHO Framework Convention on Tobacco Control (FCTC) article 15 and the FCTC Protocol to Eliminate Illicit Trade in Tobacco Products.
