Why Smoke Flavor Capsule Cigarettes? Preferences and Perceptions Among Adult Smokers in Mexico

Mint essential oil: A natural and effective agent for controlling house dust mites

Conventional methods of house dust mite control often involve chemical pesticides, raising concerns about their potential hazards. Mint essential oil presents a natural and eco-friendly alternative for managing house dust mite infestations. In this study, ten varieties of mint plants were cultivated, and their essential oils were extracted through steam distillation. The toxicity of these mint essential oils and their main compounds on adult house dust mites was assessed using contact+fumigant mortality bioassays and vapour-phase mortality bioassays. A repellent bioassay was also conducted to evaluate the repellent effects of mint oils and main compound on house dust mites. The toxicity of mint essential oils varied among the different varieties, with some demonstrating higher potency in eradicating house dust mites. Mint oils showed both acaricidal action and repellent effects on house dust mites, with certain varieties exhibiting stronger efficacy. Linalool as active compounds was identified as key contributors to the acaricidal properties of mint essential oil. Mint essential oil, particularly certain varieties rich in active compounds, shows promise as a natural and effective agent for controlling house dust mites. Its dual functionality in killing and repelling house dust mites, along with its environmentally friendly nature, make it a viable alternative to chemical pesticides for house dust mite management. Further research on the specific mechanisms of action and long-term effectiveness of mint essential oil in house dust mite control is warranted to explore its full potential as a sustainable pest management solution.

Use of flavor capsule cigarettes and their preliminary impact on smoking cessation in Mexico: an exploratory study

BACKGROUND

No study has assessed the impact of flavor capsule cigarettes (FCCs) on smoking cessation. Thus, the purpose of this exploratory study was to assess (1) the sociodemographic and smoking-related characteristics associated with using FCCs, and (2) the preliminary impact of FCCs on smoking cessation.

METHODS

This study is a secondary data analysis of a single-arm study with 100 individuals living in Mexico who smoked and received a smoking cessation mHealth intervention and pharmacotherapy support. The primary outcomes were self-reported and biochemically verified 7-day smoking abstinence at Month 3.

RESULTS

Just over one-third of participants (36%) used FCCs, with a preference for one capsule and menthol/mint flavor. Compared to participants who smoked non-FCCs, participants who smoked FCCs were (1) younger, (2) more likely to be women, and (3) more likely to smoke less than 10 cigarettes per day (CPD; all p's < 0.05). After controlling for all significant associations, age younger than 50 years old (AOR = 3.26, 95% CI 1.25-8.51) and being a woman (AOR = 3.62, 95% CI 1.41-9.35) were positively and independently associated with smoking FCCs. Treating those lost to follow-up as participants who continued smoking, 41.7% (15/36) of participants who smoked FCCs self-reported smoking abstinence at month 3 compared to 42.2% (27/64) of participants who smoked non-FCCs (p = 0.96). Furthermore, 33.3% (12/36) of participants who smoked FCCs were biochemically verified abstinent at Month 3 compared to 18.8% (12/64) of participants who smoked non-FCCs (p = 0.10).

CONCLUSIONS

Younger age and being a woman were associated with using FCCs. Self-reported smoking abstinence at Month 3 was comparable between participants who smoke FCCs and non-FCCs. However, biochemically verified abstinent at Month 3 was higher among participants who smoke FCCs compared to participants who smoke non-FCCs, although the difference was not statistically significant. Prospective and adequately powered comparisons must be made between individuals who smoke FCCs and non-FCCs to effectively assess differences in smoking abstinence, and the reasons for these differences.

The Use of Packaging Descriptors in a Rapidly Growing Market for Capsule Cigarettes: Evidence From Mexico

INTRODUCTION

The global market for capsule cigarettes has grown rapidly, especially in Latin America. This research examined the sales trends and patterns as well as packaging characteristics of capsule cigarette in Mexico in recent years.

METHODS

National data on cigarette sales in Mexico between October 2018 and September 2021 licensed from NielsenIQ were supplemented with cigarette pack pictures and Internet searches to determine whether characterizing flavor, concept flavor, and action descriptors were used. Market share in sales value and volume was calculated by capsule and flavor status, descriptors, price tier, manufacturer, pack size, and cigarette length for the whole time period and for each month. Number of unique brand variants was also examined.

RESULTS

Capsule cigarette sales totaled US$4.29 billion or 30.99 billion sticks during the assessed period, comprising 37.7% of the cigarette market share in sales value or 35.5% in sales volume. Over half of capsule cigarettes sold during this time period had concept flavor descriptors, 17.8% contained characterizing flavor descriptors, and 15.1% contained action descriptors that were suggestive of the interactive aspects of capsules. The monthly market share of capsule cigarette sales volume among all cigarette sales in Mexico increased steadily from 33.3% in October 2018 to 37.3% in September 2021.

CONCLUSIONS

The expanding capsule cigarette market in Mexico is concerning, given the product's associated misconceptions of reduced harm and greater appeal among youth. Findings underline the need for enhanced regulations to address the public health threat posed by capsule cigarettes.

IMPLICATIONS

Capsule cigarettes have a substantial market share in Mexico, with increasing popularity. Descriptors and other product characteristics such as cigarette length might be used to increase the appeal and target particular populations. Policy makers should consider banning capsules and flavors in cigarettes including descriptors or other indication in product presentation that could be perceived as denoting a taste, aroma, or sensation, and making the appearance and design of tobacco products more commensurate with the harm they cause by adopting plain and standardized packaging.

To use or not to use electronic cigarettes? Reasons for use, stopping use and their behavioural sequelae among Mexicans who smoke

INTRODUCTION

Reasons for using and stopping the use of e-cigarettes and their associations with transitions in nicotine product use are relatively unknown in countries with e-cigarette bans, such as Mexico.

METHODS

Data comes from an open cohort of people who smoke in Mexico, surveyed every 4 months from November 2018 to November 2021. Those who smoked and used e-cigarettes at time t (n=904 individuals, 1653 observations) were categorised at 4-month follow-up (t+1): (1) continued 'dual use', (2) exclusive smoking, (3) exclusive use of e-cigarettes or neither product. For people who formerly used e-cigarettes at time t (n=332 individuals, 372 observations), follow-up categories were: (1) continued exclusive smoking; (2) re-initiated e-cigarette use. Multinomial and logistic models regressed follow-up status (ref=status at time t) on reasons for using or stopping e-cigarette use, respectively, at time t, adjusting for covariates.

RESULTS

The most prevalent reasons for current e-cigarette use were 'they were less harmful to others' (40.5%) and 'enjoyable' (39.0%). Those who reported using e-cigarettes because they were less harmful to others (Adjusted Relative Risk Ratio (ARRR)=0.67), more enjoyable (ARRR=0.52), could help them to quit smoking (ARRR=0.65), or to control weight (ARRR=0.46) were less likely to return to exclusively smoking. Among people who formerly used e-cigarettes, lack of satisfaction was the primary reason for stopping e-cigarette use (32%) and those who reported this were less likely to start using e-cigarettes again at follow-up (Adjusted Odds Ratio (AOR)=0.58).

CONCLUSIONS

Specific reasons for using and stopping e-cigarettes predict changes in smoking and e-cigarette use, and targeting these beliefs could promote desired behaviour changes.

The potential impact of removing a ban on electronic nicotine delivery systems using the Mexico smoking and vaping model (SAVM)

Objective

To develop the Mexico Smoking and Vaping Model (Mexico SAVM) to estimate cigarette and electronic nicotine delivery systems (ENDS) prevalence and the public health impact of legalizing ENDS use.

Methods

SAVM, a cohort-based discrete-time simulation model, compares two scenarios. The ENDS-Restricted Scenario estimates smoking prevalence and associated mortality outcomes under the current policy of an ENDS ban, using Mexico-specific population projections, death rates, life expectancy, and smoking and e-cigarette prevalence. The ENDS-Unrestricted Scenario projects smoking and vaping prevalence under a hypothetical scenario where ENDS use is allowed. The impact of legalizing ENDS use is estimated as the difference in smoking- and vaping-attributable deaths (SVADs) and life-years lost (LYLs) between the ENDS-Restricted and Unrestricted scenarios.

Results

Compared to a national ENDS ban, The Mexico SAVM projects that legalizing ENDS use could decrease smoking prevalence by 40.1% in males and 30.9% in females by 2049 compared to continuing the national ENDS ban. This reduction in prevalence would save 2.9 (2.5 males and 0.4 females) million life-years and avert almost 106 (91.0 males and 15.5 females) thousand deaths between 2025 and 2049. Public health gains decline by 43% to 59,748 SVADs averted when the switching rate is reduced by half and by 24.3% (92,806 SVADs averted) with a 25% ENDS risk level from that of cigarettes but increased by 24.3% (121,375 SVADs averted) with the 5% ENDS risk.

Conclusions

Mexico SAVM suggests that greater access to ENDS and a more permissive ENDS regulation, simultaneous with strong cigarette policies, would reduce smoking prevalence and decrease smoking-related mortality. The unanticipated effects of an ENDS ban merit closer scrutiny, with further consideration of how specific ENDS restrictions may maximize public health benefits.

Chemicals in Cigarette Flavor Capsules From Guatemala and Mexico

BACKGROUND

The global market share for cigarettes with flavor capsules has grown exponentially over the last decade, particularly in Latin America. When smoking, consumers crush a liquid capsule in the filter that flavors the smoke. Little is known about the chemical constituents of the liquids in capsules or their potential health risks.

METHODS

Based on consumer data and availability in Mexico and Guatemala, 31 flavor capsule brands were purchased (19 and 12, respectively) in 2020. Since some cigarettes included multiple capsules in a stick (up to 2) or pack (up to 4), the final analytic sample included 50 capsules. We conducted qualitative and quantitative analyses using gas chromatography with mass spectrometry (GC-MS, Agilent Technologies, Inc).

RESULTS

The qualitative analysis detected 296 compounds (range = 9-67 per capsule), and all capsules contained menthol. Among the compounds detected in more than half the sample were limonene, menthone, benzaldehyde, eucalyptol, and triacetin. Traces of nicotine were found in 22% of the capsules. In the quantitative analysis, menthol concentrations were 33 times greater than the next most common compound (limonene). Benzyl alcohol and vanillin were also found in high concentrations. Comparing same-brand varieties across countries showed substantial variability in the concentration of menthol and other compounds.

CONCLUSIONS

Menthol is an omnipresent constituent in capsule cigarettes, perhaps because of its anesthetizing and reinforcing addictive properties. Other compounds found are toxic, potentially carcinogenic, and may enhance addictiveness. Variance in the presence and concentrations of such compounds highlights the importance of product standards to regulate capsule content.

IMPLICATIONS

This study evaluated the chemical content of capsule cigarettes from two Latin American countries that have two of the highest market shares for capsule cigarettes worldwide. Compared to other studies, our assessment included brand varieties from two countries to compare the differences in chemical content by country. Our results yield that menthol is found in all capsules, and that other chemicals found may prolong nicotine exposure and therefore reinforce the addictive properties of cigarettes.

Prevalence and perceptions of flavour capsule cigarettes among adults who smoke in Brazil, Japan, Republic of Korea, Malaysia and Mexico: findings from the ITC surveys

INTRODUCTION

The global market of flavour capsule cigarettes (FCCs) has grown significantly over the past decade; however, prevalence data exist for only a few countries. This study examined prevalence and perceptions of FCCs among adults who smoke across five countries.

METHODS

Cross-sectional data among adults who smoked cigarettes came from the International Tobacco Control Policy Evaluation Project Surveys-Brazil (2016/2017), Japan (2021), Republic of Korea (2021), Malaysia (2020) and Mexico (2021). FCCs use was measured based on reporting one's usual/current brand or favourite variety has flavour capsule(s). Perceptions of the harmfulness of one's usual brand versus other brands were compared between those who used capsules versus no capsules. Adjusted logistic regression models examined correlates of FCC use.

RESULTS

There were substantial differences in the prevalence of FCC use among adults who smoke across the five countries: Mexico (50.3% in 2021), Republic of Korea (31.8% in 2021), Malaysia (26.5% in 2020), Japan (21.6% in 2021) and Brazil (6.7% in 2016/2017). Correlates of FCC use varied across countries. Capsule use was positively associated with being female in Japan and Mexico, younger age in Japan, Republic of Korea and Malaysia, high education in Brazil, Japan and Mexico, non-daily smoking in Republic of Korea, and having plans to quit in Japan and Republic of Korea. There was no consistent pattern of consumer perceptions of brand harmfulness.

CONCLUSION

Our study documented the high prevalence of FCCs in some countries, pointing to the need to develop and implement regulatory strategies to control these attractive products.
