Background: Secondhand smoke exposure (SHS) is a major modifiable risk factor for morbidity and premature mortality. No study has assessed inequalities by sex in SHS exposure among adolescents globally. This study aims to explore the variations in SHS exposure among adolescents globally based on sex., Methods: Most recent data from 122 countries and territories that conducted the Global Youth Tobacco Survey between 1 January 2013 and 31 December 2020, comprising 557,332 respondents aged 11-17 years, were used to assess the prevalence of SHS exposure at home, in other enclosed public places, and at school. Multivariable Poisson regression models were performed to investigate the association between sex and SHS exposure in each country., Results: A total of 195,299 (35.0 %) adolescents reported exposure to SHS at home, 256,938 (46.1 %) in other enclosed public places, 258,528 (46.4 %) at school, and 399,644 (71.7 %) in any place. There were important inequalities in the prevalence of SHS exposure between countries. More girls than boys reported exposure to SHS at home in 54 countries (vs. one country with prevalence higher in boys than girls) and in other enclosed public places in 50 countries (vs. six countries). In contrast, the prevalence of SHS exposure at school was significantly higher in boys than girls in 25 countries while the opposite was observed in 14 countries., Conclusions: These findings emphasize the disparities in SHS exposure between adolescent boys and girls and, hence, highlight the urgent need to strengthen smoke-free policies and adopt targeted policies to address them., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 The Authors.

Introduction: The majority of users of tobacco and nicotine products start using them in adolescence. In order to keep equity considerations at the forefront of tobacco control, it is crucial to assess whether inequalities in prevalence of tobacco and nicotine use exist among adolescents globally., Methods: We conducted a secondary analysis of Global Youth Tobacco Survey (GYTS) data from 538644 school-based adolescents (79.3% aged 13-15 years) in 114 countries (2013-2019). Data were collected on current (past 30-day) use of cigarettes, smokeless tobacco, waterpipe tobacco and electronic cigarettes. We used weighted Poisson regression models adjusted for sex, pocket money, and age to assess differences in prevalence of current use between boys and girls, and between students with high versus low pocket money., Results: Although there was substantial regional variation, in most countries boys were statistically significantly more likely to report current use of all assessed products (ranging from 50.0% of countries for waterpipe tobacco to 73.3% of countries for electronic cigarettes). Inequalities by sex were less pronounced in Europe compared to other regions. Inequalities by pocket money were less consistent; students with more pocket money were more likely to report current use of cigarettes (vs those with less pocket money) in 61.8% of the countries, but more likely to report current use of smokeless tobacco in only 18.3% of countries., Conclusions: Globally, boys and adolescents with more pocket money are generally more likely to use a range of tobacco and nicotine products. However, these patterns are not universal and local variations should be taken into consideration to design effective and equitable tobacco control policies., Competing Interests: The authors have completed and submitted the ICMJE Form for disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Jawad M. et al.)

Introduction: Disposable e-cigarettes are the predominant type of vaping product used by adolescents and pose a significant public health concern. Identifying factors contributing to this growing trend is essential to curbing the vaping epidemic among youths. This study aims to investigate the growing prevalence and correlates of disposable e-cigarette use among US students., Methods: Data from 48437 US middle and high school students from the 2021 and 2022 National Youth Tobacco Survey (NYTS) were analyzed using logistic and ordinal regression models to evaluate disposable e-cigarette use and frequency of use (low, medium, and high) with demographic and psychosocial factors. Weighted prevalence of current e-cigarette use with 95% CIs by device types in 2021 and 2022, were calculated. Odds ratios (ORs) of correlations of disposable e-cigarette use and frequency of use with demographic and psychosocial factors were analyzed., Results: Disposable e-cigarette use increased from 3.9% (95% CI: 3.3-4.7) in 2021 to 5.1% (95% CI: 4.2-6.1) in 2022, and was associated with being female (OR=1.57; 95% CI: 1.29-1.91 vs male), high schoolers (OR=5.14; 95% CI: 3.96-6.67 vs middle schoolers), having low harm perceptions of e-cigarettes (OR=7.75; 95% CI: 5.58-10.75 vs lot of harm), and high exposure to marketing (OR=1.57; 95% CI: 1.05-2.35 vs low exposure). Identifying as LGBTQ (OR=1.41; 95% CI: 1.00-2.00 vs straight), having low academic performance (OR=2.16; 95% CI: 1.15-4.07, D vs A grades), and having psychological distress (OR=2.01; 95% CI: 1.64-2.47, severe vs none) were also linked to increased frequency of use., Conclusions: This study underscores increasing disposable e-cigarette use among US students, noting existing disparities. It identifies high-risk adolescent subgroups vulnerable to disposable e-cigarette use. These findings emphasize the urgency of targeted prevention and stricter regulations on disposable e-cigarettes to combat nicotine addiction among youths., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Chen D.T.H. et al.)

Introduction: E-cigarette use remains a controversial topic, with questions over how people transition between e-cigarette use and cigarette smoking. This paper examined transitions into and out of nicotine product use in a representative sample of UK youth., Methods: We used Markov multistate transition probability models on data from 10 229 participants (10-25 years old) in the UK Household Longitudinal Study (2015-2021). We used four product use states ('never', 'non-current use', 'e-cigarette only' and 'smoking and dual use') and estimated likelihood of transitions according to sociodemographic characteristics., Results: Among participants who had never used nicotine products, most were still non-users a year later (92.9% probability; 95% CI 92.6%, 93.2%); a small proportion transitioned to using e-cigarettes only (4.0%; 95% CI 3.7%, 4.2%) and cigarettes (2.2%; 95% CI 2.0%, 2.4%). Those aged 14-17 years were the most likely to start using a nicotine product. E-cigarette use was less persistent overtime than cigarette smoking, with a 59.1% probability (95% CI 56.9%, 61.0%) of e-cigarette users still using after 1 year compared with 73.8% (95% CI 72.1%, 75.4%) for cigarette smoking. However, there was a 14% probability (95% CI 12.8%, 16.2%) that e-cigarette users went onto smoke cigarettes after 1 year, rising to 25% (95% CI 23%, 27%) after 3 years., Conclusion: This study found that although overall nicotine product use was relatively rare, participants were more likely to experiment with e-cigarette use than cigarette smoking. This was mostly not persistent over time; however, approximately one in seven transitioned to cigarette smoking. Regulators should aim to deter all nicotine product use among children., Competing Interests: Competing interests: AAL is a trustee of Action on Smoking and Health.

Introduction: This study examined menthol cigarette use among youth who smoked, after menthol cigarette bans were implemented in England (May 2020) and Canada (October 2017)., Aims and Methods: Cross-sectional data come from 2021 ITC Youth Tobacco and Vaping Survey respondents aged 16-19 who smoked in the past 30 d in England (N = 715) and Canada (N = 419). Adjusted logistic regression models, estimated separately for each country, examined sociodemographic correlates of usually smoking menthol cigarettes (reporting currently most often smoking menthol cigarettes) overall, and by past 30-d use of any menthol accessories (e.g., filters, capsules). Youth reported the cigarette variety they smoked most often, coded as menthol or nonmenthol., Results: Almost no youth who smoked in the past 30 d reported most often smoking a cigarette variety coded as menthol. However, 34.5% (95% CI: 30.4% to 38.9%) of youth who smoke in England and 30.9% (26.0%-36.3%) in Canada reported usually smoking menthol cigarettes, with greater odds of use among those identifying as black, or other race/ethnicity, respectively, compared to white in England (60.0%, aOR = 3.08, p = .001; 47.4%, aOR = 2.27, p = .011) and Canada (43.6%, aOR = 2.44, p = .046; 51.2%, aOR = 2.92, p = .001). Among those who reported usually smoking menthol cigarettes in England (N = 223) and Canada (N = 108), 71.7% (64.0%-78.2%) and 51.5% (41.1%-61.7%) reported using menthol accessories., Conclusions: After menthol cigarette bans in England and Canada, approximately one-third of youth who smoked reported usually smoking menthol cigarettes, with disproportionately higher use among those identifying as black and other race/ethnicity. Menthol accessories accounted for most menthol cigarette use. Closing regulatory loopholes is critical to advancing public health equity., Implications: Use of menthol cigarette accessories (eg, filters, cards, capsules) among youth who smoked was prevalent after implementation of menthol cigarette bans in England and Canada, and there was disproportionately higher use among those who identified as black and any other race/ethnicity. Efforts are therefore required to close regulatory loopholes of menthol cigarette bans. Findings further support countries, such as the United States, proposing menthol cigarette bans which extend coverage to accessories. More comprehensive menthol bans that also restrict accessories are likely to be more effective in reducing flavored tobacco use among young people and in advancing health equity., (© The Author(s) 2024.

Background: Adolescent nicotine and tobacco product use remains common despite declining smoking rates in the United States, likely due to the emergence of novel products. Concurrent use of multiple products may increase the risk of nicotine dependency and subsequent substance use., Aim: To identify patterns and trends of dual and poly nicotine and tobacco use among adolescents in the US and explore associations of dual and poly nicotine and tobacco use with sociodemographic factors., Methods: 12 years of annual National Youth Tobacco Survey data (2011-2022) from 242,637 respondents were used to examine prevalence trends of different combinations of nicotine or tobacco product use among adolescents in the US using weighted point estimates for each year. Poisson regression models examined sociodemographic factors associated with different patterns of dual and poly-product use from 2011 to 2022., Results: Overall, the prevalence of dual (i.e. at least two products) and poly (i.e. at least three products) use decreased between 2011 and 2021 (from 9.5 % to 2.8 % and from 5.1 % to 1.1 %, respectively), but showed signs of increase between 2021 and 2022 (3.7 % for dual and 1.7 % for poly use). The most common combinations included a combustible product with either a novel or noncombustible product. The risk for dual and poly-product use was higher among non-Hispanic Whites, males, and high school students., Conclusions: Previously declining trends in the prevalence of tobacco/nicotine dual and poly use may have been reversed. Close monitoring and targeted tobacco control policies are essential to tackle multiple product use among adolescents., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

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., Competing Interests: Competing interests: JFT has served as paid expert witness in legal challenges against tobacco and vaping companies.

Introduction: To reduce the appeal of tobacco, the European Union (EU) banned menthol as a characterising flavour in cigarettes in May 2020. This pre/post-study evaluated the impact of the menthol ban on smoking cessation outcomes among a representative cohort of Dutch smokers., Methods: Adult (18+ years) smokers were recruited at wave 1 (pre-ban) of the International Tobacco Control Netherlands Surveys (February-March 2020) and followed post-ban at wave 2 (September-November 2020) and wave 3 (June-July 2021) (N=1326 participated in all three waves). Weighted bivariate, logistic regression and generalised estimating equation model analyses were conducted., Results: Usual menthol use decreased from pre-ban (7.8%) to post-ban (4.0% at wave 2 and 4.4% at wave 3) (p<0.001). Pre-ban menthol smokers had greater odds of making a post-ban quit attempt than non-menthol smokers (66.9% vs 49.6%, adjusted OR (aOR)=1.89, 95% CI: 1.13 to 3.16). Compared with pre-ban non-menthol smokers, a higher proportion of menthol smokers quit by wave 2 (17.8% vs 10.2%, p=0.025) and by wave 3 (26.1% vs 14.1%, p=0.002), although this was not significant after adjusting for other factors. Female pre-ban menthol smokers had greater odds of quitting by wave 3 than female non-menthol smokers (aOR=2.23, 95% CI: 1.10 to 4.51). Most pre-ban menthol smokers (n=99) switched to non-menthol cigarettes (40.0%) or reported that they continued to smoke menthol cigarettes (33.0%) at wave 3., Conclusions: The EU menthol ban was effective in reducing menthol use and in increasing quit attempts and quitting among pre-ban menthol smokers. Impact could be maximised by closing gaps that allow post-ban menthol cigarette use., Competing Interests: Competing interests: GF has been an expert witness or consultant for governments defending their country’s policies or regulations in litigation and served as a paid expert consultant to the Ministry of Health of Singapore in reviewing the evidence on plain/standardised packaging.

Objective: The majority of tobacco users have had their first contact with nicotine at a young age. The aim of this study was to explore the association between the first tobacco or nicotine product tried and the transition to regular product use in 28 European countries., Methods: A secondary analysis of participants aged 15-40 years (n=8884) from 28 countries was conducted (Eurobarometer wave 93.2; August-September 2020). Participants who reported having ever tried tobacco or nicotine products were asked which product they tried first. Self-reported history of tobacco use determined whether they were established users (≥1 time weekly) of a range of products at any point in their life. Multilevel logistic regression was used to measure the association between first product tried and becoming a regular user of tobacco or nicotine products., Results: There was large variation between countries in the proportion of participants aged ≤40 years that ever tried tobacco or nicotine; Estonia had the highest proportion of ever users (85.8%) and Poland had the lowest (38.9%). Among those who had ever tried tobacco or nicotine, boxed cigarettes were the most common first product (72.3%) and pipe was the least common (0.4%). Compared with those who first tried e-cigarettes, the odds of ever becoming a regular user of any tobacco or nicotine product were higher among those who first had hand-rolled cigarettes (adjusted OR, aOR 2.23; 95% CI 1.43 to 3.48) or boxed cigarettes (aOR 2.08; 95% CI1.43 to 3.02) and lower among those who first tried waterpipe (aOR 0.22; 95% CI 0.14 to 0.34)., Conclusions: Although this study cannot infer causality, the findings show that odds of becoming a regular tobacco user differs widely depending on the first product used. Better understanding of the associations between first product use and regular tobacco use could be informative to tobacco control policy-makers and help tailor prevention programmes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: Analysis of the tobacco market can provide valuable insights for developing tobacco control strategies. This study examines the market trends of cigarettes, cigars/cigarillos, smoking tobacco, smokeless tobacco, e-cigarettes, heated tobacco products (HTPs), and tobacco-free oral nicotine, across 97 countries between 2007 and 2021., Methods: We obtained annual tobacco retail value data from Euromonitor Passport and calculated the market share for each type of tobacco product. The research examined trends in retail value and market share globally, stratified by national income level, as well as in individual countries., Results: From 2007 to 2015, the growth of the global tobacco market was primarily driven by cigarette sales. However, starting in 2016, emerging products, including e-cigarettes, HTPs, and tobacco-free oral nicotine, as well as non-cigarette combustible products, including cigars/cigarillos and smoking tobacco, have been mostly responsible for the increases in the global tobacco retail value. High-income countries experienced the greatest increase in the retail value of emerging products, while middle- and low-income countries still observed rises in cigarette sales., Conclusions: Trends in the retail value of different tobacco products varied widely during the study period, with distinct trends observed in different income levels and within individual countries. These trends can supplement prevalence data and be used to inform local tobacco control policies., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Liu Y. and Filippidis F.T.)

Background: Social media use is high among children and young people and might influence health behaviours. We examined social media use and use of tobacco and e-cigarettes in the UK., Methods: We used data from participants aged 10-25 years from the UK Household Longitudinal Study (January 2015-January 2022). Participants were asked: "On a normal weekday, that is Monday to Friday, how many hours do you spend chatting or interacting with friends through a social website or app like that?". Specific social media platforms were not specified. Responses were none, less than 1 h, 1-3 h, 4-6 h, 7 h or more. Outcomes were current tobacco smoking and e-cigarette use. Generalised Estimating Equation (GEE) logistic regression models investigated associations of social media use with tobacco and e-cigarette use, and fixed effects analyses investigated changes in social media use with uptake of both products. Models included possible confounders such as age, sex, household income, ethnicity (White vs non-White) and use of tobacco or e-cigarettes by others within the home. All participants gave written informed consent., Findings: The analytic sample included 10 808 participants with 27 962 observations (mean age 15·7 years [SD 3·8], 5080 [47%] male, 5728 [53%] female, and 7868 [73%] White). Current tobacco smoking was reported at one or more timepoints by 929 (8·6%) participants, and current e-cigarette use by 270 (2·5%) participants. In adjusted GEE models, all levels of social media use were associated with greater odds of current smoking than no use. This association was particularly apparent at higher levels of use adjusted odds ratio [aOR] 3·11, 95% CI 2·41-4·03 for ≥7 h use vs no use), with similar associations for e-cigarettes (aOR 3·04, 2·11-4·40 for ≥7 h use vs no use). Fixed effects analyses also found increased use of social media to be associated with increased uptake of both products (eg, changing to using social media for ≥7 h/day was associated with >2 times the odds of taking up tobacco smoking [aOR 2·33, 1·28-4·24])., Interpretation: These analyses suggest an association between social media use and e-cigarette and tobacco use. Potential pathways include promotion of these products on social media. Further research with details on specific platforms would be useful as well as with longer follow-up time., Funding: Cancer Research UK., (Copyright © 2023 Elsevier Ltd. All rights reserved.)

Background: Patterning of cigarette and e-cigarette use among young people remains poorly characterized. We aimed to describe these patterns in the UK Millennium Cohort Study at age 14 and 17 years., Methods: Data on cigarette and e-cigarette use come from 9731 adolescents. Latent class analysis assigned participants to membership of classes of product use and multinomial logistic regression analyses assessed differences in the likelihood of belonging to classes by sociodemographic (age, gender, ethnicity, household income, maternal education and country of residence) and smoking-related social factors (caregiver tobacco use, caregiver e-cigarette use and peer smoking)., Results: We identified four classes of use: 45.8% of adolescents 'continued to abstain' from cigarettes or e-cigarettes; 21.3% 'experimented' (used once or in the past but not currently) with cigarettes and/or e-cigarettes by age 17 but were not current users; 19.0% were 'late adopters', characterized by low levels of use at age 14 but high levels of experimentation and current use at age 17; and 13.9% were 'early adopters', characterized by high levels of experimentation and current use at ages 14 and 17. At age 17, 70.4% of 'early adopters' smoked cigarettes regularly plus an additional 27.3% experimented with cigarettes. Corresponding percentages for e-cigarettes were 37.9% and 58.9%. Tobacco and e-cigarette use by caregivers, and cigarette use by peers, were associated with being both 'late adopters' and 'early adopters'., Conclusions: Approximately one in seven adolescents in the UK are 'early adopters' of nicotine products. This highlights the need to develop and implement effective policies to prevent nicotine use uptake., (© The Author(s) 2023.

Background: Global adoption of standardised packaging requirements for tobacco products is a victory for public health, but their proliferation and impacts rely partly on public support. How this is related to legislation remains underassessed. This study explored change over time in public support for standardised packaging in countries with varying degrees of legislative provisions., Methods: We used data from 27 European countries, collected from 2017 (n=28, 300) and 2020 (n=27, 901) waves of the Eurobarometer survey, to assess self-reported support for standardised packaging regulations among both smokers and non-smokers. Countries were grouped into three categories of policy adoption (policy implemented; policy legislated; no legislation) and changes in support were assessed using multilevel Poisson regression models., Results: In 2020, public support for standardised packaging was 71% (95% CI 68% to 74%) in countries that implemented standardised packaging legislation, 57% (55% to 60%) in countries that had legislated but not yet implemented legislation and 41% (40%to 42%) in countries with no legislation. Compared with 2017, this represented a relative change of +8% (1% to 15%), +12% (5% to 21%) and -5% (95% CI -2% to -8%), respectively, in the three country categories. Among smokers, there was no indication of change in support across the three groups. Among non-smokers, support increased in countries with existing legislation (adjusted prevalence ratio [aPR]=1.14, 95% CI 1.06 to 1.23) and decreased in countries with no legislation (aPR=0.93, 0.90 to 0.97)., Conclusions: Public support for standardised packaging regulations increased in countries implementing and legislating for these measures, particularly among non-smokers. An overall increase in support provides reassurance for policymakers defending policy action on tobacco packaging, as well as for those seeking to implement standardised packaging in their own countries. ., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

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). Bivariate, logistic regression and generalized estimating equation model analyses were conducted on weighted data., Results: Illicit purchasing remained low from pre-ban (2.4%, 95% CI: 1.8-3.2, Wave 1) to post-ban (1.7%, 1.2-2.5%, Wave 3), with no difference between menthol and non-menthol smokers from Wave 1 to Wave 3. About 4.4% of post-ban menthol smokers last purchased their usual brand outside of the EU and 3.6% from the internet; 42.5% of post-ban menthol smokers and 4.4% of smokers overall reported using flavour accessories, with greater odds among those aged 25-39 years vs. 55+ (aOR = 3.16, P = 0.002). Approximately 70% of post-ban smokers who reported using a menthol brand were actually using a non-menthol replacement brand., Conclusions: There was no increase in illicit purchasing or of smuggling outside the EU among menthol and non-menthol smokers in the Netherlands 1 year after the EU menthol cigarette ban. Use of flavour accessories and non-menthol replacement brands best explain post-ban menthol use, suggesting the need to ban accessories and ensure industry compliance., (© The Author(s) 2023.

Introduction: It is illegal in the UK to sell tobacco or nicotine e-cigarettes to people under the age of 18 years, as is displaying tobacco cigarettes at the point of sale. This paper examined changes in exposure to display of these products in shops and sources of these products among children and adolescent users over time METHODS: Data from representative repeated online cross-sectional surveys of youth in Great Britain (11-18 years) were used (2018-2022; n=12 445). Outcome measures included noticing product displays and sources of e-cigarettes and tobacco cigarettes. Logistic regressions examined the associations of these outcome variables over time and with sociodemographic variables., Results: Of 12 040 participants with complete data, 10.1% used some form of nicotine product (4.2% cigarettes, 2.9% e-cigarettes, 3.0% both) at least occasionally. The likelihood of noticing tobacco cigarettes on display fell over time for both supermarkets (2018: 67.1% to 2022: 58.5%) and small shops (2018: 81.3% to 2022: 66.3%), but the likelihood of noticing e-cigarettes in supermarkets rose (2018: 57.4% to 2022: 66.5%). Sources of tobacco cigarettes did not differ over time, but e-cigarette users were more likely to get their e-cigarettes from small shops in 2022 (51.2%) vs 2019 (34.2%) (OR 2.02, 95% CI 1.24, 3.29)., Conclusion: This study provides evidence that current policies to limit awareness of and access to both tobacco and e-cigarettes among adolescents in the UK may not be effective. UK policies on the advertising, promotion and sale of both tobacco and e-cigarettes need to be reinforced to deter use among children and adolescents., Competing Interests: Competing interests: NSH is chair of Action on Smoking and Health and medical director of Asthma and Lung UK.

Background: Limited data on electronic cigarette prevalence, patterns, and settings of use are available from several European countries., Methods: Within the TackSHS project, a face-to-face survey was conducted in 2017-2018 in 12 European countries (Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania and Spain). Overall, 11,876 participants, representative of the population aged ⩾15 years in each country, provided information on electronic cigarette., Results: 2.4% (95% confidence interval [CI], 2.2-2.7%) of the subjects (2.5% among men and 2.4% among women; 0.4% among never, 4.4% among current- and 6.5% among ex-smokers) reported current use of electronic cigarette, ranging from 0.6% in Spain to 7.2% in England. Of the 272 electronic cigarette users, 52.6% were dual users (ie, users of both electronic and conventional cigarettes) and 58.8% used liquids with nicotine. In all, 65.1% reported using electronic cigarette in at least one indoor setting where smoking is forbidden; in particular, at workplaces (34.9%) and bars and restaurants (41.5%). Multivariable logistic regression analysis showed that electronic cigarette use was lower among older individuals (P for trend <0.001) and higher among individuals with high level of education (P for trend = 0.040). Participants from countries with higher tobacco cigarette prices more frequently reported electronic cigarette use (odds ratio 3.62; 95% CI, 1.80-7.30)., Conclusion: Considering the whole adult population of these 12 European countries, more than 8.3 million people use electronic cigarettes. The majority of users also smoked conventional cigarettes, used electronic cigarettes with nicotine, and consumed electronic cigarettes in smoke-free indoor areas.

The global consumption of flavoured cigarettes, particularly capsule and menthol non-capsule cigarettes, has been rising rapidly. Their attractiveness has been fuelled by perceptions of improved palatability, along with industry marketing tactics such as lower price points in some regions. This study aimed to compare prices of unflavoured, capsule, and menthol non-capsule cigarettes across 65 countries by analysing 2018 cigarette price data from Euromonitor Passport. Median prices of capsule and menthol non-capsule cigarettes were each compared to unflavoured cigarettes at the country-level. Countries were included in the analysis if they contained price data for capsule or menthol non-capsule and unflavoured cigarettes (n = 65). The median price of capsule cigarettes was the same as unflavoured cigarettes in 12 out of 50 countries and not statistically different in another 31 countries (p > 0.05). Capsule cigarettes were more expensive than unflavoured cigarettes in five countries and cheaper in two (p < 0.05). The median price of menthol non-capsule cigarettes was the same as unflavoured cigarettes in 6 out of 51 countries and not statistically different in another 39 countries (p > 0.05). Menthol non-capsule cigarettes were more expensive than unflavoured cigarettes in five countries and cheaper in one country (p < 0.05). There was no pattern found in the pricing of capsule or menthol non-capsule cigarettes, suggesting variability in the tobacco industry's pricing strategies across countries. Tailoring tobacco control policies to match national market conditions, particularly in countries with significant market shares of capsule and menthol non-capsule cigarettes could help address the public health threat posed by the tobacco epidemic., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Introduction: Raising tobacco prices via increased taxation may be undermined by tobacco industry tactics to keep budget cigarettes on the market. Price differentials between budget and premium cigarettes allow smokers to trade down in the face of average price rises thus attenuating health benefits. This study examines global trends of price differentials and associations with taxation., Methods: Ecological analysis of country-level panel data of 195 countries' price differentials was performed and compared against total, specific excise, ad valorem and other taxation. Price differentials were expressed as the difference between budget cigarette and premium pack prices (as % of premium pack prices). Two-level linear regression models with repeated measurements (2014, 2016 and 2018) nested within each country assessed the association between country-level taxation structures and price differentials, adjusted for year, geographical region and income group., Results: Worldwide, median price differential between budget and premium 20-cigarette packs was 49.4% (IQR 25.9%-70.0%) in 2014 and 44.4% (IQR 22.5%-69.4%) in 2018 with significant regional variation. The largest price differentials in 2018 were in Africa, with the lowest in Europe. Total taxation was negatively associated with price differentials (-1.5%, 95% CI -2.5% to -0.4% per +10% total taxation) as was specific excise taxation (-2.5%, 95% CI -3.7% to -1.2% per +10% specific excise tax). We found no statistically significant association between ad valorem taxation and price differentials., Conclusion: Total levels of taxation and specific excise taxes were associated with smaller price differentials. Implementing high specific excise taxes may reduce price differentials and improve health outcomes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: In Southeast Asia, tobacco use is a major public health threat. Tobacco users in this region may switch between or concurrently use smoked tobacco and smokeless tobacco (SLT), which makes effective tobacco control challenging. This study tracks transitions of use among different product users (cigarettes, bidis, and SLT) in Bangladesh, one of the largest consumers of tobacco in the region, and examines factors related to transitions and cessation., Methods: Four waves (2009-2015) of the International Tobacco Control (ITC) Bangladesh Survey with a cohort sample of 3245 tobacco users were analysed. Generalized Estimating Equations (GEE) models were used to explore the socioeconomic correlates of transitions from the exclusive use of cigarettes, bidis, or SLT to the use of other tobacco products or quitting over time., Findings: Among exclusive cigarette users, most remained as exclusive cigarette users (68.1%). However, rural smokers were more likely than urban smokers to transition to bidi use (odds ratio [OR] = 3.02, 95% confidence interval [CI] = 1.45-6.29); to SLT use (OR = 2.68, 95% CI = 1.79-4.02) and to quit tobacco (OR = 1.57, 95% CI = 1.06-2.33). Among exclusive bidi users, transitional patterns were more volatile. Fewer than half (43.3%) of the exclusive bidi users maintained their status throughout the waves. Those with higher socio-economic status (SES) were more likely to quit (OR = 4.16, 95% CI = 1.08-13.12) compared to low SES smokers. Exclusive SLT users either continued using SLT or quit with minimal transitions to other products (≤2%). Nevertheless, males were more likely to switch to other tobacco products; younger (OR = 2.94, 95% CI = 1.23-6.90 vs. older), more educated (OR = 1.55, 95% CI = 1.77-3.12 vs. less educated), and urban SLT users (OR = 0.52, 95% CI = 0.30-0.86 for rural vs. urban users) were more likely to quit., Interpretation: Complex transitional patterns were found among different types of tobacco product users over time in Bangladesh. These findings can inform more comprehensive and multi-faceted approaches to tackle diversified tobacco use in Bangladesh and neighbouring countries in the Southeast Asia region with similar tobacco user profiles of smoked tobacco and SLT products., Funding: This is an unfunded observational study with the use the ITC Bangladesh datasets. The ITC Bangladesh Surveys were supported by grants from the US National Cancer Institute (P01 CA138389), the International Development Research Centre (IDRC Grant 104831-003), and Canadian Institutes of Health Research (MOP-79551, MOP-115016)., Competing Interests: GTF has served as an expert witness or a consultant for governments defending their country's policies or regulations in litigation.

Objective: This systematic review on flavour capsule cigarettes aims to examine prevalence, correlates of use, behaviours and perceptions of these products globally., Data Sources: A search of original, peer-reviewed research without restrictions in publication year, population, study design or language, using a combination of cigarette and capsule terms was conducted across four databases (Medline, Embase, Web of Science and Scopus), indexed until 30 April 2021., Study Selection: Studies were included if they presented original, human subjects research on flavour capsule cigarettes., Data Extraction: Two authors independently extracted data on main outcome results and assessed risk of bias using a validated quality assessment tool (QATSDD)., Data Synthesis: Of 842 unduplicated database records and four studies from citation searching screened, 20 studies were included in the review. Studies reported data from 2009 to 2019 across eight countries, the majority of which used cross-sectional or focus group study designs. Current capsule use among smokers was highest in Chile and Mexico (40%) and was associated with younger age, and in some countries, with being female. Capsule cigarettes are perceived as tasting better, being smoother on the throat, more fun to smoke, and more attractive compared with non-capsule cigarettes, particularly among susceptible non-smokers and non-daily smokers., Conclusion: Findings call for the adoption of comprehensive tobacco control policies that account for flavour capsules and similar iterations, which can increase appeal through flavours and innovative features. Continued monitoring and research of these products is critical, with particular attention to low-income and middle-income countries, which make up a disproportionately larger share of the capsule market., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: This systematic review aims to identify marketing elements of flavour capsule variants (FCVs), cigarettes that release flavour when a capsule(s) embedded in the filter is crushed., Data Sources: A search of original research without restrictions in publication year, population, study design or language using a combination of cigarette and capsule terms was conducted across four databases (Medline, Embase, Web of Science and Scopus), indexed until 13 December 2021, along with a citation search., Study Selection: Studies were included if they presented original research relevant to marketing features of FCVs., Data Extraction: One author performed data extraction and coded outcomes based on '4Ps' of marketing mix theory: product, place, price and promotion. The second author conducted a cross-check., Data Synthesis: Of 2436 unduplicated database records and 30 records from other sources, 40 studies were included in the review. Studies were published between 2009 and 2021. Study methodologies primarily included content analysis of cigarette packs/sticks, review of tobacco industry documents and content analysis of advertising information. Findings suggest FCVs are marketed using a mix of strategies, particularly characterised by product innovation, timing market launches around tobacco policies, point-of-sale advertising and packaging to communicate a high-tech, customisable and flavourful product., Conclusion: Findings illuminate the marketing strategies of FCVs that are likely driving their global growth, particularly among young people and in low and middle-income countries. Comprehensive tobacco control regulations are needed to close loopholes and curb industry efforts to circumvent existing policies in order to mitigate uptake of FCVs and other product innovations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: Transitions between different tobacco products are frequent among tobacco users in Bangladesh; however, the reasons leading to such transitions and why they quit are not well researched. The aim of the study is to examine perceptions and reasons reported by tobacco users in Bangladesh to transition to other products or quit., Methods: Data from four waves (2009-2015) of the International Tobacco Control (ITC) Bangladesh Survey were used. Repeated data on perceptions and reasons for exclusive cigarette (n=520), bidi (n=130), and SLT users (n=308) to either start using other products or quit were analyzed with sampling weights. The percentages of responses across waves were used to calculate the pooled proportion data using a meta-analysis approach., Results: Common reasonsig for respondents switching to other tobacco products were influence of friends/family (73.8-86.0%), and curiosity (44.4-71.3%). The perceived calming effect of smoking cigarettes and bidis (43.2-56.9%), and the impression that bidis were less harmful (52.3%) and taste better (71.2%) were major reasons for exclusive SLT users to switch products. Health concerns (16.5-62.7%) and disapproval from friends/family (29.8-56.4%) were generally the main reasons for quitting. For smoked tobacco users, doctor's advice (41.6%), package warning labels (32.3%), and price (32.4%) seemed to be the major driving factors to quit., Conclusions: Results highlight that the reasons for switching between tobacco products and quitting include social factors (e.g. friends/family) and (mis) perceptions regarding the products. Tobacco control policy could emphasize cessation support, increased price and education campaigns as key policies to reduce overall tobacco use in Bangladesh. Data from four waves (2009-2015) of the International Tobacco Control (ITC) Bangladesh Survey were used. Repeated data on perceptions and reasons for exclusive cigarette (n=520), bidi (n=130), and SLT users (n=308) to either start using other products or quit were analyzed with sampling weights. The percentages of responses across waves were used to calculate the pooled proportion data using a meta-analysis approach., Competing Interests: The authors have each completed and submitted an ICMJE form for disclosure of potential conflicts of interest.
