Background: China has one of the highest levels of tobacco consumption globally, and there is no national smoke-free legislation. Although more than 20 Chinese cities have passed local smoke-free laws since 2008, evidence on their effectiveness in reducing smoking behaviours and their economic benefits is scarce. By exploiting a natural quasi-experiment, whereby a comprehensive public smoking ban was implemented in Shanghai in March, 2017, this study aims to assess the impact of the policy on individual smoking behaviours and quantify its effect on macroeconomic outcomes., Methods: In this difference-in-differences analysis and modelling study, we used data on smoking behaviours from the 2012, 2014, 2016, and 2018 waves of the China Family Panel Studies. We used a difference-in-differences approach to investigate trends in smoking prevalence in respondents in Shanghai, relative to respondents from other direct-administered municipalities, provincial capital cities, and subprovincial municipalities (control group), after the implementation of a smoking ban in 2017. All respondents aged 18 years or older were included, with the exception of people who lived in Beijing and rural areas. The primary variable of interest in the difference-in-differences analysis was self-reported smoking status. Based on the difference-in-differences estimation of reduction in smoking prevalence, we then used a health-augmented macroeconomic model to estimate the potential macroeconomic gains if such a ban was implemented across China for the period 2017-35., Findings: 14 688 respondents were included in the analysis: 5766 from Shanghai and 8922 from the control group. After the implementation of the smoking ban in Shanghai in 2017, smoking prevalence decreased by 2·2 percentage points (95% CI 2·1-2·3), equivalent to an 8·4% reduction in the number of current smokers. The smoking ban had a larger effect on men, people with a higher level of education, unmarried people, and younger people when compared with their respective counterparts. The modelling analysis showed that implementing a nationwide comprehensive public smoking ban similar to that in Shanghai would result in a 0·04-0·07% increase in the national gross domestic product in China between 2017 and 2035, outweighing the economic costs of smoking ban enforcement., Interpretation: The smoking ban in Shanghai shows that a comprehensive public smoking ban with strict enforcement is effective in curbing smoking behaviours. Moreover, the implementation of a comprehensive public smoking ban across China would be cost-effective., Funding: National Social Science Fund of China., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

We use data from the Population Assessment of Tobacco Use and Health (PATH), a longitudinal data set including self-reported and biomarker measures of tobacco use, to examine the effects of state-level tobacco 21 (T21) laws on smoking and vaping. T21 laws reduce self-reported cigarette smoking among 18-to-20 year olds, concentrated in males. Initial non-users who "age-out" of treatment are less likely to subsequently initiate self-reported smoking or vaping. Treated smokers are less likely to buy their own cigarettes and more likely to buy cigarettes in a different state. Biomarker results are mixed, and we find some evidence of a reduction in nicotine exposure but less evidence for a reduction in exposure to tobacco. Finally, we test for non-classical measurement error. T21 laws reduce the probability that clinically identified likely cigarette smokers self-report as smokers, which may increase the apparent effect of T21 laws on cigarette smoking as measured by self-reports., 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., (Copyright © 2024 Elsevier B.V.

Introduction: Estimating the prevalence of second-hand tobacco smoke exposure is a public health priority while evaluating the population-attributable disease burden and impact of smoking bans. We conducted a systematic review to analyze how secondhand tobacco smoke exposure has been assessed, and how its prevalence has been estimated among the Portuguese population since the implementation of the partial smoking ban in 2008., Methods: A literature search was conducted in the Web of Science, MEDLINE and Embase databases until November 2022, applying a pre-designed search strategy and following the PRISMA 2020 guidelines. The search was not restricted by study period, study design, sample size or language, and was complemented by a manual literature search. A modified Newcastle-Ottawa scale was used to assess the quality of the studies., Results: Thirteen cross-sectional studies were included. The prevalence of second-hand tobacco smoke exposure among the three European studies ranged from 8.2% (adult population exposed at home in 2010) to 93.3% (adolescent/adult population exposed in bar/restaurant terraces in 2016). Three nationwide studies estimated children's exposure at home: ranging from 32.6% in 2010 - 2011 to 14.4% in 2016. According to the most recent studies, 49.8% of women living in Porto were exposed during the third trimester of pregnancy in 2010 - 2011; 32.6% and 38.4% of children were exposed at home, respectively in Lisbon and the Azores., Conclusion: A significant proportion of the Portuguese population, especially children and pregnant women, remain exposed to secondhand tobacco smoke. A comprehensive smoke-free policy is needed, not only in outdoor public places, but also in indoor private settings.

Background: An increasing number of countries are pursuing a tobacco 'endgame'. We sought to determine the combination of measures it would take to achieve a tobacco endgame in the city-state of Singapore., Methods: Using an open-cohort microsimulation model, we estimated the impact of existing measures (quit programmes, tobacco taxes, flavours ban) and more novel measures (very low nicotine cap, tobacco-free generation, raising the minimum legal age to 25 years), and combinations thereof, on smoking prevalence in Singapore over a 50-year horizon. We used Markov Chain Monte Carlo to estimate transition probabilities between the states of never smoker, current smoker and former smoker, updating each individual's state across each year with prior distributions derived from national survey data., Results: Without new measures, smoking prevalence is expected to rebound from 12.2% (2020) to 14.8% (2070). The only scenarios to achieve a tobacco endgame target within a decade are those combining a very low nicotine cap with a flavours ban. A nicotine cap or tobacco-free generation alone also achieve endgame targets, but after 20 and 39 years, respectively. Taxes, quit programmes, a flavours ban and minimum legal age increase do augment the impact of other measures, but even when combined are insufficient to achieve a tobacco endgame target within 50 years., Conclusion: In Singapore, achieving a tobacco endgame within a decade requires a very low nicotine cap coupled with a tobacco flavours ban, although this target can also be achieved in the long term (within 50 years) with a tobacco-free generation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Starting in the 1970s, individuals, businesses and the public have increasingly benefited from policies prohibiting smoking indoors, saving thousands of lives and billions of dollars in healthcare expenditures. Smokefree policies to protect against secondhand smoke exposure, however, do not fully protect the public from the persistent and toxic chemical residues from tobacco smoke (also known as thirdhand smoke) that linger in indoor environments for years after smoking stops. Nor do these policies address the economic costs that individuals, businesses and the public bear in their attempts to remediate this toxic residue. We discuss policy-relevant differences between secondhand smoke and thirdhand smoke exposure: persistent pollutant reservoirs, pollutant transport, routes of exposure, the time gap between initial cause and effect, and remediation and disposal. We examine four policy considerations to better protect the public from involuntary exposure to tobacco smoke pollutants from all sources. We call for (a) redefining smokefree as free of tobacco smoke pollutants from secondhand and thirdhand smoke; (b) eliminating exemptions to comprehensive smoking bans; (c) identifying indoor environments with significant thirdhand smoke reservoirs; and (d) remediating thirdhand smoke. We use the case of California as an example of how secondhand smoke-protective laws may be strengthened to encompass thirdhand smoke protections. The health risks and economic costs of thirdhand smoke require that smokefree policies, environmental protections, real estate and rental disclosure policies, tenant protections, and consumer protection laws be strengthened to ensure that the public is fully protected from and informed about the risks of thirdhand smoke exposure., Competing Interests: Competing interests: GEM has served as an expert witness in litigations for plaintiffs exposed to thirdhand smoke. NB has been a consultant to companies that market or are developing smoking cessation medications and has been an expert witness in litigation against tobacco companies., (© Author(s) (or their employer(s)) 2024.

Background: With the aim of protecting minors, the World Health Organization has recommended classifying films with smoking scenes as unsuitable for children and adolescents. In recent years, films have increasingly been viewed via video streaming services - a trend which has been intensified by the COVID-19 pandemic - which poses new challenges for the protection of minors., Aim: To examine the frequency of smoking scenes in Netflix feature films and the age recommendations for Netflix productions with smoking scenes., Method: A total of 235 films that were made available for streaming exclusively by the Netflix platform in 2021 and 2022 were content coded in order to find out (1) how high the proportion of smoke-free films was in this film sample, (2) how often smoking scenes occurred in these films and (3) the proportion of films with smoke scenes classified as appropriate for young people in Germany and the USA. All films with an age rating of under 16 were considered suitable for children and young people., Results: Smoking scenes occurred in 113 of 235 analyzed films (48.1%). Of the 113 films with smoking scenes, 57 (50.4%) in Germany and 26 films (23.0%) in the USA were classified as youth films (p<0.001). A total of 3,310 smoking scenes were registered. Of these, 39.4% (n=1,303) were in films with youth ratings in Germany, and in Netflix USA this proportion was 15.8% (n=524)., Discussion: Smoking scenes are a common feature in Netflix movies. Neither in the US nor in Germany does Netflix adhere to the recommendations of the WHO Framework Convention on Tobacco Control to restrict access by young people to films depicting smoking. However, the protection of minors in the US is better than in Germany, since half of the Netflix films with smoking scenes in Germany were rated as suitable for minors, in the USA less than a quarter., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Objective: To investigate the tobacco-attributable burden on disease, medical costs, productivity losses and informal caregiving; and to estimate the health and economic gains that can be achieved if the main tobacco control measures (raising taxes on tobacco, plain packaging, advertising bans and smoke-free environments) are fully implemented in eight countries that encompass 80% of the Latin American population., Design: Markov probabilistic microsimulation economic model of the natural history, costs and quality of life associated with the main tobacco-related diseases. Model inputs and data on labour productivity, informal caregivers' burden and interventions' effectiveness were obtained through literature review, surveys, civil registrations, vital statistics and hospital databases. Epidemiological and economic data from January to October 2020 were used to populate the model., Findings: In these eight countries, smoking is responsible each year for 351 000 deaths, 2.25 million disease events, 12.2 million healthy years of life lost, US$22.8 billion in direct medical costs, US$16.2 billion in lost productivity and US$10.8 billion in caregiver costs. These economic losses represent 1.4% of countries' aggregated gross domestic products. The full implementation and enforcement of the four strategies: taxes, plain packaging, advertising bans and smoke-free environments would avert 271 000, 78 000, 71 000 and 39 000 deaths, respectively, in the next 10 years, and result in US$63.8, US$12.3, US$11.4 and US$5.7 billions in economic gains, respectively, on top of the benefits being achieved today by the current level of implementation of these measures., Conclusions: Smoking represents a substantial burden in Latin America. The full implementation of tobacco control measures could successfully avert deaths and disability, reduce healthcare spending and caregiver and productivity losses, likely resulting in large net economic benefits., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Tobacco endgame is a focal point of discussion at both national and international levels. We aimed to describe efforts related to achieving the tobacco endgame in the Republic of Korea, an exemplar of a country with endgame aspirations, and compare them with the efforts of other nations. We reviewed the tobacco endgame efforts of three nations considered tobacco control leaders: New Zealand (NZ), Australia and Finland. The efforts/attempts of each country were described using an endgame strategy category. The tobacco control leaders had explicit goals to achieve a smoking prevalence of <5% before a target date and had legislation and research centres for tobacco control and/or endgame. NZ is implementing a mixture of conventional and innovative endgame interventions; the others use incremental conventional approaches. In Korea, there has been an attempt to ban the sale and manufacture of combustible cigarettes. The attempt led to the filing of a petition, and a survey of adults showed 70% supported the legislation banning tobacco. The Korean government mentioned a tobacco endgame in a 2019 plan, yet a target and an end date were absent. The 2019 plan in Korea included incremental FCTC strategies. Practices in the leading countries show that legislation and research are key to ending the tobacco epidemic. The MPOWER measures must be strengthened, endgame objectives must be set and bold strategies must be adopted. Key endgame policies include those with evidence of effectiveness, such as retailer reductions., Competing Interests: Competing interests: No, there are no competing interests., (© Author(s) (or their employer(s)) 2024.

Introduction: One of the most vexing challenges to public health today is the menace of tobacco. Despite the large body of evidence indicating the vast scale of health hazards, tobacco use continues to be a major cause of preventable death. This study was conducted with the objective of quantifying the progress and challenges of the tobacco control policy of India., Methods: The Tobacco Control Scale (TCS) was used, which has a maximum score of 100 and assesses nine components including, price of cigarettes, smoke-free public and work places, spending on public information campaigns, comprehensive bans on advertising and promotion, large pictorial health warning labels, treatment to help smokers stop, illicit tobacco trade, tobacco industry interference and ratification of the WHO FCTC. The components of the TCS for India were scored based on data obtained from the WHO, Report on The Global Tobacco Epidemic, 2021 and the Cigarettes and Other Tobacco Products Act 2003 and their amendments and the Tobacco India 2023 country profile., Results: The total score for the tobacco control scale placed India at 65 points, scoring highest with respect to 'large pictorial health warning labels', and lower with respect to 'spending on public information campaigns', 'illicit tobacco trade' and 'price of cigarettes'., Conclusions: Strong tobacco control legislation and its equally robust implementation is an affirmative step in achieving the vision of the WHO-FCTC and empowering the world towards being tobacco free.

Smoke-free laws (SFL) are more effective with public support. This study investigated the smoking prevalence, public perceptions of smoking rules, and support for comprehensive SFL among 1047 people who smoke (PWS) and 206 people who do not smoke (PNS) aged ≥18 in the 2020 International Tobacco Control Malaysia Survey. Smoking prevalence was highest in nighttime entertainment venues (85.7%), non-air-conditioned eateries (49.7%), and indoor workplaces (34.6%). Respondents reported that smoking was banned in most indoor workplaces (81.7% PNS, 69.2% PWS), air-conditioned eateries (84.7% PNS, 75.7% PWS), and non-air-conditioned eateries (81.2% PNS, 78.7% PWS), but much less so in nighttime entertainment venues (30.1% PNS, 24.6% PWS). Support for comprehensive SFL in public venues was highest among PNS (≥84.9%) but still substantial among PWS (≥49.9%). PWS under 40, Malay, married, and aware of smoking rules supported SFL more. Robust SFL enforcement is essential in Malaysia to reduce secondhand smoke exposure in public places., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: GTF has served as an expert witness or consultant for governments defending their country’s policies or regulations in litigation and has served as a paid expert consultant to the Ministry of Health of Singapore in reviewing the evidence of plain/standardized packaging.

For several decades, Aotearoa New Zealand has maintained a relatively strict regulatory approach towards tobacco. In response to the significant impact of tobacco-related illnesses, many countries worldwide have worked to enhance tobacco control measures. These efforts include introducing plain tobacco packaging with graphic health warnings, improving access to smoking cessation services and offering supportive treatments for tobacco dependence. In December 2022, New Zealand enacted world-leading tobacco control legislation aimed at leading the nation towards a 'smokefree' future by 2025, a future where the smoking prevalence falls below 5 percent across all population groups. To achieve this goal, revolutionary measures were needed. These measures included denicotinising cigarettes, reducing the number of tobacco retail outlets, and implementing a generational ban on smoked products. Despite receiving support from academics, clinicians, leaders of local indigenous communities, and the general public, the sixth National-led coalition government remained resolute in repealing the law and did so through parliamentary urgency on 27 February 2024. The reversal of this health policy is anticipated to result in thousands of lives lost and widen life expectancy gaps between indigenous and non-indigenous populations. This decision, driven by political agenda objectives and interference from the tobacco industry, has not only impeded New Zealand's progress but also weakened global efforts in tobacco control., Competing Interests: Declaration of competing interest No conflicts of interest to declare., (Copyright © 2024 The Author(s).

Introduction: The harmful effects of first and secondhand smoking are well-established. Smoke-free laws aim at protecting nonsmokers. This study aimed to assess the impact of the 2013 total ban on indoor smoking in Chile on hospitalizations and deaths of major cardiovascular events., Aims and Methods: The logarithm of the monthly hospitalization and death rates, standardized by age for every 100 000 inhabitants, were estimated for ischemic heart disease, acute myocardial infarction, strokes, and a composite outcome of ischemic heart diseases (which includes acute myocardial infarction) and strokes. In addition, interrupted time series with synthetic control groups were used to assess changes in levels and trends after the intervention., Results: The total ban on indoor smoking caused significant reductions in death rates for the three diseases studied for age groups above 20 years old. In addition, there were substantial decreases in the post-intervention hospitalization rates for ischemic heart disease: for the 20-44 age group, the decrease was 8.7% compared to the pre-intervention period (p < .01). In comparison, such a reduction was 4% (p < .01) for the ≥65 age group. For acute myocardial infarction, the decrease was 11.5% (p < .01) for the 20-44 age group, while for stroke, it was a 1.2% (p < .01) decrease for the total population. It is estimated that the smoking ban averted 15.6% of the deaths compared with the synthetic control groups., Conclusions: The implementation of total smoke-free environments in Chile contributed to the reduction of mortality for main cardiovascular diseases. This study provides additional evidence of causality linking the policy to health outcomes., Implications: The total indoor smoking ban significantly affected age-standardized hospitalization and deaths. The number of deaths averted by this policy is estimated at approximately 4758 and 5256 for IHD and stroke, respectively, during the 2013-2017 period (15.6% fewer deaths than predicted by the synthetic control groups). The study contributes to the body of evidence that supports total indoor smoking bans., (© The Author(s) 2024.

The consumption of tobacco continues to be the greatest preventable health risk in Germany. Every year, more than 127,000 people die prematurely as a result of using tobacco - one in five new cases of cancer is a consequence of smoking. Germany's current tobacco control policy, consisting of advertising bans, the promotion of smoke-free environments, and an abstinence-only paradigm, are only able to initiate slow change. Other countries have shown how the number of smokers can be reduced and deaths prevented by integrating harm reduction as a complementary measure and providing a much more active support for people who want to quit. This article first presents the current situation and current measures in Germany. Then recommendations for changes to the current tobacco control policy in Germany are derived from a look at the United Kingdom, which is considered a pioneer throughout Europe with its tobacco control policy, as well as a summary of the current state of research., (© 2024.

Smoking and exposure to secondhand smoke pose a significant risk to the health of populations. Although this evidence is not new, the commitment of countries to implement laws aimed at controlling consumption and eliminating exposure to secondhand smoke is uneven. Thus, in North America or in Europe, locations like California or Ireland, are pioneers in establishing policies aimed at protecting the population against smoking and secondhand smoke. Identifying measures that have worked would help control this important Public Health problem in other countries that are further behind in tobacco control policies. In Spain, there has been almost 15 years of little political action in legislation oriented to control the tobacco epidemic. If we want to achieve the tobacco endgame, new legislative measures must be implemented. In this paper, we have elucidated tobacco control policies that could be implemented and show how different countries have done so., (© 2024. The Author(s).)

Background: Albania has one of the highest smoking prevalence in Europe especially among the youth. There is a lack of evidence in Albania, as well as in most of Eastern Europe and middle-income countries, regarding the effect of price on smoking experimentation., Objective: The study aims to assess the effect of price and tobacco control policies on youth smoking experimentation in Albania., Methods: We used microdata from the Global Youth Tobacco Survey in Albania for 2004, 2009, 2015 and 2020. We constructed a pseudo-longitudinal dataset and estimated a split-population model to assess the hazard of smoking experimentation., Results: Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females (p<0.001). Being male increases the odds for smoking experimentation by more than 50% as compared with females (p<0.001), whereas females appear to be more price sensitive. Peer and parent smoking are also important determinants for smoking experimentation. Introducing penalties for smokers and legal entities violating smoke-free policies implemented in 2014 is also associated with a lower hazard of smoking experimentation., Conclusion: Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females. A combination of increasing taxes and strengthening the rule of law to control tobacco use in public spaces, in addition to public awareness campaigns targeting both youth and smoking parents, could help to significantly reduce the probability of smoking experimentation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

This study aims to determinate the correlation between tobacco control policies (TCP) and the prevalence of tobacco use in the 32 Mexican states during the 2016-2017 period. This is an ecological study that measured TCP by the Tobacco Control Scale (TCS) which assigns a score (0-100) based on the level of these component's implementation: price, prohibition in public spaces, expenditures of public information campaigns, publicity prohibitions, health warnings, and treatments. We analyzed the associations between the TCS scores and prevalence of tobacco use extracted from the National Survey of Drug, Alcohol and Tobacco Consumption using Spearman correlations. Prevalence of daily smokers is negatively correlated with global TCS scores for adolescents (p = 0.026). Price showed similar negative correlations with daily prevalence in adolescents (p = 0.003), adults (p = 0.040), men (p < 0.006), and women (p = 0.040). Many Mexican states need to improve on tobacco control policies, especially targeting a key population: adolescents., (© 2024. The Author(s), under exclusive licence to Springer Nature Limited.)

Background: In response to the harm caused by tobacco use worldwide, the World Health Organization (WHO) World Health Assembly actioned the WHO Framework Convention on Tobacco Control (FCTC) in 2005. To help countries meet their FCTC obligations, the WHO introduced in 2008 the MPOWER policy package and by 2020 the FCTC had been ratified by 182 parties. The package consists of six evidence-based demand reduction smoking cessation policies to assist countries to achieve best practice. We used published evaluation results and replicated the published model to estimate current policy achievement and demonstrate the impact and equity of the MPOWER policy package in reducing the global number of smokers and smoking-attributable deaths (SADs) between 2007 and 2020., Methods: We replicated an evaluation model (the Abridged SimSmoke model) used previously for country impact assessments and validated our replicated reduction in SADs for policies between 2014 and 2016 against the published results. The replicated model was then applied to report on the country level SADs averted from achieving the highest level of implementation, that is best practice in MPOWER policies, between 2016 and 2020. The latest results were then combined with past published results to estimate the reduction in SADs since the commencement of the MPOWER policy package. Country level income status was used to investigate the equity in the uptake of MPOWER policies worldwide., Results: Identical estimates for SADs in 41 out of 56 MPOWER policies implemented in 43 countries suggested good agreement in the model replication. The replicated model overestimated the reduction in SADs by 159,800 (1.5%) out of a total of 10.5 million SADs with three countries contributing to the majority of this replication discrepancy. Updated analysis estimated a reduction of 8.57 million smokers and 3.37 million SADs between 2016 and 2020. Between 2007 and 2020, 136 countries had adopted and maintained at least one MPOWER policy at the highest level which was associated with a reduction in 81.0 million smokers and 28.3 million SADs. Seventy five percent of this reduction was in middle income countries, 20% in high income and less than 5% in low income countries., Conclusions: Considerable progress has been made by MPOWER policies to reduce the prevalence of smokers globally. However, there is inequality in the implementation and maintenance, reach and influence, and the number of SADs averted. Future research to modify the model could provide a more comprehensive evaluation of past and future progress in tobacco control policies, worldwide., (© 2024. The Author(s).)

In 2011, China implemented tougher driving-under-the-influence laws, which criminalized driving under the influence of alcohol for the first time and increased penalties. This paper provides the first comprehensive analysis of the effects of stricter drinking policies on men's smoking behavior by using data from the 2010 and 2012 waves of the China Family Panel Studies. The results show that stricter drinking policies reduced smoking initiation and the number of cigarettes smoked per day among men by reducing the frequency and quantity of alcohol consumption. Heterogeneity analyses show that the impact of the policy is more pronounced not only for men aged 41-55, but also for men who have higher educational qualifications, who are employed, or who are not members of the Communist Party., 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., (Copyright © 2024 Elsevier Ltd.

In 2020, California passed a flavored tobacco sales restriction (FTSR), but the tobacco companies filed a referendum, and the ban will not be implemented unless approved by voters in November 2022. This study examined the percentage of the California population covered by a city FTSR and identified groups more likely to be covered. Mean demographics as well as tobacco use and control measures were compared for California cities with ( n = 93) and without ( n = 389) a FTSR, and t tests were used to examine the differences. We calculated adjusted odds ratios using logistic regression models. City FTSR policies covered 20.7% of the California population. Adjusted predictors of having a FTSR included the American Lung Association tobacco control score (odds ratio [OR] = 1.27, 95% confidence interval [CI]: [1.17, 1.38]), voting democratic (OR = 1.06, 95% CI: [1.02, 1.10]). and having a lower adult smoking prevalence (OR = 0.84, 95% CI: [0.72, 0.99]). A state-level policy would cover all populations in California.

Objectives: People living in subsidised low-income housing are more likely to smoke and experience secondhand smoke exposure compared to the general population. While tobacco control interventions have yielded substantial population health benefits, people living in subsidised housing experience a greater burden of tobacco-related harms. We synthesised existing peer-reviewed and grey literature to determine tobacco control interventions that have been implemented in subsidised housing globally, and to understand their impact on smoking and secondhand smoke exposure., Methods: We searched five databases for peer-reviewed research, and Google Advanced for grey literature. We adhered to the JBI Scoping Review Methodology and Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist., Results: Fifty-seven sources met the eligibility criteria. The most common type of intervention was mandatory smoking bans covering all indoor spaces (n = 32), followed by cessation-focused interventions (n = 19). Interventions that indirectly addressed smoking were the least common (n = 6). Our findings suggest smoking bans can increase smoking cessation and reduce secondhand smoke exposure, especially if implemented alongside cessation support strategies., Conclusion: Tobacco control interventions targeting subsidised housing demonstrate positive effects on tobacco-related outcomes for residents and provide an important opportunity to address health disparities. Future research should examine the long-term impacts of the interventions, including potential unintended consequences, in varied subsidised housing contexts., Competing Interests: None declared.

Objective: To describe tobacco consumption and the compliance with the law on hospitality terraces in Barcelona., Method: Cross-sectional study by observation in a sample of 120 hospitality terraces in Barcelona. 30-minute observations were made using a standardized record sheet. The study variables were number of people smoking, number of cigarettes smoked, cigarette butts, socioeconomic status of the neighborhood, time of observation, consumption regulation, number of chairs and number of persons., Results: There were people smoking at the time of the observation in 97.5% of the terraces, with no differences according to socioeconomic level of the neighborhood or the regulation of the terrace. There was no compliance with the law in 100% of the terraces where smoking was banned., Conclusions: The widespread non-compliance with the current law indicates the need to implement a smoking ban without exceptions on hospitality terraces., (Copyright © 2024 SESPAS.

Aim: The recently passed Smokefree Environments and Regulated Products (Smoked Tobacco) Amendment Act has the potential to profoundly reduce smoking prevalence and related health inequities experienced among Māori. This study examined support for, and potential impacts of, key measures included within the legislation., Method: Data came from Wave 1 (2017-2019) of the Te Ara Auahi Kore longitudinal study, which was conducted in partnership with five primary health organisations serving Māori communities. Participants were 701 Māori who smoked. Analysis included both descriptive analysis and logistic regression., Results: More Māori participants supported than did not support the Smokefree 2025 (SF2025) goal of reducing smoking prevalence to below 5%, and the key associated measures. Support was greatest for mandating very low nicotine cigarettes (VLNCs). Participants also believed VLNCs would prompt high rates of quitting. Participants who had made more quit attempts or reported less control over their life were more likely to support VLNCs., Conclusion: There was support for the SF2025 goal and for key measures that could achieve it. In particular, VLNCs may have significant potential to reduce smoking prevalence among Māori. As part of developing and implementing these measures it will be important to engage with Māori who smoke and their communities., Competing Interests: Geoffrey T Fong has served as an expert witness or a consultant for governments defending their country’s policies or regulations in litigation.

This study evaluates the association between smoking rates and mortality from circulatory system diseases (CSD) after implementing a series of smoking bans in Macao (China). (1) Background: Macao phased in strict total smoking bans since 2012. During the past decade, smoking rates among Macao women have dropped by half. CSD mortalities in Macao also show a declining trend. (2) Method: Grey relational analysis (GRA) models were adopted to rank the importance of some key factors, such as income per capita, physician density, and smoking rates. Additionally, regressions were performed with the bootstrapping method. (3) Results: Overall, smoking rate was ranked as the most important factor affecting CSD mortality among the Macao population. It consistently remains the primary factor among Macao's female population. Each year, on average 5 CSD-caused deaths were avoided among every 100,000 women, equivalent to about 11.45% of the mean annual CSD mortality. (4) Conclusions: After the implementation of smoking bans in Macao, the decrease in smoking rate among women plays a primary role in the reduction in CSD mortality. To avoid excess CSD mortality due to smoking, Macao needs to continue to promote smoking cessation among the male population.

Background: Tobacco policies, including clean indoor air laws and cigarette taxes, increase smoking cessation in part by stimulating the use of cessation treatments. We explored whether the associations between tobacco policies and treatment use varies across sociodemographic groups., Methods: We used data from 62,165 U.S. adult participants in the 2003 and 2010/11 Tobacco Use Supplement to the Current Population Survey (TUS-CPS) who reported smoking cigarettes during the past-year. We built on prior structural equation models used to quantify the degree to which smoking cessation treatment use (prescription medications, nicotine replacement therapy, counseling/support groups, quitlines, and internet resources) mediated the association between clean indoor air laws, cigarette excise taxes, and recent smoking cessation. In the current study, we added selected moderators to each model to investigate whether associations between tobacco polices and smoking cessation treatment use varied by sex, race/ethnicity, education, income, and health insurance status., Results: Associations between clean indoor air laws and the use of prescription medication and nicotine replacement therapies varied significantly between racial/ethnic, age, and education groups in 2003. However, none of these moderation effects remained significant in 2010/11. Higher cigarette excise taxes in 2010/2011 were associated with higher odds of using counseling among older adults and higher odds of using prescription medications among younger adults. No other moderator reached statistical significance. Smoking cessation treatments did not mediate the effect of taxes on smoking cessation in 2003 and were not included in these analyses., Conclusions: Sociodemographic differences in associations between clean indoor air laws and smoking cessation treatment use have decreased from 2003 to 2010/11. In most cases, policies appear to stimulate smoking cessation treatment use similarly across varied sociodemographic groups., Competing Interests: Dr. Alexander is past Chair of FDA’s Peripheral and Central Nervous System Advisory Committee; has served as a paid advisor to IQVIA; is a Principal and holds equity in Monument Analytics, a health care consultancy whose clients include the life sciences industry as well as plaintiffs in opioid litigation; and is a member of OptumRx’s National P&T Committee.

Objective: Active smoking among patients undergoing interventions for intermittent claudication (IC) is associated with poor outcomes. Notwithstanding, current levels of active smoking in these patients are high. State-level tobacco control policies have been shown to reduce smoking in the general US population. We evaluated whether state cigarette taxes and 100% smoke-free workplace legislation are associated with active smoking among patients undergoing interventions for IC., Methods: We queried the Vascular Quality Initiative database for peripheral endovascular interventions, infrainguinal bypasses, and suprainguinal bypasses for IC. Active smoking at the time of intervention was defined as smoking within one month of intervention. We implemented difference-in-differences analysis to isolate changes in active smoking owing to cigarette taxes (adjusted for inflation) and implementation of smoke-free workplace legislation. The difference-in-differences models estimated the causal effects of tobacco policies by adjusting for concurrent temporal trends in active smoking unrelated to cigarette taxes or smoke-free workplace legislation. The models controlled for age, sex, race/ethnicity, insurance type, diabetes, chronic obstructive pulmonary disease, state, and year. We tested interactions of taxes with age and insurance., Results: Data were available for 59,847 patients undergoing interventions for IC in 25 states from 2011 to 2019. Across the study period, active smoking at the time of intervention decreased from 48% to 40%. Every $1.00 cigarette tax increase was associated with a 6-percentage point decrease in active smoking (95% confidence interval, -10 to -1 percentage points; P = .02), representing an 11% decrease relative to the baseline proportion of patients actively smoking. The effect of cigarettes taxes was greater in older patients and those on Medicare. Among patients aged 60 to 69 and 70 to 79 years, every $1.00 tax increase resulted in 14% and 21% reductions in active smoking relative to baseline subgroup prevalences of 53% and 29%, respectively (P < .05 for both); however, younger age groups were not affected by tax increases. Among insurance groups, only patients on Medicare exhibited a significant change in active smoking with every $1.00 tax increase (an 18% decrease relative to a 33% baseline prevalence; P = .01). The number of states implementing smoke-free workplace legislation increased from 9 to 14 by 2019; however, this policy was not significantly associated with active smoking prevalence. At follow-up (median, 12.9 months), $1.00 tax increases were still associated with decreased smoking prevalence (a 25% decrease relative to a 33% baseline prevalence; P < .001)., Conclusions: Cigarette tax increases seem to be an effective strategy to decrease active smoking among patients undergoing interventions for IC. Older patients and Medicare recipients are the most responsive to tax increases., (Copyright © 2020 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

Introduction: Smoking among young adults is often associated with social contexts and alcohol use. Although many countries, including New Zealand, have prohibited smoking inside licensed premises, outdoor areas have enabled smoking and alcohol co-use to persist. We examined whether and how outdoor bar areas facilitate and normalize young adult smoking and explored potential policy implications., Methods: We conducted in-depth interviews with 22 young adults who had recently smoked in a New Zealand bar or nightclub and investigated how physical design attributes (atmospherics) influenced experiences of smoking in outside bar settings. We used qualitative description to identify recurring accounts of the outdoor bar environment and thematic analysis to explore how participants experienced the bar in relation to smoking., Results: Participants valued outdoor smoking areas that were comfortable and relaxing, and saw attributes such as seating, tables, heating, protection from inclement weather, and minimal crowding, as important. We identified four themes; these explained how participants used smoking to gain respite and make social connections, showed how bar settings enabled them to manage smoking's stigma, and identified potential policy measures that would decouple smoking and alcohol co-use., Conclusions: Evidence bar environments facilitate and normalize smoking among young adults questions whether smokefree policies should be expanded to include all bar areas. Introducing more comprehensive smokefree outdoor policies could reduce the influence of design attributes that foster smoking while also reframing smoking as outside normal social practice., Implications: Bar environments contain many stimuli that cue and reinforce smoking and integrate smoking into social experiences. Expanding smokefree bar settings to include outdoor areas would reduce exposure to these stimuli, decrease opportunities for casual smoking, help maintain young people's smokefree status, and support longer-term goals of sustained reductions in smoking prevalence., (© The Author(s) 2020.

In 2019, San Francisco, California, prohibited the sale of electronic cigarettes lacking US Food and Drug Administration authorization. JUUL then promoted a ballot initiative (Proposition C) to replace San Francisco's e-cigarette legislation with legislation JUUL wrote that required future legislation to be approved by the voters. JUUL promoted Proposition C as a way to reduce youth e-cigarette use while allowing adult choice.Health groups argued that JUUL's measure could nullify San Francisco's prohibition on selling flavored tobacco products. Health groups benefitted from having an established campaign network that recently defended the flavor ban. They successfully framed Proposition C as a tobacco industry ploy to undo San Francisco's e-cigarette regulations, particularly the prohibition on selling flavored tobacco products. JUUL ended its campaign on September 30, 2019, and the measure failed on election day, with 82% voting against it.Lessons learned from the campaign include the importance of framing an industry initiative as a threat to local public health lawmaking and the potential for the e-cigarette issue to attract parents as new leaders and engage a powerful constituency to support tobacco control measures.

Substantial global effort has been devoted to curtailing the tobacco epidemic over the past two decades, especially after the adoption of the Framework Convention on Tobacco Control 1 by the World Health Organization in 2003. In 2015, in recognition of the burden resulting from tobacco use, strengthened tobacco control was included as a global development target in the 2030 Agenda for Sustainable Development 2 . Here we show that comprehensive tobacco control policies-including smoking bans, health warnings, advertising bans and tobacco taxes-are effective in reducing smoking prevalence; amplified positive effects are seen when these policies are implemented simultaneously within a given country. We find that if all 155 countries included in our counterfactual analysis had adopted smoking bans, health warnings and advertising bans at the strictest level and raised cigarette prices to at least 7.73 international dollars in 2009, there would have been about 100 million fewer smokers in the world in 2017. These findings highlight the urgent need for countries to move toward an accelerated implementation of a set of strong tobacco control practices, thus curbing the burden of smoking-attributable diseases and deaths.

Background: Raising the minimum legal age (MLA) of tobacco sales from 18 to 21 (Tobacco 21 [T21]) has recently been implemented nationwide as a method to reduce tobacco use, but empirical data on youth knowledge of T21 policies and related pathways to tobacco use are limited., Methods: Data were collected from the 2018 Kansas Communities That Care Student Survey. Knowledge of the MLA was compared between T21 and non-T21 regions using a quasi-experimental design. Logistic regression and mediation analysis were conducted to assess the association between knowledge of the MLA, influencing factors, and intention to use tobacco., Results: Of 16 949 students (aged between 11 and 18) completing the T21 survey, fewer students responded correctly about the MLA in T21 than in non-T21 regions (37.4% vs. 46.3% responded correctly, 27.6% vs. 24.2% responded incorrectly, respectively). In T21 regions, Hispanics and students who support T21 were more likely to respond correctly about the MLA. Among current non-tobacco users in T21 regions, students who responded correctly about the MLA were less likely to report intention to use tobacco (adjusted odds ratio [AOR] = 0.7, 95% confidence interval [CI]: [0.6-0.8]) than those who responded incorrectly. The pathway from knowledge of the MLA to intention to use tobacco was significantly mediated by increased support for T21 (p = .002), perceived difficulty in accessing cigarettes (p = .042), and reduced susceptibility to peer influence (p = .027)., Conclusions: Knowledge of the MLA was inversely associated with intention to use tobacco among youth. Educational campaigns to raise awareness and support for T21 among youth may improve the impact of T21 policies., Implications: This study examined youth knowledge of the MLA to purchase tobacco products, and whether knowledge of the MLA was associated with reduced intention to use tobacco. It also examined other influencing factors (eg, perceived support for T21) and potential mediation pathways linking knowledge of the MLA with intention to use tobacco. Given the nationwide adoption of T21, educational campaigns to promote knowledge of the policy may improve its impact., (© The Author(s) 2020.

Introduction: Under the US Family Smoking Prevention and Tobacco Control Act, the US Food and Drug Administration (FDA) has the authority to implement graphic warning labels (GWLs) on cigarette packages. Neither the original labels proposed by the FDA nor the revised labels include a source to indicate sponsorship of the warnings. This study tests the potential impact of adding a sponsor to the content of GWLs., Methods: We recruited adult smokers (N = 245) and middle-school youth (N = 242) from low-income areas in the Northeastern US. We randomly assigned participants to view one of three versions of the original FDA-proposed warning labels in a between-subjects experiment: no sponsor, "US Food and Drug Administration," or "American Cancer Society" sponsor. We tested the effect of varying sponsorship on source attribution and source credibility., Results: Compared to unsponsored labels, FDA sponsorship increased source attributions that the FDA sponsored the labels among both middle-school, largely nonsmoking youth and adult smokers. However, sponsorship had no effect on source credibility among either population., Conclusions: We found no evidence that adding FDA as the source is likely to boost source credibility judgments, at least in the short term; though doing so would not appear to have adverse effects on credibility judgments. As such, our data are largely consistent with the Tobacco Control Act's provisions that allow, but do not require, FDA sponsorship on the labels., Implications: This study addresses the FDA's regulatory efforts by informing the possible design and content of future cigarette warning labels. Our results do not offer compelling evidence that adding the FDA name on GWLs will directly increase source credibility. Future work may test more explicit FDA source labeling and continue to examine the credibility of tobacco message content among high-priority populations., (© The Author(s) 2020.

Objective: In this study, we aimed to clarify the transition to the implementation of smoking prohibition at eating and drinking establishments one year before and after April 2020, the time when they became "nonsmoking" in principle following the implementation of the amendment bill for the Health Promotion Act of Japan., Methods: The total number of nonsmoking/smoking eating and drinking establishments by industry were obtained using the data from "Tabelog ® ." The number of people who tested positive for COVID-19 by the polymerase chain reaction test on the day of the survey nationwide and the bankruptcy status of the companies (eating and drinking establishments, etc.) for each month were ascertained., Results: In 2020, a state of emergency was declared owing to the increase in the number of people positive for COVID-19, and many eating and drinking establishments went bankrupt. Despite these circumstances, the number of nonsmoking eating and drinking establishments exceeded that of smoking establishments in March 2020 and continued to increase thereafter. Additionally, the number of nonsmoking "restaurants" increased and exceeded that of smoking restaurants in June 2020. The number of nonsmoking "cafes" already exceeded that of smoking "cafes" at the beginning of this survey and continued to increase. The number of nonsmoking "bars" increased, but that of smoking "bars" remained high., Conclusion: It is necessary to promote measures against passive smoking while paying attention to the trends for different types of eating and drinking establishments, rather than considering all establishments together.

Introduction: Within the context of the World Health Organization Framework Convention on Tobacco Control Protocol to Eliminate Illicit Trade in Tobacco Products and the impending revision of the European Union (EU) directive on tobacco excise rules we assessed whether cigarettes price is linked to being offered illicit cigarettes., Methods: We combined data being offered illicit cigarettes from the 2015 Special Eurobarometer Survey on Illicit Tobacco (N = 27,672) with area-level data on Gross Domestic Product, unemployment, perceived corruption, and sharing a border with a non-European Economic Area (non-EEA) state. We used the 2015 Weighted Average Price of cigarettes (WAP), which reflects the average price of a cigarette pack in each Member State. We assessed associations between prices and illicit trade using three-level ordered regression models., Results: About 19.6% of respondents reported ever being offered illicit cigarettes, 6.4% repeatedly. In fully adjusted models WAP was not associated with being more likely to have been offered illicit market cigarettes more often (adjusted odds ratio = 1.02, 95% confidence interval: 0.91; 1.15). Sharing a border with a non-EEA Member State was associated with increased likelihood of reporting being offered illicit cigarettes more often (1.73, 1.26; 2.39)., Conclusion: This study found no significant association between cigarette prices and reporting being offered illicit cigarettes; sharing a border with a non-EEA Member State was linked to illicit trade. This study adds to evidence that increasing prices of cigarettes are not associated with illicit trade and that the focus should remain on securing supply chains, including through features such as independent traceability systems., Implications: After adjusting for individual and regional factors, we did not identify an association between prices of cigarettes and likelihood of reporting being offered illicit cigarettes in the EU. Sharing a border with a non-EEA state, however, was associated with increased likelihood of reporting being offered illicit cigarettes more often. This study adds to evidence that increasing taxes and prices of cigarettes are not a driver of illicit trade and that policies should maintain their focus on securing the supply chain., (© The Author(s) 2020.

Even though 90% of the world's population is covered by the World Health Organization's Framework Convention on Tobacco Control, it is estimated that only one-fifth (21%) and half (49%) of the countries that ratified this convention will achieve the target of reducing tobacco use by 30 % among men and women respectively in 2025. Over the past decade, there has been an increasing trend in the use of electronic cigarettes or e-cigarettes for recreational use as well as smoking cessation. In concurrence with the increasing use of e-cigarettes among smokers of different age groups, nations have developed relevant national regulations on its sale, advertisement, packaging, product regulation, taxation, and surveillance. The countries of the Gulf Cooperation Council (GCC) region have also witnessed several legislations, at varying extent, related to the use of electronic cigarettes. However, the evidence on the use of electronic nicotine delivery systems remains scarce in the GCC region. Thus, further research on this emerging public health issue is warranted to generate the evidence necessary for the formulation of comprehensive tobacco control laws and effective prevention strategies., .

Introduction: Many European schools implement smoke-free school policies (SFSPs). SFSPs may decrease adolescent smoking by causing adolescents to perceive stronger antismoking norms, yet there exists no quantitative evidence that indicates for which norms and for whom such effects may occur. This study therefore assessed to what extent adolescents' perceived antismoking norms among best friends, teachers, and society at large were associated with SFSPs, and whether these associations were moderated by adolescents' level of school connectedness., Aims and Methods: Survey data were collected in 2016/2017 on 10,653 adolescents aged 14-16 years old and 315 staff members in 55 schools from seven European cities. Associations of adolescent-perceived SFSPs and staff-reported SFSPs with best friend, teacher, and societal antismoking norms were estimated in multilevel logistic regression models, adjusted for demographics and school-level smoking prevalence. We tested for interaction between school connectedness and SFSPs., Results: Adolescent-perceived SFSPs were positively associated with antismoking norms by teachers (odds ratio [OR]: 1.46, 95% confidence interval [CI]: 1.15-1.85), were negatively associated with antismoking norms by best friends (OR: 0.81, 95% CI: 0.67-0.99), but were not significantly associated with antismoking norms by society at large (OR: 0.87, 95% CI: 0.74-1.02). All interaction tests between adolescent-perceived SFSPs and school connectedness were nonsignificant. Staff-reported SFSPs were not associated with any norm and showed no significant interaction with school connectedness., Conclusions: We found that SFSPs are associated with adolescents' perception of more antismoking norms by teachers, but less antismoking norms by best friends, irrespective of adolescents' level of school connectedness., Implications: Smoke-free school policies, just as many other tobacco control policies, are assumed to foster adolescents' perception of antismoking norms. Still, current evidence does not demonstrate which antismoking norms may be influenced by SFSPs and whether this influence is equal for adolescents with different levels of school connectedness. This study suggests that SFSPs foster adolescents' perception of antismoking norms by teachers, but may concurrently lead to the perception of less antismoking norms by best friends, irrespective of adolescents' school connectedness. SFSPs may therefore need to be complemented with interventions that target antismoking norms in adolescent peer groups., (© The Author(s) 2019.

Introduction: UK countries implemented smoke-free public places legislation and increased the legal age for tobacco purchase from 16 to 18 years between 2006 and 2008. We evaluated the immediate and long-term impacts of these UK policy changes on youth smoking uptake and inequalities therein., Aims and Methods: We studied 74 960 person-years of longitudinal data from 14 992 youths (aged 11-15 years) in annual UK household surveys between 1994 and 2016. Discrete-time event history analyses examined whether changes in rates of youth smoking transitions (initiation, experimentation, and escalation to daily smoking or quitting) or their inequalities (by parental education) were associated with policy implementation. Parallel analyses examined smoke-free legislation and the change in legal age. We interpret the results as a combined effect of the two pieces of legislation as their implementation dates were too close to identify separate effects. Models were adjusted for sex, age, UK country, historical year, tobacco taxation, and e-cigarette prevalence, with multiple imputation for missing data., Results: For both policies, smoking initiation reduced following implementation (change in legal age odds ratio [OR]: 0.67; 95% confidence interval [CI]: 0.55 to 0.81; smoke-free legislation OR: 0.68; 95% CI: 0.56 to 0.82), while inequalities in initiation narrowed over subsequent years. The legal age change was associated with annual increases in progression from initiation to occasional smoking (OR: 1.26; 95% CI: 1.07 to 1.50) and a reduction in quitting following implementation (OR: 0.57; 95% CI: 0.35 to 0.94). Similar effects were observed for smoke-free legislation but CIs overlapped the null., Conclusions: Policies such as these may be highly effective in preventing and reducing socioeconomic inequalities in youth smoking initiation., Implications: UK implementation of smoke-free legislation and an increase in the legal age for tobacco purchase from 16 to 18 years were associated with an immediate reduction in smoking initiation and a narrowing of inequalities in initiation over subsequent years. While the policies were associated with reductions in the initiation, progression to occasional smoking increased and quitting decreased following the legislation., (© The Author(s) 2020.

Background: Pregnant women's exposure to secondhand smoke is a very serious health issue in China. The purpose of our research is to identify factors that predict the probability of exposure to secondhand smoke among pregnant women from the perspective of a family-based open system., Methods: From September 2014 to August 2015, Urumqi City, Shihezi City, and Shawan County-level City were sampled according to population characteristics. A revised structured questionnaire based on family resources was adapted for use in this study. Questionnaires were collected via convenience sampling at the hospitals with the largest number of local antenatal clients. A total of 1249 pregnant women of age 18-51 years were investigated. Descriptive statistics were calculated to characterize the participants and study variables. Binary logistic regression was performed to assess the impact of family resources corresponding variables on the likelihood that participants would be exposed to SHS. Both unadjusted and adjusted odds ratios (OR/AOR) [with 95% confidence intervals (CI)] were reported., Results: The secondhand smoke exposure rate found in this study was 54.6%. Having good knowledge of the dangers of secondhand smoke had no effect on reducing the prevalence of exposure (P > 0.05). Even pregnant women whose husbands who did not use tobacco or never smoked nearby had a risk of exposure to secondhand smoke [adjusted odds ratio (AOR) 1.568, 95% CI 1.205-2.041] when the data were adjusted for age, gravidity, gestational weeks, knowledge of the dangers of secondhand smoke, location, and work status. Home smoking bans were confirmed to be an important protective factor (AOR 1.710, 95% CI 1.549-1.918); however, only one-third (33.5%) of participants reported having a smoking ban at home. Religion (mainly Islam), as a special external family resource, was a protective factor that reduced secondhand smoke exposure in pregnant women (AOR 0.399, 95% CI 0.312-0.510)., Conclusions: The effect of family resources on tobacco control should be considered in the development of effective and enduring strategies for indoor smoking bans and smoking cessation.
