How can hospitals change practice to better implement smoking cessation interventions? A systematic review.

Smoking cessation reduces the risk of death, improves recovery, and reduces the risk of hospital readmission. Evidence and policy support hospital admission as an ideal time to deliver smoking-cessation interventions. However, this is not well implemented in practice. In this systematic review, the authors summarize the literature on smoking-cessation implementation strategies and evaluate their success to guide the implementation of best-practice smoking interventions into hospital settings. The CINAHL Complete, Embase, MEDLINE Complete, and PsycInfo databases were searched using terms associated with the following topics: smoking cessation, hospitals, and implementation. In total, 14,287 original records were identified and screened, resulting in 63 eligible articles from 56 studies. Data were extracted on the study characteristics, implementation strategies, and implementation outcomes. Implementation outcomes were guided by Proctor and colleagues' framework and included acceptability, adoption, appropriateness, cost, feasibility, fidelity, penetration, and sustainability. The findings demonstrate that studies predominantly focused on the training of staff to achieve implementation. Brief implementation approaches using a small number of implementation strategies were less successful and poorly sustained compared with well resourced and multicomponent approaches. Although brief implementation approaches may be viewed as advantageous because they are less resource-intensive, their capacity to change practice in a sustained way lacks evidence. Attempts to change clinician behavior or introduce new models of care are challenging in a short time frame, and implementation efforts should be designed for long-term success. There is a need to embrace strategic, well planned implementation approaches to embed smoking-cessation interventions into hospitals and to reap and sustain the benefits for people who smoke.

Are older adults' home exposures to secondhand smoking during earlier life stages associated with current health status and life satisfaction in China? A multilevel approach.

Secondhand smoking (SHS) has become a critical challenge in Chinese society, and progress on SHS prevention remains unknown. There is little knowledge targeting Chinese older adults generally to investigate the associations between SHS exposure experiences during earlier life stages and health-related measurements. Using cross-sectional data from a nationally representative data set, the 2014 wave of the Chinese Longitudinal Healthy Longevity Survey (n = 4,414), multilevel logistic regression models with random effects for Chinese provinces were used for analyses. Two health-related measurements included self-reported health status and life satisfaction. All regression models included the same set of predictors and covariates with socioeconomic factors and basic biological information. Approximately 40% and 47% of older adults reported SHS exposure in childhood and in younger adulthood at home, respectively. Older adults with SHS exposure in childhood had lower odds of reporting better health status, compared with those who did not have such exposure (adjusted odds ratio [AOR] = 0.69, 95% CI [0.55, 0.86], p < .01). However, life satisfaction was not associated with any SHS exposure experiences. Policy makers and public health practitioners should continue to investigate the long-term effect of SHS exposure on human health, including older adults. Policy regarding SHS prevention should be enhanced.

Characteristics Associated with Smoking Among Patrons of Three Philadelphia Parks.

To create healthy public spaces, Philadelphia prohibits smoking in city-owned and operated parks. Identifying the prevalence and characteristics of smoking in Philadelphia Parks would be useful for monitoring purposes; yet no studies have collected this data. This study identified the prevalence and characteristics of smoking among adult patrons entering three Philadelphia Parks (Washington Square Park, Independence Square Park, and Louis Kahn Park). During May and June 2016, we observed patrons entering the parks on Thursday afternoons. We used handheld electronic devices to categorize patrons by smoking status, age, gender, and tobacco product. We used logistic regression to assess the association of these variables with smoking. We observed 4822 people, of which 10.6% were children. Smoking was noted among 2.6% of adults in Washington Square Park, 2.6% of adults in Independence Square Park, and 7.7% of adults in Louis Kahn Park. Patronizing Louis Kahn Park was associated with greater likelihood of smoking (OR 3.11, CI 1.77-5.46) compared to Washington Square. Males were more likely than females to smoke (OR 1.45, CI 1.01-2.09). Higher likelihood of smoking among males concurs with previous studies. Higher prevalence in Louis Kahn Park may be due to differences in park patron demographics compared to other parks. Results could be used as a baseline for periodic monitoring of smoking in parks in order to inform implementation of the smoke-free park policy in Philadelphia.

The subversion of Mill and the ultimate aim of nursing.

This is lightly edited and referenced version of a presentation given at the 20th International Philosophy of Nursing conference in Quebec on 23rd August 2016. Philosophical texts are not given the same prominence in nurse education as their more valued younger sibling, primary research evidence, but they can influence practice through guidelines, codes and espoused values. John Stuart Mill's harm principle, found in On Liberty, is not a universal law, and only a thoroughgoing libertarian would defend it as such, though it, or its remnants, can be seen can be seen in policy documents. But its influence is weakening. Smoking bans in enclosed spaces were initially justified with other-regarding considerations, but judgements from unsuccessful legal challenges from patients in UK psychiatric hospitals rely on preventing harm to the smoker, even when smoking outside, which does not harm others. In the wake of legislation, no-smoking policies enacted by hospitals are becoming more aggressive, banning smoking both inside and outside, and extending the use of power gained through employment to prevent nurses assisting patients enjoy a lawful habit. Mill's dictum has been subverted, and this speaks to the fundamental purpose of nursing. Should nurses collude and willingly exert their power for their version of the good of the patient? Or should they instead reaffirm values that support and facilitate life choices made by autonomous people? The paper supports the latter option, and this has wider application for nursing which can be illuminated, if not settled, by revisiting Mill and his famous dictum.

Smoking and attitudes toward smoking policy at a University in Egypt.

To assess smoking behavior, knowledge of smoking harm, and attitudes toward campus smoking policy at an Egyptian university, an online survey of students, staff, and faculty was conducted (N = 992). The smoking prevalence of 38% among men was in line with Egypt's national average, but the smoking prevalence among women of 20% was much higher than the national average. Smoking status influenced beliefs about smoking harm and attitudes toward smoking policy, with nonsmokers having stronger beliefs about the harm of smoking and showing stronger support for smoking regulations than smokers. Smokers were more knowledgeable about smoking policy than were nonsmokers and differed slightly in their preferences for smoking policy enforcement strategies. These findings contribute to our understanding of how to tailor college smoking policy and programs to an Egyptian context.

[Smoking at workplace - Legislation and health aspect of exposure to second-hand tobacco smoke]. / Palenie tytoniu w miejscu pracy - prawny i zdrowotny aspekt biernego narazenia na dym tytoniowy.

Tobacco smoke contains thousands of xenobiotics harmful to human health. Their irritant, toxic and carcinogenic potential has been well documented. Passive smoking or exposure to second-hand smoke (SHS) in public places, including workplace, poses major medical problems. Owing to this fact there is a strong need to raise workers' awareness of smoking-related hazards through educational programs and to develop and implement legislation aimed at eliminating SHS exposure. This paper presents a review of reports on passive exposure to tobacco smoke and its impact on human health and also a review of binding legal regulations regarding smoking at workplace in Poland. It has been proved that exposure to tobacco smoke during pregnancy may lead to, e.g., preterm delivery and low birth weight, sudden infant death syndrome, lung function impairment, asthma and acute respiratory illnesses in the future. Exposure to tobacco smoke, only in the adult age, is also considered as an independent risk factor of cardiovascular diseases, acute and chronic respiratory diseases and cancer. Raising public awareness of tobacco smoke harmfulness should be a top priority in the field of workers' health prevention. Occupational medicine physicians have regular contacts with occupationally active people who smoke. Thus, occupational health services have a unique opportunity to increase employees and employers' awareness of adverse health effects of smoking and their prevention.

Should we bother with second-hand smoke exposure if smoking is on track? A poorly explored discrepancy in Denmark.

The recognition of the serious health-damaging effects of tobacco smoke exposure has initiated several preventive programmes on the national and international levels worldwide. In the last decade, a considerable decrease in the prevalence of active smoking was observed in Denmark, changing the country from a poor to a favourable position in comparison to other EU countries. However, second-hand tobacco smoke exposure, especially in homes, still ranks Denmark among the problematic countries in Europe. This poorly recognised and studied discrepancy calls for further research and effective targeted interventions on population level.

The economic cost of direct smoking in South Korea.

Background: Smoking not only causes negative health outcomes for individuals but also causes an economic burden to society. This study estimated the socioeconomic costs of direct smoking in South Korea in 2020. Methods: We used the prevalence-based cost-of-illness approach to estimate the sum of the direct (medical, transportation, and caregiving) and indirect (productivity loss due to health service utilization and premature death) costs of 41 smoking-related diseases. We assumed that diseases with death-based hazard ratios greater than 1.0 were related to smoking and used them in cost estimation. Results: The socioeconomic cost of direct smoking in Korea was USD 10.9 billion in 2020, accounting for 0.67 % of the gross domestic product and 8.0 % of current health expenditures. The direct cost was USD 4,172 million and the indirect cost was USD 6,753 million. The cost of productivity loss due to premature death took up the largest amount of the total cost, accounting for 52.3 %. The amount attributed to males accounted for 90.4 % of the overall cost, totaling to USD 9,877 million. This is attributable to higher smoking rates and higher medical costs in men. Cancer costs accounted for 40.0 % of the total cost, causing the greatest burden of diseases. Conclusion: Direct smoking imposed a harmful and heavy economic burden on South Korea. Our estimate provides the latest evidence on the financial burden of smoking and strengthens the case for strong tobacco control policies and interventions.

Factors influencing adolescent experimental and current smoking behaviors based on social cognitive theory: A cross-sectional study in Xiamen.

Introduction: China has the largest youth population in the world. To better implement the Smoke-free School Initiative, this study aims to examine the protective and risk factors for different smoking behaviors (never smoked, experimental smoking, and current smoking) among school adolescents based on social cognitive theory. Methods: This research was a secondary analysis of a cross-sectional survey of middle schools in Huli District of Xiamen, China. The final sample consisted of 1937 participants with an average age of 15.41 (SD = 1.64). Descriptive statistics were used to summarize the sociodemographic characteristics of the sample. Multivariate multinomial logistic regression analysis was performed using four models. Results: Of the respondents, 1685 (86.99%) were never smokers, 210 (10.84%) were experimental smokers, and 42 (2.17%) were current smokers. Social norms, positive outcome expectations, anti-smoking self-efficacy, and attitudes toward control tobacco policies were associated with adolescents' smoking behaviors. The number of smoking family members, classmates smoking, the perception that smoking is cool and attractive, and attitudes toward control tobacco policies were the predictors of current smoking behavior (p < 0.05). In contrast, friends smoking and individual and social relationship motivation were associated with only experimental smoking (p < 0.05). Discussion: The relationship of social norms, positive outcome expectations, anti-smoking self-efficacy, and attitudes toward control tobacco policies varied across smoking behaviors. Family, school, society and the government need to cooperate in prevention and intervention programs for adolescent smoking. The relationships between these factors and adolescents' different smoking behaviors needs to be further verified.

Prevalence and Predictors of Hardcore Smoking in India-: Findings from the Global Adult Tobacco Survey (2016-2017).

BACKGROUND: Hardcore smokers are of significant public health concern having a greater risk of developing tobacco-related diseases. OBJECTIVE: This study aimed to identify burden of hardcore smokers, its distribution, and determinants in India. SUBJECTS AND METHODS: Analysis of Global Adult Tobacco Survey India 2016-2017 data was carried out. Hardcore smoking was defined when the following criteria were fulfilled - current daily cigarette smoking for at least 5 years, no quit attempt in past 12 months, no intention to quit in next 12 months, and time to first smoke within 30 min of waking up. Independent variables included sociodemographic, knowledge of side effects, indoor smoking policy, and age of smoking initiation. Multivariable logistic regression was carried out, with adjustment for clustering, stratification, and sampling weight. RESULTS: Proportion of hardcore smoking among the general population and current daily smokers were 3.43% and 32.3%, respectively. In the adjusted model, it was found to be significantly associated with increasing age, earlier initiation of daily smoking, tribal caste, and unfavorable indoor smoking policy. CONCLUSION: Tobacco control strategies should be modified to tackle these issues, especially early age of initiation of daily smoking and indoor smoking policy.

Campus Smoking Policies and Smoking-Related Twitter Posts Originating From California Public Universities: Retrospective Study.

BACKGROUND: The number of colleges and universities with smoke- or tobacco-free campus policies has been increasing. The effects of campus smoking policies on overall sentiment, particularly among young adult populations, are more difficult to assess owing to the changing tobacco and e-cigarette product landscape and differential attitudes toward policy implementation and enforcement. OBJECTIVE: The goal of the study was to retrospectively assess the campus climate toward tobacco use by comparing tweets from California universities with and those without smoke- or tobacco-free campus policies. METHODS: Geolocated Twitter posts from 2015 were collected using the Twitter public application programming interface in combination with cloud computing services on Amazon Web Services. Posts were filtered for tobacco products and behavior-related keywords. A total of 42,877,339 posts were collected from 2015, with 2837 originating from a University of California or California State University system campus, and 758 of these manually verified as being about smoking. Chi-square tests were conducted to determine if there were significant differences in tweet user sentiments between campuses that were smoke- or tobacco-free (all University of California campuses and California State University, Fullerton) compared to those that were not. A separate content analysis of tweets included in chi-square tests was conducted to identify major themes by campus smoking policy status. RESULTS: The percentage of positive sentiment tweets toward tobacco use was higher on campuses without a smoke- or tobacco-free campus policy than on campuses with a smoke- or tobacco-free campus policy (76.7% vs 66.4%, P=.03). Higher positive sentiment on campuses without a smoke- or tobacco-free campus policy may have been driven by general comments about one's own smoking behavior and comments about smoking as a general behavior. Positive sentiment tweets originating from campuses without a smoke- or tobacco-free policy had greater variation in tweet type, which may have also contributed to differences in sentiment among universities. CONCLUSIONS: Our study introduces preliminary data suggesting that campus smoke- and tobacco-free policies are associated with a reduction in positive sentiment toward smoking. However, continued expressions and intentions to smoke and reports of one's own smoking among Twitter users suggest a need for more research to better understand the dynamics between implementation of smoke- and tobacco-free policies and resulting tobacco behavioral sentiment.

Air quality at venues of mixed smoking policies in Kazakhstan.

INTRODUCTION: Enclosed designated smoking areas (DSAs) and smoking zones are allowed in food-serving venues in Kazakhstan. Air quality in smoke-free food-serving venues, in venues with smoking throughout, in those with DSAs and those with smoking zones, is not fully understood. METHODS: A cross-sectional study with aim to evaluate PM2.5 concentrations in the venues with mixed smoking was conducted from September to October 2017 in Almaty, the largest city of Kazakhstan. A total of 44 rooms within the selected 29 venues were evaluated: 100% smoke-free (5), non-smoking zones (7), smoking zones (7), non-smoking venues with DSAs (8), venues that allow smoking throughout (9), and DSAs (8). Real-time PM2.5 measurement was conducted by TSI SidePak AM510 Personal Aerosol Monitor and used to rank health-risk assessment using the Air Quality Index developed by the U.S. Environmental Protection Agency. RESULTS: Smoke-free food-serving venues had moderate levels of air quality with mean PM2.5 of 26.2 µg/m3 while non-smoking zones inside venues that also permitted smoking had a mean of 56.5 µg/m3, corresponding to unhealthy air quality. Venues restricting smoking only to DSAs also had unhealthy air quality in non-smoking areas (mean PM2.5 = 87.6 µg/m3) while DSAs had hazardous levels of air quality (mean PM2.5 = 647.9 µg/m3). Smoking zones inside the venues and venues allowing smoking throughout had a mean PM2.5 of 180.3 and 182.0 µg/m3, respectively, ranking as very unhealthy. On average 3.5 persons were observed in DSAs with mean volume of 38.9 m3. Cigarette and/or hookah were the major source of PM2.5. The higher the smoker density the poorer the air quality in the venue. CONCLUSIONS: Hazardous level of PM2.5 due to tobacco products inside DSAs demonstrated the low efficiency of a smoking ban with exemptions. A complete smoking ban in food-serving venues should be in place to fully protect people from hazardous air quality conditions.

Prevalence of and factors associated with violations of a campus smoke-free policy: a cross-sectional survey of undergraduate students on a university campus in the USA.

OBJECTIVE: The aim of this study is to estimate the prevalence of smoking behaviour on campus and to identify the key factors that influence adherence to a campus smoke-free policy. DESIGN & PARTICIPANTS: This study employed a cross-sectional, self-administered survey of undergraduate students at the University of Mississippi. A random sample of all available undergraduate classes was recruited for data collection. Students were provided a survey that included questions on demographics, alcohol use, smoking status, policy awareness, policy attitudes, smoking attitudes, policy support, barriers to policy success and policy violations. RESULTS: The prevalence of past 30-day smoking was 23%. More than 63% of current smokers report ever smoking on campus, but less than 10% ever received a warning or a ticket for their violation. Nearly all respondents (92.5%) reported witnessing someone smoking on campus, and 22% reported witnessing someone receiving a ticket. Barriers to policy success include lack of reminders about the policy, lack of support from students and University administrators, and insufficient fines. Smoking behaviour (OR: 7.96; 95% CI: 5.13 to 12.36), beliefs about policy adherence (OR: 0.52; 95% CI: 0.40 to 0.69), support for the policy (OR: 0.71; 95% CI: 0.55 to 0.91) and attitudes against smoking behaviour (OR: 0.35; 95% CI: 0.25 to 0.49) were all significantly associated with self-reported policy violations. CONCLUSIONS: This study found that violations of the campus smoke-free policy were fairly frequent and the policy has been largely ineffective, indicating a need for other interventions. Approaches to improve adherence to the policy should address barriers such as reminders about the policy, better policy enforcement and support from the administration.

Stakeholder framing, communicative interaction, and policy legitimacy: anti-smoking policy in South Korea.

Since the emergence of the argumentative turn in critical policy studies, increasing attention has been paid to the crucial role played by language, context, and communicative practices in the policy process. This study aims to investigate communicative interaction between state elites and societal stakeholders in South Korea with a focus on the anti-smoking policies of two different administrations: the Roh administration (2003-2008) and the Park administration (2013-2017). As a theoretical base, this paper proposes a stakeholder-oriented approach to legitimacy, which incorporates a policy frame analysis with the concept of a three-tier policy structure (i.e., policy goals, policy tools, and tool settings). In assessing policy legitimacy, the stakeholder-oriented approach examines whether there is congruence between the three-tier policy structure and the corresponding stakeholder framing. In the Roh administration, the policy frames among the three tiers of policy structure were centered on public health promotion, whereas in the Park administration, they expanded to the domain of tax policy. The empirical findings underscore the importance of two-way communication between the government and societal stakeholders, which can be evidenced using policy frame analysis. Ultimately, the results show that policy legitimacy is more likely to be guaranteed if there is no hidden or predetermined policy intention that can be detected by stakeholder framing analysis.

Workplace smoking restrictions and support for smoking cessation in the USA: state, region, and overall trends from 2010-11 to 2014-15.

We discuss the most recent changes in smoking policies and support for smoking cessation offered to smokers at US workplaces. We used reports of employed adults (n = 112,008) regarding smoking restrictions and support for smoking cessation offered at their indoor workplaces from the 2010-11 and 2014-15 Tobacco Use Supplement-Current Population Survey. The percentage of adults who reported having workplace smoking restrictions was 94% in 2010-11 and 93% in 2014-15 (P = 0.001). There was a decrease in the Northeastern region (P < 0.001) and no significant changes in the other three US regions. The percentages decreased in Hawaii, New York, Oregon, Pennsylvania, and Tennessee and increased in Indiana, Nebraska, and Wyoming. The percentage of employees who reported having workplace support for smoking cessation increased from 24% to 29% (P < 0.001), which was uniform across all US regions but differed across the US states. The percentages decreased in Hawaii and increased in the majority of states. Analysis of smokers' reports (versus all reports) resulted in lower percentages of workplaces with smoking restrictions and support for smoking cessation. It is essential to further enhance support for smoking cessation offered to smokers at US workplaces.

A cross-sectional study of the relationship of proximal smoking environments and cessation history, plans, and self-efficacy among low-income smokers.

INTRODUCTION: Proximal environments could facilitate smoking cessation among low-income smokers by making cessation appealing to strive for and tenable. AIMS: We sought to examine how home smoking rules and proximal environmental factors such as other household members' and peers' smoking behaviors and attitudes related to low-income smokers' past quit attempts, readiness, and self-efficacy to quit. METHODS: This analysis used data from Offering Proactive Treatment Intervention (OPT-IN) (randomized control trial of proactive tobacco cessation outreach) baseline survey, which was completed by 2,406 participants in 2011/12. We tested the associations between predictors (home smoking rules and proximal environmental factors) and outcomes (past-year quit attempts, readiness to quit, and quitting self-efficacy). RESULTS: Smokers who lived in homes with more restrictive household smoking rules, and/or reported having 'important others' who would be supportive of their quitting, were more likely to report having made a quit attempt in the past year, had greater readiness to quit, and greater self-efficacy related to quitting. CONCLUSIONS: Adjustments to proximal environments, including strengthening household smoking rules, might encourage cessation even if other household members are smokers.

Smoking policies in the home have less influence on cigarettes per day and nicotine dependence level among African American than White smokers: A cross-sectional analysis.

BACKGROUND: African American smokers suffer disproportionately from tobacco-related disease caused, in part, by lower rates of smoking cessation. We examined whether smoke-free home policies and delay discounting were differentially associated with cigarettes smoked per day (CPD) and nicotine dependence (ND) among African Americans and Whites. METHODS: Secondary data analysis was conducted using data from 65 African American (n = 40) and White (n = 25) smokers who completed measures of CPD, ND, tobacco craving, stress, depression, home smoking policy, and delay discounting. RESULTS: A significant interaction was found between race and home smoking policy on CPD (B = -11.21, p = 0.002) and ND (B = -3.42, p = 0.004). Smoke-free policies in the home were associated with fewer CPD and lower ND levels among Whites, but not among African Americans. Whites who allowed smoking in their homes had significantly greater mean CPD and higher mean ND than their counterparts who did not allow smoking in the home. Among African American smokers, there were no differences in CPD and ND among those who allowed smoking in their home versus those who did not. CONCLUSIONS: The findings extend the scientific literature by suggesting that a malleable environmental factor (home smoking policy) commonly associated with cessation among Whites does not have the same influence on cessation among African American.

School Smoking Policies and Health Science Students' Use of Cigarettes, Shisha, and Dipping Tombak in Sudan.

The relationship between school smoking policies and students' tobacco use is ambiguous, and little is known about the effect of these policies in low- and middle-income countries. This study was designed to assess the effects of schools' smoking policies and the exposure to residential smoking on cigarette smoking and the use of different kinds of tobacco products by Health Science students. Self-reports of cigarette smoking, use of shisha (smoking of fruits-mixed tobacco using a bowl and a connected hose); dipping tombak (local smokeless tobacco that users usually place inside oral cavity in the groove behind the lower lip), and tobacco use on school premises are analyzed. A cross-sectional survey was carried out using a modified self-report questionnaire, originally developed by WHO, among a representative sample of 1,590 third-year HSS from 25 schools drawn from 13 universities, using a multi-stages sampling technique. The response rate was 100% for schools and 68% for students. A multilevel analysis was performed by nesting student-level in school-level variables. Results from the adjusted models revealed that, when students reported awareness of smoking restriction, they were more likely to be current smokers (OR = 2.91; 95% CI: 1.68-5.02; p = 0.021) and shisha users (OR = 2.17; 95% CI: 1.54-3.06; p = 0.021). Results from additional analysis performed among tobacco users only, showed increased risk of smokers and tombak dippers who smoked or dipped on school premises (OR = 2.38; 95% CI: 1.34-4.25; p = 0.003, OR = 2.60; 95% CI: 1.22-5.56; p = 0.013, respectively). Current smokers (OR = 3.12; 95% CI: 1.98-4.92; p = ≤ 0.001), ever smokers (OR = 1.66; 95% CI: 1.31-2.10; p = ≤ 0.001) and shisha users (OR = 1.73; 95% CI: 1.36-2.21; p = ≤ 0.001) were exposed to residential smoking on one or more days during the previous 7 days. High percentages of those who used any kind of tobacco products reported being aware of school smoking policies, indicating no clear evidence that school smoking policies had an effect on use of any of the mentioned tobacco products. The lack of compliance with school policies shows the need for further policy enforcement and sustainability, taking into account the effect of residential smoking and social influences.

Welfare analysis of a zero-smoking policy - A case study in Japan.

Smoking cessation efforts in Japan reduce smoking rates. A future zero-smoking policy would completely prohibit smoking (0% rate). We therefore analyzed the social welfare of smokers and non-smokers under a hypothetical zero-smoking policy. The demand curve for smoking from 1990 to 2014 was estimated by defining quantity as the number of cigarettes smoked and price as total tobacco sales/total cigarettes smoked by the two-stage least squares method using the tax on tobacco as the instrumental variable. In the estimation equation (calculated using the ordinary least squares method), the price of tobacco was the dependent variable and tobacco quantity the explanatory variable. The estimated constant was 31.90, the estimated coefficient of quantity was - 0.0061 (both, p < 0.0004), and the determinant coefficient was 0.9187. Thus, the 2015 consumer surplus was 1.08 trillion yen (US$ 9.82 billion) (95% confidence interval (CI), 889 billion yen (US$ 8.08 billion) - 1.27 trillion yen (US$ 11.6 billion)). Because tax revenue from tobacco in 2011 was 2.38 trillion yen (US$ 21.6 billion), the estimated deadweight loss if smoking were prohibited in 2014 was 3.31 trillion yen (US$ 30.2 billion) (95% CI, 3.13 trillion yen (US$ 28.5 billion) - 3.50 trillion yen (US$ 31.8 billion)), representing a deadweight loss about 0.6 trillion yen (US$ 5.45 billion) below the 2014 disease burden (4.10-4.12 trillion yen (US$ 37.3-37.5 billion)). We conclude that a zero-smoking policy would improve social welfare in Japan.

Exposure to workplace smoking bans and continuity of daily smoking patterns on workdays and weekends.

INTRODUCTION: Individuals may compensate for workplace smoking bans by smoking more before or after work, or escaping bans to smoke, but no studies have conducted a detailed, quantitative analysis of such compensatory behaviors using real-time data. METHODS: 124 daily smokers documented smoking occasions over 3weeks using ecological momentary assessment (EMA), and provided information on real-world exposure to smoking restrictions and type of workplace smoking policy (full, partial, or no bans). Mixed modeling and generalized estimating equations assessed effects of time of day, weekday (vs weekend), and workplace policy on mean cigarettes per hour (CPH) and reports of changing location to smoke. RESULTS: Individuals were most likely to change locations to smoke during business hours, regardless of work policy, and frequency of EMA reports of restrictions at work was associated with increased likelihood of changing locations to smoke (OR=1.11, 95% CI 1.05-1.16; p<0.0001). Workplace smoking policy, time block, and weekday/weekend interacted to predict CPH (p<0.01), such that individuals with partial work bans -but not those with full bans - smoked more at night (9pm - bed) on weekdays compared to weekends. CONCLUSIONS: There was little evidence that full bans interfered with subjects' smoking during business hours across weekdays and weekends. Smokers largely compensate for exposure to workplace smoking bans by escaping restrictions during business hours. Better understanding the effects of smoking bans on smoking behavior may help to improve their effectiveness and yield insights into determinants of smoking in more restrictive environments.
