- Abstract
Introduction: Tobacco product testing is a critical component of the Family Smoking Prevention and Tobacco Control Act (FSPTCA), which grants the Food and Drug Administration the authority to regulate tobacco products. The availability of methods and measures that can provide accurate data on the relative health risks across types of tobacco products, brands, and subbrands of tobacco products on the validity of any health claims associated with a product, and on how consumers perceive information on products toxicity or risks is crucial for making decisions on the product's potential impact on public health. These tools are also necessary for making assessments of the impact of new indications for medicinal products (other than cessation) but more importantly of tobacco products that may in the future be marketed as cessation tools.Objective: To identify research opportunities to develop empirically based and comprehensive methods and measures for testing tobacco and other nicotine-containing products so that the best science is available when decisions are made about products or policies.Methods: Literature was reviewed to address sections of the FSPTCA relevant to tobacco product evaluation; research questions were generated and then reviewed by a committee of research experts.Results: A research agenda was developed for tobacco product evaluation in the general areas of toxicity and health risks, abuse liability, consumer perception, and population effects.Conclusion: A cohesive, systematic, and comprehensive assessment of tobacco products is important and will require building consensus and addressing some crucial research questions.

- Abstract
OBJECTIVE: To evaluate the effectiveness of the Nicotrol nicotine inhaler as an aid to smoking cessation in over-the-counter (OTC) versus health-care-provider (HCP) conditions. METHODS: Five hundred twenty healthy smokers were randomized to the treatment conditions and followed for a year. RESULTS: At most follow-up visits, abstinence rates for the HCP group were 2 to 3 times those observed in the OTC group. Abstinence at 1 year was.77% in the OTC condition versus 3.08% in the HCP condition [P<.01]. Inhaler use was low. CONCLUSIONS: OTC nicotine inhaler appears to be ineffective, though quit rates are improved with HCP assistance. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: To examine previous use of nicotine replacement therapy (NRT) on the smoking-cessation efficacy of bupropion sustained release (SR). METHODS: Secondary analysis of a parallel-group, randomized, double-blind, placebo-controlled study. Smokers who had, based on self-report, no previous history of NRT (N = 453) or who had used NRT at least once (N = 440) were randomized to receive placebo, bupropion SR, nicotine transdermal system (NTS), or a combination of bupropion SR and NTS. RESULTS: Bupropion SR showed similar efficacy in participants with or without previous use of NRT. CONCLUSION: Bupropion SR is effective in promoting smoking abstinence regardless of prior NRT use.

- Abstract
Objectives: Compare the effectiveness of transdermal nicotine in an OTC (no behavioral support) vs. a physician-based minimal intervention setting (MD). Methods: Three hundred healthy adult smokers completed follow-up visits at Weeks 2, 6, 26, and 52. Subjects purchased 15 mg patches ad lib for 26 weeks. Results: No significant differences in abstinence rates between groups were found. Abstinence rates for all randomized ranged from 4.0% to 9.3%. Abstinence rates for all who purchased patches ranged from 5.3% to 12.5%. Conclusions: Use of OTC nicotine patch resulted in low cessation rates, but comparable to those when patch was combined with brief physician intervention. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To evaluate a sublingual formulation of lobeline sulfate for smoking cessation. Methods: Random assignment of 180 healthy smokers to treatment (n=90) or placebo (n=90). Treatment was self-administering a 7.5 mg lobeline sulfate sublingual or placebo tablet 9 times per day for 6 weeks. Results: No difference in cessation efficacy between placebo and active treatment. Among highly dependent smokers who completed the trial, there was a trend for higher cessation rates in the active group. Conclusion: This pilot study failed to demonstrate smoking-cessation efficacy. However, data suggest continued studies to evaluate lobeline sulfate for smoking cessation. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To assess the efficacy of transdermal nicotine as an adjunct to smoking cessation in Hispanics. Design: Randomized, double-blind, placebo-controlled pilot clinical trial. Intervention: Nicotine or placebo transdermal system (patch) and brief individual motivational support. Results: Six-week abstinence rates in the nicotine versus placebo groups were 63 versus 35%, respectively, and were 46 versus 26%, respectively, at 10 weeks. These differences in abstinence rates between the two groups were significant at 6 weeks (chi-square = 7.26, p <0.01) and 10 weeks (chi-square = 4.01, p = 0.05). Withdrawal symptoms were not suppressed, though weight was suppressed, in the transdermal nicotine group. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Varenicline helps people who smoke quit at rates 2-3 times greater than placebo. Currently in the U.S., varenicline is not available over the counter (OTC). In this study, we assessed the safety and efficacy of 1mg and 0.5mg varenicline as an OTC medication for smoking cessation in comparison to placebo., Methods: This randomized, double-blind, placebo-controlled study was performed at two clinical sites in the United States of n=313 people. The treatment period was 12 weeks. During the COVID pandemic, the protocol was modified to allow remote participation; verification of smoking status was via breath carbon monoxide levels for in-person visits and mailed urine cotinine kits for the remote participants., Results: There was no difference in biologically confirmed continuous abstinence by condition between Weeks 8-12; however, the odds of biologically confirmed point prevalence abstinence were higher for those in the 1mg b.i.d. condition than for those in the placebo condition at Week 12 (OR 3.39; 95% CI 1.49, 7.71), and were higher for those assigned to the 1.0mg b.i.d. condition than the 0.5mg b.i.d. condition at Week 12 (OR 2.37; 95% CI 1.11, 5.05). Adverse events were modest, and as expected (vivid dreams and nausea in the medication conditions)., Conclusions: The results are suggestive that varenicline is safe and effective as an OTC medication., (© The Author(s) 2024.

- Abstract
The topic of e-cigarettes is controversial. Opponents focus on e-cigarettes' risks for young people, while supporters emphasize the potential for e-cigarettes to assist smokers in quitting smoking. Most US health organizations, media coverage, and policymakers have focused primarily on risks to youths. Because of their messaging, much of the public-including most smokers-now consider e-cigarette use as dangerous as or more dangerous than smoking. By contrast, the National Academies of Science, Engineering, and Medicine concluded that e-cigarette use is likely far less hazardous than smoking. Policies intended to reduce adolescent vaping may also reduce adult smokers' use of e-cigarettes in quit attempts. Because evidence indicates that e-cigarette use can increase the odds of quitting smoking, many scientists, including this essay's authors, encourage the health community, media, and policymakers to more carefully weigh vaping's potential to reduce adult smoking-attributable mortality. We review the health risks of e-cigarette use, the likelihood that vaping increases smoking cessation, concerns about youth vaping, and the need to balance valid concerns about risks to youths with the potential benefits of increasing adult smoking cessation.

- Abstract
Objectives: Our objective was to provide data contrasting commercial tobacco retailing in Tribal versus non-Tribal jurisdictions, in 3 states. These data may be relevant for US Food and Drug Administration regulation of Tribal retailing. Methods: With Tribal permission, observations were made on commercial tobacco advertising, product variety, pricing, and retail concept for stores within and just outside Tribal jurisdictions in areas of Arizona (AZ), California (CA), and Oklahoma (OK). Results: A total of 87 Tribal (20 AZ, 53 CA, 14 OK) and 67 (10, 43, 14) non-Tribal retailer visits were completed. There was substantial variation across tribes, with sales in AZ and most CA Tribal jurisdictions handled at convenience stores, whereas OK Tribal retailing was done mostly in specialized tobacco-specialty shops. Electronic cigarettes were ubiquitous across Tribal and non-Tribal outlets. Advertising and breadth of cigarette offerings was most extensive in the tobacco specialty retailers of Tribal OK. Surprisingly, Tribally manufactured cigarettes were found only at some CA Tribal retailers. Conclusions: Some Tribal commercial tobacco outlets actually price above their non-Tribal competitors and there is substantial variation in retailing strategy across Tribal jurisdictions. Tribal governments can continue to evaluate and reform commercial tobacco retailing so as to improve Tribal health.

- Abstract
Background: Stopping the epidemic of e-cigarette use among youth has become the common goal of both regulatory authorities and health departments. JUUL is currently the most popular e-cigarette brand on the market. Young people usually obtain and exchange information about JUUL with the help of social media platforms. Along with the rising prevalence of JUUL, posts about underage JUUL buying and selling have appeared on social media platforms such as Reddit, which sharply increase the risk of minors being exposed to JUUL., Objective: This study aims to analyze Reddit messages about JUUL buying and selling among the users of the UnderageJuul subreddit, and to further summarize the characteristics of those messages. The findings and insights can contribute to a better understanding of the patterns of underage JUUL use, and help public health officials provide timely education and guidance to minors who have intentions of accessing JUUL., Methods: We used a novel cross-subreddit method to analyze the Reddit messages on 2 subreddits. From July 9, 2017, to January 7, 2018, we collected data from the UnderageJuul subreddit, which was created for underage JUUL use discussion. The data set included 716 threads, 2935 comments, and 844 Reddit users (ie, Redditors). We collected our second data set, comprising 23,840 threads and 162,106 comments posted between July 9, 2017, and January 8, 2019, from the JUUL subreddit. We conducted analyses including the following: (1) annotation of users with buying/selling intention, (2) posting patterns discovery and topic comparison, and (3) posting activeness observation of discovered Redditors. Term frequency-inverse document frequency and regular expression-enhanced keyword search methods were applied during the content analysis to extract the posting patterns. The public posting records of the discovered users on the JUUL subreddit during the year after the UnderageJuul subreddit was shut down were analyzed to determine whether they were still active and interested in obtaining JUUL., Results: Our study revealed the following: (1) Among the 716 threads on the UnderageJuul subreddit, there were 214 threads related to JUUL sale and 168 threads related to JUUL purchase, which accounted for 53.5% (382/714) of threads. (2) Among the 844 Redditors of the UnderageJuul subreddit, 23.82% (201/844) of users were annotated with buying intention, and 21.10% (178/844) of users were annotated with selling intention. There were 34 users with buying/selling intention that self-reported as being <21 years old. (3) The most common key phrases used in selling threads were "WTS," "want to sell," "for sale," and "selling" (154/214, 72.0%). The most common key phrases used in buying threads were "look for/get JUUL/pods" (58/168, 34.5%) and "WTB" (53/168, 31.5%). (4) The most important concern that UnderageJuul Redditors had in obtaining JUULs was the price (311/1306, 23.81%), followed by the delivery service (68/1306, 5.21%). (5) The most popular flavors among the users with buying/selling intention were mango, cucumber, and mint. The flavor preferences remained consistent on both subreddits. Adverse symptoms related to the mango flavor were reported by 3 users on the JUUL subreddit. (6) In total, 24.4% (49/201) of users wanted to buy JUULs and 46.6% (83/178) of users wanted to sell JUULs, including 11 self-reported underage users, who also participated in the discussions on the JUUL subreddit. (7) Within one year of the UnderageJuul subreddit shutting down, there were 40 users who continued to post 186 threads on the JUUL subreddit, including 10 threads indicating buying/selling willingness that were posted shortly after the UnderageJuul subreddit was closed., Conclusions: There were overlapping users active in the JUUL and UnderageJuul subreddits. The buying/selling-related content appeared in multiple venues with certain posting patterns from July 9, 2017, to January 7, 2018. Such content might lead to a high risk of health problems for minors, such as nicotine addiction. Based on these findings, this study provided some insights and suggestions that might contribute to the decision-making processes of regulators and public health officials., (©Hejing Liu, Qiudan Li, Yongcheng Zhan, Zhu Zhang, Daniel D Zeng, Scott J Leischow.

- Abstract
Introduction: Smoking to reduce negative affect has been identified as a key motivational feature of tobacco use. Our recent work suggests that smoking very low nicotine content (VLNC) cigarettes reduces the relationship between negative affect and smoking behavior over a 6-week period. Here, we sought to extend our findings by evaluating whether a gradual or immediate approach to switching to VLNC cigarettes led to a differential reduction in the relationship between affect and smoking behavior over a longer (20-week) period., Aims and Methods: Participants (n = 1250) were adult smokers from 10 US sites randomized to one of three groups: gradual nicotine reduction (15.5, 11.7, 5.2, 2.4, and 0.4 mg of nicotine per gram of tobacco [mg/g]), immediate nicotine reduction (0.4 mg/g), or standard nicotine content cigarettes (15.5 mg/g; control), for 20 weeks. We examined whether the relationship between affect-both negative and positive-and cigarettes per day differed as a function of reduction group., Results: We found that both negative and positive affect were associated with cigarette consumption in the control group, but not in the gradual or immediate reduction groups across the 20 weeks of exposure., Conclusions: Our results extend previous findings that switching to VLNC cigarettes disrupts the relationship between affect and cigarette consumption by showing that either gradually or immediately reducing cigarette nicotine content achieves this disruption. These findings provide further evidence that switching to VLNC cigarettes reduces nicotine-related reinforcement of cigarette smoking., Implications: These findings support the notion that switching to very low nicotine content cigarettes reduces the association between affect and smoking behavior, and that either a gradual or immediate nicotine reduction approach achieves this reduction. This provides further evidence that switching to very low nicotine content cigarettes weakens reinforcement mechanisms associated with nicotine dependence., (© The Author(s) 2019.

- Abstract
Background: On January 1, 2019, a new regulation on the control of smoking in public places was officially implemented in Hangzhou, China. On the day of the implementation, a large number of Chinese media reported the contents of the regulation on the microblog platform Weibo, causing a strong response from and heated discussion among netizens., Objective: This study aimed to conduct a content and network analysis to examine topics and patterns in the social media response to the new regulation., Methods: We analyzed all microblogs on Weibo that mentioned and explained the regulation in the first 8 days following the implementation. We conducted a content analysis on these microblogs and used social network visualization and descriptive statistics to identify key users and key microblogs., Results: Of 7924 microblogs, 12.85% (1018/7924) were in support of the smoking control regulation, 84.12% (6666/7924) were neutral, and 1.31% (104/7924) were opposed to the smoking regulation control. For the negative posts, the public had doubts about the intentions of the policy, its implementation, and the regulations on electronic cigarettes. In addition, 1.72% (136/7924) were irrelevant to the smoking regulation control. Among the 1043 users who explicitly expressed their positive or negative attitude toward the policy, a large proportion of users showed supportive attitudes (956/1043, 91.66%). A total of 5 topics and 11 subtopics were identified., Conclusions: This study used a content and network analysis to examine topics and patterns in the social media response to the new smoking regulation. We found that the number of posts with a positive attitude toward the regulation was considerably higher than that of the posts with a negative attitude toward the regulation. Our findings may assist public health policy makers to better understand the policy's intentions, scope, and potential effects on public interest and support evidence-based public health regulations in the future., (©Wanting Wen, Zhu Zhang, Ziqiang Li, Jiaqi Liang, Yongcheng Zhan, Daniel D Zeng, Scott J Leischow.

- Abstract
Background: Nicotine replacement therapy (NRT) has been demonstrated to be an effective pharmacological treatment for smoking cessation, and most types of NRT have been approved as over-the-counter (OTC) medications. In an effort to create a fast-acting, flexible, and discreet NRT, a nicotine mouth spray (NMS) has been developed. This study was designed to assess the efficacy and safety of NMS in a naturalistic setting in the United States., Methods: This was a multicenter, randomized, double-blind, placebo-controlled, parallel-group, 26-week study in 1198 smokers motivated to quit. The study was designed to resemble an OTC environment, and thus included limited intervention, limited motivational screening, and no behavioral support. The primary efficacy endpoint was carbon monoxide-verified, self-reported continuous abstinence from smoking from week 2 until week 6. The safety of NMS was assessed by measuring vital signs, visual mouth inspection, and collection of subject-reported adverse events (AEs)., Results: The percentage of subjects with carbon monoxide-verified continuous abstinence from week 2 to week 6 was statistically significantly greater in the NMS group compared with the placebo group (5.0% vs. 2.5%, p = .021). Statistically significant treatment effects for the NMS were maintained throughout the 26-week period. The study medications were generally well tolerated. The severity of AEs was similar for both treatment groups, and most AEs were of mild or moderate severity., Conclusions: These study results demonstrate that the NMS is an effective and safe smoking cessation option for smokers motivated to quit, even in a naturalistic setting and without behavioral support., Implications: This study demonstrated the safety, efficacy, and acceptability of an NMS in an OTC environment with no behavioral counseling or support. It provides an additional option for smokers motivated to quit., Trial Registration: ClinicalTrials.gov (number NCT02355665)., (© The Author(s) 2018.

- Abstract
Background: The popularity of JUUL (an e-cigarette brand) among youth has recently been reported in news media and academic papers, which has raised great public health concerns. Little research has been conducted on the age distribution, geographic distribution, approaches to buying JUUL, and flavor preferences pertaining to underage JUUL users., Objective: The aim of this study was to analyze social media data related to demographics, methods of access, product characteristics, and use patterns of underage JUUL use., Methods: We collected publicly available JUUL-related data from Reddit. We extracted and summarized the age, location, and flavor preference of subreddit UnderageJuul users. We also compared common and unique users between subreddit UnderageJuul and subreddit JUUL. The methods of purchasing JUULs were analyzed by manually examining the content of the Reddit threads., Results: A total of 716 threads and 2935 comments were collected from the subreddit UnderageJuul before it was shut down. Most threads did not mention a specific age, but ages ranged from 13 years to greater than 21 years in those that did. Mango, mint, and cucumber were the most popular among the 7 flavors listed on JUUL's official website, and 336 subreddit UnderageJuul threads mentioned 7 discreet approaches to circumvent relevant legal regulations to get JUUL products, the most common of which was purchasing JUUL from other Reddit users (n=181). Almost half of the UnderageJuul users (389/844, 46.1%) also participated in discussions on the main JUUL subreddit and sought information across multiple Reddit forums. Most (64/74, 86%) posters were from large metropolitan areas., Conclusions: The subreddit UnderageJuul functioned as a forum to explore methods of obtaining JUUL and to discuss and recommend specific flavors before it was shut down. About half of those using UnderageJuul also used the more general JUUL subreddit, so a forum still exists where youths can attempt to share information on how to obtain JUUL and other products. Exploration of such social media data in real time for rapid public health surveillance could provide early warning for significant health risks before they become major public health threats., (©Yongcheng Zhan, Zhu Zhang, Janet M Okamoto, Daniel D Zeng, Scott J Leischow.

- Abstract
Background: Cannabis concentrates, which are cannabis plant extracts that contain high concentrations of Δ-9-tetrahydrocannbinol (THC), have become increasingly popular among adults in the United States. However, no studies have reported on the prevalence or correlates of cannabis concentrate use in adolescents, who, as a group, are thought to be particularly vulnerable to the harms of THC., Methods: Participants are a racially and ethnically diverse group of 47 142 8th-, 10th-, and 12th-grade students recruited from 245 schools across Arizona in 2018. Participants reported on their lifetime and past-month marijuana and cannabis concentrate use, other substance use, and risk and protective factors for substance use problems spanning multiple life domains (ie, individual, peer, family, school, and community)., Results: Thirty-three percent of all 8th-, 10th-, and 12th-graders reported lifetime cannabis use, and 24% reported lifetime concentrate use. Seventy-two percent of all lifetime cannabis users had used concentrates. Relative to adolescent cannabis users who had not used concentrates, adolescent concentrate users were more likely to use other substances and to experience more risk factors, and fewer protective factors, for substance use problems across numerous life domains., Conclusions: Most adolescent cannabis users have used concentrates. Based on their risk and protective factor profile, adolescent concentrate users are at higher risk for substance use problems than adolescent cannabis users who do not use concentrates. Findings raise concerns about high-risk adolescents' exposure to high-THC cannabis., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

- Abstract
Objective: There is a lack of consensus on whether e-cigarettes facilitate or threaten existing tobacco prevention strategies. This uncertainty is reflected in organizations' conflicting e-cigarette position statements. We conducted a scoping review of position statements in published and gray literature to map the range and frequency of e-cigarette use recommendations. Methods: We collected 81 statements from international health organizations. Two coders independently performed qualitative content analysis to categorize e-cigarette recommendations. We explored differences based on organization type, geography, and the year recommendations were published. Results: We identified 5 recommendation types: encourage smokers to use ecigarettes as a cessation aid or as an alternative source of nicotine (N = 5); support individuals who use e-cigarettes to quit smoking (N = 20); avoid using until more research is available (N = 19); restrict access based on available evidence (N = 30); and prohibit e-cigarette marketing and sale (N = 7). Conclusion: Organizations presented diverse e-cigarette use recommendations. The variation related to organizations' differing tobacco prevention priorities and level of confidence in current e-cigarette research. These differences may create confusion. Additional research can examine whether this variability influences stakeholders' attitudes or behavior.

- Abstract
Background: The goal is to determine the delays and reduced rates of kidney transplant (KTx) for the Indigenous Americans and variables predictive of these outcomes at a large single transplant center., Methods: 300 Indigenous Americans and 300 non-Hispanic white American patients presenting for KTx evaluation from 2012-2016 were studied., Results: Compared to whites, the Indigenous Americans had the following: more diabetes, dialysis, physical limitation and worse socioeconomic characteristics(p<0.01); median difference of 20 day delay from referral to KTx evaluation, 17 day delay from approval to UNOS listing and 126.5 longer delay on the waitlist compared to whites(p<0.001). Of the Indigenous Americans listed, more died, were removed, or were still waiting than transplanted compared to whites (p<0.001). Variables predictive of delay from referral to transplant evaluation included: Indigenous race, distance from transplant center, coronary artery disease, and time on dialysis (p<0.05). Cumulative incidence of waitlisting and KTx was lower for Indigenous Americans (p<0.0001). Independent predictors of decreased likelihood of waitlisting included age, peripheral vascular disease, no caregiver, physical limitation, and illegal drug use history (p<0.05). Variables predictive of lower likelihood of KTx included Indigenous race, percentage of time inactive on the waitlist, no caregiver, and O blood type., Conclusions: Among patients referred and evaluated for KTx, the Indigenous American race was independently associated with significant delays in the KTx process after accounting for co-morbid and socioeconomic factors. Cardiovascular morbidity and physical limitation were identified as important determinants of delay and decreased likelihood of waitlisting. Further quantitative and qualitative work is needed to identify and intervene on modifiable barriers to improve access to KTx for the Indigenous Americans., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Aims: To measure carbonyl emissions from a heated tobacco product (IQOS) in comparison with an e-cigarette (Nautilus Mini) and a commercial tobacco cigarette (Marlboro Red)., Design: Regular and menthol variants of the heated tobacco product were tested. A tank-type atomizer was tested with a tobacco-flavoured liquid at 10 and 14 W. Aerosol and smoke were collected in impingers containing 2,4-dinitrophenylhydrazine. Health Canada Intense and two more intense puffing regimens were used., Setting: Analytical laboratory in Greece., Measurements: Carbonyl levels in the aerosol and smoke., Findings: At the Health Canada Intense regimen, heated tobacco products emitted 5.0-6.4 μg/stick formaldehyde, 144.1-176.7 μg/stick acetaldehyde, 10.4-10.8 μg/stick acrolein, 11.0-12.8 μg/stick propionaldehyde and 1.9-2.0 μg/stick crotonaldehyde. Compared with the tobacco cigarette, levels were on average 91.6% lower for formaldehyde, 84.9% lower for acetaldehyde, 90.6% lower for acrolein, 89.0% lower for propionaldehyde and 95.3% lower for crotonaldehyde. The e-cigarette emitted 0.5-1.0 μg/12 puffs formaldehyde, 0.8-1.5 μg/12 puffs acetaldehyde and 0.3-0.4 μg/12 puffs acrolein, but no propionaldehyde and crotonaldehyde. At more intense puffing regimens, formaldehyde was increased in heated tobacco products, but levels were three-fourfold lower compared with the tobacco cigarette. Based on the findings from Health Canada Intense puffing regimen, use of 20 heated tobacco sticks would result in approximately 85% to 95% reduced carbonyl exposure compared with smoking 20 tobacco cigarettes; the respective reduction in exposure from use of 5 g e-cigarette liquid would be 97% to > 99%., Conclusions: The IQOS heated tobacco product emits substantially lower levels of carbonyls than a commercial tobacco cigarette (Marlboro Red) but higher levels than a Nautilus Mini e-cigarette., (© 2018 Society for the Study of Addiction.)

- Abstract
Objective: As part of the Smoke-Free Illinois Act, smoking on the gambling floors of all commercial casinos in Illinois became prohibited. This study examined the effects of the Smoke-Free Illinois Act on casino admissions per-capita and real per-capita adjusted gross receipts using 18 years of data (10 years before and 8 years after the Illinois law went into effect)., Methods: We employed a difference-in-difference regression technique using monthly data for the states of Illinois, Indiana, Iowa and Missouri and control for numerous determinants expected to affect casino admissions and revenue., Results: The Smoke-free Illinois Act was found not to be a statistically significant determinant of per-capita casino admissions and of real per-capita gross adjusted receipts in all the models we estimated., Conclusions: The estimates from this study clearly indicated that the Illinois law that banned smoking in casinos has had no significant negative economic consequences for casinos in terms of per-capita admissions or revenues., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

- Abstract
Background: E-liquid is one of the main components in electronic nicotine delivery systems (ENDS). ENDS review comments could serve as an early warning on use patterns and even function to serve as an indicator of problems or adverse events pertaining to the use of specific e-liquids-much like types of responses tracked by the Food and Drug Administration (FDA) regarding medications., Objective: This study aimed to understand users' "vaping" experience using sentiment opinion summarization techniques, which can help characterize how consumers think about specific e-liquids and their characteristics (eg, flavor, throat hit, and vapor production)., Methods: We collected e-liquid reviews on JuiceDB from June 27, 2013 to December 31, 2017 using its public application programming interface. The dataset contains 27,070 reviews for 8058 e-liquid products. Each review is accompanied by an overall rating and a set of 4 aspect ratings of an e-liquid, each on a scale of 1-5: flavor accuracy, throat hit, value, and cloud production. An iterative dichotomiser 3 (ID3)-based influential aspect analysis model was adopted to learn the key elements that impact e-liquid use. Then, fine-grained sentiment analysis was employed to mine opinions on various aspects of vaping experience related to e-liquids., Results: We found that flavor accuracy and value were the two most important aspects that affected users' sentiments toward e-liquids. Of reviews in JuiceDB, 67.83% (18,362/27,070) were positive, while 12.67% (3430/27,070) were negative. This indicates that users generally hold positive attitudes toward e-liquids. Among the 9 flavors, fruity and sweet were the two most popular. Great and sweet tastes, reasonable value, and strong throat hit made users satisfied with fruity and sweet flavors, whereas "strange" tastes made users dislike those flavors. Meanwhile, users complained about some e-liquids' steep or expensive prices, bad quality, and harsh throat hit. There were 2342 fruity e-liquids and 2049 sweet e-liquids. There were 55.81% (1307/2342) and 59.83% (1226/2049) positive sentiments and 13.62% (319/2342) and 12.88% (264/2049) negative sentiments toward fruity e-liquids and sweet e-liquids, respectively. Great flavors and good vapors contributed to positive reviews of fruity and sweet products. However, bad tastes such as "sour" or "bitter" resulted in negative reviews. These findings can help businesses and policy makers to further improve product quality and formulate effective policy., Conclusions: This study provides an effective mechanism for analyzing users' ENDS vaping experience based on sentiment opinion summarization techniques. Sentiment opinions on aspect and products can be found using our method, which is of great importance to monitor e-liquid products and improve work efficiency., (©Qiudan Li, Can Wang, Ruoran Liu, Lei Wang, Daniel Dajun Zeng, Scott James Leischow.

- Abstract
Background: The World Conference on Tobacco or Health (WCTOH) is held every three years to foster communication and collaboration on global tobacco control. Very little is known about the nature of interactions between WCTOH attendees and their linkages to tobacco control organizations, so knowing this information could help improve tobacco control efforts., Methods: At the 2015 WCTOH, we implemented an online survey to assess barriers to global tobacco control activities, which information sources they use for tobacco control information, and with whom they interact regarding tobacco control., Results: A total of 169 respondents completed the survey, with responses from all six World Health Organization (WHO) regions. Respondents worked in all areas of tobacco control; the most common were research (29.2%) and patient care/treatment (23.3%). The top barriers faced regarding tobacco control activities were: funding is weak (56.8%), government commitment (45.0%), tobacco industry interference (43.8%), and lack of coordination (34.3%). The network analysis identified Framework Convention Alliance (FCA) and Society for Research on Nicotine and Tobacco (SRNT) as the two most prominent groups that people belonged to and where they went to exchange information and best practices. Important regional and country specific groups also appear to be growing, such as the African Tobacco Control Alliance (ATCA) and the Argentinian Association of Tabacology (ASAT)., Discussion: Mapping and better understanding the global tobacco control network is important for informing knowledge exchange and best practices, particularly as increasing attention is being focused on global tobacco control efforts in low- and middle-income countries in particular., Conclusions: The present study demonstrates that even a subsample of the WCTOH shows considerable collaboration. The full WCTOH network should be mapped in order to foster greater collaboration that has the the potential to improve global tobacco control efforts.

- Abstract
Background: Electronic cigarette (e-cigarette) is an emerging product with a rapid-growth market in recent years. Social media has become an important platform for information seeking and sharing. We aim to mine hidden topics from e-cigarette datasets collected from different social media platforms., Objective: This paper aims to gain a systematic understanding of the characteristics of various types of social media, which will provide deep insights into how consumers and policy makers effectively use social media to track e-cigarette-related content and adjust their decisions and policies., Methods: We collected data from Reddit (27,638 e-cigarette flavor-related posts from January 1, 2011, to June 30, 2015), JuiceDB (14,433 e-juice reviews from June 26, 2013 to November 12, 2015), and Twitter (13,356 "e-cig ban"-related tweets from January, 1, 2010 to June 30, 2015). Latent Dirichlet Allocation, a generative model for topic modeling, was used to analyze the topics from these data., Results: We found four types of topics across the platforms: (1) promotions, (2) flavor discussions, (3) experience sharing, and (4) regulation debates. Promotions included sales from vendors to users, as well as trades among users. A total of 10.72% (2,962/27,638) of the posts from Reddit were related to trading. Promotion links were found between social media platforms. Most of the links (87.30%) in JuiceDB were related to Reddit posts. JuiceDB and Reddit identified consistent flavor categories. E-cigarette vaping methods and features such as steeping, throat hit, and vapor production were broadly discussed both on Reddit and on JuiceDB. Reddit provided space for policy discussions and majority of the posts (60.7%) holding a negative attitude toward regulations, whereas Twitter was used to launch campaigns using certain hashtags. Our findings are based on data across different platforms. The topic distribution between Reddit and JuiceDB was significantly different (P<.001), which indicated that the user discussions focused on different perspectives across the platforms., Conclusions: This study examined Reddit, JuiceDB, and Twitter as social media data sources for e-cigarette research. These mined findings could be further used by other researchers and policy makers. By utilizing the automatic topic-modeling method, the proposed unified feedback model could be a useful tool for policy makers to comprehensively consider how to collect valuable feedback from social media., Competing Interests: Scott J Leischow has served as a paid consultant to or conducted research for Pfizer, GSK, Cypress BioScience, and McNeil Consumer. McNeil Consumer is collaborating with GSK on a current study on nicotine replacement, which is being conducted by Scott J Leischow, and GSK markets bupropion., (©Yongcheng Zhan, Ruoran Liu, Qiudan Li, Scott James Leischow, Daniel Dajun Zeng.

- Abstract
The 60% decline in the prevalence of cigarette smoking among U.S. adults over the past 50 years represents a significant public health achievement. This decline was steered in part by national, state, and local tobacco control programs and policies, such as public education campaigns; widespread smoke-free air laws; higher cigarette prices that have been driven by large increases in federal, state, and local cigarette excise taxes; and other tobacco control policy and systems-level changes that discourage smoking. Using the MPOWER framework informed by the Centers for Disease Control and Prevention (CDC) Office on Smoking and Health and the World Health Organization (WHO), this paper reviews these accomplishments and identifies gaps in tobacco control policy implementation and additional research needed to extend these historic successes., Competing Interests: Conflict of Interest None declared.

- Abstract
The research reported here is an analysis of the evolution of the relationships that comprise a single public health network, focusing especially on the position of the network administrative organization (Provan and Kenis, 2008) in the flow of knowledge among a large number of organizations providing similar services. Our study examines the North American Quitline Consortium (NAQC), a multi-sector network that spans the US and Canada and whose members provide telephone-based tobacco cessation services to anyone interested in quitting smoking. Data were collected using web-based surveys at three different points of time. Implications are discussed for network organizing, for both theory and practice, focusing especially on the importance of the network administrative organization in shaping the evolution of the whole network information flow.

- Abstract
Background: Comprehensive smoke-free laws are effective at protecting non-smokers and reducing tobacco use, yet they are not widely adopted by tribal governments., Methods: A series of smoke-free policy initiatives on the Navajo Nation, beginning in 2008, were reviewed to identify key issues, successes and setbacks., Results: It has been essential that proposed policies acknowledge the Navajo people's spiritual use of nát'oh, a sacred plant used for gift-giving, medicinal purposes and traditional ceremonies, while simultaneously discouraging a secular use of commercial tobacco. Concern that smoke-free policies economically harm tribal casinos has been a major barrier to broad implementation of comprehensive smoke-free laws in Navajo Nation., Conclusions: It is necessary for tobacco control researchers and advocates to build relationships with tribal leaders and casino management in order to develop the business case that will take comprehensive smoke-free policies to scale throughout tribal lands., (Published by the BMJ Publishing Group Limited.

Introduction: Indigenous worldviews and research approaches are fundamental to make meaning of complex health issues and increase the likelihood of identifying existing cultural protective factors that have contributed to the resilience and survival of Indigenous people worldwide., Objective: We describe the process for applying the Diné (Navajo) paradigm of Są'áh Naagháí Bik'eh Hózhóó (SNBH), a belief system that guides harmonious living, and demonstrate how the application of SNBH enhances understanding of Navajo principles for well-being. Specifically, we juxtapose this analysis with a conventional qualitative analysis to illuminate and interpret Diné perspectives on the health and economic impact of commercial secondhand smoke and smoke-free policy., Methods: Focus groups were conducted throughout Navajo Nation to assess the appeal and impact of several evidence-based messages regarding the health and economic impact of smoke-free policy., Results: Diné perspectives have shifted away from family and cultural teachings considered protective of a smoke-free life, and struggle to balance the ethical and economics of respect for individual and collective rights to live and work in smoke-free environments., Conclusions: Indigenous-centred approaches to public health research and policy analysis contribute to understanding the cultural knowledge, practices and beliefs that are protective of the health and well-being of Indigenous people., (Published by the BMJ Publishing Group Limited.

- Abstract
Background: Dabbing is an emerging method of marijuana ingestion. However, little is known about dabbing owing to limited surveillance data on dabbing., Objective: The aim of the study was to analyze Google search data to assess the scope and breadth of information seeking on dabbing., Methods: Google Trends data about dabbing and related topics (eg, electronic nicotine delivery system [ENDS], also known as e-cigarettes) in the United States between January 2004 and December 2015 were collected by using relevant search terms such as "dab rig." The correlation between dabbing (including topics: dab and hash oil) and ENDS (including topics: vaping and e-cigarette) searches, the regional distribution of dabbing searches, and the impact of cannabis legalization policies on geographical location in 2015 were analyzed., Results: Searches regarding dabbing increased in the United States over time, with 1,526,280 estimated searches during 2015. Searches for dab and vaping have very similar temporal patterns, where the Pearson correlation coefficient (PCC) is .992 (P<.001). Similar phenomena were also obtained in searches for hash oil and e-cigarette, in which the corresponding PCC is .931 (P<.001). Dabbing information was searched more in some western states than other regions. The average dabbing searches were significantly higher in the states with medical and recreational marijuana legalization than in the states with only medical marijuana legalization (P=.02) or the states without medical and recreational marijuana legalization (P=.01)., Conclusions: Public interest in dabbing is increasing in the United States. There are close associations between dabbing and ENDS searches. The findings suggest greater popularity of dabs in the states that legalized medical and recreational marijuana use. This study proposes a novel and timely way of cannabis surveillance, and these findings can help enhance the understanding of the popularity of dabbing and provide insights for future research and informed policy making on dabbing., Competing Interests: Conflicts of Interest: None declared.

- Abstract
Background: The electronic cigarette (e-cigarette) market has grown rapidly in recent years. However, causes of e-cigarette related symptoms among users and their impact on health remain uncertain. This research aims to mine the potential relationships between symptoms and e-liquid components, such as propylene glycol (PG), vegetable glycerine (VG), flavor extracts, and nicotine, using user-generated data collected from Reddit., Methods: A total of 3605 e-liquid related posts from January 1st, 2011 to June 30th, 2015 were collected from Reddit. Then the patterns of VG/PG distribution among different flavors were analyzed. Next, the relationship between throat hit, which was a typical symptom of e-cigarette use, and e-liquid components was studied. Finally, other symptoms were examined based on e-liquid components and user sentiment., Results: We discovered 3 main sets of findings: 1) We identified three groups of flavors in terms of VG/PG ratios. Fruits, cream, and nuts flavors were similar. Sweet, menthol, and seasonings flavors were classified into one group. Tobacco and beverages flavors were the third group. 2) Throat hit was analyzed and we found that menthol and tobacco flavors, as well as high ratios of PG and nicotine level, could produce more throat hit. 3) A total of 9 systems of 25 symptoms were identified and analyzed. Components including VG/PG ratio, flavor, and nicotine could be possible reasons for these symptoms., Conclusions: E-liquid components shown to be associated with e-cigarette use symptomology were VG/PG ratios, flavors, and nicotine levels. Future analysis could be conducted based on the structure of e-liquid components categories built in this study. Information revealed in this study could be utilized by e-cigarette users to understand the relationship between e-liquid type and symptoms experienced, by vendors to choose appropriate recipes of e-liquid, and by policy makers to develop new regulations.

- Abstract
Introduction: While many medications can be effective aids to quitting tobacco, real world adherence to smoking cessation medications may render a potentially effective medication ineffective. The present study investigated the role of adherence on treatment outcomes in a bupropion dose-response study among adolescent smokers trying to quit smoking., Methods: Three hundred twelve adolescent boys (n = 143) and girls (n = 169) between the ages of 14-17 were enrolled in the study, and were randomly assigned to use either 300 mg, 150 mg or placebo bupropion to quit smoking. Among the eligibility criterion, participants had to smoke at least six cigarettes per day, be motivated to quit smoking (self report), have an exhaled carbon monoxide level greater than or equal to 10 ppm, and report at least two previous quit attempts. Adherence to medication was determined by both self-report and actual counts of unused medication and empty medication packaging. Smoking status was determined by a combination of self-report and biochemical verification (breath carbon monoxide and urine cotinine)., Results: Cotinine-confirmed quit rates were significantly higher as a function of high adherence (20.69%) relative to low adherence (0.00%) in the 300-mg Bupropion Sustained Release group. Overall adherence in all study conditions in this highly controlled study was high (74%), but was significantly lower in non-white participants., Conclusions: Effectiveness of bupropion for adolescent smoking cessation is contingent on achieving high rates of medication adherence, but considerable variations in adherence impacted outcomes., Implications: Few studies have assessed the safety and efficacy of medications to help adolescent smokers quit, and we conducted one such study assessing bupropion. In this analysis of that original study, we assess the role of adherence in use of medication and quit rates. We found that adherence was related to outcomes, particularly in the 300-mg dose of bupropion., (© The Author 2015.

- Abstract
There is strong evidence that cigarette smoking causes adverse outcomes in people with cancer. However, more research is needed regarding those effects and the effects of alternative tobacco products and of secondhand smoke, the effects of cessation (before diagnosis, during treatment, or during survivorship), the biologic mechanisms, and optimal strategies for tobacco dependence treatment in oncology. Fundamentally, tobacco is an important source of variation in clinical treatment trials. Nevertheless, tobacco use assessment has not been uniform in clinical trials. Progress has been impeded by a lack of consensus regarding tobacco use assessment suitable for cancer patients. The NCI-AACR Cancer Patient Tobacco Use Assessment Task Force identified priority research areas and developed recommendations for assessment items and timing of assessment in cancer research. A cognitive interview study was conducted with 30 cancer patients at the NIH Clinical Center to evaluate and improve the measurement items. The resulting Cancer Patient Tobacco Use Questionnaire (C-TUQ) includes "Core" items for minimal assessment of tobacco use at initial and follow-up time points, and an "Extension" set. Domains include the following: cigarette and other tobacco use status, intensity, and past use; use relative to cancer diagnosis and treatment; cessation approaches and history; and secondhand smoke exposure. The Task Force recommends that assessment occur at study entry and, at a minimum, at the end of protocol therapy in clinical trials. Broad adoption of the recommended measures and timing protocol, and pursuit of the recommended research priorities, will help us to achieve a clearer understanding of the significance of tobacco use and cessation for cancer patients., (©2016 American Association for Cancer Research.)

- Abstract
Objective: Adolescent overweight and obesity and smoking continue to be very important health challenges because of their lasting effects on overall health. Weight gain after smoking cessation is a barrier to quitting as well as a negative consequence to health. This study reports changes in the body mass index (BMI) z-scores of adolescent smokers participating in a dose-ranging clinical trial of bupropion SR (150 mg/day and 300 mg/day) for smoking cessation., Methods: A total of N = 296 adolescent smokers (placebo n = 100, 150 mg/day n = 101, 300 mg/day n = 95) with a BMI z-score of 0.5 (sd: 1.4), 0.5 (sd: 1.3), and 0.5 (sd: 1.2) in the placebo, 150 mg/day, and 300 mg/day groups, respectively, were followed for 6 months., Results: Adolescents in the 300 mg/day group had a significant reduction in BMI z-score 6 weeks after quitting (β = -0.16, CI = (-0.29, -0.04), P-value = 0.01). This result was not sustained at the 6-month follow-up., Conclusions: A reduction in BMI z-score during smoking cessation with bupropion has important implications for the future of adolescent smoking cessation. These results are particularly relevant for adolescents who have either overweight or obesity or who have reservations about quitting for fear of gaining weight or BMI., (© 2015 The Obesity Society.)

- Abstract
In recent years, the emerging electronic cigarette (e-cigarette) marketplace has shown great development prospects all over the world. Reddit, one of the most popular forums in the world, has a very large user group and thus great influence. This study aims to gain a systematic understanding of e-cigarette flavors based on data collected from Reddit. Flavor popularity, mixing, characteristics, trends, and brands are analyzed. Fruit flavors were mentioned the most (n = 15,720) among all the posts and were among the most popular flavors (n = 2902) used in mixed blends. Strawberry and vanilla flavors were the most popular for e-juice mixing. The number of posts discussing e-cigarette flavors has increased sharply since 2014. Mt. Baker Vapor and Hangen were the most popular brands discussed among users. Information posted on Reddit about e-cigarette flavors reflected consumers' interest in a variety of flavors. Our findings suggest that Reddit could be used for data mining and analysis of e-cigarette-related content. Understanding how e-cigarette consumers' view and utilize flavors within their vaping experience and how producers and marketers use social media to promote flavors and sell products could provide valuable information for regulatory decision-makers.

- Abstract
Objectives: We explored whether various key stakeholders considered cost sharing with state telephone-based tobacco cessation quitlines, because including tobacco cessation services as part of the required essential health benefits is a new requirement of the Patient Protection and Affordable Care Act (ACA)., Methods: We analyzed qualitative data collected from interviews conducted in April and May of 2014 with representatives of state health departments, quitline service providers, health plans, and insurance brokers in 4 US states., Results: State health departments varied in the strategies they considered the role their state quitline would play in meeting the ACA requirements. Health plans and insurance brokers referred to state quitlines because they were perceived as effective and free, but in 3 of the 4 states, the private stakeholder groups did not consider cost sharing., Conclusions: If state health departments are going to initiate cost-sharing agreements with private insurance providers, then they will need to engage a broad array of stakeholders and will need to overcome the perception that state quitline services are free.

- Abstract
Introduction: Research has documented growing availability and use of e-cigarettes in the United States over the last decade., Methods: We conducted a national panel survey of current adult cigarette smokers to assess attitudes, beliefs, and behaviors relating to e-cigarette use in the United States (N = 2,254)., Results: Among current cigarette smokers, 20.4% reported current use of e-cigarettes on some days and 3.7% reported daily use. Reported reasons for e-cigarette use included: quit smoking (58.4%), reduce smoking (57.9%), and reduce health risks (51.9%). No significant differences in sociodemographic characteristics between e-cigarette users and nonusers were observed. Prior quit attempts were reported more frequently among e-cigarette users (82.8%) than nonusers (74.0%). Intention to quit was reported more frequently among e-cigarette users (64.7%) than nonusers (46.8%). Smokers intending to quit were more likely to be e-cigarette users than those not intending to quit (odds ratio [OR] = 1.90, CI =1.36-2.65). Those who used e-cigarettes to try to quit smoking (OR = 2.25, CI = 1.25-4.05), reduce stress (OR = 3.66, CI = 1.11-12.09), or because they cost less (OR = 3.42, CI = 1.64-7.13) were more likely to report decreases in cigarette smoking than those who did not indicate these reasons. Smokers who reported using e-cigarettes to quit smoking (OR = 16.25, CI = 8.32-31.74) or reduce stress (OR = 4.30, CI = 1.32-14.09) were significantly more likely to report an intention to quit than those who did not indicate those reasons for using e-cigarettes., Conclusions: Nearly a quarter of smokers in our study reported e-cigarettes use, primarily motivated by intentions to quit or reduce smoking. These findings identify a clinical and public health opportunity to re-engage smokers in cessation efforts., (© The Author 2015.

- Abstract
Background: Health systems play key roles in identifying tobacco users and providing evidence-based care to help them quit. This treatment includes different methods such as simple medical consultation, medication, and telephone counseling. To assess different quit smoking methods selected by patients in tobacco cessation centers in Iran in order to identify those that are most appropriate for the country health system., Methods: In this cross-sectional and descriptive study, a random sample of all quit centers at the country level was used to obtain a representative sample. Patients completed the self-administered questionnaire which contained 10 questions regarding the quality, cost, effect, side effects and the results of quitting methods using a 5-point Likert-type scale. Percentages, frequencies, mean, T-test, and variance analyses were computed for all study variables., Results: A total of 1063 smokers returned completed survey questionnaires. The most frequently used methods were Nicotine Replacement Therapy (NRT) and combination therapy (NRT and Counseling) with 228 and 163 individuals reporting these respectively. The least used methods were hypnotism (n = 8) and the quit and win (n = 17). The methods which gained the maximum scores were respectively the combined method, personal and Champix with means of 21.4, 20.4 and 18.4. The minimum scores were for e-cigarettes, hypnotism and education with means of 12.8, 11 and 10.8, respectively. There were significant differences in mean scores based on different cities and different methods., Conclusions: According to smokers' selection the combined therapy, personal methods and Champix are the most effective methods for quit smoking and these methods could be much more considered in the country health system.

- Abstract
Objectives: We examined the coevolution of information sharing and implementation of evidence-based practices among US and Canadian tobacco cessation quitlines within the North American Quitline Consortium (NAQC)., Methods: Web-based surveys were used to collect data from key respondents representing each of 74 participating funders of NAQC quitlines during the summer and fall of 2009, 2010, and 2011. We used stochastic actor-based models to estimate changes in information sharing and practice implementation in the NAQC network., Results: Funders were more likely to share information within their own country and with funders that contracted with the same service provider. Funders contracting with larger service providers shared less information but implemented significantly more practices. Funders connected to larger numbers of tobacco control researchers more often received information from other funders. Intensity of ties to the NAQC network administrative organization did not influence funders' decisions to share information or implement practices., Conclusions: Our findings show the importance of monitoring the NAQC network over time. We recommend increased cross-border information sharing and sharing of information between funders contracting with different and smaller service providers.

This treatment includes different methods such as simple medical consultation, medication, and telephone counseling. To assess physicians' opinions towards quality and result of different quit smoking methods provided in tobacco cessation services centers in Iran., Methods: In this cross-sectional and descriptive study, random sampling of all quit centers at country level was used to obtain a representative sample size of 100 physicians. Physicians completed a self-administered questionnaire which contained 10 questions regarding the quality, cost, effect, side effects, and the results of quitting methods using a 5-point Likert-type scale. Percentages, frequencies, mean, T-test, and variance analyses were computed for all study variables., Results: Most experts preferred to use combination quit smoking methods and then Nicotine Replacement Therapy (NRT) with 26 and 23, respectively. The least used methods were quit line and some methods without medication with 3 cases. The method which gained the maximum scores were telephone consultation, acupuncture, Willpower, Champix, combined method, and Interactive Voice Response (IVR) with the mean of 23.3, 23, 22.5, 22, 21.7 and 21.3, respectively. The minimum scores were related to e-cigarette, some methods without medication, and non-NRT medication with the mean of 12.3, 15.8 and 16.2, respectively. There were no significant differences in the mean of scores based on different cities (P = 0.256). Analysis of variance in mean scores showed significant differences in the means scores of different methods (P < 0.000)., Conclusions: According to physicians acupuncture, personal methods and Champix are the most effective methods and these methods could be much more feasible and cost effective than other methods.

- Abstract
Social media is becoming a new battlefield for tobacco "wars". Evaluating the current situation is very crucial for the advocacy of tobacco control in the age of social media. To reveal the impact of tobacco-related user-generated content, this paper characterizes user interaction and social influence utilizing social network analysis and information theoretic approaches. Our empirical studies demonstrate that the exploding pro-tobacco content has long-lasting effects with more active users and broader influence, and reveal the shortage of social media resources in global tobacco control. It is found that the user interaction in the pro-tobacco group is more active, and user-generated content for tobacco promotion is more successful in obtaining user attention. Furthermore, we construct three tobacco-related social networks and investigate the topological patterns of these tobacco-related social networks. We find that the size of the pro-tobacco network overwhelms the others, which suggests a huge number of users are exposed to the pro-tobacco content. These results indicate that the gap between tobacco promotion and tobacco control is widening and tobacco control may be losing ground to tobacco promotion in social media.

- Abstract
This paper conducted one of the first comprehensive international Internet analyses of seasonal patterns in information seeking concerning tobacco and lung cancer. Search query data for the terms "tobacco" and "lung cancer" from January 2004 to January 2014 was collected from Google Trends. The relevant countries included the USA, Canada, the UK, Australia, and China. Two statistical approaches including periodogram and cross-correlation were applied to analyze seasonal patterns in the collected search trends and their associations. For these countries except China, four out of six cross-correlations of seasonal components of the search trends regarding tobacco were above 0.600. For these English-speaking countries, similar patterns existed in the data concerning lung cancer, and all cross-correlations between seasonal components of the search trends regarding tobacco and that regarding lung cancer were also above 0.700. Seasonal patterns widely exist in information seeking concerning tobacco and lung cancer on an international scale. The findings provide a piece of novel Internet-based evidence for the seasonality and health effects of tobacco use.

- Abstract
Background: The commercial potential of social media is utilized by tobacco manufacturers and vendors for tobacco promotion online. However, the prevalence and promotional strategies of pro-tobacco content in social media are still not widely understood., Objective: The goal of this study was to reveal what is presented by the tobacco industry, and how it promotes itself, on social media sites., Methods: The top 70 popular cigarette brands are divided into two groups according to their retail prices: group H (brands with high retail prices) and group L (brands with low retail prices). Three comprehensive searches were conducted on Facebook, Wikipedia, and YouTube respectively using the top 70 popular cigarette brands as keywords. We identified tobacco-related content including history and culture, product features, health warnings, home page of cigarette brands, and Web-based tobacco shops. Furthermore, we examined the promotional strategies utilized in social media., Results: According to the data collected from March 3, 2014 to March 10, 2014, 43 of the 70 representative cigarette brands had created 238 Facebook fan pages, 46 cigarette brands were identified in Wikipedia, and there were over 120,000 pro-tobacco videos on YouTube, associated with 61 cigarette brands. The main content presented on the three social media websites differs significantly. Wikipedia focuses on history and culture (67%, 32/48; P<.001). Facebook mainly covers history and culture (37%, 16/43; P<.001) and major products (35%, 15/43), while YouTube focuses on the features of major tobacco products (79%, 48/61; P=.04) and information about Web-based shops (49%, 30/61; P=.004). Concerning the content presented by groups H and L, there is no significant difference between the two groups. With regard to the promotional strategies used, sales promotions exist extensively in social media. Sales promotion is more prevalent on YouTube than on the other two sites (64%, 39/61 vs 35%, 15/43; P=.004). Generally, the sale promotions of higher-cost brands in social media are more prevalent than those of lower-cost brands (55%, 16/29 vs 7%, 1/14; P<.001 for Facebook; 78%, 28/36 vs 44%, 11/25; P=.005 for YouTube)., Conclusions: The prevalence of cigarette brands in social media allows more pro-tobacco information to be accessed by online users. This dilemma indicates that corresponding regulations should be established to prevent tobacco promotion in social media.

- Abstract
Objectives: We examined relationships between implementation of tobacco quitline practices, levels of evidence of practices, and quitline reach and spending., Methods: In June and July 2009, a total of 176 quitline funders and providers in the United States and Canada completed a survey on quitline practices, in particular quitline-level implementation for the reported practices. From these data, we selected and categorized evidence-based and emerging quitline practices by the strength of the evidence for each practice to increase quitline efficacy and reach., Results: The proportion of quitlines implementing each practice ranged from 3% (text messaging) to 92% (providing a multiple-call protocol). Implementation of practices showing higher levels of evidence for increasing either reach or efficacy showed moderate but significant positive correlations with both reach outcomes and spending levels. The strongest correlation was between reach outcomes and spending levels (r=0.80; P<.01)., Conclusions: The strong relationship between quitline spending and reach reinforces the need to increase quitline funding to levels commensurate with national cessation goals.

- Abstract
Background: During recent years, there have been many advances in different types of pharmacological and non-pharmacological tobacco control treatments. In this study, we aimed to identify the most effective smoking cessation methods used in quit based upon a review of the literature., Methods: We did a search of PubMed, limited to English publications from 2000 to 2012. Two trained reviewers independently assessed titles, abstracts and full texts of articles after a pilot inter-rater reliability assessment which was conducted by the author (GH). The total number of papers and their conclusions including recommendation of that method (positive) or not supporting (negative) was computed for each method. The number of negative papers was subtracted from the number of positive ones for each method. In cases of inconsistency between the two reviewers, these were adjudicated by author., Results: Of the 932 articles that were critically assessed, 780 studies supported quit smoking methods. In 90 studies, the methods were not supported or rejected and in 62 cases the methods were not supported. Nicotine replacement therapy (NRT), Champix and Zyban with 352, 117 and 71 studies respectively were the most supported methods and e-cigarettes and non-Nicotine medications with one case were the least supported methods. Finally, NRT with 39 and Champix and education with 36 scores were the most supported methods., Conclusions: Results of this review indicate that the scientific papers in the most recent decade recommend the use of NRT and Champix in combination with educational interventions. Additional research is needed to compare qualitative and quantitative studies for smoking cessation.
