RESUMO
BACKGROUND: Gutkha or Paan masala with tobacco is commonly used smokeless tobacco product in India. Given the restrictions on advertisement and promotion of Gutkha and the necessity of warning labels on tobacco products, the tobacco industry has popularised paan masala without tobacco as a surrogate product. Paan masala itself is harmful for health but remains beyond scope of current tobacco control policies. It was important to understand prevalence and determinants of its use (with or without tobacco). METHODS: Data from the Global Adult Tobacco Survey (GATS)-2, India was used to estimate prevalence of paan masala use (with or without tobacco) in India. Multi-nominal regression and logistic regression were used to calculate risk ratios and odds ratios. RESULTS: The prevalence of any form of paan masala was 12.1% among adults in India. Prevalence was higher among males (17.8%) than females (6.0%), aged 25-44 years (14.5%) than those aged 65 years or above (9.0%). Relative risk ratio (RRR) for Paan masala with tobacco was significantly high among those with no formal schooling (RRR:2.00) and among those in poorest wealth quintiles (RRR:1.26). While, RRR were lower for Paan masala use without tobacco among those with no formal schooling (RRR:0.95) and among poorest wealth quintiles (RRR:0.78). Region-wise AOR were highest for North-East (AOR:4.80) and Central regions (AOR:4.76) compared to South India. CONCLUSION: The prevalence of paan masala use is high in India. Persons belonging to lower socioeconomic status or having no formal schooling have higher risk of consuming paan masala with tobacco. However, persons from higher wealth quintiles or having formal schooling had higher risk of use of paan masala without tobacco. These findings need careful attention of policy makers and law enforcers as it indicates different marketing strategies might have adopted by industry to target these two mutually exclusive population groups.

INTRODUCTION: Cigarette smoking is strongly associated with the development of cardiovascular disease (CVD). However, evidence is limited as to whether smokeless tobacco (ST) use is associated with CVD. AIMS AND METHODS: Using data from 4347 adults in the Population Assessment of Tobacco and Health Study (2013-2014), we compared geometric mean concentrations of CVD-related harm biomarkers and biomarkers of exposure among exclusive ST users and exclusive cigarette smokers-in relation to recent nicotine exposure-and never tobacco users, adjusting for age, sex, race/ethnicity, income, body mass index, and CVD. Biomarker levels among exclusive ST users who were former established cigarette smokers were compared with exclusive cigarette smokers. RESULTS: Compared with cigarette smokers, ST users had significantly higher concentrations of total nicotine equivalents (TNE) but lower concentrations of inflammatory (high-sensitivity C-reactive protein, interleukin-6, intercellular adhesion molecule, fibrinogen) and oxidative stress (8-isoprostane) biomarkers (all p < .05). Biomarker levels among ST users were similar to never smokers. ST users who were former cigarette smokers had lower levels of inflammatory and oxidative stress biomarkers and biomarkers of exposure (cadmium, lead, 1-hydroxypyrene, acrylonitrile, and acrolein), compared with cigarettes smokers (p < .05), despite having higher TNE levels (p < .05). Among cigarette smokers, but not among ST users, inflammatory biomarkers and TNE were highly correlated. CONCLUSIONS: ST use is not associated with increases in biomarkers of CVD-related harm and exposure, compared with never smokers, despite exposure to nicotine at levels higher than those observed among cigarette smokers. These findings support the concept that increases in CVD risk among cigarette smokers is caused primarily by constituents of tobacco smoke other than nicotine. IMPLICATIONS: Despite having higher levels of nicotine and compared with exclusive cigarette smokers, exclusive ST users (including those who were former cigarette smokers) had significantly lower concentrations of inflammatory and oxidative stress biomarkers, comparable to levels observed among never tobacco users. These findings suggest that increases in CVD risk among cigarette smokers is caused primarily by tobacco constituents other than nicotine and that switching to ST is likely associated with lower CVD risk.

INTRODUCTION: neffa, a form of air-dried smokeless tobacco used in North Africa, is spuriously perceived as a lower risk alternative to smoking. The objective of this study was to provide information on some harmful constituents of neffa and to use them for cancer risk assessment. METHODS: a high-performance liquid chromatography method coupled with fluorescence detector was used to determine polycyclic aromatic hydrocarbons (PAHs) in one sample of neffa. An atomic absorption spectrometry was performed to determine the concentrations of lead and cadmium in three samples of neffa. The levels of toxicants found in neffa were used to assess for lifetime cancer risk as advocated by the US Environment Protection Agency. RESULTS: the determination of PAHs in neffa allowed the identification of phenanthrene and anthracene. However, the higher molecular weight PAHs such as Benzo(a)Pyrene B(a)P were not detected. The concentrations of cadmium and lead varied between 1.3 to 2.8µg/g and 1.7 to 4.6µg/g respectively. Cancer risk for cadmium and lead varied between 4.2E-03 to 9.3E-03 and 2.5E-06 to 6.4E-06 respectively. Cancer risk for Cd exceeded the range of 10E-04 to 10E-06 of an acceptable risk. CONCLUSION: neffa is not a healthy alternative for overcoming smoking addiction. It contains mineral and organic pulmonary toxicants. This study could serve as a scientific basis to inform consumers about the products´ toxicity and help them to quit smokeless tobacco (SLT) use.

BACKGROUND: Chewing tobacco and other types of smokeless tobacco use have had less attention from the global health community than smoked tobacco use. However, the practice is popular in many parts of the world and has been linked to several adverse health outcomes. Understanding trends in prevalence with age, over time, and by location and sex is important for policy setting and in relation to monitoring and assessing commitment to the WHO Framework Convention on Tobacco Control. METHODS: We estimated prevalence of chewing tobacco use as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 using a modelling strategy that used information on multiple types of smokeless tobacco products. We generated a time series of prevalence of chewing tobacco use among individuals aged 15 years and older from 1990 to 2019 in 204 countries and territories, including age-sex specific estimates. We also compared these trends to those of smoked tobacco over the same time period. FINDINGS: In 2019, 273·9 million (95% uncertainty interval 258·5 to 290·9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4·72% (4·46 to 5·01). 228·2 million (213·6 to 244·7; 83·29% [82·15 to 84·42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15-19 years was over 10% in seven locations in 2019. Although global age-standardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: -1·21% [-1·26 to -1·16]), similar progress was not observed for chewing tobacco (0·46% [0·13 to 0·79]). Among the 12 highest prevalence countries (Bangladesh, Bhutan, Cambodia, India, Madagascar, Marshall Islands, Myanmar, Nepal, Pakistan, Palau, Sri Lanka, and Yemen), only Yemen had a significant decrease in the prevalence of chewing tobacco use, which was among males between 1990 and 2019 (-0·94% [-1·72 to -0·14]), compared with nine of 12 countries that had significant decreases in the prevalence of smoking tobacco. Among females, none of these 12 countries had significant decreases in prevalence of chewing tobacco use, whereas seven of 12 countries had a significant decrease in the prevalence of tobacco smoking use for the period. INTERPRETATION: Chewing tobacco remains a substantial public health problem in several regions of the world, and predominantly in south Asia. We found little change in the prevalence of chewing tobacco use between 1990 and 2019, and that control efforts have had much larger effects on the prevalence of smoking tobacco use than on chewing tobacco use in some countries. Mitigating the health effects of chewing tobacco requires stronger regulations and policies that specifically target use of chewing tobacco, especially in countries with high prevalence.

BACKGROUND: Outcomes related to maternal smoked tobacco (cigarette) use have been substantially examined over the past 50 years with resultant public health education targeted towards the reduction of use during pregnancy. However, worldwide the effects of maternal smokeless tobacco use have been less well explored and in Australia, there has been no examination of maternal outcomes in relation to the use of Australian Nicotiana spp. (tobacco plant) as a smokeless tobacco, colloquially known as pituri. The aim of this study is to describe the maternal outcomes of a group of central Australian Aboriginal women in relation to their self-reported tobacco use. METHODS: Eligible participants were > 18 years of age, with a singleton pregnancy, > 28 weeks gestation, and who planned to birth at the Alice Springs Hospital (the major regional hospital for central Australia, in the Northern Territory, Australia). The sample consisted of 73 conveniently recruited women categorized by tobacco-use status as no-tobacco users (n = 31), pituri chewers (n = 19), and smokers (n = 23). RESULTS: There were differences in the groups in relation to teenage pregnancies; 35% of no-tobacco users, compared with 5% of pituri users, and 13% of smokers were < 20 years of age. The chewers had a higher rate (48%) of combined pre-existing and pregnancy-related elevated glucose concentrations compared with smokers (22%) and no-tobacco users (16%).The pituri chewers had the lowest rate (14%) of clinically significant post-partum hemorrhage (> 1000 ml) compared with 22% of smokers and 36% of the no-tobacco users. CONCLUSIONS: This is the first research to examine pituri use in pregnancy and the findings indicate possible associations with a range of adverse maternal outcomes. The use of smokeless tobacco needs to be considered in maternal healthcare assessment to inform antenatal, intrapartum and postpartum care planning. IMPLICATIONS FOR PUBLIC HEALTH: Female smokeless tobacco use is a global phenomenon and is particularly prevalent in low and middle income countries and in Indigenous populations. The findings contribute to the developing knowledge around maternal smokeless tobacco use and maternal outcomes. Maternal screening for a broader range of tobacco and nicotine products is required. NOTE TO READERS: In this research, the central Australian Aboriginal women chose the term 'Aboriginal' to refer to themselves, and 'Indigenous' to refer to the broader First Peoples. That choice has been maintained in the reporting of the research findings.

The city of Clarkston (Georgia) is home to many refugees and immigrants, including Bhutanese and Burmese populations. Use of gutka and paan masala is common in these populations. While gutka and paan masala contain toxic ingredients including carcinogens, little research has examined general use, perceptions of risk, cultural norms, and access to these products among Bhutanese and Burmese populations in the southern U.S. This study uses focus groups and key informant interviews to develop an understanding of gutka and paan masala use among Bhutanese and Burmese refugee populations residing in Clarkston, focusing in particular on knowledge and perceptions of harm, patterns of and reasons for use, access to gutka and paan masala, and resources for cessation and prevention of gutka and paan masala use. We conducted 21 focus groups with Bhutanese and Burmese youths and adults and 11 key informant interviews. We analyzed data using MAXQDA and a grounded theory approach. Emerging themes included mixed understandings of ingredients and harms associated with gutka and paan masala use. The continued use of paan masala was perceived to be due to cultural traditions. Youths, particularly Bhutanese, were perceived as a rising group of users of gutka and paan masala. Widespread availability and accessibility in Clarkston made it easy for both adults and youths to acquire and use gutka and paan masala. Few participants knew about prevention efforts or resources in their communities. In conclusion, culturally-relevant awareness and education programs as well as health promotion materials regarding gutka and paan masala are much needed in Bhutanese and Burmese communities. More regulatory actions are needed, such as better warning signs in businesses to inform customers of ingredients in these products and their health risks, age restrictions on gutka and paan masala purchase, and compliance checks.

Snus is an oral smokeless tobacco product which is usually placed behind the upper lip, either in a loose form or in portioned sachets, and is primarily used in Sweden and Norway. The purpose of this review is to examine the reported effects of snus use in relation to specified health effects, namely lung cancer, cardiovascular disease, pancreatic cancer, diabetes, oral cancer and non-neoplastic oral disease. The review also examines the harm reduction potential of snus as an alternative to cigarettes by comparing the prevalence of snus use and cigarette smoking, and the reported incidence of tobacco-related diseases across European Union countries. The scientific literature generally indicates that the use of snus is not a significant risk factor for developing lung cancer, cardiovascular disease, pancreatic cancer or oral cancer. Studies investigating snus use and diabetes have reported that high consumption of snus (estimated as being four or more cans per week) may be associated with a higher risk of developing diabetes or components of metabolic syndrome; however, overall results are not conclusive. Snus use is associated with the presence of non-neoplastic oral mucosal lesions which are reported to heal rapidly once use has stopped. The most recent Eurobarometer data from 2017 reported that Sweden had the lowest prevalence of daily cigarette use in the European Union at 5% whilst daily "oral tobacco" use was reported to be 20%. European data published by the World Health Organisation in 2018 indicated that Sweden had the lowest rate of tobacco-related mortality and the lowest incidence of male lung cancer. Overall, prevalence statistics and epidemiological data indicate that the use of snus confers a significant harm reduction benefit which is reflected in the comparatively low levels of tobacco-related disease in Sweden when compared with the rest of Europe. The available scientific data, including long-term population studies conducted by independent bodies, demonstrates that the health risks associated with snus are considerably lower than those associated with cigarette smoking.

Smokeless tobacco is consumed by 356 million people globally and is a leading cause of head and neck cancers. However, global efforts to control smokeless tobacco use trail behind the progress made in curbing cigarette consumption. In this Policy Review, we describe the extent of the policy implementation gap in smokeless tobacco control, discuss key reasons on why it exists, and make recommendations on how to bridge this gap. Although 180 countries have agreed that the WHO Framework Convention on Tobacco Control is the best approach to control the demand and supply of smokeless tobacco, only 138 (77%) Parties define smokeless tobacco in their statutes. Only 34 (19%) Parties tax or report taxing smokeless tobacco products, six (3%) measure content and emissions of smokeless tobacco products, and 41 (23%) mandate pictorial health warnings on these products. Although awareness of the harms related to smokeless tobacco is growing in many parts of the world, few Parties collect or present data on smokeless tobacco use under global or national surveillance mechanisms (eg, Global Tobacco Surveillance System and WHO STEPwise). Only 16 (9%) Parties have implemented a comprehensive ban on smokeless tobacco advertisement, promotion, and sponsorships. Globally, a smaller proportion of smokeless tobacco users are advised to quit the use of smokeless tobacco products compared to tobacco users. Use of smokeless tobacco is becoming a global cause of concern, requiring a greater commitment on the full implementation of the WHO Framework Convention on Tobacco Control measures.

BACKGROUND: Gastrointestinal (GI) malignancies are increasing with advancing age. Various addictions and poor dietary habits are among the major risk factors. Early detection is difficult until patient notices symptoms. Primary prevention by knowing various risk factors and early symptom awareness will help in early diagnosis and better treatment outcome. OBJECTIVES: This study is carried out to see various addiction patterns, dietary habits, associated medical problems, and socioeconomic status with various sites involved in GI malignancies, at a tertiary care teaching hospital of Western Maharashtra, India. MATERIALS AND METHODS: Prospective questionnaire-based study was carried out for 11 months. A total of 100 diagnosed carcinoma cases of GI tract malignancy were taken for study. RESULTS AND CONCLUSIONS: Out of total 100 cases, 61 were male and 39 were female. The most common site involved was esophagus (41) followed by rectosigmoid, colon and cecum, stomach, and anal canal (29, 14, 13, and 3, respectively). There were 45% of cases above 60 years of age. The most common addiction was smokeless tobacco. Most of the patients belonged to lower and upper lower class (64%). Majority of cases (81%) were nonvegetarian, only 16% were pure vegetarian. Most of the cases (85%) were in advanced stage of disease (III and IV). Awareness program for harmful effects of various addictions and importance of high-fiber diet (vegetarian diet) will help in health promotion and prevention of various malignancies. Awareness about the early symptoms of GI malignancy will help in early detection of disease and better treatment outcome.

Background: Oral potentially malignant disorders (OPMDs) and oral cancer (OC) are preventable oral mucosal diseases prevalent in Asian region. This epidemiological study aims to identify oral potentially malignant disorders (OPMDs) and oral cancer (OC), confirm histopathologically, and treat or refer these cases among the population of Eastern Development Region (EDR) of Nepal. It also attempts to assess the risk factors associated in order to compare doseresponse measurements of oral habits in these patients. Methods: Cross-sectional epidemiological study was conducted over a period of 2 years in 16 districts of EDR. A total of 3,200 people were screened. A brief history was taken and visual screening examination was conducted in two phases as described by British Columbia Oral Cancer Prevention Program. Suspicious oral lesions were biopsied either by punch or scalpel after toluidine blue staining. Tissue specimen was transported to the institutional lab for histopathological processing. The reports were sent to the patients through the local leaders or organizations. Results: More than 40% of the study population either chewed areca nut and/or tobacco. Eighteen percent were smokers. OPMDs were prevalent among 468 study population with male-female ratio of 3:1. Tobacco pouch keratosis (50.4%) was the most prevalent OPMD, followed by OSF (29.1%). Fifty-two had squamous cell carcinoma and 8 had verrucous carcinoma. Conclusion: Chewing areca nut, tobacco, commercial areca nut/tobacco preparation and smoking being the major risk factors, there is high prevalence of oral cancer and OPMDs in the EDR of Nepal.

Swedish snus is a smokeless tobacco product that contains reduced levels of harmful compounds compared with cigarette smoke. In Sweden, where snus use exceeds smoking among men, relatively low rates of major smoking-related diseases have been recorded. To better understand how snus use could align with current tobacco harm reduction strategies, its potential mechanisms of toxicity must be investigated. This study aimed to determine, via a systems toxicology approach, the biological impact of repeated 72-hour exposure of human gingival epithelial organotypic cultures to extracts from both a commercial and a reference snus and the total particulate matter (TPM) from cigarette smoke. At concentrations relevant for human use, cultures treated with snus extracts induced mild, generally reversible biological changes, while TPM treatment induced substantial morphological and inflammatory alterations. Network enrichment analysis and integrative analysis of the global mRNA and miRNA expression profiles indicated a limited and mostly transient impact of the snus extracts, in particular on xenobiotic metabolism, while the effects of TPM were marked and sustained over time. High-confidence miRNAs that might be related to pathological conditions in vivo were identified. This study highlights the limited biological impact of Swedish snus extract on human organotypic gingival cultures.

AIM: The aim of the present study was to investigate the awareness of oral cancer among adults in Jakarta, Indonesia, and explore the factors influencing it. METHODS: A previously-tested questionnaire on 1000 adults in Jakarta was used in the present study. The data included sociodemographic factors and answers to assess the awareness of oral cancer, early signs and symptoms, risks factors, lifestyles, and history of dental visits. RESULTS: Only 53.2% of participants were aware of oral cancer. The level of awareness significantly differed by level of education, occupation, and experience of dental visits. Only 30% of patients had been asked about their tobacco and alcohol habits, and had been informed about the hazards of these by their dentists. All of the smokers knew that tobacco increased the risk for oral cancer. However, only a few participants considered alcohol, betel quid chewing, UV light exposure, poor diet, and genetics to play role in the development of oral cancer. Health warnings were the main source of information about oral cancer; the role of health professionals is still quite low and needs to be emphasized. CONCLUSION: Oral cancer awareness is still low among adults in Jakarta; this finding was consistent with other studies conducted in Asia. Educational material suited to particular communities is warranted.

This study examined gender differences in patterns of smokeless tobacco (SLT) use among various socioeconomic and demographic segments in Bangladesh and India, which are home to 80 percent of global SLT users and share similar sociocultural milieus. The objective was to provide evidence of whether gender-focused interventions and policies might be helpful for SLT cessation programs. Data from the Global Adult Tobacco Survey were used for the analysis. In Bangladesh, data were collected between July and August 2009, and 9,629 individuals were successfully interviewed. In India, data were collected from June 2009 to January 2010, and 69,296 individuals were interviewed. Tests of proportions revealed that the prevalence of SLT use was highest among women in Bangladesh (27.9 percent) and among men (32.9 percent) in India. Logistic regression models revealed that the odds of SLT use was lower among Bangladeshi females in the highest age category. However, in India, a similar observation was made only for females with rural residences. In addition, the odds of SLT use was less among those with a higher level of education and wealth, irrespective of the sex or country. The present findings suggest a need for gender-specific policies and interventions for SLT control.

OBJECTIVE: Pan Masala containing Tobacco (PMT) use contributes significantly to the overall world tobacco burden especially in south Asian country like Nepal. Oxidative stress caused by it may leads to cardiovascular disease, peripheral vascular disease, hypertension, etc. Therefore, this work proposes to study the antioxidant and oxidative stress along with cardiovascular morbidity in PMT users. RESULTS: Hundred PMT users and 80 non-user controls with age and sex matched were enrolled. There was a significant difference in blood pressure, albumin, uric acid, vitamin C, vitamin E, malondialdehyde (MDA), total cholesterol, triglycerides, low density lipoprotein cholesterol between the two groups (p < 0.001). We observed statistically significant (p < 0.001) decrease in antioxidant and increase oxidative stress in PMT users. Duration and quantity of PMT user were significantly associated with the MDA level.

AIM: To study and compare the genotoxic effects of tobacco using micronuclei count in individuals with different tobacco-related habits. MATERIALS AND METHODS: A cross-sectional study was done comprising 200 individuals, divided into four groups. Group I: 50 subjects with history of tobacco chewing, group II: 50 subjects with a history of smoking tobacco, group III: 50 subjects with a history of both tobacco chewing and smoking, and group IV: 50 subjects without any habits as controls (age-matched). The study groups were individually further divided into three subgroups which comprised of subjects with history of substance abuse for less than 5, 5 to 10, and greater than 10 years. Exfoliated cells from the buccal mucosa of the subjects were collected and stained using Giemsa stain. A total of 1,000 cells were examined for each case and micronuclei frequency was scored according to the guidelines given by Tolbert et al. Results: The mean number of micronuclei count was 18.28 ± 10.0 in group I (smokeless tobacco users), 11.38 ± 6.3 in group II (subjects with history of tobacco smoking), 22.44 ± 9.8 in group III (subjects with history of using both smokeless and smokable form of tobacco), and 4.86 ± 2.4 in the control group. The statistical difference was found to be highly significant (p < 0.001). Similarly, based on the duration, highly significant difference was notable in the mean number of micronuclei in subjects who had a history of substance abuse for more than 10 years. CONCLUSION: A significantly higher micronucleus frequency was found in smokeless tobacco users than in smokers and controls. Micronuclei assay in the exfoliated buccal cells is a useful and minimally invasive method for monitoring early genotoxic damage. CLINICAL SIGNIFICANCE: Micronuclei assay can be used to detect genotoxic damage at the earliest and, if intervened at this point, may prevent frank malignancy, morbidity, and mortality.

BACKGROUND: Oral cancer incidence depends on both qualitative and quantitative factors wherein the incidence of oral cancer in patients with smoking and tobacco chewing habit is 8.4 times higher than that of patients with no habit. AIM: To understand about the prevalence of oral cancer in population of Kanpur reported to the hospital and analyse the association with age, gender and tobacco habit. MATERIAL AND METHOD: All 320 cases of Squamous cell carcinoma diagnosed histopathologically, since January 2007 to December 2016, were retrieved from the archives and a retrospective study was conducted along with association with the variables such as age, gender, site, habit and histopathological type. RESULTS: A total of 71 cases were reported in the age group of 30-39 (22.18%) and 60 cases (18.75%) were seen to be below 30yrs. Among individuals with habit, 135 (42.18%) were tobacco chewers and smoking was prevalent in about 48 (15%). The prevalence was more in males 37 (15.22%). Amongst both males (44.03%) and females (48.05%) gingivo-buccal sulcus was the most common site. The least common site was seen to be lip with only 10 (3.12%) patients. Well differentiated squamous cell carcinoma was common in both males and females with 155 (63.78%) and 47 (61.03%) respectively. Poorly differentiated squamous cell carcinoma was only reported in 4(1.64%) males. CONCLUSION: Early detection of these oral cancers will enable appropriate clinical management and monitoring. Moreover, improving the incidence, mortality, and survival rates of oral cancer requires a multi-tier structural approach that targets society, dentists, communities, and the individual.

Objective: To develop a mass media campaign on oral carcinogens and their effects on the oral cavity in order to increase awareness among the general population. Methods: Documentary and public service announcements highlighting the effects of tobacco and its products were designed and developed based on principles of behavior change. A questionnaire, designed to determine the knowledge, attitude and practice of people regarding oral carcinogens, was used to conduct a baseline survey at various sites in eastern Nepal. Local television channels and radio stations broadcasted the documentary and public service announcements. An evaluation survey was then performed to assess the effectiveness of the campaign. Results: Baseline and evaluation surveys covered 1,972 and 2,140 individuals, respectively. A third of the baseline population consumed quid, 22% chewing tobacco, 16% gutka (commercial preparation of arecanut, tobacco, lime and chemicals) and 25% cigarettes. Tobacco consumption differed significantly between 3 ecologic regions with greater use in the Terai region. The knowledge prevalence regarding the oral carcinogens quid (70%), chewing tobacco (82%), gutka (58%) and cigarettes (93%) significantly increased in the evaluation population. Females were more aware about the various tobacco products and their effects on health. More people knew about the harmful effects of tobacco on their health and oral cavity, and had their mouth examined and the frequency of consumption of these products reduced significantly after the campaign. Attitudes towards production, sale and advertisements of tobacco also improved significantly. Conclusions: The mass media campaign was an effective tool for increasing awareness among the population.

OBJECTIVES/OBJECTIVES: We aimed to provide an otolaryngologist-targeted summary regarding the epidemiology, carcinogenesis, and cessation strategies for smokeless tobacco usage. STUDY DESIGN: Evidence-based literature review. METHODS: We reviewed the current evidence-based literature concerning trends in smokeless tobacco use, associations with neoplastic change, and therapeutic interventions to assist with sustained abstinence. In complement, we present an actual case of laryngeal squamous cell carcinoma in the setting of chronic tobacco-dentifrice usage in a lifelong nonsmoker. RESULTS: This report provides a synopsis of epidemiological data and evidence-based recommendations for general, pharmaceutical, and behavioral cessation strategies. CONCLUSIONS: Smokeless tobacco use continues to be prevalent among patients seen by otolaryngologists, particularly of various Indian and Southeast Asian descent. The data presented in this article will aid in the identification of at risk patients. The provided recommended cessation strategies will tool otolaryngologists for patient counseling and management, ultimately aimed at improving health outcomes. Laryngoscope, 128:2067-2071, 2018.

Background: The full extent of global smokeless tobacco (SLT) use and its association with key demographic factors such as gender, place of residence, and household or country income status is not yet known. Methods: The global burden of SLT use among adults was estimated using nationally representative data of 140 countries by gender and country income group. Countries were grouped in Group 1 (low and low-middle income countries combined) and Group 2 (upper middle and high income countries combined). The number of male and female SLT users was calculated using prevalence and population estimates of corresponding age groups. Results: Nearly one in 10 males and one in 20 females used SLT in some form. SLT use prevalence was significantly higher among males (p < .001) and females (p < .001) in Group 1 countries compared with their counterparts in Group 2 countries. However, for both Group 1 (p < .01) and Group 2 (p < .01), males were more likely to use SLT than females. Nearly 91% of a total 356 million adult SLT users resided in Group 1 countries, with 81.6% in countries of WHO South-East Asia region (SEAR). In SEAR and African region, SLT use was higher in rural areas and poorest communities. Conclusion: The majority of the burden of SLT use is on lower and lower middle income countries with the greatest burden on the poorest segments of the population in these countries. Implications: This study brings the comprehensive information on epidemiology of SLT use among adults at global level. Ninety percent of SLT burden is in low and low-middle income group of countries and more specifically among the poorest group in such countries. These countries need to have strategies to implement different provisions of the WHO Framework Convention on Tobacco Control. The program in such countries should be targeted towards the poorest communities for effective SLT control.

Introduction: This study estimated the health care utilization and expenditures attributable to the use of smokeless tobacco (ST) which includes chewing tobacco, snuff, dip, snus, and dissolvable tobacco among US adults aged 18 and older. Methods: We used data from the 2012-2015 National Health Interview Surveys (n = 139451 adults) to estimate a zero-inflated Poisson (ZIP) regression model on four health care utilization measures among US adults (hospital nights, emergency room [ER] visits, doctor visits, and home care visits) specified as a function of tobacco use status, and other covariates. Tobacco use status was classified into four categories: current ST users, former ST users, non-ST tobacco users, and never tobacco users. ST-attributable utilization was calculated based on the estimated ZIP model using an "excess utilization" approach. It was then multiplied by the unit cost estimated from the 2014 Medical Expenditures Panel Survey data to derive ST-attributable health care expenditures. Results: During 2012-2015, 2.1% of adults were current ST users and 7.7% were former ST users. ST-attributable health care utilization amounted to 681000 hospital nights, 624000 ER visits, and 4.6 million doctor visits per year (home care visits results were not significant). This resulted in annual excess expenditures of $1.8 billion for hospitalizations, $0.7 billion for ER visits, and $0.9 billion for doctor visits, totaling over $3.4 billion (in 2014 dollars). Conclusion: Comprehensive tobacco control policies and interventions are needed to reduce ST use and the associated health care burden. Implications: This is the first study to assess the impact of ST use on health care burden in the United States. Findings indicate that excess annual health care expenditures attributable to ST use for US adults were $3.4 billion in 2014 dollars.
