Existing longitudinal surveys focused on the association between ever use of e-cigarettes and combustible cigarette consumption, making it difficult to infer what characteristics of e-cigarette use could potentially change combustible cigarette use behavior, which may have long-term health consequences. Although e-cigarettes' efficacy of alleviating dependence symptoms was supported by studies conducted in laboratory settings, whether the results can be translated into symptom reduction in the real world and over time is an open question. This study conducted secondary analysis on the Waves 1-2 data of the Population Assessment of Tobacco and Health (PATH) Study to examine the association between e-cigarette use characteristics (frequency, flavoring, and voltage adjustment) and combustible cigarette use outcomes (frequency, quantity, and symptoms), using the Heckman 2-step selection procedure with the selection bias controlled. The inclusion criteria ensured that we followed an adult cohort of exclusive combustible cigarette users at Wave 1. The result shows that higher frequency of e-cigarette use was associated with lower combustible cigarette consumption and dependence symptoms, controlling for the corresponding baseline cigarette use variable and other confounders. Given the frequency of e-cigarette use, the feature of voltage adjustment was not significantly associated with any of the cigarette use outcomes. Flavoring, on the other hand, was associated with lower quantity of cigarette use. Exclusive smokers who start using e-cigarettes do indeed change the frequency and quantity with which they smoke cigarettes. E-cigarette use may also help reduce dependence symptoms.

Recent studies suggest that e-cigarette use among youth may be associated with increased risk of cigarette initiation. The goal of this study was to test the hypothesis that use of e-cigarettes among young adult non-daily cigarette smokers would be associated with increased cigarette consumption. Participants (n=391; 52% male) were 18-24year-old non-daily cigarette smokers recruited from across California. Cigarette and e-cigarette use were assessed online or via mobile phone every three months for one year between March 2015 and December 2016. Longitudinal negative binomial regression models showed that, adjusted for propensity for baseline e-cigarette use, non-daily smokers who reported more frequent use of e-cigarettes upon study entry reported greater quantity and frequency of cigarette smoking at baseline and greater increases in cigarette quantity over 12months than non-daily cigarette only smokers (psnon-daily smokers, young adults who use e-cigarettes tend to smoke more cigarettes and to do so more frequently. Such individuals may be at greater risk for chronic tobacco use and dependence. Copyright © 2017 Elsevier Inc. All rights reserved.

Illicit cigarette consumption has increased worldwide. It is important to understand this problem thoroughly. To investigate behaviours and factors associated with illicit cigarette consumption in southern Thailand. A survey and qualitative study were conducted in a border province in southern Thailand next to Malaysia. A modified snowballing technique was used to recruit 300 illicit and 150 non-illicit cigarette smokers. A questionnaire was used to interview subjects. Illicit cigarette packs were obtained in order to identify their characteristics. Bivariate and multivariate logistic regression was used for data analysis. Smoking of illicit cigarettes has become accepted in the communities. They were available in supermarkets and vendor shops. Friends and other illicit smokers known by illicit cigarette smokers were an important source of information for access to illicit cigarette products. The main factors associated with smoking illicit cigarettes, compared with smoking non-illicit cigarettes, were younger age, higher education and higher average monthly expenditure on cigarettes (most illicit smokers smoked illicit cigarettes (average price per packet = 33 THB (US$1.1), while most non-illicit smokers smoked hand-rolled cigarettes (average price per packet = 7 THB (US$0.2)) and knowledge of other illicit cigarette smokers. The low price of illicit cigarettes was the main reason for their use. Selling strategies included sale of singles, sale in shops and direct sale through social networking. Illicit cigarette consumption has become more acceptable especially among young adult smokers. Age and extent of social networks are important factors associated with smoking illicit cigarettes.

In the United States, analysis of survey data provided by projects such as the National Health Interview Survey and the Youth Tobacco Survey has revealed the extent to which cigarette consumption patterns are influenced by gender and race. Taking our lead from a broader field of research that analyzed the sociological characteristics of cigarette consumption, we analyzed these intersections between race and gender through a study of masculinity and style in Marlboro and Kool cigarette advertisements during the 1960s and 1970s. We focused on this period because it was then that the racial bifurcation of cigarette consumption practices first became apparent. We suggest that style provides both a theoretical framework and methodology for understanding how and why White American and African American male consumers learned to consume in different ways. We also argue that the analysis of tobacco consumption in terms of masculinity and style provides a useful method for approaching the design of antismoking interventions.

The work force in industries are at risk of developing unduly high rates of health and behaviour related problems including abuse of alcohol, betel nut and cigarette (alcohol, betel nut and cigarette consumption). This study describes the relationships between alcohol, betel nut and cigarette consumption and health promoting behaviour among industrial workers. A cross sectional survey was conducted on workers in various industries of Ghaziabad city with concerned authority permission. A sample size of 732 workers was calculated based on pilot study. Through Simple random sampling 732 workers in 20 to 50 years age group with informed consent were interviewed through structured, pretested, validated questionnaire in vernacular language by one calibrated investigator. Data on socio demography, alcohol, betel nut and cigarette consumption pattern and health behaviour were collected. The association between health promoting behaviour and alcohol, betel nut and cigarette consumption was analysed by Logistic regression and Chi-square test through SPSS 16 at pbetel nut and cigarette consumption in study population was 88%. The prevalence of individual alcohol, betel nut and cigarette consumption were 82%, 68% and 79% respectively. Combined alcohol, betel nut and cigarette prevalence in study population was 58%. Alcohol and cigarette users were significantly higher (pbetel nut and cigarette users.

European Union public healthcare expenditure on treating smoking and attributable diseases is estimated at over €25bn annually. The reduction of tobacco consumption has thus become one of the major social policies of the EU. This study investigates the effects of price hikes on cigarette consumption, tobacco tax revenues and smoking-caused deaths in 28 EU countries. Employing panel data for the years 2005 to 2014 from Euromonitor International, the World Bank and the World Health Organization, we used income as a threshold variable and applied threshold regression modelling to estimate the elasticity of cigarette prices and to simulate the effect of price fluctuations. The results showed that there was an income threshold effect on cigarette prices in the 28 EU countries that had a gross national income (GNI) per capita lower than US$5418, with a maximum cigarette price elasticity of -1.227. The results of the simulated analysis showed that a rise of 10% in cigarette price would significantly reduce cigarette consumption as well the total death toll caused by smoking in all the observed countries, but would be most effective in Bulgaria and Romania, followed by Latvia and Poland. Additionally, an increase in the number of MPOWER tobacco control policies at the highest level of achievment would help reduce cigarette consumption. It is recommended that all EU countries levy higher tobacco taxes to increase cigarette prices, and thus in effect reduce cigarette consumption. The subsequent increase in tobacco tax revenues would be instrumental in covering expenditures related to tobacco prevention and control programs.

This study investigates the effects of price hikes on cigarette consumption, tobacco tax revenues, and reduction in smoking-caused mortality in 36 African countries. Using panel data from the 1999-2013 Euromonitor International, the World Bank and the World Health Organization, we applied fixed-effects and random-effects regression models of panel data to estimate the elasticity of cigarette prices and simulate the effect of price fluctuations. Cigarette price elasticity was the highest for low-income countries and considerably lower for other African economies. The administered simulation shows that with an average annual cigarette price increase of 7.38%, the average annual cigarette consumption would decrease by 3.84%, and the average annual tobacco tax revenue would increase by 19.39%. By 2050, the number of averted smoking-attributable deaths (SADs) will be the highest in South Africa, followed by the Democratic Republic of Congo, Madagascar, and Ethiopia. Excise tax increases have a significant effect on the reduction of smoking prevalence and the number of averted smoking-attributable deaths, Low-income countries are most affected by high taxation policies.

In India, 14% of the population use smoked tobacco products. Increasing prices of these products is one of the measures to curb their consumption. This study analyzes "unit price" and "daily consumption" of cigarettes and bidis and investigates their relation with each other. A cross-sectional survey was conducted in four states of India (Bihar, West Bengal, Madhya Pradesh and Maharashtra) as a part of the International Tobacco Control Policy (TCP) Evaluation Project (the TCP India Project) during 2010-2011. Information was collected from adult (aged ≥ 15) daily exclusive smokers of cigarette/bidi regarding (a) last purchase (purchase in pack/loose, brand and price) and (b) daily consumption. Average unit price and daily consumption was calculated for different brands and states. Regression model was used to assess the impact of price on daily consumption. Bidis were much less expensive ([symbol in text]0.39) than cigarettes ([symbol in text]3.1). The daily consumption was higher (14) among bidi smokers than cigarette smokers (8). The prices and daily consumption of bidis ([symbol in text]0.33-0.43; 12-15) and cigarettes ([symbol in text]2.9-3.6; 5-9) varied across the four states. The unit prices of bidis and cigarettes did not influence their daily consumption. Smokers purchasing bidis in packs paid substantially less per unit and purchase of bidis and cigarettes in packs influenced their consumption positively. Cigarettes although more expensive than bidis, seem very cheap if compared internationally. Hence, prices of both cigarettes and bidis do not influence their consumption.

Models measuring the interactions between consumption of conventional cigarettes and electronic cigarettes (e-cigarettes) in the marketplace are becoming vital forecast tools as the popularity of e-cigarettes increases and policy on tobacco products changes. Behavioral economics, which involves the integration of psychology and consumer demand, can be used to measure individuals' purchase behavior under different marketplace conditions. Our goal was to measure hypothetical conventional cigarette and e-cigarette purchasing among smokers with varying e-cigarette use patterns. Daily cigarette smokers were recruited using Amazon Mechanical Turk, an online crowdsourcing tool. Participants were asked about their frequency of e-cigarette use and to complete hypothetical single and cross-commodity purchase tasks. Frequency of e-cigarette use differentially affected how individuals consumed both conventional and e- cigarettes in different hypothetical marketplace conditions. The present study demonstrates four main findings: 1) the demand for conventional cigarettes was the lowest in those with greater frequency of e-cigarette use, 2) the demand for e-cigarettes was the highest in those with greater frequency of e-cigarette use, 3) when both products were available together, daily e-cigarette users purchased more e-cigarettes, but e-cigarettes served as a substitute for cigarettes in all groups regardless of frequency of use, and 4) the demand for conventional cigarette demand was lower in frequent e-cigarette users when e-cigarettes were concurrently available. Together, these data suggest that price and marketplace conditions will impact purchasing behavior of conventional and e-cigarettes users heterogeneously. Therefore, frequency of use patterns should be considered when implementing novel policies and/or marketplace changes. Copyright © 2017 Elsevier B.V. All rights reserved.

[Changes in tobacco consumption: boom of roll-your-own cigarettes and emergence of e-cigarettes].

To assess changes in smoking prevalence and study roll-your-own (RYO) tobacco and e-cigarette use in the Galician population between 2007 and 2015. Data were obtained from five independent, cross-sectional studies carried out in Galicia (Spain) between 2007-2015 in the population aged 16 and over (n=8,000/year). Prevalence of use was estimated, with 95% confidence intervals, overall, according to sex and by age group, area of residence and level of education. Smoking prevalence decreased from 25.4% in 2007 to 21.8% in 2015. In 2007, 1.8% of current smokers declared that they had smoked RYO tobacco, compared to 18.6% in 2015. Among smokers, RYO tobacco consumption increased across all demographic groups. In both 2014 and 2015, ever use of e-cigarettes was 0.7%. E-cigarette use was more frequent in urban settings. Smoking prevalence decreased in Galicia between 2007 and 2015, and there has been rapid growth in the prevalence of RYO tobacco use. Although smokers are more likely to use e-cigarettes, both former and never smokers declared their use. The boom of RYO cigarettes and the emergence of e-cigarettes highlight the importance of having continuous surveillance systems to identify smoking behavioural changes. Copyright © 2016 SESPAS.

Consumption of single cigarettes and quitting behavior: A longitudinal analysis of Mexican smokers

Science.gov (United States)

2011-01-01

Background Previous cross-sectional research has suggested single cigarettes could either promote or inhibit consumption. The present study aimed to assess the effects of single cigarette availability and consumption on downstream quit behavior. Methods We analyzed population-based, longitudinal data from adult smokers who participated in the 2008 and 2010 administrations of the International Tobacco Control Policy Evaluation Survey in Mexico. Results At baseline, 30% of smokers saw single cigarettes for sale on a daily basis, 17% bought singles at their last purchase, and 7% bought singles daily. Smokers who most frequently purchased singles, both in general and specifically to control their consumption, were no more likely to attempt to quit over the 14 month follow-up period than those who did not purchase singles. Frequency of buying singles to reduce consumption had a non-monotonic association with being quit at followup. The odds of being quit was only statistically significant when comparing those who had not bought singles to reduce consumption with those who had done so on a more irregular basis (AOR = 2.30; 95% CI 1.19, 4.45), whereas those who did so more regularly were no more likely to be quit at followup. Frequency of self-reported urges to smoke upon seeing singles for sale was unassociated with either quit attempts or being quit at followup. Conclusions These results suggest that the relationship between singles consumption and quit behavior is complex, with no clear evidence that singles either promote or inhibit downstream quit behavior.

In the 1990s, California led the USA in state-level tobacco control strategies. However, after 2000, California lost ground on cigarette taxes, although it maintained higher levels of smoke-free homes among smokers. Trends in per capita cigarette consumption were assessed through taxed sales data and from self-report in repeated national cross-sectional surveys. Linear regressions identified changes in trends after year 2000 separately for California and the rest of the USA. Using data from each state, a linear regression tested the association between different tobacco control strategies and per capita consumption. Change in self-reported per capita consumption was partitioned into contributions associated with initiation, quitting and reduction in cigarette consumption level. Both taxed cigarette sales and per capita consumption declined rapidly in the USA from 1985 to 2015. Declines were particularly fast in California before 2000 but slowed thereafter. In 2014, per capita consumption in California was 29.4 packs/adult/year, but 90% higher in the rest of the USA. Modelling state-level data, every $1 increase in cigarette taxes reduced consumption by 4.8 (95% CI 2.9 to 6.8) packs/adult/year. Every 5% increase in the proportion of smokers with smoke-free homes reduced consumption by 8.0 (95% CI 7.0 to 8.9) packs/adult/year. The different patterns in California and the rest of the USA are at least partially explained by these two variables. The slow down in per capita consumption in California can be attributed to changes in initiation, quitting and especially smokers reducing their consumption level. Tobacco control strategies need to be continually updated to maintain momentum towards a smoke-free society. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2000-07-01

Full Text Available CONTEXT: Increased hydrogen peroxide has been described in the expired breath condensate (H2O2-E of several lung conditions, such as acute respiratory distress syndrome, chronic obstructive pulmonary disease and asthma. This technique has been advocated as being a simple method for documenting airway inflammation. OBJECTIVE: To evaluate H2O2-E in healthy cigarette smokers, and to determine the acute effects of the consumption of one cigarette on H2O2-E levels. TYPE OF STUDY: Prospective, controlled trial. SETTING: A pulmonary function laboratory in a University Hospital. PARTICIPANTS: Two groups of healthy volunteers: individuals who had never smoked (NS; n=10; 4 men; age = 30.6 ± 6.2 years and current cigarette smokers (S; n=12; 7 men; age = 38.7 ± 9.8. None of the volunteers had respiratory symptoms and all showed normal spirometric tests. INTERVENTION: Expired air was collected from all volunteers through a face mask and a plastic collecting system leading into a flask with dry ice and pure ethanol. Samples from the group S were collected twice, before and half an hour after the combustion of one cigarette. MAIN MEASUREMENTS: Expired hydrogen peroxide using the Gallati and Pracht method. RESULTS: The S and NS groups showed comparable levels of H2O2-E at basal conditions [NS = 0.74 muM (DP 0.24 vs. S = 0.75 muM (DP 0.31]. The smokers showed a significant increase in H2O2-E levels half an hour after the consumption of only one cigarette [0.75 muM (DP 0.31 vs. 0.95 muM (DP 0.22]. CONCLUSION: The present results are consistent with the concept that smokers increase oxidative stress with elevated production of reactive oxygen species, contributing to the development of smoking-related disorders.

Portrayal of tobacco use in prime-time TV dramas: trends and associations with adult cigarette consumption--USA, 1955-2010.

Jamieson, Patrick E; Romer, Daniel

2015-05-01

Although portrayal of television (TV) and movie tobacco use has been linked with initiation of cigarette smoking in adolescents, its association with smoking in adults has not been assessed. Therefore, we examined long-term and annual changes in tobacco portrayal in popular US TV dramas and their associations with comparable trends in national adult cigarette consumption. Tobacco use in 1838 h of popular US TV dramas was coded from 1955-2010. The long-term trend and annual deviations from trend were studied in relation to comparable trends in adult per capita cigarette consumption using correlational and time-series methods that controlled for other potential predictors. TV tobacco portrayal has trended downward since 1955 in line with the historical trend in cigarette consumption. Controlling for changes in cigarette prices and other factors, annual changes of one tobacco instance per episode hour across 2 years of programming were associated with annual change of 38.5 cigarettes per US adult. The decline in TV tobacco portrayal was associated with nearly half the effect of increases in cigarette prices over the study period. The correlation between tobacco portrayal in TV dramas and adult cigarette consumption is consistent with well-established effects of exposure to tobacco cues that create craving for cigarettes in adult smokers. Although tobacco use in TV dramas along with movies has declined over time, portrayal of smoking on screen media should be a focus for future adult tobacco control research and policy.

The price sensitivity of cigarette consumption in Bangladesh: evidence from the International Tobacco Control (ITC) Bangladesh Wave 1 (2009) and Wave 2 (2010) Surveys.

In Bangladesh, the average excise tax on cigarettes accounted for just 38% of the average retail price of cigarettes in 2009, and 45% in 2010. Both these rates are well below the WHO recommended share of 70% of the retail price at a minimum. There is thus ample room for raising taxes on cigarettes in Bangladesh. The objective of the present work was therefore to estimate the price elasticity of demand for cigarettes and the effect of tax increases on the consumption of cigarettes and on tax revenue in Bangladesh. Based on data from Wave 1 (2009) and Wave 2 (2010) of the International Tobacco Control Bangladesh Survey, we estimated the overall impact of a price change on cigarette demand using a two-part model. The total price elasticity of cigarettes was measured by the sum of the elasticity of smoking prevalence and the elasticity of average daily consumption conditional on smoking participation. The price elasticity estimates were used in a simulation model to predict changes in cigarette consumption and tax revenue from tax and price increases. The total price elasticity of demand for cigarettes was estimated at -0.49. The elasticity of smoking prevalence accounted for 59% of the total price elasticity. The price elasticity of cigarette consumption is higher for people belonging to lower socioeconomic status. Increases in taxes would result in a significant reduction in cigarette consumption while increasing tax revenue. Raising cigarette prices through increased taxation could lead to a win-win-win situation in Bangladesh: it would reduce cigarette consumption, increase tobacco tax revenue and potentially decrease socioeconomic inequities.

To investigate the association between cigarette smoking, alcohol drinking, coffee consumption and Parkinson's disease (PD). We selected subjects affected by idiopathic PD, with a Mini-Mental State Examination of > or =24, and controls matched 1 to 1 with cases by age (+/- 2 years) and sex. Controls were randomly selected from the resident list of the same municipality of residence of the cases. We assessed cigarette smoking, alcohol drinking, and coffee consumption preceding the onset of PD or the corresponding time for controls using a structured questionnaire, which also evaluated the duration and dose of exposure. Using conditional logistic regression analysis, we calculated adjusted OR and 95% CI. We interviewed 150 PD patients and 150 matched controls. Cigarette smoking (ever vs. never smokers OR = 0.66, 95% CI = 0.41-1.05, p = 0.08) did not show a statistically significant association with PD. We observed an inverse association between alcohol drinking (ever vs. never OR = 0.61, 95% CI = 0.39-0.97, p = 0.037) and coffee consumption (ever vs. never OR = 0.16, 95% CI 0.05-0.46, p = 0.0001) and PD. These associations remained significant after adjustment for other covariates: OR for ever vs. never alcohol consumption was 0.62 (95% CI = 0.43-0.89, p = 0.009) and that for coffee drinking 0.19 (95% CI = 0.07-0.52, p = 0.001). Heavy coffee consumption confirmed the inverse association between coffee and PD (more than 81 cup/year vs. none: OR = 0.20, 95% CI = 0.08-0.47, p coffee drinking, alcohol consumption and PD. The multiple inverse association observed may indicate a complex interaction between genetic and environmental factors. Copyright 2003 S. Karger AG, Basel

Partial correlation analyses, controlling for sensation-seeking tendencies and behaviors, revealed that listening to conventional music (pop, country, and religious genres) was negatively correlated with cigarette smoking (p=.001) and marijuana use (pmusic (rap or hip-hop and soul or funk genres) was positively correlated with marijuana use (p=.004). The only significant predictor of alcohol use was country music, with which it was positively correlated (p=.04). This research suggests an especially harmful influence of energetic music on marijuana use. © The Author(s) 2015.

To examine cigarette purchasing patterns of current smokers and to determine the effects of cigarette price on use of cheaper sources, discount/generic cigarettes, and coupons. Higher cigarette prices result in decreased cigarette consumption, but price sensitive smokers may seek lower priced or tax-free cigarette sources, especially if they are readily available. This price avoidance behaviour costs states excise tax money and dampens the health impact of higher cigarette prices. Telephone survey data from 3602 US smokers who were originally in the COMMIT (community intervention trial for smoking cessation) study were analysed to assess cigarette purchase patterns, use of discount/generic cigarettes, and use of coupons. 59% reported engaging in a high price avoidance strategy, including 34% who regularly purchase from a low or untaxed venue, 28% who smoke a discount/generic cigarette brand, and 18% who report using cigarette coupons more frequently that they did five years ago. The report of engaging in a price avoidance strategy was associated with living within 40 miles of a state or Indian reservation with lower cigarette excise taxes, higher average cigarette consumption, white, non-Hispanic race/ethnicity, and female sex. Data from this study indicate that most smokers are price sensitive and seek out measures to purchase less expensive cigarettes, which may decrease future cessation efforts.

A reduced risk for Parkinson's disease (PD) among cigarette smokers has been observed consistently during the past 30 years. Recent evidence suggests that caffeine may also be protective. Findings are presented regarding associations of PD with smoking, caffeine intake, and alcohol consumption from a case-control study conducted in western Washington State in 1992-2000. Incident PD cases (n = 210) and controls (n = 347), frequency matched on gender and age were identified from enrollees of the Group Health Cooperative health maintenance organization. Exposure data were obtained by in-person questionnaires. Ever having smoked cigarettes was associated with a reduced risk of PD (odds ratio (OR) = 0.5, 95% confidence interval (CI): 0.4, 0.8). A stronger relation was found among current smokers (OR = 0.3, 95% CI: 0.1, 0.7) than among ex-smokers (OR = 0.6, 95% CI: 0.4, 0.9), and there was an inverse gradient with pack-years smoked (trend p coffee consumption or total caffeine intake or for alcohol consumption. However, reduced risks were observed for consumption of 2 cups/day or more of tea (OR = 0.4, 95% CI: 0.2, 0.9) and two or more cola drinks/day (OR = 0.6, 95% CI: 0.3, 1.4). The associations for tea and cola drinks were not confounded by smoking or coffee consumption.

Abstract Objective To use the relation between cigarette consumption and cardiovascular disease to quantify the risk of coronary heart disease and stroke for light smoking (one to five cigarettes/day). Design Systematic review and meta-analysis. Data sources Medline 1946 to May 2015, with manual searches of references. Eligibility criteria for selecting studies Prospective cohort studies with at least 50 events, reporting hazard ratios or relative risks (both hereafter referred to as relative risk) compared with never smokers or age specific incidence in relation to risk of coronary heart disease or stroke. Data extraction/synthesis MOOSE guidelines were followed. For each study, the relative risk was estimated for smoking one, five, or 20 cigarettes per day by using regression modelling between risk and cigarette consumption. Relative risks were adjusted for at least age and often additional confounders. The main measure was the excess relative risk for smoking one cigarette per day (RR1_per_day−1) expressed as a proportion of that for smoking 20 cigarettes per day (RR20_per_day−1), expected to be about 5% assuming a linear relation between risk and consumption (as seen with lung cancer). The relative risks for one, five, and 20 cigarettes per day were also pooled across all studies in a random effects meta-analysis. Separate analyses were done for each combination of sex and disorder. Results The meta-analysis included 55 publications containing 141 cohort studies. Among men, the pooled relative risk for coronary heart disease was 1.48 for smoking one cigarette per day and 2.04 for 20 cigarettes per day, using all studies, but 1.74 and 2.27 among studies in which the relative risk had been adjusted for multiple confounders. Among women, the pooled relative risks were 1.57 and 2.84 for one and 20 cigarettes per day (or 2.19 and 3.95 using relative risks adjusted for multiple factors). Men who smoked one cigarette per day had 46% of the excess relative risk for

To explore how advertising affects demand for cigarettes and potential substitutes, including snus, dissolvable tobacco, and medicinal nicotine. A Web-based experiment randomized 1062 smokers to see advertisements for alternative nicotine products or soft drinks, then complete a series of purchase tasks, which were used to estimate demand elasticity, peak consumption, and cross-price elasticity (CPE) for tobacco products. Lower demand elasticity and greater peak consumption were seen for cigarettes compared to all alternative products (p demand. These findings suggest significantly lower demand for alternative nicotine sources among smokers than previously revealed.

INTRODUCTION Researchers and regulators need to know how changes to cigarette packages can influence population health. We sought to advance research on the role of cigarette packaging by assessing a theory-informed framework from the fields of design and consumer research. The selected Context of Consumption Framework posits cognitive, affective, and behavioral responses to visual design. To assess the Framework’s potential for guiding research on the visual design of cigarette packaging in the U.S., this study seeks to understand to what extent the Context of Consumption Framework converges with how adult smokers think and talk about cigarette pack designs. METHODS Data for this qualitative study came from six telephone-based focus groups conducted in March 2017. Two groups consisted of lesbian, gay, and bisexual participants; two groups of participants with less than four years college education; one group of LGB and straight identity; and one group the general population. All groups were selected for regional, gender, and racial/ethnic diversity. Participants (n=33) represented all nine U.S. Census divisions. We conducted a deductive qualitative analysis. RESULTS Cigarette package designs captured the participants’ attention, suggested the characteristics of the product, and reflected (or could be leveraged to convey) multiple dimensions of consumer identity. Particular to the affective responses to design, our participants shared that cigarette packaging conveyed how the pack could be used to particular ends, created an emotional response to the designs, complied with normative expectations of a cigarette, elicited interest when designs change, and prompted fascination when unique design characteristics are used. CONCLUSIONS Use of the Context of Consumption Framework for cigarette product packaging design can inform regulatory research on tobacco product packaging.

According to survey data, the prevalence of Americans' self-reported cigarette smoking is dropping steadily. However, the accuracy of national surveys has been questioned because of declining response rates and the increasing stigmatization of smoking. We used data from 2 repeated, cross-sectional, nationally representative health surveys (National Survey on Drug Use and Health (NSDUH), 1979-2014; and National Health Interview Survey (NHIS), 1965-2015) to determine whether self-reported cigarette consumption has changed over time as a proportion of federally taxed cigarette sales. From each survey, we calculated national equivalents of annual cigarette consumption. From 1979 to 1997, the amount of cigarettes that NSDUH and NHIS respondents reported corresponded to an average of 59.5% (standard deviation (SD), 2.3%) and 65.6% (SD, 3.2%), respectively, of taxed cigarette sales. After 1997, respondents' reported smoking data corresponded to the equivalent of an average of 64.2% (SD, 5.9%) and 63.3% (SD, 2.5%), respectively, of taxed cigarette sales. NHIS figures remained steady throughout the latter period, with a decline during 2013-2015 from 65.9% to 61.1%. NSDUH figures increased steadily, exceeding those of the NHIS after 2002. Given the consistent underreporting of cigarette consumption over time, these surveys are likely not less accurate than they were previously. The recent decrease in NHIS accuracy, however, gives pause about the magnitude of the reported decline in smoking prevalence in 2014 and 2015. Improvement in the accuracy of NSDUH data is encouraging. © The Author(s) 2017. Published by Oxford University Press on behalf of the Johns Hopkins Bloomberg School of Public Health.

Although several studies have suggested opium as a risk factor for cancers of the esophagus, stomach, larynx, lung, and bladder, no previous study has examined the association of opium with pancreatic cancer. We aimed to study the association between opium use and risk of pancreatic cancer in Iran, using a case-control design. We also studied the association of cigarette smoking and alcohol consumption with pancreatic cancer, for which little information was available from this population. Cases and controls were selected from patients who were referred to 4 endoscopic ultrasound centers in Tehran, Iran. We recruited 316 histopathologically (all adenocarcinoma) and 41 clinically diagnosed incident cases of pancreatic cancer, as well as 328 controls from those with a normal pancreas in enodosonography from January 2011 to January 2015. We used logistic regression models to calculate odds ratios (ORs) and 95% confidence intervals (CIs). After adjustment for potential confounders, opium use (OR 1.91; 95% CI 1.06-3.43) and alcohol consumption (OR 4.16; 95% CI 1.86-9.31) were significantly associated with an increased risk of pancreatic cancer. We did not find an association between ever tobacco smoking and pancreatic cancer risk (OR 0.93; 95% CI 0.62-1.39). In our study, opium use and alcohol consumption were associated with an increased risk of pancreatic cancer, whereas cigarette smoking was not.

The carcinogenic effect of 210 Po and 210 Pb on lung cancer is an important problem in many countries with very high cigarette consumption. Poland has one of the highest consumption of cigarettes in the world. The results of 210 Po determination in fourteen most frequently smoked brands of cigarettes which constitute over 70% total cigarette consumption in Poland, are presented and discussed. Moreover, polonium content in cigarette smoke was estimated on the basis of its activity in fresh tobacco, ash, fresh filter and post smoking filter. The annual effective doses were calculated on the basis of 210 Po and 210 Pb inhalation with cigarette smoke. The results of this work indicate that Polish smokers who smoke one pack (20 cigarettes) per day inhale from 20 to 215 mBq of 210 Po and 210 Pb (each of them). The highest 210 Po content per sample was found in the cheep 'Popularne' brand (24.12 mBq), the lowest in 'Caro' (4.23 mBq). The mean values and annual effective dose for smokers were estimated to be 35 and 70 μSv from 210 Po and 210 Pb, respectively. For persons who smoke 2 packs of cigarettes with higher radionuclide concentrations, the effective dose is much higher (471 μSv/y) in comparison with intake in diet. Therefore, cigarettes and the absorption through the respiratory system are the main sources and principal pathway of 210 Po and 210 Pb intake of smokers in Poland. (author)

Use of other tobacco products (OTPs) among smokers is increasing. Little is known about types of OTP used and the reasons for use, and how OTP use and reasons for use correlate with smoking patterns and nicotine dependence in daily and nondaily smokers. This paper addresses these gaps in the literature. 656 daily smokers and 203 nondaily smokers provided information on their use of different OTPs (hookah, e-cigarettes, chew/snuff, snus, cigars, dissolvables), and reasons for using OTPs (e.g., "to cut down on smoking"), as well as their cigarette consumption and nicotine dependence. Logistic regression models assessed the association of smoking status with OTP use (ever and current) and reasons for use. Within each smoking group, separate logistic regression models examined the associations of OTP use and reasons for use with cigarette consumption and nicotine dependence. Compared to daily smokers, nondaily smokers were more likely to use hookah and cigars, less likely to use dissolvables, and less likely to endorse using OTPs to reduce their smoking. Among non-daily smokers, nicotine dependence was associated with a higher likelihood of current OTP use (OR=1.04 [95% CI 1.01-1.07]; p<0.05), whereas cigarette consumption was not. Results suggest OTP use in nondaily smokers does not correlate with less frequent smoking, but may correlate with higher nicotine dependence. Use of combustible OTPs among nondaily smokers may offset any potential benefits achieved through less frequent cigarette consumption. Providers should explicitly address OTP use when discussing cigarette cessation and reduction. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To assess the effect of the opening of the Taiwanese cigarette market on cigarette consumption, changes in market share, and the effects on tobacco control efforts. With the use of key word "Taiwan", the Legacy Tobacco Documents Library of the University of California, San Francisco, was searched for internal documents related to smuggling activities, promotion of light cigarettes, and market share analyses in Taiwan. Age adjusted smoking rates and cigarette and betel quid consumption before and after market opening were compared. By 2000, the market share of imported cigarettes increased from less than 2% in 1986 to nearly 50%, and per capita cigarette consumption increased 15% following market opening. Because of the sharp increase in smuggling, with contraband cigarettes being as popular as legal imports, and the rapid proliferation of retail outlets, such as betel quid stalls, the market penetration by foreign tobacco companies was greater in Taiwan than among the other Super 301 Asian countries. Aggressive cigarette marketing strategies were associated with a 6% increase in adult male smoking prevalence, and with a 13% increase in the youth rate, within three years after market opening. The market opening also had an incidental effect on increasing the popularity of betel quid. Betel quid chewing has since become a major public health problem in Taiwan. The opening of the cigarette market in 1987 had a long lasting impact on Taiwan. It increased smoking prevalence and the market has become dominated by foreign companies. The seriousness of smuggling and its associated loss of revenue by the government, the extent of increased youth smoking and its associated future health care costs, and the increased use of betel quid and the associated doubling of oral cancer mortality rates each pose significant problems to Taiwan. However, the market opening galvanised anti-smoking sentiment and forced the government to initiate and intensify a series of tobacco control

Previous epidemiological studies found a negative association between cigarette smoking, tea or coffee drinking with the occurrence of Parkinson's disease (PD). However, it is unknown how these factors affect the rate of progression of the disease. A retrospective study was conducted among 278 consecutive PD patients. Data on smoking and coffee or tea consumption were obtained through direct or proxy interviews, and the time from onset of motor symptoms until reaching Hoehn & Yahr (H&Y) stage 3 was retrieved from the case records. Cox proportional hazards model and Kaplan-Meyer model were used to estimate whether the dependent variables (smoking, drinking coffee or tea) affect the rate of progression of the disease, which was measured by the time it took patients to reach H&Y stage 3. We found that disease progression was not affected by cigarette smoking, tea or coffee consumption. The present study suggests that these variables do not have a disease modifying effect in already diagnosed PD patients.

Are lower income smokers more price sensitive?: the evidence from Korean cigarette tax increases.

Science.gov (United States)

Choi, Seng Eun

2016-03-01

smokers are more responsive to changes in the price of cigarettes. While the overall price elasticity of cigarettes is estimated to be -0.425, the price elasticity of the lowest income quartile is estimated to be -0.812, whereas that of the highest income quartile is estimated to be -0.325. The estimated price elasticities of different income groups imply that the cigarette tax and price increases in Korea would reduce smoking more in those with lower incomes. For a given price increase, the percentage reduction in cigarette consumption among smokers in the lowest income quartile is 2.5 times greater than among smokers in the top income quartile. The simulated tax burdens of different income groups show that the additional burden of a tax increase and the associated price rise is largely borne by higher income smokers.

Cigarette tax avoidance and evasion.

Science.gov (United States)

Stehr, Mark

2005-03-01

Variation in state cigarette taxes provides incentives for tax avoidance through smuggling, legal border crossing to low tax jurisdictions, or Internet purchasing. When taxes rise, tax paid sales of cigarettes will decline both because consumption will decrease and because tax avoidance will increase. The key innovation of this paper is to compare cigarette sales data to cigarette consumption data from the Behavioral Risk Factor Surveillance System (BRFSS). I show that after subtracting percent changes in consumption, residual percent changes in sales are associated with state cigarette tax changes implying the existence of tax avoidance. I estimate that the tax avoidance response to tax changes is at least twice the consumption response and that tax avoidance accounted for up to 9.6% of sales between 1985 and 2001. Because of the increase in tax avoidance, tax paid sales data understate the level of smoking and overstate the drop in smoking. I also find that the level of legal border crossing was very low relative to other forms of tax avoidance. If states have strong preferences for smoking control, they must pair high cigarette taxes with effective policies to curb smuggling and other forms of tax avoidance or employ alternative policies such as counter-advertising and smoking restrictions.

A Quantitative Epigenetic Approach for the Assessment of Cigarette Consumption

Directory of Open Access Journals (Sweden)

Robert ePhilibert

2015-06-01

Full Text Available Smoking is the largest preventable cause of morbidity and mortality in the world. Despite the development of numerous preventive and treatment interventions, the rate of daily smoking in the United States is still approximately 22%. Effective psychosocial interventions and pharmacologic agents exist for the prevention and treatment of smoking. Unfortunately, both approaches are hindered by our inability to accurately quantify amount of cigarette consumption from the point of initial experimentation to the point of total dependency . Recently, we and others have demonstrated that smoking is associated with genome-wide changes in DNA methylation. However, whether this advance in basic science can be employed as a reliable assay that is useful for clinical diagnosis and treatment has not been shown. In this communication, we determine the sensitivity and specificity of five of the most consistently replicated CpG loci with respect to smoking status using data from a publically available dataset. We show that methylation status at a CpG locus in the aryl hydrocarbon receptor repressor, cg05575921, is both sensitive and specific for smoking status in adults with a receiver operated curve characteristic (ROC area under the curve of 0.99. Given recent demonstrations that methylation at this locus reflects both intensity of smoking and the degree of smoking cessation, we conclude that a methylation-based diagnostic at this locus could have a prominent role in understanding the impact of new products, such as e-cigarettes on initiation of cigarette smoking among adolescents, while improving the prevention and treatment of smoking and smoking related disorders.

Tobacco advertising can create false beliefs about health harms that are reinforced by product design features. Reduced nicotine content (RNC) cigarettes may reduce harm, but research has not addressed advertising influences. This study examined RNC cigarette advertising effects on false harm beliefs, and how these beliefs - along with initial subjective ratings of RNC cigarettes - affect subsequent smoking behaviors. We further explored whether subjective ratings moderate associations between false beliefs and behavior. Seventy-seven daily, non-treatment-seeking smokers (66.2% male) participated in the first 15days of a randomized, controlled, open-label RNC cigarette trial. Participants viewed an RNC cigarette advertisement at baseline before completing a 5-day period of preferred brand cigarette use, followed by a 10-day period of RNC cigarette use (0.6mg nicotine yield). Participants provided pre- and post-advertisement beliefs, and subjective ratings and smoking behaviors for cigarettes smoked during laboratory visits. Viewing the advertisement increased beliefs that RNC cigarettes contain less nicotine and are healthier than regular cigarettes (p'saffected smoking behaviors. Significant interactions of strength and taste ratings with beliefs (p'ssmokers with less negative initial subjective ratings, greater false beliefs were associated with greater RNC cigarette consumption. Smokers may misconstrue RNC cigarettes as less harmful than regular cigarettes. These beliefs, in conjunction with favorable subjective ratings, may increase product use.

We estimated the price and income elasticity of cigarette demand and the impact of cigarette taxes on cigarette demand and cigarette tax revenue in Malaysia. The data on cigarette consumption, cigarette prices, and public policies between 1990 and 2004 were subjected to a time-series regression analysis applying the error-correction model. The preferred cigarette demand model specification resulted in long-run and short-run price elasticities estimates of -0.57 and -0.08, respectively. Income was positively related to cigarette consumption: A 1% increase in real income increased cigarette consumption by 1.46%. The model predicted that an increase in cigarette excise tax from Malaysian ringgit (RM) 1.60 to RM2.00 per pack would reduce cigarette consumption in Malaysia by 3.37%, or by 806,468,873 cigarettes. This reduction would translate to almost 165 fewer tobacco-related lung cancer deaths per year and a 20.8% increase in the government excise tax revenue. We conclude that taxation is an effective method of reducing cigarette consumption and tobacco-related deaths while increasing revenue for the government of Malaysia.

An empirical analysis of cigarette demand in Argentina.

Martinez, Eugenio; Mejia, Raul; Pérez-Stable, Eliseo J

2015-01-01

To estimate the long-term and short-term effects on cigarette demand in Argentina based on changes in cigarette price and income per person >14 years old. Public data from the Ministry of Economics and Production were analysed based on monthly time series data between 1994 and 2010. The econometric analysis used cigarette consumption per person >14 years of age as the dependent variable and the real income per person >14 years old and the real average price of cigarettes as independent variables. Empirical analyses were done to verify the order of integration of the variables, to test for cointegration to capture the long-term effects and to capture the short-term dynamics of the variables. The demand for cigarettes in Argentina was affected by changes in real income and the real average price of cigarettes. The long-term income elasticity was equal to 0.43, while the own-price elasticity was equal to -0.31, indicating a 10% increase in the growth of real income led to an increase in cigarette consumption of 4.3% and a 10% increase in the price produced a fall of 3.1% in cigarette consumption. The vector error correction model estimated that the short-term income elasticity was 0.25 and the short-term own-price elasticity of cigarette demand was -0.15. A simulation exercise showed that increasing the price of cigarettes by 110% would maximise revenues and result in a potentially large decrease in total cigarette consumption. Econometric analyses of cigarette consumption and their relationship with cigarette price and income can provide valuable information for developing cigarette price policy.

This study assessed the impact of brief exposure to four electronic cigarette (e-cigarette) print advertisements (ads) on perceptions, intention, and subsequent use of e-cigarettes and cigarettes in US young adults. A randomized controlled trial was conducted in a national sample of young adults from an online panel survey in 2013. Participants were randomized to ad exposure or control. Curiosity, intentions, and perceptions regarding e-cigarettes were assessed post-exposure and e-cigarette and cigarette use at 6-month follow-up. Analyses were conducted in 2014. Approximately 6% of young adults who had never used an e-cigarette at baseline tried an e-cigarette at 6-month follow-up, half of whom were current cigarette smokers at baseline. Compared to the control group, ad exposure was associated with greater curiosity to try an e-cigarette (18.3% exposed vs. 11.3% unexposed, AOR = 1.63, 95% CI = 1.18, 2.26) among never e-cigarette users and greater likelihood of e-cigarette trial at follow-up (3.6% exposed vs. 1.2% unexposed, AOR = 2.85; 95% CI = 1.07, 7.61) among never users of cigarettes and e-cigarettes. Exploratory analyses did not find an association between ad exposure and cigarette trial or past 30-day use among never users, nor cigarette use among smokers over time. Curiosity mediated the relationship between ad exposure and e-cigarette trial among e-cigarette never users. Exposure to e-cigarette ads may enhance curiosity and limited trial of e-cigarettes in never users. Future studies are needed to examine the net effect of curiosity and trial of e-cigarettes on longer-term patterns of tobacco use. This randomized trial provides the first evidence of the effect of e-cigarette advertising on a behavioral outcome in young adults. Compared to the control group, ad exposure was associated with greater curiosity to try an e-cigarette among never e-cigarette users and greater likelihood of e-cigarette trial at follow-up in a small number of never e-cigarette

Full Text Available Increasing evidence indicates that cigarette smoking is a strong predictor of electronic cigarettes (e-cigarettes use, particularly in adolescents, yet the effects has not be systematically reviewed and quantified. Relevant studies were retrieved by searching three databases up to June 2015. The meta-analysis results were presented as pooled odds ratios (ORs with 95% confidence intervals (CIs calculated by a random-effects model. Current smokers were more likely to use e-cigarette currently (OR: 14.89, 95% CI: 7.70–28.78 and the probability was greater in adolescents than in adults (39.13 vs. 7.51. The probability of ever e-cigarettes use was significantly increased in smokers (OR: 14.67, 95% CI: 11.04–19.49. Compared with ever smokers and adults, the probabilities were much greater in current smokers (16.10 vs. 9.47 and adolescents (15.19 vs. 14.30, respectively. Cigarette smoking increases the probability of e-cigarettes use, especially in current smokers and adolescents.

Smoking is the first cause of preventable death in France and in the world. Without help, it was shown that 80 % of smokers who try to quit smoking relapse after one month with a low long-term success rate. Smoking reduction can concern smokers who did not want to quit or failed in their attempt to weaning. The final aim is to increase attractiveness of drug therapies by developing new products, such as electronic cigarettes, that can compete cigarette without reproducing its harmful effects. Assess the capacity of electronic cigarettes to reduce or stop tobacco use among regular smokers. Consultations MEDLINE and COCHRANE databases. e-cigarette; electronic cigarettes; ENDD (electronic nicotine delivery system); ENDS (electronic nicotine delivery device); vaping were used. Randomized controlled trials (RCTs) comparing the electronic cigarette with nicotine versus placebo device. Two randomized controlled trials were included in the quantitative analysis. The nicotine electronic cigarette users have tobacco consumption significantly decreased compared to the placebo group (RR: 1.30, 95 % CI [1.02 to 1.66]) at 6 months. Smoking cessation rate at 3 months was greater with the electronic cigarette contains nicotine (RR: 2.55, 95 % CI [1.31 to 4.98]). The small number of RCTs included does not allow definitive conclusions about the effectiveness of electronic cigarettes, especially in the medium to long term. The use of electronic cigarette with nicotine decreases tobacco consumption among regular smokers. Further studies are needed to specify electronic cigarettes safety profile and its ability to cause a reduction in consumption and a long-term cessation in smokers.

Full Text Available We investigated the independent and combined effects of alcohol consumption, cigarette smoking and metabolic syndrome on abnormal liver function, i.e., the elevation of serum liver enzyme levels. Participants of a Korean population-based prospective cohort aged ≥30 years without liver disease, diabetes, or cardiovascular diseases were included. Information on alcohol consumption, smoking status, and metabolic syndrome, defined as per the criteria of the Adult Treatment Panel III, were applied to evaluate their impact on serum levels of aspartate aminotransferase (AST, alanine aminotransferase (ALT, and gamma-glutamyl transferase (GGT. Alcohol consumption, cigarette smoking and metabolic syndrome were the significant individual factors that elevated serum liver enzyme levels. Supra-additive effects of metabolic syndrome and either alcohol consumption or cigarette smoking were also identified. The combination of heavy drinking (≥24 g/day and metabolic syndrome conferred an effect that was higher than the sum of the two individual effects (Synergic Index (SI: AST, 2.37 [1.20-4.67]; GGT, 1.91 [1.17-3.13]. Only GGT level (odds ratio 6.04 [3.68-9.94], SI 2.33 [1.24-4.41] was significantly elevated when the effect of moderate drinking (20 pack years, 1.80 for ≥24 g/day and ≤20 pack years, 2.03 for ≥24 g/day and >20 pack years, while only the combined effect of drinking ≥24 g/day and smoking >20 pack years elevated the AST level (SI 4.55 [3.12-6.61]. The combined effect of cigarette smoking and metabolic syndrome was not supra-additive. To prevent fatty liver disease and other related diseases, a multifactorial prevention strategy that includes limited alcohol consumption, smoking cessation and rectification of adverse metabolic profiles is required.

We examined 1) changes in smoking and vaping behavior and associated cotinine levels and health status among regular smokers who were first-time e-cigarette purchasers and 2) attitudes, intentions, and restrictions regarding e-cigarettes. We conducted a pilot longitudinal study with assessments of the aforementioned factors and salivary cotinine at weeks 0, 4, and 8. Eligibility criteria included being ≥18 years old, smoking ≥25 of the last 30 days, smoking ≥5 cigarettes per day (cpd), smoking regularly ≥1 year, and not having started using e-cigarettes. Of 72 individuals screened, 40 consented, 36 completed the baseline survey, and 83.3% and 72.2% were retained at weeks 4 and 8, respectively. Participants reduced cigarette consumption from baseline to week 4 and 8 (p's e-cigarettes versus regular cigarettes have fewer health risks (97.2%) and that e-cigarettes have been shown to help smokers quit (80.6%) and reduce cigarette consumption (97.2%). In addition, the majority intended to use e-cigarettes as a complete replacement for regular cigarettes (69.4%) and reported no restriction on e-cigarette use in the home (63.9%) or car (80.6%). Future research is needed to document the long-term impact on smoking behavior and health among cigarette smokers who initiate use of e-cigarettes.

Cigarette consumption in Ukraine is increasing while the cigarettes are becoming more affordable due to low taxes and raising income. The impact of cigarette prices and taxes on cigarette consumption is unclear due to the limited research evidence using the local data. This study estimates the sensitivity of Ukraine population to cigarette prices and the affordability of cigarettes using the macro level data in order to predict the effectiveness of cigarette tax policy. Monthly time-series data available from 1997 to 2006 in Ukraine were used to estimate the generalized least square model with an AR(1) process to investigate the impact of cigarette price/tax, household income, the affordability of cigarettes and the volume of tobacco advertising on Ukraine domestic cigarette sales while controlling for other factors. Our analyses demonstrate a strong positive association between cigarette sales and household income as well as a strong positive association between cigarette sales and tobacco advertising activity. The population is found to have relatively low sensitivity to cigarette prices and cigarette taxes, but the impact of cigarettes' affordability is statistically significant, even though also of low magnitude. We speculate that the lower sensitivity to cigarette prices among Ukraine population is caused by wide price variation allowing smokers to avoid a price increase by brand substitution as well as by low costs of cigarettes, high social acceptance of smoking and limited effort to control tobacco use in Ukraine. Narrowing the cigarette price choices and increasing cigarette prices above the level of inflation and income growth by adopting the appropriate tax policy would likely increase the effectiveness of this tool for controlling the smoking rate in Ukraine as well as yield additional budget revenue gains. In addition, imposing advertising restriction may further help reducing the smoking prevalence.

The majority of cigarettes sold in the United States and abroad feature filter ventilation holes designed to dilute mainstream smoke. Although initially intended to produce a safer cigarette, data instead suggest that filter ventilation increases total harm from smoking. In the present study, we examined the effects of blocking ventilation holes on behavioral economic demand for cigarettes (i.e., consumption as a function of price). In a within-subjects design, regular smokers (N = 15) of ventilated cigarettes sampled vent-blocked cigarettes for 3 days. Subsequently, they completed three sessions in which they used an experimental income to purchase vent-blocked and/or control cigarettes across a range of prices. Participants also completed the Drug Effects/Liking Scale. In sessions in which only one cigarette type was available, demand measures were undifferentiated between cigarette types. However, in sessions in which both cigarettes were available at equivalent prices, significantly greater preference for ventilated control cigarettes emerged in demand measures. Regardless of session type, participants also rated vent-blocked cigarettes more poorly in the Drug Effects/Liking Scale (more bad effects, fewer good effects, and less liking, desire, and less likely to use again). Removing filter ventilation reduced cigarette abuse liability, as measured by behavioral economic demand and the Drug Effects/Liking Scale. However, reduced demand was only apparent when both cigarette types were concurrently available. This selective effect suggests that regulatory action banning filter ventilation would only reduce cigarette consumption when effective substitutes for vent-blocked cigarettes are available. This preliminary study indicates that regulatory action designed to ban or restrict cigarette filter ventilation may decrease cigarette abuse liability as measured by both behavioral economic demand and self-report measures. However, effects of removing filter ventilation

The Substitutability of Cigarettes and Food: A Behavioral Economic Comparison in Normal Weight and Overweight or Obese Smokers

Obesity and cigarette smoking contribute to a multitude of preventable deaths in the US and eating and smoking behavior may influence each other. The field of behavioral economics integrates principles from psychology and economics and permits systematic examination of how commodities interrelate with one another. Using this framework, the current study evaluated the effects of rising food and cigarette prices on consumption to investigate their substitutability and their relationship to BMI and associated variables. Behavioral economics categorizes commodities as substitutable when the consumption of one increases as a function of a price increase in the other. Smokers (N = 86) completed a two-part hypothetical task in which money was allocated to purchase cigarettes and fast food-style reinforcers (e.g., hamburgers, ice cream) at various prices. Results indicated that food and cigarettes were not substitutes for one another (cross-price elasticity coefficients > .20). Food purchases were independent of cigarette price, whereas cigarette purchases decreased as food price rose. Cross-price elasticity coefficients were significantly associated with confidence in one’s ability to control weight without smoking (rs = −.23 and .29), but not BMI (rs = .04 and .04) or post-cessation weight concerns (rs = −.05 and .12). Perceived ability to manage weight without cigarettes may influence who substitutes food for cigarettes when quitting. In addition, given observed decreases in purchases of both commodities as food prices increased, these findings imply that greater taxation of fast food-style reinforcers could potentially reduce consumption of these foods and also cigarettes among smokers.

One concern regarding the recent increase in adolescent e-cigarette use is the possibility that electronic (e-) cigarettes may be used by those who might not otherwise have used cigarettes, and that dual use, or transition to cigarette use alone, may follow. Questionnaire data were obtained in 2014 from 11th/12th grade students attending schools in 12 communities included in the Southern California Children's Health Study. We evaluated the cross-sectional association between e-cigarette use, the social environment (family and friends' use and approval of e-cigarettes and cigarettes), and susceptibility to future cigarette use among never cigarette smokers (N = 1,694), using previously validated measures based on reported absence of a definitive commitment not to smoke. Among adolescents who had never used cigarettes, 31.8% of past e-cigarette users and 34.6% of current (past 30-day) e-cigarette users indicated susceptibility to cigarette use, compared with 21.0% of never e-cigarette users. The odds of indicating susceptibility to cigarette use were two times higher for current e-cigarette users compared with never users (odds ratio = 1.97; 95% confidence interval: 1.21-3.22). A social environment favorable to e-cigarettes (friends' use of and positive attitudes toward the use of e-cigarettes) was also associated with greater likelihood of susceptibility to cigarette use, independent of an individual's e-cigarette use. E-cigarette use in adolescence, and a pro-e-cigarette social environment, may put adolescents at risk for future use of cigarettes. E-cigarettes may contribute to subsequent cigarette use via nicotine addiction or social normalization of smoking behaviors. Copyright © 2016 Society for Adolescent Health and Medicine.

This reports the initial phase of a study to quantify the spatial pattern of cigarette butt waste in an urban environment. Geographic Information Systems (GIS) was used to create a weighted overlay analysis model which was then applied to the locations of businesses where cigarettes are sold or are likely to be consumed and venues where higher concentrations of butts may be deposited. The model's utility was tested using a small-scale litter audit in three zip codes of San Diego, California. We found that cigarette butt waste is highly concentrated around businesses where cigarettes are sold or consumed. The mean number of butts for predicted high waste sites was 38.1 (SD 18.87), for predicted low waste sites mean 4.8 (SD 5.9), psales and consumption. A GIS and weighted overlay model may be a useful tool in predicting urban locations of greater and lesser amounts of cigarette butt waste. These data can in turn be used to develop economic cost studies and plan mitigation strategies in urban communities.

Electronic cigarettes (e-cigarettes) are a consumer product whose benefits and risks are currently debated. Advocates of the "tobacco harm reduction" strategy emphasize their potential as an aid to smoking cessation, while advocates of the precautionary principle emphasize their risks instead. There have been only a few studies to date on the prevalence of e-cigarette use in Germany. In May 2016, in collaboration with Forsa, an opinion research firm, we carried out a survey among 4002 randomly chosen persons aged 14 and older, asking them about their consumption of e-cigarettes with and without nicotine, reasons for using e-cigarettes, plans for future use, estimation of danger compared to that of tobacco products, smoking behavior, and sociodemographic features. 1.4% of the respondents used e-cigarettes regularly, and a further 2.2% had used them regularly in the past. 11.8% had at least tried them, including 32.7% of smokers and 2.3% of persons who had never smoked. 24.5% of ex-smokers who had quit smoking after 2010 had used e-cigarettes at least once. 20.7% of the respondents considered electronic cigarettes less dangerous than conventional cigarettes, 46.3% equally dangerous, and 16.1% more dangerous. An extrapolation of these data to the general population suggests that about one million persons in Germany use e-cigarettes regularly and another 1.55 million have done so in the past. The consumption of electronic cigarettes in Germany is not very widespread, but it is not negligible either. Nearly 1 in 8 Germans has tried e-cigarettes at least once. Regular consumers of e-cigarettes are almost exclusively smokers and ex-smokers.

The study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant. Survey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44years from the US. Half (n=400) reported current, daily smoking and half (n=400) reported smoking e-cigarette use were examined using logistic regression. Daily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it was associated with greater impulsivity and illegal drug use. E-cigarette use was associated with hookah use, and for never smokers only with use of cigars and other nicotine products. E-cigarette use among women of reproductive age varies by smoking status, with use among current smokers reflecting attempts to quit smoking whereas among non-smokers use may be a marker of a more impulsive repertoire that includes greater use of alternative tobacco products and illegal drugs.

This article is the first in a series of international case studies developed by the American Cancer Society to illustrate use of publicly available surveillance data for regional tobacco control. A descriptive analysis of Brazil and Paraguay cigarette production and trade data from official sources. Per capita cigarette consumption for Brazil and its neighbour was calculated from 1970 to 1998 using data on production, imports, and exports from NATIONS, the National Tobacco Information Online System. A 63% decrease was observed in the estimate of per capita consumption of cigarettes in Brazil between 1986 and 1998 (from 1913 cigarettes per person in 1986 to 714 cigarettes per person in 1998) and a 16-fold increase in Paraguay was observed during the same period (from 678 cigarettes per person in 1986 to 10 929 cigarettes per person in 1998). Following Brazil's 1999 passage of a 150% cigarette export tax, cigarette exports fell 89% and Brazil's estimated per capita consumption rose to 1990 levels (based on preliminary data). Per capita consumption in Paraguay also fell to 1990 levels. These trends coincide with local evidence that large volumes of cigarettes manufactured in Brazil for export to Paraguay are smuggled back and consumed as tax-free contraband in Brazil. It is hoped that this case study will draw wider public attention to the problems that smuggling presents for tobacco control, help identify other countries confronting similar issues, and stimulate effective interventions.

Cigarette consumption has declined in the USA. However, cigar consumption has increased. This may be due in part to some cigarette smokers switching to filtered cigars as a less expensive substitute for cigarettes. Additionally, some cigarette smokers may perceive and consume little filtered cigars as cigarettes. The purpose of this study was to determine how cigarette smokers classify tobacco products when presented with photographs of those products. An online survey was conducted with a sample of 344 self-identified cigarette smokers. Respondents were presented with pictures of various types of tobacco products, both with and without packaging, and then asked to categorise them as either a cigarette, little cigar, cigarillo, cigar or machine-injected roll-your-own cigarette (RYO). Respondents were also asked about their tobacco use and purchasing behaviour. Overall, respondents had difficulty distinguishing between cigarettes, little cigars, cigarillos and RYO. When presented with images of the products without packaging, 93% of respondents identified RYO as a cigarette, while 42% identified a little cigar as a cigarette. Additionally, respondents stated that they would consider purchasing little cigars as substitutes for cigarettes because of the price advantage. The results of this survey suggest that when presented with photographs of tobacco products, large proportions of current smokers were unable to differentiate between cigarettes, little cigars, cigarillos, RYO and cigars. Findings have implications for existing public health efforts targeting cigarette smokers, and underscore the need to review current definitions of tobacco products and federal excise taxes on such products.

The effect of raising cigarette taxes to reduce smoking has been the subject of several studies, which often treat the price of cigarettes as an exogenous factor given to smokers who respond to it by adjusting their smoking behavior. However, cigarette prices vary with brand and quality, and smokers can and do switch to lower-priced brands to reduce the impact of the tax on the cost of cigarettes as they try to consume the same number of cigarettes as they had before a tax hike. Using data from a two-year follow-up interview survey conducted before and after a new cigarette tax scheme was imposed in Taiwan in 2002, this study examines three behavioral changes smokers may make to respond to tax-induced cigarette price increase: brand-switching, amount consumed, and amount spent on smoking. These changes were studied in relation to smoker income, before-tax cigarette price, level of addiction, exposure to advertizing, and consumer loyalty. We found that smokers, depending upon exposure to advertizing, level of consumer loyalty and initial price of cigarettes, switched brands to maintain current smoking habits and control costs. We also found that the initial amount smoked and level of addiction, not price, at least not at the current levels in Taiwan, determined whether a smoker reduced the number of cigarettes he consumed.

2017-08-01

There is a need to obtain greater clarity regarding adolescents' e-cigarette use and the associations of use with a wider range of risk behaviors. This study examines the associations among past-month e-cigarette use only, traditional cigarette smoking only, dual use (i.e., concurrent e-cigarette use and cigarette smoking), school-related (i.e., truancy and poor academic performance) risk behaviors, and substance-related (i.e., alcohol use, binge drinking, marijuana use, illicit drug use, and nonmedical prescription drug use) risk behaviors. Data were collected via self-administered questionnaires from a nationally representative sample of 8,696 high school seniors. An estimated 9.9% of U.S. high school seniors reported past-month e-cigarette use only, 6.0% reported past-month cigarette smoking only, and 7.3% reported past-month dual use. School- and substance-related risk behaviors had strong associations with past-month e-cigarette use. Adolescents who only used e-cigarettes had significantly greater odds of all school- and substance-related risk behaviors relative to nonusers. Dual users had significantly greater odds of frequent/daily e-cigarette use as well as all school- and substance-related risk behaviors relative to those who only used e-cigarettes. Finally, adolescents who engaged in frequent/daily e-cigarette use had significantly greater odds of binge drinking, marijuana use, other illicit drug use and nonmedical prescription drug use, relative to experimental e-cigarette users. E-cigarette use is common among U.S. adolescents, and there are robust associations between e-cigarette use and school- and substance-related risk behaviors. There is evidence that e-cigarette use clusters with risk behaviors and appears to represent a problem behavior, especially dual use of e-cigarettes and traditional cigarettes.

Introduction To compare hospitalized smokers’ expectancies for electronic cigarettes (e-cigarettes) against their expectancies for tobacco cigarettes and evaluate relationships between e-cigarette expectancies and intention to use e-cigarettes. Methods Analysis of baseline data from a one-year longitudinal observational study. The setting was a tertiary care academic center hospital in the Southeastern U.S. Participants were 958 hospitalized tobacco cigarette smokers. A questionnaire of e-cigarette expectancies based on the Brief Smoking Consequences Questionnaire-Adult (BSCQ-A) was developed and administered along with the original, tobacco-specific, BSCQ-A. Intention to use e-cigarettes was assessed with a single 10-point Likert scale item. Results Participants reported significantly weaker expectancies for e-cigarettes relative to tobacco cigarettes on all 10 BSCQ-A scales. Participants held sizably weaker expectancies for the health risks of e-cigarettes (p < .001, Cohen's d = −2.07) as well as the ability of e-cigarettes to relieve negative affect (p < .001, Cohen's d = −1.01), satisfy the desire for nicotine (p < .001, Cohen's d = −.83), and taste pleasant (p < .001, Cohen's d = −.73). Among the strongest predictors of intention to use e-cigarettes were greater expectancies that e-cigarettes taste pleasant (p < .001, adjusted β = .34), relieve negative affect (p < .001, adjusted β = .32), and satisfy the desire for nicotine (p < .001, adjusted β = .31). Conclusions Hospitalizedtobacco smokers expect fewer negative and positive outcomes from e-cigarettes versus tobacco cigarettes. This suggests that e-cigarettes might be viable though imperfect substitutes for tobacco cigarettes. PMID:25452052

Among adolescents, low socioeconomic status (SES) is associated with greater exposure to tobacco cigarette advertising and cigarette use. However, associations among SES, e-cigarette advertising and e-cigarette use are not well understood. This study examined exposure to e-cigarette advertisements as a mediator of the relationship between SES and adolescent e-cigarette use. Adolescents (N = 3473; 51% Female) from 8 high schools in Connecticut completed an anonymous survey in Spring 2015. Mediation analysis was used to examine whether the total number of sources of recent e-cigarette advertising exposure (e.g., TV, radio, billboards, magazines, local stores [gas stations, convenience stores], vape shops, mall kiosks, tobacco shops, social media) mediated the association between SES (measured by the Family Affluence Scale) and past-month frequency of e-cigarette use. We clustered for school and controlled for other tobacco product use, age, sex, race/ethnicity and perceived social norms for e-cigarette use in the model. Our sample recently had seen advertisements via 2.1 (SD = 2.8) advertising channels. Mediation was supported (indirect effect: β = 0.01, SE = 0.00, 95% CI [0.001, 0.010], p = 0.02), such that higher SES was associated with greater recent advertising exposure, which, in turn, was associated with greater frequency of e-cigarette use. Our study suggests that regulations to reduce youth exposure to e-cigarette advertisement may be especially relevant to higher SES youth. Future research should examine these associations longitudinally and evaluate which types of advertisements target different SES groups. Copyright © 2018 Elsevier Inc. All rights reserved.

Healthy life style and food, beverages and cigarettes consumption in the Czech Republic

Full Text Available In the first part of the article, the authors analyze the term healthy life style. Information sources focusing on health and factors influencing it and having the final impact on it are mostly of medicine character. Together with the development of medicinal diagnostic and curing procedures, the importance of health conditions influenced by infectious diseases is decreasing. On the other hand, the importance of factors related to the life style (eating habits in particular is growing.In the second part of the article, the authors analyze and interpret the data of the Czech Statistical Office about the consumption of selected foods in the form of secondary analysis. The effort was to take into account the assessment of the trends as well as to deduce their possible impact on the health condition of the individual. From the analyses mentioned it is obvious that in the selected statistical data of the development of food and beverages consumption in the Czech Republic the tendencies towards healthy life style have not been unambiguous or significant within the last eight years.In certain areas such as consumption of alcoholic beverages, milk and diary products and meat there have been noted changes for better. In most of the areas analyzed (alcoholic beverages, fruit and vegetable, oil, fish these tendencies are not obvious or significant. Alarming is the growing consumption of cigarettes.

Combustible and smokeless tobacco use causes adverse health outcomes, including cardiovascular disease and multiple types of cancer (1,2). Standard approaches for measuring tobacco use include self-reported surveys of use and consumption estimates based on tobacco excise tax data (3,4). To provide the most recently available tobacco consumption estimates in the United States, CDC used federal excise tax data to estimate total and per capita consumption during 2000-2015 for combustible tobacco (cigarettes, roll-your-own tobacco, pipe tobacco, small cigars, and large cigars) and smokeless tobacco (chewing tobacco and dry snuff). During this period, total combustible tobacco consumption decreased 33.5%, or 43.7% per capita. Although total cigarette consumption decreased 38.7%, cigarettes remained the most commonly used combustible tobacco product. Total noncigarette combustible tobacco (i.e., cigars, roll-your-own, and pipe tobacco) consumption increased 117.1%, or 83.8% per capita during 2000-2015. Total consumption of smokeless tobacco increased 23.1%, or 4.2% per capita. Notably, total cigarette consumption was 267.0 billion cigarettes in 2015 compared with 262.7 billion in 2014. These findings indicate that although cigarette smoking declined overall during 2000-2015, and each year from 2000 to 2014, the number of cigarettes consumed in 2015 was higher than in 2014, and the first time annual cigarette consumption was higher than the previous year since 1973. Moreover, the consumption of other combustible and smokeless tobacco products remains substantial. Implementation of proven tobacco prevention interventions (5) is warranted to further reduce tobacco use in the United States.

Electronic cigarettes (e-cigarettes) are heavily marketed and widely perceived as helpful for quitting or reducing smoking intensity. We test whether ever-use of e-cigarettes among early adopters was associated with: 1) increased cigarette smoking cessation; and 2) reduced cigarette consumption. A representative cohort of U.S. smokers (N = 2454) from the 2010 Tobacco Use Supplement to the Current Population Survey (TUS-CPS) was re-interviewed 1 year later. Outcomes were smoking cessation for 30+ days and change in cigarette consumption at follow-up. E-cigarettes use was categorized as for cessation purposes or for another reason.

Alcohol consumption and cigarette smoking are modifiable lifestyle factors with important impact on public health. It is unclear whether these factors influence the risk of aortic valve stenosis (AVS). To investigate the associations of alcohol consumption and smoking, including smoking intensity and time since cessation, with AVS incidence in two prospective cohorts. This analysis was based on data from the Swedish Mammography Cohort and the Cohort of Swedish Men, comprising 69 365 adults without cardiovascular disease at baseline. Participants were followed for AVS incidence and death by linkage to the Swedish National Patient and Causes of Death Registers. Hazard ratios (HR) with 95% confidence intervals (CI) were estimated by Cox proportional hazards regression. Over a mean follow-up of 15.3 years, 1249 cases of AVS (494 in women and 755 in men) were recorded. Compared with never drinkers of alcohol (lifelong abstainers), the risk of AVS was significantly lower in current light drinkers (1-6 drinks per week [1 drink = 12 g alcohol]; multivariable HR 0.82; 95% CI: 0.68-0.99). The risk of AVS increased with increasing smoking intensity. Compared with never smokers, the HR was 1.46 (95% CI: 1.16-1.85) in current smokers of ≥30 pack-years. Former smokers who had quit smoking 10 or more years previously had similar risk for AVS as never smokers. This study suggests that current light alcohol consumption is associated with a lower risk of AVS, and indicates that the association between smoking and AVS risk is reversible. © 2017 The Authors.

Full Text Available Bradford Hill's viewpoints were used to conduct a weight-of-the-evidence assessment of the association between Parkinson's disease (PD and rural living, farming and pesticide use. The results were compared with an assessment based upon meta-analysis. For comparison, we also evaluated the association between PD and cigarette smoking as a "positive control" because a strong inverse association has been described consistently in the literature.PubMed was searched systematically to identify all published epidemiological studies that evaluated associations between Parkinson's disease (PD and cigarette smoking, rural living, well-water consumption, farming and the use of pesticides, herbicides, insecticides, fungicides or paraquat. Studies were categorized into two study quality groups (Tier 1 or Tier 2; data were abstracted and a forest plot of relative risks (RRs was developed for each risk factor. In addition, when available, RRs were tabulated for more highly exposed individuals compared with the unexposed. Summary RRs for each risk factor were calculated by meta-analysis of Tier 1, Tier 2 and all studies combined, with sensitivity analyses stratified by other study characteristics. Indices of between-study heterogeneity and evidence of reporting bias were assessed. Bradford Hill's viewpoints were used to determine if a causal relationship between PD and each risk factor was supported by the weight of the evidence.There was a consistent inverse (negative association between current cigarette smoking and PD risk. In contrast, associations between PD and rural living, well-water consumption, farming and the use of pesticides, herbicides, insecticides, fungicides or paraquat were less consistent when assessed quantitatively or qualitatively.The weight of the evidence and meta-analysis support the conclusion that there is a causal relationship between PD risk and cigarette smoking, or some unknown factor correlated with cigarette smoking.

Behavioral economic measures of demand provide estimates of tobacco product abuse liability and may predict effects of policy-related price regulation on consumption of existing and emerging tobacco products. In the present study, we examined demand for snus, a smokeless tobacco product, in comparison to both cigarettes and medicinal nicotine. We used both a naturalistic method in which participants purchased these products for use outside the laboratory, as well as laboratory-based self-administration procedures. Cigarette smokers (N = 42) used an experimental income to purchase their usual brand of cigarettes and either snus or gum (only one product available per session) across a range of prices, while receiving all products they purchased from one randomly selected price. In a separate portion of the study, participants self-administered these products during laboratory-based, progressive ratio sessions. Demand elasticity (sensitivity of purchasing to price) was significantly greater for snus than cigarettes. Elasticity for gum was intermediate between snus and cigarettes but was not significantly different than either. Demand intensity (purchasing unconstrained by price) was significantly lower for gum compared to cigarettes, with no significant difference observed between snus and cigarettes. Results of the laboratory-based, progressive ratio sessions were generally discordant with measures of demand elasticity, with significantly higher "breakpoints" for cigarettes compared to gum and no significant differences between other study products. Moreover, breakpoints and product purchasing were generally uncorrelated across tasks. Under naturalistic conditions, snus appears more sensitive to price manipulation than either cigarettes or nicotine gum in existing smokers.

Full Text Available Exhaled aerosols were collected following the use of two leading U.S. commercial electronic cigarettes (e-cigarettes and a conventional cigarette by human subjects and analyzed for phenolics, carbonyls, water, glycerin and nicotine using a vacuum-assisted filter pad capture system. Exhaled breath blanks were determined for each subject prior to each product use and aerosol collection session. Distribution and mass balance of exhaled e-cigarette aerosol composition was greater than 99.9% water and glycerin, and a small amount (<0.06% of nicotine. Total phenolic content in exhaled e-cigarette aerosol was not distinguishable from exhaled breath blanks, while total phenolics in exhaled cigarette smoke were significantly greater than in exhaled e-cigarette aerosol and exhaled breaths, averaging 66 µg/session (range 36 to 117 µg/session. The total carbonyls in exhaled e-cigarette aerosols were also not distinguishable from exhaled breaths or room air blanks. Total carbonyls in exhaled cigarette smoke was significantly greater than in exhaled e-cigarette aerosols, exhaled breath and room air blanks, averaging 242 µg/session (range 136 to 352 µg/session. These results indicate that exhaled e-cigarette aerosol does not increase bystander exposure for phenolics and carbonyls above the levels observed in exhaled breaths of air.

Objective During the past decades, smoking prevalence in Greece was estimated to be near or over 40%. Following a sharp fall in cigarette consumption, as shown in current data, our objective is to assess smokers’ sensitivity to cigarette price and consumer income changes as well as to project health benefits of an additional tax increase. Methods Cigarette consumption was considered as the dependent variable, with Weighted Average Price as a proxy for cigarette price, gross domestic product as a proxy for consumers’ income and dummy variables reflecting smoking restrictions and antismoking campaigns. Values were computed to natural logarithms and regression was performed. Then, four scenarios of tax increase were distinguished in order to calculate potential health benefits. Results Short-run price elasticity is estimated at −0.441 and short-run income elasticity is estimated at 1.040. Antismoking campaigns were found to have a statistically significant impact on consumption. Results indicate that, depending on the level of tax increase, annual per capita consumption could fall by at least 209.83 cigarettes; tax revenue could rise by more than €0.74 billion, while smokers could be reduced by up to 530 568 and at least 465 smoking-related deaths could be averted. Conclusions Price elasticity estimates are similar to previous studies in Greece, while income elasticity estimates are far greater. With cigarettes regarded as a luxury good, a great opportunity is presented for decisionmakers to counter smoking. Increased taxation, along with focused antismoking campaigns, law reinforcement (to ensure compliance with smoking bans) and intensive control for smuggling could invoke a massive blow to the tobacco epidemic in Greece.

To describe the characteristics of two primary determinants of cigarette consumption: cigarette affordability and the range of prices paid for cigarettes (and bidis, where applicable) in a set of 15 countries. From this cross-country comparison, identify places where opportunities may exist for reducing consumption through tax adjustments. Self-response data from 45,838 smokers from 15 countries, obtained from the Global Adult Tobacco Survey (GATS) 2008-2011. Using self-response data on individual cigarette expenditure and consumption, we construct a measure of the average cigarette price smokers pay for manufactured cigarettes (and bidis, where applicable) in 15 countries. We use these prices to evaluate cigarette affordability and the range of prices available in each country. These survey-derived measures of cigarette price and affordability are uniquely suited for cross-country comparison because they represent each country's distinctive mix of individual consumption characteristics such as brand choice, intensity of consumption, and purchasing behavior. In this sample of countries, cigarettes are most affordable in Russia, which has the most room for tobacco tax increase. Affordability is also relatively high in Brazil and China for cigarettes, and in India and Bangladesh for bidis. Although the affordability of cigarettes in India is relatively low, the range of cigarette prices paid is relatively high, providing additional evidence to support the call for simplifying the existing tax structure and reducing the width of price options. China has both high affordability and wide price ranges, suggesting multiple opportunities for reducing consumption through tax adjustments.

Background Iran is one of two main target markets for tobacco smuggling in the WHO's Eastern Mediterranean Region. The Iranian government has a local tobacco monopoly but there is high demand for international brands. Informal reports show about 20% of cigarette consumption is smuggled brands. This pack survey study is the first in Iran to gather validated information on use of smuggled cigarettes. Methods A randomized cross-sectional household survey in Tehran in 2008–2009 of 1540 smokers aged 16–90 (83% men) was performed, including interviewer checking of cigarette packs. Results In all, 20.9% of cigarettes and 6.7% of domestic branded cigarettes were smuggled. A total of 60.1% of smokers preferred foreign cigarettes. There was no significant difference between consumption of illegal cigarettes by sex. (Fisher exact test p=0.61) Use of smuggled cigarettes was higher among younger smokers (p=0.01) Conclusions Use of illegal cigarettes is high. Tobacco control laws outlawing their sale are not being enforced. PMID:20876076

The study attempts to estimate the demand for cigarettes in Tanzania and presents simulation results on the effect of the cigarette excise tax on smoking participation, government revenue, and related topics. After briefly summarizing the magnitude and spread of cigarette consumption in the country, the paper reviews some empirical estimates from African and other countries. The 2008 Tanzanian household budget survey was used to estimate the demand for cigarettes in Tanzania. The descriptive statistics suggest that the smoking prevalence for Tanzania is 15.35 percent with low variability across expenditure (income) groups. Smoking intensity and per capita consumption were estimated at 7.08 cigarettes and 1.33 cigarettes, respectively, a relatively low value. A two-part demand equation model was used to estimate various elasticities. For the overall equation, the price elasticities of smoking participation, smoking intensity, and total elasticity were estimated at -0.879, -0.853, and -1.732, respectively. Compared to similar results in other developing countries, the estimates appear quite high. When estimated by expenditure (income) groups, the magnitude of the elasticity appears higher among high expenditure groups than among low expenditure groups. Two simulation exercises were undertaken. First, the effect of different excise rates on smoking participation rate, cigarette consumption, tax revenue, and related responses was estimated and highlighted. Second, the same exercise was undertaken to determine the effect of a given increase in the cigarette excise tax on various expenditure groups. The overall results suggest that an increase in the excise tax on cigarettes in Tanzania would reduce cigarette consumption and increase government tax revenue.

We investigated the relationship between receptivity to electronic cigarette (e-cigarette) advertisements at baseline and e-cigarette use at follow-up among adult baseline non-users of cigarettes and e-cigarettes. A nationally representative online panel was used to survey non-users of cigarettes and e-cigarettes ( n  = 2191) at baseline and 5-month follow-up. At baseline, respondents were shown an e-cigarette advertisement and asked if they were aware of it (exposure). Among those exposed, receptivity was self-rated for each ad using a validated scale of 1 to 5 for agreement with each of six items: "worth remembering," "grabbed my attention," "powerful," "informative," "meaningful," and "convincing." Logistic regression was used to measure the relationship between receptivity at baseline and e-cigarette use at follow-up. Among baseline non-users of cigarettes and e-cigarettes, 16.6% reported exposure to e-cigarette advertisements at baseline; overall mean receptivity score was 2.77. Among baseline non-users who reported exposure to e-cigarette advertisements, incidence of e-cigarette use at follow-up was 2.7%; among baseline non-users who reported not being exposed to e-cigarette advertisements, incidence of e-cigarette use at follow-up was 1.3%. The attributable risk percentage for e-cigarette initiation from e-cigarette advertisement exposure was 59.3%; the population attributable risk percentage from e-cigarette advertisement exposure was 22.6%. Receptivity at baseline was associated with e-cigarette use at follow-up (aOR = 1.57; 95% CI = 1.04-2.37). Receptivity to e-cigarette advertisements at baseline was associated with greater odds of e-cigarette use at follow-up among baseline non-users of cigarettes and e-cigarettes. Understanding the role of advertising in e-cigarette initiation could help inform public health policy.

How do minimum cigarette price laws affect cigarette prices at the retail level?

Half of US states have minimum cigarette price laws that were originally passed to protect small independent retailers from unfair price competition with larger retailers. These laws prohibit cigarettes from being sold below a minimum price that is set by a formula. Many of these laws allow cigarette company promotional incentives offered to retailers, such as buydowns and master-type programmes, to be calculated into the formula. Allowing this provision has the potential to lower the allowable minimum price. This study assesses whether stores in states with minimum price laws have higher cigarette prices and lower rates of retailer participation in cigarette company promotional incentive programmes. Retail cigarette prices and retailer participation in cigarette company incentive programmes in 2001 were compared in eight states with minimum price laws and seven states without them. New York State had the most stringent minimum price law at the time of the study because it excluded promotional incentive programmes in its price setting formula; cigarette prices in New York were compared to all other states included in the study. Cigarette prices were not significantly different in our sample of US states with and without cigarette minimum price laws. Cigarette prices were significantly higher in New York stores than in the 14 other states combined. Most existing minimum cigarette price laws appear to have little impact on the retail price of cigarettes. This may be because they allow the use of promotional programmes, which are used by manufacturers to reduce cigarette prices. New York's strategy to disallow these types of incentive programmes may result in higher minimum cigarette prices, and should also be explored as a potential policy strategy to control cigarette company marketing practices in stores. Strict cigarette minimum price laws may have the potential to reduce cigarette consumption by decreasing demand through increased cigarette prices and reduced

Do e-cigarettes have the potential to compete with conventional cigarettes?: a survey of conventional cigarette smokers' experiences with e-cigarettes.

Electronic cigarettes (ECs) are becoming increasingly popular globally. If they were to replace conventional cigarettes, it could have a substantial impact on public health. To evaluate EC's potential for competing with conventional cigarettes as a consumer product, we report the first data, to our knowledge, on the proportion of smokers who try ECs and become regular users. A total of 2,012 people seen smoking or buying cigarettes in the Czech Republic were approached to answer questions about smoking, with no mention made of ECs to avoid the common bias in surveys of EC users. During the interview, the volunteers' experience with ECs was then discussed. A total of 1,738 smokers (86%) participated. One-half reported trying ECs at least once. Among those who tried ECs, 18.3% (95% CI, 0.15.7%-20.9%) reported using them regularly, and 14% (95% CI, 11.6%-16.2%) used them daily. On average, regular users used ECs daily for 7.1 months. The most common reason for using ECs was to reduce consumption of conventional cigarettes; 60% of regular EC users reported that ECs helped them to achieve this. Being older and having a more favorable initial experience with ECs explained 19% of the variance in progressing to regular EC use. Almost one-fifth of smokers who try ECs once go on to become regular users. ECs may develop into a genuine competitor to conventional cigarettes. Government agencies preparing to regulate ECs need to ensure that such moves do not create a market monopoly for conventional cigarettes.

Although sport participation among adolescents has been found to lower the risk of traditional cigarette smoking, no studies to date have assessed if this type of physical activity lowers the risk of e-cigarette use among adolescents. National data from the 2014 and 2015 Monitoring the Future study of 12th-grade students were used and analyses were conducted in 2016. Measures for past 30-day e-cigarette use and traditional cigarette smoking were used to assess differences between adolescents who participated in at least one competitive sport during the past year and adolescents who did not. Differences in e-cigarette use and traditional cigarette smoking were assessed between 13 different sports to determine which sports were associated with a greater or lower risk of these behaviors. Adolescents who participated in at least one competitive sport were less likely to engage in past 30-day traditional cigarette smoking (AOR=0.73, 95% CI=0.538, 0.973) and past 30-day dual use of traditional cigarettes and e-cigarettes (AOR=0.66, 95% CI=0.438, 0.982) when compared with their nonparticipating peers. Adolescents who participated in baseball/softball and wrestling were at greatest risk of e-cigarette use. Of the 13 assessed sports, none were found to lower the odds of e-cigarette use. No significant evidence was found that participation in a sport was a protective factor against e-cigarette use. Certain types of athletes are at an elevated risk of e-cigarette use, and prevention efforts targeted at these specific sports should be considered by school administrators.

The major objective of this project is to obtain experimental data that are directly applicable to resolving the question of whether cigarette smokers are at greater risk than nonsmokers to potential health effects of inhaled plutonium. Because cigarette smokers constitute a large fraction of the population, a synergistic effect of plutonium and cigarette smoke might influence estimates of the health risk for plutonium and other transuranics released to the environment

Inadequate self-control has been linked to behavioural and impulse-control problems such as overeating, alcohol and drug abuse and smoking. Construal-level theory (CLT) suggests that a high-level construal (highlighting central goals associated with an event), relative to a low-level construal (highlighting means and resources), promotes self-control. Inspired by CLT, we examined whether smokers primed with a high-level (versus low-level) construal mind-set would show reductions in smoking that might be mediated by improved self-control. A single-factor (construal level: high, low, control) between-subjects design was employed. We used a widely employed why/how paradigm to induce high/low construal levels, whereby participants were asked to respond to questions about 'why' or 'how' they would maintain good physical health. Laboratory at Kaohsiung Medical University, Taiwan. A community sample consisting of 102 daily smokers participated in this experiment. The Stroop task measuring self-control was implemented after the construal-level manipulation. The dependent measure was actual cigarette consumption during an ostensible survey. Participants in a high-level construal mind-set smoked fewer cigarettes [mean = 1.3, 95% confidence interval (CI): 0.9, 1.7] than those in a low-level construal mind-set (mean = 2.6, 95% CI: 2.2, 3.0; P self-control (B = -1.14, 95% CI: -1.65, -0.74, P self-control that leads to reduced cigarette consumption. Thus, reminding smokers to think abstractly about health may be an effective strategy that could help them to smoke fewer cigarettes. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

Full Text Available Electronic cigarettes (e-cigarettes have become increasingly popular at an alarming rate. This coincides with the public perception that they are a safer mean of nicotine consumption. Unregulated devices carry unrecognized safety risks that have led to numerous cases of burns, associating with spontaneous combustions of e-cigarettes.

By 2016, tobacco industry provided the only illicit trade estimates in Colombia and used these to discourage tax increases since the 1990s. To establish the viability of a threefold hike in the excise tax, policy makers needed unbiased estimates of the illicit cigarette. To estimate the size of illicit cigarette trade in five Colombian cities (63% of the market), analyse characteristics of smokers of illicit cigarettes and compare market share results with one industry-funded survey. Street cross-sectional survey with smokers' self-report on consumption pattern, last purchase information and direct observation of smoker's packs. Sampling frame: smokers, men and women, 12 years old or older, all income levels, resident in five Colombian cities (Bogotá, Medellín, Cali, Cartagena and Cúcuta) with 1 733 316 smokers in 2013. Sample size 1697, simple random sample by city, sampling weights based on age groups and cities. Confidence level 95%, margin of error 3.5% for Bogotá and Medellín and 5% for the other three cities. Data collection period: 24 August-14 September 2016. Illicit cigarettes represent 3.5% of consumption in the five cities, a much lower estimate than the industry data. There are significant differences across cities, with Bogotá at the bottom (1.5%) and Cúcuta at the top (22.8%). The low overall penetration of illicit cigarettes in Colombia indicates that the industry's warnings against tax increases are not justified. The limited importance of tax levels as determinant of consumption of illicit cigarettes is also suggested by the differences across cities, all of them with the same tax regime. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Electronic cigarettes (e-cigarettes) are popular alternatives to conventional cigarettes among adult smokers wishing to reduce their exposure to harmful smoke constituents. However, little information exists on the relative internal exposures resulting from the exclusive or dual use of e-cigarettes. Measurements of product use; adverse events; changes in smoking urge; and blood, urine and exhaled breath biomarkers of exposure (BoE) representing toxicants believed to contribute to smoking related diseases were made at baseline and after five days of product use in 105 clinically-confined smokers randomized into groups that partially or completely substituted their usual brand combustible cigarette with commercial e-cigarettes, or discontinued all nicotine and tobacco products.

To assess the impact of a reduction in the nicotine content of cigarettes on estimated consumption of reduced nicotine cigarettes and usual brand cigarettes at a variety of hypothetical prices. Double-blind study with participants assigned randomly to receive cigarettes for 6 weeks that were either usual brand or an investigational cigarette with one of five nicotine contents. Ten sites across the United States. A total of 839 eligible adult smokers randomized from 2013 to 2014. Participants received their usual brand or an investigational cigarette with one of five nicotine contents: 15.8 (primary control), 5.2, 2.4, 1.3, or 0.4 mg/g. The Cigarette Purchase Task was completed at baseline and at the week 6 post-randomization visit. Compared with normal nicotine content controls, the lowest nicotine content (0.4 mg/g) reduced the number of study cigarettes participants estimated they would smoke at a range of prices [mean reduction relative to 15.8 mg/g at a price of $4.00/pack: 9.50, 95% confidence interval (CI) = 6.81,12.19]. The lowest nicotine content also reduced the maximum amount of money allocated to study cigarettes and the price at which participants reported they would stop buying study cigarettes [median reduction relative to 15.8 mg/g, 95% CI = $8.21 (4.27,12.15) per day and $0.44 (0.17,0.71) per cigarette, respectively]. A reduction in nicotine content to the lowest level also reduced the maximum amount of money allocated to usual brand cigarettes (median reduction relative to 15.8 mg/g: $4.39 per day, 95% CI = 1.88,6.90). In current smokers, a reduction in nicotine content may reduce cigarette consumption, reduce the reinforcement value of cigarettes and increase cessation if reduced nicotine content cigarettes were the only cigarette available for purchase. © 2016 Society for the Study of Addiction.

Changes in cigarette expenditure minimising strategies before and after a cigarette tax increase.

Choi, Kelvin; Boyle, Raymond G

Smokers use cigarette expenditure minimising strategies (CEMS) to alleviate the effect of tax increases on their cigarette expenses. We examined changes in smokers' CEMS use before and after a 2013 Minnesota $1.75 cigarette tax increase. Data were from representative samples of smokers who participated in the Minnesota Adult Tobacco Survey 2010 (n=948) and 2014 (n=1229). Participants indicated CEMS used in the past year from a list. Weighted multiple logistic regressions were used to examine changes in prevalence of each CEMS use over time adjusting for demographics and cigarette consumption. Characteristics associated with CEMS use in 2014 were examined. Between 2010 and 2014, more smokers tried to save money on cigarettes by rolling their own cigarettes (from 19% to 29%), using other tobacco products (from 13% to 25%), and buying cigarettes from cheaper places (from 48% to 55%). Yet, fewer smokers used coupons/promotions (from 63% to 50%) and bought cigarettes by the carton (from 39% to 32%). These changes varied somewhat by race/ethnicity and education, for example, more smokers with tax increase. Regulations that would reduce CEMS use could boost the effectiveness of cigarette tax increases. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Do increases in cigarette prices lead to increases in sales of cigarettes with high tar and nicotine yields?

Science.gov (United States)

Farrelly, Matthew C; Loomis, Brett R; Mann, Nathan H

2007-10-01

We used scanner data on cigarette prices and sales collected from supermarkets across the United States from 1994 to 2004 to test the hypothesis that cigarette prices are positively correlated with sales of cigarettes with higher tar and nicotine content. During this period the average inflation-adjusted price for menthol cigarettes increased 55.8%. Price elasticities from multivariate regression models suggest that this price increase led to an increase of 1.73% in sales-weighted average tar yields and a 1.28% increase in sales-weighted average nicotine yields for menthol cigarettes. The 50.5% price increase of nonmenthol varieties over the same period yielded an estimated increase of 1% in tar per cigarette but no statistically significant increase in nicotine yields. An ordered probit model of the impact of cigarette prices on cigarette strength (ultra-light, light, full flavor, unfiltered) offers an explanation: As cigarette prices increase, the probability that stronger cigarette types will be sold increases. This effect is larger for menthol than for nonmenthol cigarettes. Our results are consistent with earlier population-based cross-sectional and longitudinal studies showing that higher cigarette prices and taxes are associated with increasing consumption of higher-yield cigarettes by smokers.

Implications of raising cigarette excise taxes in Peru

Directory of Open Access Journals (Sweden)

Martin Gonzalez-Rozada

Full Text Available ABSTRACT Objective To assess how raising cigarette excise taxes in Peru might impact cigarette consumption, and to determine if higher taxes would be regressive. Methods Total demand price elasticity was estimated by income groups using two datasets: quarterly time-series data from 1993 – 2012 and data from a cross-sectional survey of income and expenses conducted in 2008 – 2009 . A functional form of the cigarette demand in Peru was specified using the quarterly data set, and the demand price elasticity was estimated for the short and long run. Using the second data set and Deaton methodology, the implementation of elasticity estimation and by groups’ elasticity was done in a two-step procedure. Results Demand price elasticity was −0.7, implying that a 10% price increase via a new tax would reduce consumption by 7%. Demand price elasticity estimations by income group suggested that poorer families are not more price sensitive than richer ones, which implies that increasing cigarette taxes could be regressive. Conclusions Increasing cigarette taxes is the most efficient policy for inducing a reduction in smoking. However, in the case of Peru, an increase in cigarette taxes could be regressive.

The carcinogenic effect of 210 Po and 210 Pb with respect to lung cancer is an important problem in many countries with very high cigarette consumption. Poland has one of the highest consumptions of cigarettes in the world. The results of 210 Po determination on the 14 most frequently smoked brands of cigarettes which constitute over 70% of the total cigarette consumption in Poland are presented and discussed. Moreover, the polonium content in cigarette smoke was estimated on the basis of its activity in fresh tobaccos, ash, fresh filters and post-smoking filters. The annual effective doses were calculated on the basis of 210 Po and 210 Pb inhalation with the cigarette smoke. The results of this work indicate that Polish smokers who smoke one pack (20 cigarettes) per day inhale from 20 to 215 mBq of 210 Po and 210 Pb each. The mean values of the annual effective dose for smokers were estimated to be 35 and 70 μSv from 210 Po and 210 Pb, respectively. For persons who smoke two packs of cigarettes with higher radionuclide concentrations, the effective dose is much higher (471 μSv yr -1 ) in comparison with the intake in diet. Therefore, cigarettes and the absorption through the respiratory system are the main sources and the principal pathway of 210 Po and 210 Pb intake of smokers in Poland

Drug Metabolizing Enzyme and Transporter Gene Variation, Nicotine Metabolism, Prospective Abstinence, and Cigarette Consumption.

Full Text Available The Nicotine Metabolite Ratio (NMR, ratio of trans-3'-hydroxycotinine and cotinine, has previously been associated with CYP2A6 activity, response to smoking cessation treatments, and cigarette consumption. We searched for drug metabolizing enzyme and transporter (DMET gene variation associated with the NMR and prospective abstinence in 2,946 participants of laboratory studies of nicotine metabolism and of clinical trials of smoking cessation therapies. Stage I was a meta-analysis of the association of 507 common single nucleotide polymorphisms (SNPs at 173 DMET genes with the NMR in 449 participants of two laboratory studies. Nominally significant associations were identified in ten genes after adjustment for intragenic SNPs; CYP2A6 and two CYP2A6 SNPs attained experiment-wide significance adjusted for correlated SNPs (CYP2A6 PACT=4.1E-7, rs4803381 PACT=4.5E-5, rs1137115, PACT=1.2E-3. Stage II was mega-regression analyses of 10 DMET SNPs with pretreatment NMR and prospective abstinence in up to 2,497 participants from eight trials. rs4803381 and rs1137115 SNPs were associated with pretreatment NMR at genome-wide significance. In post-hoc analyses of CYP2A6 SNPs, we observed nominally significant association with: abstinence in one pharmacotherapy arm; cigarette consumption among all trial participants; and lung cancer in four case:control studies. CYP2A6 minor alleles were associated with reduced NMR, CPD, and lung cancer risk. We confirmed the major role that CYP2A6 plays in nicotine metabolism, and made novel findings with respect to genome-wide significance and associations with CPD, abstinence and lung cancer risk. Additional multivariate analyses with patient variables and genetic modeling will improve prediction of nicotine metabolism, disease risk and smoking cessation treatment prognosis.

Amato, Michael S; D'Silva, Joanne; Boyle, Raymond G

2016-05-01

The proportion of smokers who use menthol cigarettes has increased nationally since 2004, while use of non-menthol cigarettes is declining, suggesting that menthol may be undermining the effectiveness of population level tobacco control efforts. In 2013 Minnesota passed a $1.75 cigarette tax increase. We investigated whether sales of menthol and non-menthol cigarettes were differentially affected by the price increase. Cigarette sales data from convenience stores in the Minneapolis, Minnesota, metro area from January 2012, through May 2015, were obtained. Proportion of sales accounted for by menthol cigarettes was analyzed with segmented regression. Before the price increase, menthol cigarettes gained 2.21% (1.17, 3.12) of market share annually. Following the price increase, the trend slowed to 0.26% (-0.78, 1.56) annually. The slope before the price increase was significantly positive; the slope following the price increase did not significantly differ from zero. Sales of menthol cigarettes declined less rapidly than non-menthol cigarettes before the price increase. Sales of menthol and non-menthol cigarettes declined at more comparable rates after the price increase. Increasing the price of tobacco may help ensure declines in consumption are more evenly distributed across menthol and non-menthol cigarettes. Using sales data, we found that a trend of increasing market share for menthol cigarettes was significantly reduced by a $1.75 cigarette price increase. These results suggest that cigarette price increases, a core tobacco control policy, may have a greater effect on menthol smokers than non-menthol smokers. © The Author 2015.

Greece is in an economic crisis compounded by the costs caused by smoking. The present investigation estimates the economic and public health benefits ensuing from the recent cigarette excise tax increase in 2011 and projects the potential benefits from an additional €2.00 per pack cigarette tax increase. The effects of the recent cigarette excise tax increase were calculated on outcome measures: total price per pack, including specific excise, ad valorem tax, and value-added tax consumption; tax revenue; and per capita consumption of cigarettes. Additionally, smoking-attributable mortality, years of potential life lost, and productivity losses were estimated. Projected effects of an additional €2.00 per pack tax increase on consumption and tax revenue were also assessed. The cigarette excise tax increase in 2011 created €558 million in new tax revenue. Cigarette consumption reached a recent low of 24.9 billion sticks sold or 2197 sticks per person in 2011, indicating a 16% decrease in per capita cigarette consumption from the previous year. An additional €2.00 per pack increase in Greek cigarette taxes is projected to result in reduced cigarette sales by an additional 20% and lead to an increase in total cigarette tax revenues by nearly €1.2 billion and the prevention of 192,000 premature deaths. Nations such as Greece, should employ taxation as a crucial measure to promote public health and economic development in such dire times. International economic organisations should aggressively pursue programmes and policies that champion the economic benefits of tobacco taxation. Published by the BMJ Publishing Group Limited.

Full Text Available Abstract Background Little is known about electronic cigarette (e-cigarette use among Chinese adolescents. We examined the prevalence of current (past 30-day e-cigarette use and its associated factors in a large sample of adolescents in Hong Kong. Methods We analyzed data of the School-based Survey on Smoking among Students 2012/13 from a representative sample of 45,857 secondary school students (mean age: 14.8 ± 1.9. We conducted chi-square tests and t-test to compare current e-cigarette use by covariates. We used multivariable logistic regression to examine the association between current e-cigarette use and demographic variables, parental smoking, peer smoking, knowledge about the harm of cigarette smoking, attitudes toward cigarette smoking, cigarette smoking status, use of other tobacco products, and alcohol consumption. Results Overall, 1.1 % of students reported current e-cigarette use. Of e-cigarette users, 11.7 % were never-cigarette smokers, 15.8 % were experimental cigarette smokers, 39.3 % were former cigarette smokers, and 33.2 % were current cigarette smokers. Current e-cigarette use was associated with male sex, poor knowledge about the harm of smoking, cigarette smoking, use of other tobacco products, and alcohol consumption. Conclusions Surveillance and intervention efforts should address a wide range of tobacco products, including e-cigarettes. Tobacco cessation programs should also address alcohol use collectively. Policies prohibiting e-cigarette sales to minors may help prevent e-cigarette uptake among adolescents.

Taxation, smuggling and demand for cigarettes in Canada: evidence from time-series data.

Galbraith, J W; Kaiserman, M

1997-06-01

This study analyzes Canadian cigarette consumption and taxation between 1980 and 1994, a period in which there have been large price rises and declines, and a dramatic increase in the consumption of contraband tobacco products. We examine elasticities of legal cigarette sales and total sales (including contraband) with respect to the price of legal cigarettes and various other factors. The growth of the contraband market since 1987 appears to have created two classes of cigarette--taxed and untaxed--with responses to changes in the legal price that are respectively higher, and lower, than was previously the case. The sensitivity of total cigarette sales to the taxation instrument is much lower than it would appear from sales of taxed cigarettes alone.

Consumption and production waste: another externality of tobacco use.

To describe the waste produced by and environmental implications of individual cigarette consumption (filter tips, packages, and cartons) and tobacco manufacturing. All available articles and reports published since 1970 related to cigarette consumption and production waste were reviewed. Global cigarette consumption data were used to estimate cigarette butt and packaging waste quantities. Data from the Center for Marine Conservation's International Coastal Cleanup Project were used to describe some environmental impacts of tobacco-related trash. Data from the United States Environmental Protection Agency's (EPA's) Toxics Release Inventory and reported global cigarette consumption totals were used to estimate waste production from cigarette manufacturing. In 1995, an estimated 5.535 trillion cigarettes (27,675 million cartons and 276,753 million packages) were sold by the tobacco industry globally. Some of the wastes from these products were properly deposited, but a large amount of tobacco consumption waste ends up in the environment. Some is recovered during environmental clean-up days. For the past eight years (1990-1997), cigarette butts have been the leading item found during the International Coastal Cleanup Project; they accounted for 19.1% of all items collected in 1997. The tobacco manufacturing process produces liquid, solid, and airborne waste. Among those wastes, some materials, including nicotine, are designated by the EPA as Toxics Release Inventory (TRI) chemicals. These are possible environmental health hazards. In 1995, the global tobacco industry produced an estimated 2262 million kilograms of manufacturing waste and 209 million kilograms of chemical waste. In addition, total nicotine waste produced in the manufacture of reduced nicotine cigarettes was estimated at 300 million kilograms. Laws against littering relative to cigarette butts could be better enforced. Additional taxes might be levied on cigarette products that would then be directed to

Inhaling habits among smokers of different types of cigarette

Energy Technology Data Exchange (ETDEWEB)

Wald, N.J.; Idle, M.; Boreham, J.; Bailey, A.

1980-12-01

Inhaling habits were studied in 1316 men who freely smoked their usual brands of cigarette. An index of inhaling was calculated for each person by dividing the estimated increase in carboxyhaemoglobin level from a standard number of cigarettes by the carbon monoxide yield of the cigarette smoked. Smokers of ventilated filter cigarettes inhaled 82% more than smokers of plain cigarettes (p less than 0.001) and those who smoked unventilated filter cigarettes inhaled 36% more (p less than 0.001). Cigarette consumption was similar among smokers of each type of cigarette. Assuming that the intake of tar and nicotine is proportional to the inhaling index, the intake in either group of filter cigarette smokers would have been less than that in plain cigarette smokers. Among smokers of unventilated cigarettes, however, the intake would not have been much less.

This study examined the effect of two e-cigarette warning labels on college students' perceived advantages and risks of e-cigarette use, as well as students' intentions to use e-cigarettes. The company-produced e-cigarette warning label carries abundant information with small font size while the governmental warning label has only two sentences presented in large font size. The effect of both labels have not yet been examined and verified. Data were collected in October 2015 from college students at a Midwestern university. A pretest-posttest design was employed with 338 students exposed to the warning label proposed by the FDA and 328 students exposed to the label created by e-cigarette companies. Structural equation modeling analysis was implemented to examine the effect of warning labels with the analytical model grounded in the Theory of Planned Behavior. Findings showed that college students' perceived advantages of e-cigarette use were positively related to their intentions to use e-cigarettes, while perceived risks were negatively associated with their intentions. When comparing two labels, the governmental label was found to reduce college students' intentions to use e-cigarettes via increasing perceived risks of e-cigarette use (β=0.10, pe-cigarette use. The warning label currently used by e-cigarette companies showed no influence on beliefs about or intentions to use e-cigarettes. The warning label proposed by the FDA is more effective than that created by e-cigarette companies, however, has room for improvement to make a greater impact on e-cigarette use intention.

Impact of cigarette minimum price laws on the retail price of cigarettes in the USA.

Science.gov (United States)

Tynan, Michael A; Ribisl, Kurt M; Loomis, Brett R

2013-05-01

Cigarette price increases prevent youth initiation, reduce cigarette consumption and increase the number of smokers who quit. Cigarette minimum price laws (MPLs), which typically require cigarette wholesalers and retailers to charge a minimum percentage mark-up for cigarette sales, have been identified as an intervention that can potentially increase cigarette prices. 24 states and the District of Columbia have cigarette MPLs. Using data extracted from SCANTRACK retail scanner data from the Nielsen company, average cigarette prices were calculated for designated market areas in states with and without MPLs in three retail channels: grocery stores, drug stores and convenience stores. Regression models were estimated using the average cigarette pack price in each designated market area and calendar quarter in 2009 as the outcome variable. The average difference in cigarette pack prices are 46 cents in the grocery channel, 29 cents in the drug channel and 13 cents in the convenience channel, with prices being lower in states with MPLs for all three channels. The findings that MPLs do not raise cigarette prices could be the result of a lack of compliance and enforcement by the state or could be attributed to the minimum state mark-up being lower than the free-market mark-up for cigarettes. Rather than require a minimum mark-up, which can be nullified by promotional incentives and discounts, states and countries could strengthen MPLs by setting a simple 'floor price' that is the true minimum price for all cigarettes or could prohibit discounts to consumers and retailers.

Recent studies have shown that more opportunities exist for tax avoidance when cigarette excise tax structure departs from a uniform specific structure. However, the association between tax structure and cigarette price variability has not been thoroughly studied in the existing literature. To examine how cigarette tax structure is associated with price variability. The variability of self-reported prices is measured using the ratios of differences between higher and lower prices to the median price such as the IQR-to-median ratio. We used survey data taken from the International Tobacco Control Policy Evaluation (ITC) Project in 17 countries to conduct the analysis. Cigarette prices were derived using individual purchase information and aggregated to price variability measures for each surveyed country and wave. The effect of tax structures on price variability was estimated using Generalised Estimating Equations after adjusting for year and country attributes. Our study provides empirical evidence of a relationship between tax structure and cigarette price variability. We find that, compared to the specific uniform tax structure, mixed uniform and tiered (specific, ad valorem or mixed) structures are associated with greater price variability (p≤0.01). Moreover, while a greater share of the specific component in total excise taxes is associated with lower price variability (p≤0.05), a tiered tax structure is associated with greater price variability (p≤0.01). The results suggest that a uniform and specific tax structure is the most effective tax structure for reducing tobacco consumption and prevalence by limiting price variability and decreasing opportunities for tax avoidance.

Cigar and e-cigarette use is becoming increasingly common among US tobacco users and the Food and Drug Administration recently asserted regulatory jurisdiction over these products, among others, in May 2016. Research on tobacco dependence among users of these products is limited, however. We therefore examined several symptoms of dependence and cessation intentions among adult cigarette, cigar, and/or e-cigarette users in a nationally representative sample. We used nationally representative data from more than 60,000 participants in the US National Adult Tobacco Survey (NATS) from 2012 to 2013 to analyze dependence symptoms and cessation intentions for users of cigarettes, cigars, and/or e-cigarettes but not other tobacco products. Among daily tobacco users, dual cigarette and cigar users on average smoked more cigarettes per day (17.3, 95 % CI = 16.1, 18.6 vs. 15.8, 95 % CI = 15.4, 16.2), had shorter times to first tobacco use after waking (21.4 min, 95 % CI = 16.6, 24.9 vs. 25.9 min, 95 % CI = 25.3, 26.5), and were more likely to report withdrawal and craving symptoms than exclusive cigarette smokers. Dual cigarette and e-cigarette users were more likely than exclusive cigarette smokers to report withdrawal and craving symptoms and cessation intentions. Exclusive cigar and e-cigarette users were less likely to report withdrawal and craving symptoms than users of other products, but even so, more than a third of exclusive cigar (38.8 %, 95 % CI = 27.4 %, 51.6 %) and e-cigarette (46.1 %, 95 % CI = 35.1 %, 57.4 %) users reported experiencing a strong craving for a tobacco product in the past 30 days. Dual cigarette and cigar users show evidence of greater dependence symptoms and dual cigarette and e-cigarette users show evidence of greater dependence symptoms and cessation intentions compared with exclusive cigarette smokers. A sizeable number of users of all of the tobacco products report dependence symptoms such as craving for

Background There are few studies that examine the impact of tobacco tax and price policies in China. In addition, very little is known about the differential responses to tax and price increases based on socioeconomic status in China. Objective The goal of this study is to estimate the conditional cigarette consumption price elasticity among adult urban smokers in China using individual level longitudinal survey data. We also examine the differential responses to cigarette price increases among groups with different income and/or educational levels. Methods Multivariate analyses using the general estimating equations (GEE) method were conducted to estimate the conditional cigarette demand price elasticity using data from the International Tobacco Control (ITC) China Survey, a longitudinal survey of adult smokers in seven cities in China. The first three waves of the ITC China Survey data were used in this analysis. Analyses based on subsample by education and income were conducted. Findings Our results show that overall conditional cigarette demand price elasticity ranges from −0.12 to −0.14, implying a 10% increase in cigarette price would result in a reduction in cigarette consumption among adult urban Chinese smokers by 1.2% to 1.4%. No differential responses to cigarette price increase were found across education levels. The price elasticity estimates do not differ between high income smokers and medium income smokers. However, cigarette consumption among low income smokers did not seem to decrease after a price increase, at least among those who continued to smoke. Conclusion Relative to many other low- and middle-income countries, cigarette consumption among Chinese adult smokers is not very sensitive to changes in cigarette prices. The total impact of cigarette price increase would be larger if its impact on smoking initiation and cessation, as well as the price-reducing behaviors such as brand switching and trading down, were taken into account.

Paramedical personnel are exposed to tobacco smoking. Electronic cigarettes (e-cigarettes) may be considered as a lower-risk substitute for cigarettes. The aim of the study was to estimate the prevalence of e-cigarette use, the motives for use and the perceptions among French military nurses. A cross-sectional survey, using self-administered questionnaires, was conducted in 2013 among 300 students and instructors of the French school of military paramedical personnel. Prevalences of e-cigarette use among smokers and nonsmokers were compared using logistic regressions adjusted on age and gender. The prevalence of smoking was 40% among the 200 responders. E-cigarette current use prevalence was 25% (6% daily users), without significant difference according to gender and age. Tobacco smokers reported significantly more e-cigarette current use (51% vs7%). Motives for e-cigarette use reported by smokers were curiosity (48%), intention to reduce tobacco consumption (43%) or to quit smoking (8%). Among users of both tobacco and e-cigarettes, 48% reported a significant decrease in tobacco consumption following e-cigarette initiation (average decrease of 5-10 cigarettes smoked per day; p <0.001). Both tobacco smokers and nonsmokers (88%) estimated that e-cigarette use was potentially harmful for health, but it was perceived as less harmful than tobacco by 46%. E-cigarette use among military nurses follows the trends observed in the general population in terms of prevalence and motives. E-cigarettes, which are seen as an attractive alternative to cigarettes, may contribute to a reduction in tobacco use among healthcare workers.

Full Text Available Background Uruguay has implemented strong tobacco control policies over the years which has resulted in decreased tobacco consumption. However, there is little information about flavored cigarettes and on electronic cigarettes (ECs. EC sales are banned in Uruguay. The purpose of this study is to evaluate consumption of these products. Methods Data is from the International Tobacco Control (ITC Uruguay Wave 5 smokers aged 18 and older in five cities. The sample size was 1,428 smokers. Results The minimum age of onset of smoking was 5 years old and 96% of smokers started smoking before the age of 25. Two out of three (68.6% smokers chose their cigarette brand because of the taste. 72.5% have tried flavored (menthol cigarettes, and1.3% currently smoking menthol brands. Younger age (94% aged 18-24 and smokers with higher education (84% high, 74% medium, 61% low have tried menthol cigarettes associated with. Awareness of ECs was 56% among the smokers, but it is higher among smokers aged 18-24 (62% and smokers with higher education (81%. Among the smokers who had heard of e-cigarettes. 12.8% had tried once (higher under age 24 (24% and higher among smokers with high education level (20%. Among the smokers, 1.3% using EC daily and 1.9% using EC weekly. Conclusions Taste is a very important factor for Uruguayan smokers. Almost all young smokers have tried menthol cigarettes. ECs use is also on the rise, mainly among young peopleand people with higher education. There is a need for monitoring flavored cigarettes and EC consumptionto defining new regulations for them.

We determined the prevalence and correlates of other tobacco product and electronic cigarette (e-cigarette) use in a clinic-based sample of homeless cigarette smokers. In April-July 2014, we used time-location sampling to conduct a cross-sectional, in-person survey of 306 currently homeless adult cigarette smokers recruited from 5 clinical sites at Boston Health Care for the Homeless Program. We assessed past-month use of large cigars, little cigars, smokeless tobacco, and e-cigarettes. Among those who had used e-cigarettes, we assessed the reasons for doing so. We used logistic regression analysis to identify the participant characteristics associated with the use of each product. Eighty-six percent of eligible individuals participated in the survey. In the past month, 37% of respondents used large cigars, 44% used little cigars, 8% used smokeless tobacco, 24% used an e-cigarette, and 68% used any of these products. Reasons for e-cigarette use included curiosity (85%) and to help quit conventional cigarettes (69%). In multivariable regression analyses, homeless smokers with greater subsistence difficulties were more likely to use little cigars (p=0.01) and less likely to use e-cigarettes (p=0.001). Non-Hispanic black (p=0.01), Hispanic (pcigars. Readiness to quit was not associated with other tobacco product use but was significantly associated with e-cigarette use to help quit smoking (p=0.02). Health care providers who serve homeless people should consider routine screening for the use of other tobacco products and e-cigarettes to help guide smoking cessation discussions and tobacco treatment planning.

Expectancies demonstrate cross-sectional associations with e-cigarette use, but the prospective relationships between expectancies and e-cigarette use are unknown. This study examined the longitudinal associations of expectancies with e-cigarette use among hospitalized tobacco cigarette smokers. E-cigarette expectancies (e-cigarette-specific Brief Smoking Consequences Questionnaire-Adult [BSCQ-A]), tobacco cigarette expectancies (tobacco-specific BSCQ-A), and number of days used e-cigarettes in the past 30 days were assessed at baseline hospitalization, 6-months post-hospitalization, and 12-months post-hospitalization among 978 hospitalized tobacco cigarette smokers. Expectancy difference scores (e-cigarette-specific expectancies minus tobacco-specific expectancies) were computed for each of the 10 BSCQ-A scales. Cross-lagged panel models tested the relationships between expectancy difference scores and number of days used e-cigarettes in the past 30 days for each of the 10 BSCQ-A scales. Though some models revealed partial associations between expectancies and e-cigarette use, only one yielded results consistent with hypotheses. Greater e-cigarette use at baseline predicted greater expectancies that e-cigarettes taste pleasant as compared to tobacco cigarettes at 6 months, which then predicted greater e-cigarette use at 12 months. To a lesser degree greater expectancies that e-cigarettes taste pleasant as compared to tobacco cigarettes at baseline predicted greater e-cigarette use at 6 months, which then predicted greater expectancies that e-cigarettes taste pleasant as compared to tobacco cigarettes at 12 months. Expectancies that e-cigarettes provide similar or more pleasant taste sensations as compared to tobacco cigarettes may be both a cause and consequence of e-cigarette use. Focusing on the taste experience may prove most effective in modifying e-cigarette use behavior. The current study offers the first longitudinal examination of expectancies and e-cigarette

High-sensitivity C-reactive protein (hsCRP) is possibly related to osteoarthritis (OA) progression and a variety of OA-related symptoms. This study aimed to examine associations between cigarette smoking, betel quid chewing and alcohol consumption and hsCRP in early radiographic knee OA. Cross-sectional health examination survey. This primary study was conducted in a health examination centre in China. 936 (656 men and 280 women) patients with early radiographic knee OA were included in this cross-sectional study. Smoking status was classified into four levels based on daily smoking habit: 0/day, 1-10/day, 11-20/day and >20/day. Betel quid chewing and alcohol consumption status was divided into 'Yes' or 'No'. Early radiographic knee OA was defined as Kellgren Lawrence (K-L) grade 1 or 2 in at least one leg, and elevated hsCRP was assessed as ≥ 3.0 mg/L. After adjustment for a number of potential confounding factors, a significant positive association between cigarette smoking and hsCRP was observed in the multivariable model. The multivariable-adjusted ORs (95% CI) of elevated hsCRP (≥ 3.0 mg/L) in the second (1-10/day, n=133), third (11-20/day, n=59) and highest (>20/day, n=104) cigarette smoking categories were 1.54 (95% CI 0.91 to 2.61), 1.27 (95% CI 0.57 to 2.79) and 2.09 (95% CI 1.20 to 3.64), respectively, compared with the non-smoker category (n=640). In addition, there was a positive dose-response relationship between cigarette smoking and elevated hsCRP (p for trend=0.01). No significant associations between betel quid chewing and alcohol consumption and hsCRP were observed in the multivariable model. This study indicated that cigarette smoking was positively associated with serum hsCRP level in patients with early radiographic knee OA. However, in view of the nature of cross-sectional designs, the results need to be confirmed by further prospective studies. Published by the BMJ Publishing Group Limited.

Full Text Available Baking treatment is one of the most important processes of cigarette production, which can significantly enhance quality of tobacco. Theoretical and numerical investigation on temperature distribution in a cigarette oven during baking was carried out. The finite volume method was used to simulate the flow field. The relationship between the uniformity of temperature field and impeller’s speed was given finally, which is helpful to optimize cigarette oven with better quality and less energy consumption.

Cigarette smuggling in Europe: who really benefits?

Science.gov (United States)

Joossens, L; Raw, M

1998-01-01

Cigarette smuggling, now on the increase, is so widespread and well organised that it poses a serious threat to public health. This threat comes from two principal directions. First, smuggling makes cigarettes available cheaply, thereby increasing consumption. A third of annual global exports go to the contraband market, representing an enormous impact on consumption, and thus causing an increase in the burden of disease, especially in poorer countries. It is also costing government treasuries thousands of millions of dollars in lost tax revenue. Second, the tobacco industry uses smuggling politically, lobbying governments to lower tax, arguing that smuggling is caused by price differences. This paper shows that the claimed correlation between high prices and high levels of smuggling does not exist in western Europe. In fact, countries such as Norway and Sweden, with expensive cigarettes, do not have a large smuggling problem, whereas countries in the south of Europe do. Cigarette smuggling is not caused principally by "market forces". It is mainly caused by fraud, by the illegal evasion of import duty. The cigarettes involved are not the cheap brands from southern European countries, for which there is no international market. It is the well-known international brands such as Marlboro and Winston. We propose much tighter regulation of cigarette trade, including an international transport convention, and a total ban on transit trade-sale by the manufacturers to dealers, who sell on to smugglers.

Although existing evidence indicates that e-cigarette use is a risk factor for cigarette smoking initiation, mechanisms of this association are not yet known. E-cigarette users perceive e-cigarette use to be less harmful relative to conventional cigarettes, but their absolute perceptions of addictiveness of conventional cigarette smoking are unknown. This study examines how e-cigarette users compare with nonusers (non-e-cigarette users/nonconventional cigarette smokers), conventional cigarette smokers, and dual users on perceptions of harm and the addictiveness of conventional cigarette smoking and on other known predictors of cigarette smoking such as peer smoking, influence of antismoking ads, and risk-taking propensity. National samples of 8th- and 10th-grade students from 2014 and 2015 (N = 14,151) were obtained from the Monitoring the Future Study. Multivariate logistic regression models were used to examine relationships between adolescent smoking status and perceptions of harm and the addictiveness of conventional cigarette smoking while controlling for potential confounders. E-cigarette users had lower perceptions of the addictiveness of conventional cigarette smoking compared with nonusers but higher than cigarette smokers and dual users. E-cigarette users reported lower influence by antismoking ads, more conventional cigarette-smoking peers, and greater risk-taking propensity than nonusers. E-cigarette users and cigarette smokers did not differ in their perceived harm of conventional cigarette smoking or in their risk-taking propensity. E-cigarette users' attitudes and perceptions regarding conventional cigarette smoking may leave them vulnerable to becoming conventional cigarette smokers. Future studies should explore the prospective relationship between smoking-related perceptions of conventional cigarette smoking among e-cigarette users and the onset of cigarette smoking.

Aim The aim of the current study was to evaluate tobacco product purchasing in the Experimental Tobacco Marketplace (ETM) among male and female smokers who also use e-cigarettes. We hypothesized a high substitution profile for e-cigarettes and that males would purchase more Snus than females. Methods The ETM is an online market used in clinical abuse liability research to mimic real-world purchasing patterns. Tobacco products, including each participant’s usual choice of conventional and e-cigarettes, were presented along with a price and description of nicotine content. Participants were endowed with an account balance based on the number of cigarettes and e-cigarettes consumed per week. Each participant was exposed to four ETM sessions in random order during which the price of conventional cigarettes was manipulated. Results Cigarette consumption decreased as price increased. A mixed factor three-way ANOVA revealed a significant main effect of price (i.e., more alternative products were purchased at higher cigarette prices), product (i.e., more e-cigarettes were purchased than gum, lozenges, and Snus), and sex (i.e., males purchased more than females). A significant three-way interaction indicated that males purchased more e-cigarettes, Snus, and dip than females at higher cigarette prices. Conclusion This study suggests that the user profile of cigarette smokers is associated with behavioral economic measures of alternative product substitution and indicates that the evaluation of nicotine replacement products should be considered for both males and females separately.

Electronic cigarettes (e-cigarettes) are increasingly used by US adolescents and may be a gateway to traditional cigarette use. We examine rates of both products by age and examine differences in age-varying rates by sex and race/ethnicity. Data are from the 2014 National Youth Tobacco Survey, a national sample of US middle and high school students (n=22.007); students ages 11-19 were included. Past 30-day e-cigarette and traditional cigarette use were examined as a function of age; sex and race/ethnicity were included as moderators. The age-varying association between e-cigarette and traditional cigarette use was also examined. Rates of e-cigarette use increase faster than traditional cigarette use from ages 13-16. Compared to females, males had higher rates of e-cigarette use from ages 14-17.5 and traditional cigarette use from ages 15-18. Between ages 12-14, more Hispanic adolescents used e-cigarettes compared to White or Black adolescents; after age 14 Hispanics and Whites reported similar rates, peaking at twice the rate for Blacks. Hispanic adolescents report greater traditional cigarette use versus Whites between ages 12-13, but lower rates between ages 15-18. E-cigarette use was strongly associated with traditional cigarette use, particularly during early adolescence [OR>40 before age 12]. Young Hispanic adolescents are at elevated risk for use of e-cigarettes and traditional cigarettes during early adolescence. During early adolescence, youth using e-cigarettes are more likely to smoke traditional cigarettes compared to youth not using e-cigarettes. The study of age-varying effects holds promise for advancing understanding of disparities in health risk behaviors. Copyright © 2016 Elsevier Ltd. All rights reserved.

The carcinogenic effect of {sup 210}Po and {sup 210}Pb with respect to lung cancer is an important problem in many countries with very high cigarette consumption. Poland has one of the highest consumptions of cigarettes in the world. The results of {sup 210}Po determination on the 14 most frequently smoked brands of cigarettes which constitute over 70% of the total cigarette consumption in Poland are presented and discussed. Moreover, the polonium content in cigarette smoke was estimated on the basis of its activity in fresh tobaccos, ash, fresh filters and post-smoking filters. The annual effective doses were calculated on the basis of {sup 210}Po and {sup 210}Pb inhalation with the cigarette smoke. The results of this work indicate that Polish smokers who smoke one pack (20 cigarettes) per day inhale from 20 to 215 mBq of {sup 210}Po and {sup 210}Pb each. The mean values of the annual effective dose for smokers were estimated to be 35 and 70 {mu}Sv from {sup 210}Po and {sup 210}Pb, respectively. For persons who smoke two packs of cigarettes with higher radionuclide concentrations, the effective dose is much higher (471 {mu}Sv yr{sup -1}) in comparison with the intake in diet. Therefore, cigarettes and the absorption through the respiratory system are the main sources and the principal pathway of {sup 210}Po and {sup 210}Pb intake of smokers in Poland.

The impact of taxation on tobacco consumption in Mexico.

The price of cigarettes to consumers in Mexico, and Latin America in general, remains low in comparison with other regions of the world. In Mexico, taxes represented 59% of the total price of cigarettes in 2006, compared to 75% or more in many high-income countries. The feasibility of raising taxes on cigarettes in Mexico--to both discourage consumption and increase revenues--is an important policy question. Using household survey data, we undertake a pooled cross-sectional analysis of the demand for cigarettes in Mexico. We use a two-part model to estimate the price elasticity of cigarettes. This model controls for the selection effect that arises from the fact that the impact of price on the decision to smoke or not is estimated using all households in the dataset. The results indicate that price is a significant factor in household decisions concerning smoking and the number of cigarettes smoked. Holding other factors constant, our simulations show that a 10% increase in the cigarette tax in Mexico--calculated as a percentage of the price--yields a 12.4% increase in the price to the consumer, a 6.4% decrease in consumption of cigarettes and a 15.7% increase in the revenue yielded by the tax. In Mexico, there are strong arguments for increasing cigarette taxes. Revenue raised could be used to further prevent tobacco consumption and to finance current funding shortages for the treatment of diseases related to smoking.

Full Text Available Background: It is thought that price increase in tobacco products leads to reduced consumption. Though many studies have substantiated this concept, it has not been well studied in India. Recently, price of tobacco products was increased due to ban on plastic sachets of chewing tobacco and increased tax in Rajasthan. This study was designed to evaluate the effect of price rise on overall consumption of tobacco in Jaipur city, Rajasthan. Materials and Methods: This study was carried out in Jaipur city. Two-staged stratified sampling was used. In the first phase of study, cost and consumption of various tobacco products in the months of February and April were enquired from 25 retail tobacco shops. In the second phase, tobacco consumption was enquired from 20 consecutive consumers purchasing any tobacco product from all the above retail tobacco shops. The data were statistically analyzed using descriptive statistics and paired "t" test. Results: The comparison of prices of tobacco products between February and April revealed that the price of cigarette, bidi, and chewing tobacco has increased by 19%, 21%, and 68%, respectively. Average decrease in sales of cigarettes, bidi, and chewing tobacco at shops included in the study were 14%, 23%, and 38%, respectively. The consumers purchasing tobacco also reported decreased consumption. Chewing tobacco showed the maximum reduction (21%. Consumption of cigarette and bidi has also reduced by 15% and 13%, respectively. Conclusion: It may be concluded that reduction in consumption is associated with increased price of tobacco products. Reduced consumption is comparative to the magnitude of price increase.

The distribution of cigarette prices has rarely been studied and compared under different tax structures. Descriptive evidence on price distributions by countries can shed light on opportunities for tax avoidance and brand switching under different tobacco tax structures, which could impact the effectiveness of increased taxation in reducing smoking. This paper aims to describe the distribution of cigarette prices by countries and to compare these distributions based on the tobacco tax structure in these countries. We employed data for 16 countries taken from the International Tobacco Control Policy Evaluation Project to construct survey-derived cigarette prices for each country. Self-reported prices were weighted by cigarette consumption and described using a comprehensive set of statistics. We then compared these statistics for cigarette prices under different tax structures. In particular, countries of similar income levels and countries that impose similar total excise taxes using different tax structures were paired and compared in mean and variance using a two-sample comparison test. Our investigation illustrates that, compared with specific uniform taxation, other tax structures, such as ad valorem uniform taxation, mixed (a tax system using ad valorem and specific taxes) uniform taxation, and tiered tax structures of specific, ad valorem and mixed taxation tend to have price distributions with greater variability. Countries that rely heavily on ad valorem and tiered taxes also tend to have greater price variability around the median. Among mixed taxation systems, countries that rely more heavily on the ad valorem component tend to have greater price variability than countries that rely more heavily on the specific component. In countries with tiered tax systems, cigarette prices are skewed more towards lower prices than are prices under uniform tax systems. The analyses presented here demonstrate that more opportunities exist for tax avoidance and brand

Interviews were conducted with 848 Glasgow children aged between 11 and 14 years. There were consistent differences between smokers and non-smokers. Smokers tended to be more adept at recalling, recognizing and identifying cigarette advertisements. This suggests they tend to pay more attention to cigarette advertising. Smokers also tended to be generally more appreciative of cigarette advertising. Moreover, this greater awareness and appreciation of cigarette advertising was independent of other important predictors of under-age smoking, such as smoking by peers, siblings and parents. These findings, taken in conjunction with previous research, indicate that cigarette advertising is reinforcing under-age smoking. The smokers showed an enhanced or heightened preference for Kensitas Club, the brand favoured by adults. This is consistent with previous research indicating that promotional devices which help determine and reinforce adult cigarette brand preferences have an even greater effect on under-age smokers.

E-cigarettes are the latest in a line of potentially reduced exposure products that have garnered interest among smokers. In this paper, we use experimental auctions to estimate smokers' demand for e-cigarettes and to assess the impact of advertisements on willingness to pay. These are actual auctions, with winners and losers, which means hypothetical biases often seen in surveys are minimized. We find smokers have positive demand for e-cigarettes, and that the print advertisements used in our study had greater effectiveness than video ads (b = 2.00, p e-cigarettes. Demand was greater for reusable versus disposable e-cigarettes. In multivariate models, demand for e-cigarettes was higher among non-white participants and among smokers willing to pay more for cigarettes. Our findings suggest that cigarette smokers are interested in e-cigarettes as alternatives to traditional products, particularly for reusable forms, and that this demand can be influenced by messaging/advertising. Given these reduced harm products are appealing, if smokers are able to switch completely to e-cigarettes, there is a good chance for accrual of significant harm reduction. © The Author 2016.

  The US Food and Drug Administration must consider whether to ban the use of menthol in cigarettes. This study examines how current smokers might respond to such a ban on menthol cigarettes.   Convenience sample of adolescent and adult smokers recruited from an online survey panel.   United States, 2010.   A total of 471 adolescent and adult current cigarette smokers.   Respondents were asked a series of questions about how they might react if menthol cigarettes were banned. In addition, participants completed a simulation purchase task to estimate the demand for menthol and non-menthol cigarettes across a range of prices.   Overall, 36.1% of respondents said they always (18.9%) or usually (17.2%) smoked menthol cigarettes. When asked how they might respond to a ban on menthol cigarettes, 35% of current menthol smokers said they would stop smoking, and 25% said they would 'find a way to buy a menthol brand'. Those who reported they might quit tended to have greater current intentions to quit [odds ratio (OR) = 4.47], while those who reported that they might seek illicit menthol cigarettes were far less likely to report current intentions to quit (OR = 0.06). Estimates for demand elasticity for preferred cigarette type were similar for menthol (α = 0.0051) and non-menthol (α = 0.0049) smokers. Demand elasticity and peak consumption were related to usual cigarette type and cigarettes smoked per day, but did not appear to differ by race, gender or age.   Preliminary evidence suggests that a significant minority of smokers of menthol cigarettes in the United States would try to stop smoking altogether if such cigarettes were banned. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

n-3 Highly unsaturated fatty acids (HUFA), are essential components of neuronal membranes and mediate a range of complex bioactive properties including gene expression, myelination, cell-signalling and dopaminergic function. Deficits in n-3 HUFA have been linked to increased risks for addictive disorders, thus we posited that lower fish consumption would be associated with greater risks for perinatal smoking among 9640 mothers enroled in the Avon Longitudinal Study of Parents and Children. We used univariable and multivariable regression models to examine relationships between self-reported prenatal dietary intakes of n-3 HUFA-rich foods (fish and shellfish) and maternal smoking; outcomes included cessation and the number of cigarettes smoked per d. Both before and during pregnancy, there was consistent evidence (Psmoking associations; relative to mothers reporting no fish consumption, those who reported some fish consumption (smoking (adjusted P values smoking diminished, from a high of 31·6% (pre-pregnancy) to a low of 18·7% (second trimester), the magnitude of fish intake-smoking associations remained stable following adjustment for confounders. These observations suggest that greater fish or n-3 HUFA consumption should be evaluated as an intervention to reduce or prevent smoking in randomised clinical trials.

Information on e-cigarettes among youth in the Russian Federation is lacking. We examined prevalence of and factors associated with youth e-cigarette use in the Russian Federation. A cross-sectional, anonymous survey, conducted among 716 (females 51.5%) high school students in three cities (i.e., Ufa, Sterlitamak, Karagaevo) within the Republic of Bashkortostan, Russian Federation in 2015, assessed e-cigarette use and its correlates (i.e., sex, age, ethnicity, family structure, parents' highest degrees, antisocial behaviors, stress coping strategies, lifetime cigarette, hookah, alcohol, and marijuana use). Lifetime use of e-cigarettes was 28.6% and past-30-day use was 2.2%. Multilevel modeling showed that belonging to Tatar/Bashkir ethnicity relative to Russian ethnicity (OR = 1.60) and lifetime use of cigarettes (OR = 21.64), hookah (OR = 4.21), and alcohol (OR = 1.90) was associated with greater odds of lifetime use of e-cigarettes. Furthermore, use of social support coping strategies (i.e., utilizing parents for support) were associated with lower odds of lifetime use of e-cigarettes (OR = 0.94). Despite high lifetime e-cigarette use, past-30-day use was low. Greater knowledge of the reasons for e-cigarette discontinuation through continued surveillance is needed in the Russian Federation. Social coping strategies involving parents may inform e-cigarette use prevention.

Full Text Available BACKGROUND: To illustrate the burden of high cigarette excise taxes on low-income smokers. METHODOLOGY/PRINCIPAL FINDINGS: Using data from the New York and national Adult Tobacco Surveys from 2010-2011, we estimated how smoking prevalence, daily cigarette consumption, and share of annual income spent on cigarettes vary by annual income (less than $30,000; $30,000-$59,999; and more than $60,000. The 2010-2011 sample includes 7,536 adults and 1,294 smokers from New York and 3,777 adults and 748 smokers nationally. Overall, smoking prevalence is lower in New York (16.1% than nationally (22.2% and is strongly associated with income in New York and nationally (P<.001. Smoking prevalence ranges from 12.2% to 33.7% nationally and from 10.1% to 24.3% from the highest to lowest income group. In 2010-2011, the lowest income group spent 23.6% of annual household income on cigarettes in New York (up from 11.6% in 2003-2004 and 14.2% nationally. Daily cigarette consumption is not related to income. CONCLUSIONS/SIGNIFICANCE: Although high cigarette taxes are an effective method for reducing cigarette smoking, they can impose a significant financial burden on low-income smokers.

Full Text Available Electronic cigarettes (ECs are battery-operated devices designed to vaporise nicotine, which may help smokers with quitting or reducing their tobacco consumption. No data is available regarding the health effects of ECs use among smokers with arterial hypertension and whether regular use results in blood pressure (BP changes. We investigated long-term changes in resting BP and level of BP control in hypertensive smokers who quit or reduced substantially their tobacco consumption by switching to ECs. A medical records review of patients with hypertension was conducted to identify patients reporting regular daily use of ECs on at least two consecutive follow-up visits. Regularly smoking hypertensive patients were included as a reference group. A marked reduction in cigarette consumption was observed in ECs users (n = 43 though consumption remained unchanged in the control group (n = 46. Compared to baseline, at 12 months (follow-up visit 2 decline in cigarette consumption was associated with significant reductions in median (25th-, 75th-centile systolic BP (140 (134.5, 144 to 130 (123.5, 138.5 mmHg; p < 0.001 and diastolic BP (86 (78, 90 to 80 (74.5, 90 mmHg; p = 0.006. No significant changes were observed in the control group. As expected, decline in cigarette consumption in the ECs users was also associated with improved BP control. The study concludes that regular ECs use may aid smokers with arterial hypertension reduce or abstain from cigarette smoking, with only trivial post-cessation weight gain. This resulted in improvements in systolic and diastolic BP as well as better BP control.

Adolescents' use of electronic cigarettes (e-cigarettes) and exposure to e-cigarette TV advertising have increased in recent years, despite questions about their safety. The current study tests whether exposure to e-cigarette TV advertisements influences intentions to use e-cigarettes in the future and related attitudes. A parallel-group randomized controlled experiment was conducted and analyzed in 2014 using an online survey with a convenience sample of 3,655 U.S. adolescents aged 13-17 years who had never tried e-cigarettes. Adolescents in the treatment group viewed four e-cigarette TV advertisements. Adolescents in the treatment group reported a greater likelihood of future e-cigarette use compared with the control group. ORs for the treatment group were 1.54 (p=0.001) for trying an e-cigarette soon; 1.43 (p=0.003) for trying an e-cigarette within the next year; and 1.29 (p=0.02) for trying an e-cigarette if a best friend offered one. Adolescents in the treatment group had higher odds of agreeing that e-cigarettes can be used in places where cigarettes are not allowed (OR=1.71, pe-cigarette advertising had relatively large and consistent effects across experimental outcomes. Together with the simultaneous increase in e-cigarette advertising exposure and e-cigarette use among adolescents, findings suggest that e-cigarette advertising is persuading adolescents to try this novel product. This raises concerns that continued unregulated e-cigarette advertising will contribute to potential individual- and population-level harm. Copyright © 2015 American Journal of Preventive Medicine.

Estimates of e-cigarette consumption in Germany vary considerably. The use of e-cigarettes for tobacco cessation is critically discussed. Based on current data, the distribution of the consumption of e-cigarettes and their use in the adult general population of Germany will be presented. The 2015 Epidemiological Survey of Substance Abuse, a nationwide survey of 18 to 64 year-old people in Germany (n=9,204, response rate: 52,2%), was used as data basis. E-cigarettes were known to most of the respondents (85,3%, 43,5 Mio.), whereas only 2,9% (1,5 Mio.) used e-cigarettes in the last 30 days. Higher risk of consuming e-cigarettes was seen in younger people (OR=0,95, 95%-KI=(0,93; 0,97)), men (OR=1,45, 95%-KI=(1,02; 2,07)) and smokers (OR=12,53, 95%-KI=(8,71; 18,03)). About a third of smokers and ex-smokers of conventional cigarettes (36,6%) who consumed e-cigarettes used these for tobacco cessation of which one fifth (21,3%) was able to quit smoking. E-cigarette users seem to be more likely to be male, younger and smokers of conventional cigarettes. In addition to curiosity, the change in smoking behavior is an important motive for consumption. The results indicate that the use of e-cigarettes can contribute to tobacco cessation, the majority of users, however, continue to consume conventional and/or e-cigarettes. © Georg Thieme Verlag KG Stuttgart · New York.

2015-08-01

Recent human studies confirm animal research showing that nicotine enhances reinforcement from rewards unrelated to nicotine. These effects of acute nicotine via tobacco smoking may also occur when consumed from non-tobacco products. We assessed acute effects of nicotine via electronic cigarettes ("e-cigarettes") on responding reinforced by music, video, or monetary rewards, or for no reward (control). In a fully within-subjects design, adult dependent smokers (N=28) participated in three similar experimental sessions, each following overnight abstinence (verified by CO≤10ppm). Varying only in e-cigarette condition, sessions involved controlled exposure to a nicotine (labeled "36mg/ml") or placebo ("0″) e-cigarette, or no e-cigarette use. A fourth session involved smoking one's own tobacco cigarette brand after no abstinence, specifically to compare responses under typical nicotine satiation with these acute e-cigarette conditions after abstinence. Reinforced responding for video reward, but not the other rewards, was greater due to use of the nicotine versus placebo e-cigarette (i.e., nicotine per se), while no differences were found between the placebo e-cigarette and no e-cigarette conditions (i.e., e-cigarette use per se). For nicotine via tobacco smoking, responding compared to the nicotine e-cigarette was similar for video but greater for music, while both video and music reward were enhanced relative to the non-nicotine conditions (placebo and no e-cigarette). Acute nicotine from a non-tobacco product has some reinforcement enhancing effects in humans, in a manner partly consistent with nicotine via tobacco smoking and perhaps contributing to the rising popularity of nicotine e-cigarette use.

Why ban the sale of cigarettes? The case for abolition.

Science.gov (United States)

Proctor, Robert N

2013-05-01

The cigarette is the deadliest artefact in the history of human civilisation. Most of the richer countries of the globe, however, are making progress in reducing both smoking rates and overall consumption. Many different methods have been proposed to steepen this downward slope, including increased taxation, bans on advertising, promotion of cessation, and expansion of smoke-free spaces. One option that deserves more attention is the enactment of local or national bans on the sale of cigarettes. There are precedents: 15 US states enacted bans on the sale of cigarettes from 1890 to 1927, for instance, and such laws are still fully within the power of local communities and state governments. Apart from reducing human suffering, abolishing the sale of cigarettes would result in savings in the realm of healthcare costs, increased labour productivity, lessened harms from fires, reduced consumption of scarce physical resources, and a smaller global carbon footprint. Abolition would also put a halt to one of the principal sources of corruption in modern civilisation, and would effectively eliminate one of the historical forces behind global warming denial and environmental obfuscation. The primary reason for abolition, however, is that smokers themselves dislike the fact they smoke. Smoking is not a recreational drug, and abolishing cigarettes would therefore enlarge rather than restrict human liberties. Abolition would also help cigarette makers fulfil their repeated promises to 'cease production' if cigarettes were ever found to be causing harm.

Full Text Available Electronic cigarette (e-cigarette is a device developed with an intent to enable smokers to quit smoking and avoid the unhealthful effects of cigarettes. The popularity of e-cigarette has increased rapidly in recent years. The increase in its use during the adolescence period is attention-grabbing. Despite the fact that e-cigarette has become popular in a dramatic way, there are certain differences of opinion regarding its long-term effects on health, in particular. While some people assert that it is less harmful than conventional cigarettes, some others assert the contrary. Although e-cigarette contains less toxic substances compared to conventional cigarette, it contains certain carcinogens existing in conventional cigarette such as formaldehyde and acetaldehyde. It also contains heavy metals (nickel, chrome that conventional cigarette does not contain; and therefore, raises concerns about health. E-cigarette leads to upper and lower respiratory tract irritation as well as an increased airway resistance and an increased bacterial colonization in the respiratory tract. It may also cause tahcycardia and increase diastolic blood pressure. Although e-cigarette has been found to have certain benefits in terms of smoking cessation, most of the studies have shown unfavorable results. In this collected work, the effects of e-cigarette on health and its role in smoking cessation are discussed in detail.

Full Text Available Evidence indicates that breakfast consumption is associated with a cluster of health-related behaviors, yet studies in mainland China are scarce. This study is conducted to describe the frequency of breakfast consumption among Chinese adolescents and examine its associations with other dietary, physical activity, sedentary, sleep, cigarette-smoking, and alcohol-drinking behaviors. Breakfast consumption and other health-related behaviors data was collected via a self-administered questionnaire in a cross-sectional study in Zhejiang Province, China. A total of 19,542 school-aged adolescents were recruited in this survey. The associations between breakfast consumption and other health-related behaviors were examined using logistic regression models. A significantly higher prevalence of daily breakfast consumption was found among students who were younger (p for trend <0.001, from urban schools (p < 0.001, and academic high schools (p < 0.001. More frequent vegetable and milk consumption, greater physical activity, and longer sleep duration were positively associated with daily breakfast consumption, while soft drinks and fast food consumption, computer use, cigarette-smoking and alcohol-drinking behaviors were inversely associated. The prevalence of irregular breakfast consumption was relatively high among Chinese adolescents in Zhejiang Province. Daily breakfast consumption was associated with a constellation of health-related behaviors.

Estimate price elasticity of demand for cigarettes and alcohol in Ecuador using cross-sectional data from the National Survey of Urban and Rural Household Income and Expenditures (ENIGHUR is the acronym in Spanish) 2011-2012. ENIGHUR 2011-2012 data were used with Deaton's (1, 2) methodology to estimate price elasticity of demand for cigarettes and alcohol with expenditure and quantity information. Household socioeconomic variables were also included. Price elasticity of demand for cigarettes is -0.87, meaning that a 10% price increase could lead to an 8.7% decrease in consumption. Results for cross-price elasticities of alcohol on cigarette demand are negative, as expected, indicating that they are complementary goods; however, the results are not statistically significant. Furthermore, it was found that price elasticity of demand for alcohol is -0.44, meaning that a 10% increase in the price of alcohol would produce a 4.4% decrease in consumption. A policy of price increases, for example, with a tax increase, applied to both cigarettes and alcohol, could have a positive effect on public health through reductions in consumption of both goods. However, this measure would not be sufficient to bridge gaps in prevalence measures and health outcomes between sex and other population groups, given the observed difference in the sensitivity of consumption to price variations.

This article describes the perception of health risks in adolescents due to the consumption of cigarettes, alcohol and psychoactive substances in the Federation of Bosnia and Herzegovina (FBIH), as well as their observation of the behavior of their peers related to addictive behaviors. For the analysis was used a database from the European School Survey Project on Alcohol and Other Drugs (ESPAD) survey which was conducted in FBIH in 2011. The target population were students in the second grade of secondary schools in FBIH born in 1995 according to the ESPAD protocol. The total number of respondents from the cohort born in 1995 was 3813 students. The research results showed that the prevalence of risk perception due to the consumption of cigarettes, alcohol and psychoactive substances among adolescents in the FBIH is lower than the mean prevalence in countries which have implemented the ESPAD survey of 2011. PPreventive activities should be aimed at adolescent risk behaviours and empower them to make the right decisions that can have far reaching significance. Attention has to be paid to selective prevention that is directed towards individuals or subgroup of population where the risk of developing disorder is much higher than average.

There is conflicting evidence that use of e-cigarettes promotes cessation in regular smokers, but contrasting findings may be due to differing definitions of vaping. The aim was to assess whether regular use of e-cigarettes while smoking is associated with subsequent smoking cessation. Baseline internet survey with outcomes measured at 6-month follow-up. All French metropolitan territory. A total of 2057 smokers aged 15-85 years were recruited through an access panel and responded to a 6-month follow-up: 1805 exclusive tobacco smokers and 252 dual users (tobacco plus regular e-cigarette users) at baseline. The three outcomes assessed at 6 months were: a minimum 50% reduction in the number of cigarettes smoked per day, quit attempts of at least 7 days and smoking cessation of at least 7 days at the time of follow-up. Logistic regressions were performed to model the three outcomes according to regular e-cigarette use at baseline, adjusted for socio-economic variables and smoking behaviours. Baseline dual users were more likely than baseline exclusive tobacco smokers to have halved cigarette consumption [25.9 versus 11.2%, P e-cigarette regularly are more likely to try to quit smoking and reduce their cigarette consumption during the next 6 months. It remains unclear whether regular e-cigarette users are also more likely to stop smoking. © 2017 Society for the Study of Addiction.

Coffee consumption and cigarette smoking are strongly associated, but whether this association is causal remains unclear. We sought to: (1) determine whether coffee consumption influences cigarette smoking causally, (2) estimate the magnitude of any association and (3) explore potential mechanisms. We used Mendelian randomization (MR) analyses of observational data, using publicly available summarized data from the Tobacco and Genetics (TAG) consortium, individual-level data from the UK Biobank and in-vitro experiments of candidate compounds. The TAG consortium includes data from studies in several countries. The UK Biobank includes data from men and women recruited across England, Wales and Scotland. The TAG consortium provided data on n ≤ 38 181 participants. The UK Biobank provided data on 8072 participants. In MR analyses, the exposure was coffee consumption (cups/day) and the outcome was heaviness of smoking (cigarettes/day). In our in-vitro experiments we assessed the effect of caffeic acid, quercetin and p-coumaric acid on the rate of nicotine metabolism in human liver microsomes and cDNA-expressed human CYP2A6. Two-sample MR analyses of TAG consortium data indicated that heavier coffee consumption might lead to reduced heaviness of smoking [beta = -1.49, 95% confidence interval (CI) = -2.88 to -0.09]. However, in-vitro experiments found that the compounds investigated are unlikely to inhibit significantly the rate of nicotine metabolism following coffee consumption. Further MR analyses in UK Biobank found no evidence of a causal relationship between coffee consumption and heaviness of smoking (beta = 0.20, 95% CI = -1.72 to 2.12). Amount of coffee consumption is unlikely to have a major causal impact upon amount of cigarette smoking. If it does influence smoking, this is not likely to operate via effects of caffeic acid, quercetin or p-coumaric acid on nicotine metabolism.

Full Text Available Recycling nutrients form sanitary wastes back into agricultural ecosystems offers an option to alleviate soil depletion in regions where the use of mineral fertiliser is limited. Exemplary nutrient and water cycling approaches, including collection, treatment and use of human urine, are established at Valley View University (VVU in Greater Accra, Ghana.Concerns have been recently raised in regard to fate and impact of pharmaceutical residues in soils and interlinked environment. To evaluate in how far emerging knowledge can be transposed onto VVU, urban and rural environments in Greater Accra, spatial disease occurrence and drug consumption patterns were studied. Malaria has been found to represent the most severe health burden in Ghana, but there is also a high prevalence of infectious diseases. Drugs consumed in great quantities and in respect to their residual loads potentially problematic in the environment belong to therapeutic groups of: antibiotics, analgesics, drugs for diabetes, antimalarials, cardiovascular drugs and anthelmintics. Drug consumption revealed to be highest in urban and lowest in rural areas. At VVU the range of consumed drugs is comparable to urban areas except for the negligible use of diabetes and cardiovascular medication as well as contraceptives.

To examine patterns of adolescent sports and energy drink (SED) consumption and identify behavioral correlates. Data were drawn from Eating and Activity in Teens, a population-based study. Adolescents from 20 middle and high schools in Minneapolis/St Paul, MN completed classroom-administered surveys. A total of 2,793 adolescents (53.2% girls) in grades 6-12. Beverage patterns; breakfast frequency; moderate to vigorous physical activity (MVPA); media use; sleep; and cigarette smoking. Linear and logistic regression models were used to estimate associations between health behaviors and SED consumption, adjusting for demographics. Over a third of adolescents consumed sports drinks and 14.7% consumed energy drinks at least once a week. Among boys and girls, both sports and energy drink consumption were related to higher video game use; sugar-sweetened beverage and fruit juice intake; and smoking (P Sports drink consumption was also significantly related to higher MVPA and organized sport participation for both genders (P sports drink consumption was associated with higher MVPA, adolescents should be reminded of recommendations to consume these beverages only after vigorous, prolonged activity. There is also a need for future interventions designed to reduce SED consumption, to address the clustering of unhealthy behaviors. Copyright © 2014 Society for Nutrition Education and Behavior.

E-cigarette use has increased rapidly among U.S. adults. However, reasons for use among adults are unclear. We assessed reasons for e-cigarette use among a national sample of U.S. adults. Data were collected via online surveys among U.S. adults aged 18 or older from April through June 2014. Descriptive and multivariate regression analyses were conducted to assess reasons for e-cigarette use among 2448 current e-cigarette users, by sociodemographic characteristics and product type. Assessed reasons included cessation/health, consideration of others, convenience, cost, curiosity, flavoring, and simulation of conventional cigarettes. Among current e-cigarette users, 93% were also current cigarette smokers. The most common reasons for e-cigarette use were cessation/health (84.5%), consideration of others (71.5%), and convenience (56.7%). The prevalence of citing convenience (adjusted prevalence ratio [aPR]=1.49) and curiosity (aPR=1.54) as reasons for e-cigarette use were greater among current cigarette smokers than nonsmokers (Preason for use was greater among adults aged 18 to 24 (aPR=2.02) than 55 or older (Preason except convenience and curiosity. Cessation- and health-related factors are primary reasons cited for e-cigarette use among adults, and flavorings are more commonly cited by younger adults. Efforts are warranted to provide consumers with accurate information on the health effects of e-cigarettes and to ensure that flavoring and other unregulated features do not promote nicotine addiction, particularly among young adults.

State cigarette minimum price laws - United States, 2009.

Science.gov (United States)

2010-04-09

Cigarette price increases reduce the demand for cigarettes and thereby reduce smoking prevalence, cigarette consumption, and youth initiation of smoking. Excise tax increases are the most effective government intervention to increase the price of cigarettes, but cigarette manufacturers use trade discounts, coupons, and other promotions to counteract the effects of these tax increases and appeal to price-sensitive smokers. State cigarette minimum price laws, initiated by states in the 1940s and 1950s to protect tobacco retailers from predatory business practices, typically require a minimum percentage markup to be added to the wholesale and/or retail price. If a statute prohibits trade discounts from the minimum price calculation, these laws have the potential to counteract discounting by cigarette manufacturers. To assess the status of cigarette minimum price laws in the United States, CDC surveyed state statutes and identified those states with minimum price laws in effect as of December 31, 2009. This report summarizes the results of that survey, which determined that 25 states had minimum price laws for cigarettes (median wholesale markup: 4.00%; median retail markup: 8.00%), and seven of those states also expressly prohibited the use of trade discounts in the minimum retail price calculation. Minimum price laws can help prevent trade discounting from eroding the positive effects of state excise tax increases and higher cigarette prices on public health.

Following cigarette excise tax increases, smokers may use cigarette price minimization strategies to continue their usual cigarette consumption rather than reducing consumption or quitting. This reduces the public health benefits of the tax increase. This paper estimates the price reductions for a wide-range of strategies, compensating for overlapping strategies. We performed regression analysis on the 2009-2010 National Adult Tobacco Survey (N=13,394) to explore price reductions that smokers in the United States obtained from purchasing cigarettes. We examined five cigarette price minimization strategies: 1) purchasing discount brand cigarettes, 2) using price promotions, 3) purchasing cartons, 4) purchasing on Indian reservations, and 5) purchasing online. Price reductions from these strategies were estimated jointly to compensate for overlapping strategies. Each strategy provided price reductions between 26 and 99cents per pack. Combined price reductions were possible. Additionally, price promotions were used with regular brands to obtain larger price reductions than when price promotions were used with generic brands. Smokers can realize large price reductions from price minimization strategies, and there are many strategies available. Policymakers and public health officials should be aware of the extent that these strategies can reduce cigarette prices. Published by Elsevier Inc.

In recent years, electronic cigarettes have gained increasing popularity as alternatives to normal (tobacco-containing) cigarettes. In the present study, particles generated by e-cigarettes and normal cigarettes have been analyzed and the degree of exposure to different chemical agents and their emission rates were quantified. Despite the 10-fold decrease in the total exposure to particulate elements in e-cigarettes compared to normal cigarettes, specific metals (e.g. Ni and Ag) still displayed a higher emission rate from e-cigarettes. Further analysis indicated that the contribution of e-liquid to the emission of these metals is rather minimal, implying that they likely originate from other components of the e-cigarette device or other indoor sources. Organic species had lower emission rates during e-cigarette consumption compared to normal cigarettes. Of particular note was the non-detectable emission of polycyclic aromatic hydrocarbons (PAHs) from e-cigarettes, while substantial emission of these species was observed from normal cigarettes. Overall, with the exception of Ni, Zn, and Ag, the consumption of e-cigarettes resulted in a remarkable decrease in secondhand exposure to all metals and organic compounds. Implementing quality control protocols on the manufacture of e-cigarettes would further minimize the emission of metals from these devices and improve their safety and associated health effects.

The objective of this paper is to estimate the demand for tar and nicotine in cigarettes as a function of cigarette prices in a cohort of cigarette 11,966 smokers followed for 5 years. Data for the analysis come from a longitudinal telephone survey of 11,966 smokers who were interviewed in 1988 and 1993 as part of the Community Intervention Trial for Smoking Cessation (COMMIT). Separate models are estimated for three age groups to account for differences in levels of addiction and brand loyalty across age. We found that smokers respond to higher cigarette prices by reducing the number of cigarettes smoked per day but also by switching to cigarettes that are higher in tar and nicotine per cigarette.

This work analyzes the effects of prices, taxes, income, and anti-smoking regulations on the consumption of cigarettes in California (a 25-cent-per-pack state tax increase in 1989 enhances the usefulness of this exercise). Analysis is based on monthly time-series data for 1980 through 1990. Results show a price elasticity of demand for cigarettes in the short run of -0.3 to -0.5 at mean data values, and -0.5 to -0.6 in the long run. We find at least some support for two further hypotheses: that antismoking regulations reduce cigarette consumption, and that consumers behave consistently with the model of rational addiction.

Is Every Smoker Interested in Price Promotions? An Evaluation of Price-Related Discounts by Cigarette Brands.

Xu, Xin; Wang, Xu; Caraballo, Ralph S

2016-01-01

Raising unit price is one of the most effective ways of reducing cigarette consumption. A large proportion of US adult smokers use generic brands or price discounts in response to higher prices, which may mitigate the public health impacts of raising unit price. The main purpose of this study was to evaluate the retail price impact and the determinants of price-related discount use among US adult smokers by their most commonly used cigarette brand types. Data from the 2009-2010 National Adult Tobacco Survey, a telephone survey of US adults 18 years or older, was used to assess price-related discount use by cigarette brands. Price-related discounts included coupons, rebates, buy 1 get 1 free, 2 for 1, or any other special promotions. Multivariate logistic regression was used to assess sociodemographic and tobacco use determinants of discount use by cigarette brands. Discount use was most common among premium brand users (22.1%), followed by generic (13.3%) and other brand (10.8%) users. Among premium brand users, those who smoked 10 to 20 cigarettes per day were more likely to use discounts, whereas elderly smokers, non-Hispanic blacks, those with greater annual household income, dual users of cigarettes and other combustible tobacco products, and those who had no quit intentions were less likely to do so. Among generic brand users, those who had no quit intentions and those who smoked first cigarette within 60 minutes after waking were more likely to use discounts. Frequent use of discounts varies between smokers of premium and generic cigarette brands. Setting a high minimum price, together with limiting the use of coupons and promotions, may uphold the effect of cigarette excise taxes to reduce smoking prevalence.

Although the prevalence of e-cigarette use among adolescents and young adults has caught up to or eclipsed that of combustible cigarette use, there is relatively little known about (a) the link between e-cigarettes and other substances and (b) the reasons underlying this increase in e-cigarette use. To address this gap in knowledge, the current study examined associations between e-cigarette use and other substances and identified motives for e-cigarette use among young adults. Participants included an ethnically diverse sample of African American, White, and Hispanic young adults (N = 662; 61% female) who were participating in an ongoing survey-based longitudinal study of health and risky behaviors. Hispanic, White, and male young adults reported significantly greater past year e-cigarette use compared to their African American and female counterparts. Bivariate correlations showed that use of e-cigarettes was positively associated with use of combustible cigarettes, alcohol, marijuana, cocaine, amphetamines, inhalants, hallucinogens, ecstasy, and misuse of over-the-counter and prescription medications. Furthermore, e-cigarette users reported a higher prevalence of substance use relative to those who did not use e-cigarettes. The taste of e-cigarettes was identified as an important motive for use. Although the potential harm associated with e-cigarettes remains largely unknown, e-cigarettes appear to be a risk marker for the use of substances that are known to pose substantial health problems. Health care providers should screen for e-cigarette use, and youth substance use prevention programs should target the reduction of e-cigarette use with particular attention to addressing their taste appeal.

The major objective of this project is to obtain experimental data that are directly applicable to resolving the question of whether cigarette smokers are at greater risk than nonsmokers to potential health effects of inhaled plutonium. Progress was made on two fronts during the past year. The autoradiographic technique developed from detection of plutonium on the interior surface of pulmonary airways (Annual Report, 1978) has been adapted to routine use in examining tracheas and bronchi of rats. Also, dogs exposed to cigarette smoke for over a year after inhalation of plutonium were killed and necropsied

How the brain processes cigarette cost-benefit decision making remains largely unknown. Using functional magnetic resonance imaging (fMRI), this study investigated the neural correlates of decisions for cigarettes (0-10 cigarettes) at varying levels of price during a Cigarette Purchase Task (CPT) in male regular smokers (N = 35). Differential neural activity was examined between choices classified as inelastic, elastic, and suppressed demand, operationalized as consumption unaffected by cost, partially suppressed by cost, and entirely suppressed by cost, respectively. Decisions reflecting elastic demand, putatively the most effortful decisions, elicited greater activation in regions associated with inhibition and planning (e.g., middle frontal gyrus and inferior frontal gyrus), craving and interoceptive processing (anterior insula), and conflict monitoring (e.g., anterior cingulate cortex). Exploratory examination in a harmonized dataset of both cigarette and alcohol demand (N = 59) suggested common neural activation patterns across commodities, particularly in the anterior insula, caudate, anterior cingulate, medial frontal gyrus, and dorsolateral prefrontal cortex. Collectively, these findings provide initial validation of a CPT fMRI paradigm; reveal the interplay of brain regions associated with executive functioning, incentive salience, and interoceptive processing in cigarette decision making; and add to the literature implicating the insula as a key brain region in addiction.

Is there a role for e-cigarettes in smoking cessation?

Science.gov (United States)

Leduc, Charlotte; Quoix, Elisabeth

2016-04-01

The use of e-cigarettes has dramatically increased over the past few years and their role in smoking cessation remains controversial. Several clinical studies have evaluated their efficacy in smoking cessation but most of them are prospective cohort studies. Only two randomized, controlled trials have compared e-cigarettes versus placebo or patches. A meta-analysis of these two randomized, controlled trials has been performed. Nicotine-containing e-cigarettes appear to help smokers unable to stop smoking altogether to reduce their cigarette consumption when compared with placebo. However, these results are rated 'low' by GRADE standards. Many cohort studies have been conducted, with contradictory results. For some, e-cigarettes could increase the risk of nonsmokers developing nicotine dependence and of current smokers maintaining their dependence. The debate remains open and more randomized trials are needed with long-term data about the efficacy and safety of e-cigarettes. © The Author(s), 2015.

Full Text Available Cigarette smoking causes numerous adverse biochemical changes in plasma and blood leading to ill health effects for which therapeutic approaches are sought. The present study investigates the effect of green tea consumption on confirmed cigarette smokers. Blood samples were collected from 120 selected human male volunteers categorized in to four groups viz., controls, smokers, control volunteers consuming green tea with no habit of smoking and smokers consuming green tea were analysed. Results showed that altered plasma glucose, HbA1c, hemoglobin, hematocrit, total cholesterol, lipoprotein patterns (HDL, LDL, VLDL and lipid peroxidation along with vitamins (vitamin-D, vitamin-B12, vitamin-C and minerals (iron, total iron binding capacity, calcium, sodium, potassium, phosphorous, chloride followed by the activities of alanine aminotransferase (ALT, aspartate aminotransferase (AST, gamma glutamyl transferase (γGT and alkaline phosphatase (ALP. Furthermore, phytochemical analysis of green tea confirmed the presence of phenols, flavonoids and tannins. Antioxidants and free radical scavenging effects of green tea were assessed using 2, 2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS+ and 2, 2-diphenyl-1-picrylhydrazyl (DPPH+. Results of this study clearly demonstrated that the adverse changes observed in the above biochemical parameters in smokers were reversed upon green tea supplementation which can be attributed to the phytoconstituents present in green tea. In conclusion, both in vivo and in vitro studies revealed that phytocompounds present in green tea are able to scavenge free radicals and by there offers protection against smoking induced biochemical alterations.

Trends and affordability of cigarette prices: ample room for tax increases and related health gains.

Increasing the price of tobacco products is arguably the most effective method of curbing the prevalence and consumption of tobacco products. Price increases would reduce the global burden of disease brought about by tobacco consumption. To compare cigarette price data from more than 80 countries using varying methods, examine trends in prices and affordability during the 1990s, and explore various policy implications pertaining to tobacco prices. March 2001 cigarette price data from the Economist Intelligence Unit are used to compare cigarette prices across countries. To facilitate comparison and to assess affordability, prices are presented in US dollars, purchasing power parity (PPP) units using the Big Mac index as an indicator of PPP and in terms of minutes of labour required to purchase a pack of cigarettes. Annual real percentage changes in cigarette prices between 1990 and 2000 and annual changes in the minutes of labour required to buy cigarettes between 1991 and 2000 are also calculated to examine trends. Cigarette prices tend to be higher in wealthier countries and in countries that have strong tobacco control programmes. On the other hand, minutes of labour required to purchase cigarettes vary vastly between countries. Trends between 1990 and 2000 in real prices and minutes of labour indicate, with some exceptions, that cigarettes have become more expensive in most developed countries but more affordable in many developing countries. However, in the UK, despite recent increases in price, cigarettes are still more affordable than they were in the 1960s. The results suggest that there is ample room to increase tobacco prices through taxation. In too many countries, cigarette prices have failed to keep up with increases in the general price level of goods and services, rendering them more affordable in 2000 than they were at the beginning of the decade. Opportunities to increase government revenue and improve health through reduced consumption brought

Using an automated method of calculating airways resistance in the body plethysmograph, we have investigated changes occurring immediately after inhalation of cigarette smoke. Decreases in specific conductance occurred by the time of the first measurement seven or eight seconds after exposure to single inhalations of cigarette smoke in 12 smokers and 12 non-smokers. Less than half of the initial change was present 40 seconds after the inhalation. Initial responses were greater in the non-smokers. Responses recurred with repeated inhalations in smokers and non-smokers. Prior administration of salbutamol and ipratropium bromide significantly inhibited the response and this inhibition appeared to be greater in non-smokers. Sodium cromoglycate inhaled as a dry powder had no effect on the response.

The empirical analysis of cigarette tax avoidance and illicit trade in Vietnam, 1998-2010.

Full Text Available Illicit trade carries the potential to magnify existing tobacco-related health care costs through increased availability of untaxed and inexpensive cigarettes. What is known with respect to the magnitude of illicit trade for Vietnam is produced primarily by the industry, and methodologies are typically opaque. Independent assessment of the illicit cigarette trade in Vietnam is vital to tobacco control policy. This paper measures the magnitude of illicit cigarette trade for Vietnam between 1998 and 2010 using two methods, discrepancies between legitimate domestic cigarette sales and domestic tobacco consumption estimated from surveys, and trade discrepancies as recorded by Vietnam and trade partners. The results indicate that Vietnam likely experienced net smuggling in during the period studied. With the inclusion of adjustments for survey respondent under-reporting, inward illicit trade likely occurred in three of the four years for which surveys were available. Discrepancies in trade records indicate that the value of smuggled cigarettes into Vietnam ranges from $100 million to $300 million between 2000 and 2010 and that these cigarettes primarily originate in Singapore, Hong Kong, Macao, Malaysia, and Australia. Notable differences in trends over time exist between the two methods, but by comparison, the industry estimates consistently place the magnitude of illicit trade at the upper bounds of what this study shows. The unavailability of annual, survey-based estimates of consumption may obscure the true, annual trend over time. Second, as surveys changed over time, estimates relying on them may be inconsistent with one another. Finally, these two methods measure different components of illicit trade, specifically consumption of illicit cigarettes regardless of origin and smuggling of cigarettes into a particular market. However, absent a gold standard, comparisons of different approaches to illicit trade measurement serve efforts to refine

The effect of taxation on tobacco consumption and public revenues in Lebanon.

Science.gov (United States)

Salti, Nisreen; Chaaban, Jad; Nakkash, Rima; Alaouie, Hala

2015-01-01

Tobacco consumption rates in Lebanon are among the highest worldwide. The country ratified the Framework Convention on Tobacco Control in 2005. A law was passed in 2011 which regulates smoking in closed public spaces, bans advertising, and stipulates larger warnings. Despite international evidence confirming that increasing taxation on tobacco products lowers tobacco consumption, no such policy has yet been adopted: a cigarette pack costs on average US$1.50. To date no studies in Lebanon have addressed the welfare and public finance effects of increasing taxes on tobacco products. Using the 2005 national survey of household living conditions, we estimate an almost ideal demand system to generate price elasticities of demand for tobacco. Using estimated elasticities and a conservative scenario for expected smuggling, we simulate the consumption and tax revenue effects of a change in the price of tobacco under various tax schemes. Increasing taxes on all tobacco products so as to double the price of imported cigarettes would lower their consumption by 7% and consumption of domestically produced cigarettes by over 90%. Young adults (ages 15-30) are more sensitive: consumption would drop by 9% for imported cigarettes and by 100% for domestic cigarettes. Government revenues would increase by approximately 52%. The estimated elasticities indicate that an increase in taxes on all tobacco products would lead to a reduction in consumption and an increase in government revenue. Evidence from Lebanon on the effectiveness of increased taxation may help initiate national debate on the need to raise taxes. Published by the BMJ Publishing Group Limited.

Exploring the impact of foreign direct investment on tobacco consumption in the former Soviet Union.

Gilmore, A B; McKee, M

2005-02-01

Tobacco is the single largest cause of morbidity and mortality in the developed world; in the former socialist bloc tobacco kills twice as many men as in the west. Although evidence shows that liberalisation of the cigarette trade through the elimination of import barriers leads to significant increases in consumption, far less is known about the impact of foreign direct investment on cigarette consumption. This paper seeks to explore the impact that the substantial transnational tobacco company investments have had on patterns of tobacco trade and consumption in the former Soviet Union. Routine data were used to explore trends in cigarette trade and consumption in the 15 countries of the former Soviet Union from the 1960s to the present day. Comparisons were made between trends in countries that have received substantial investment from the tobacco transnationals and countries that have not. Between 1991 and 2000 cigarette production increased by 96% in countries receiving industry investment and by 11% in countries that did not. Over the same period cigarette consumption increased by 40%; the increase was concentrated in countries receiving investments. Despite these investments, cigarette imports still outweigh exports and no trade surplus has yet to result. The findings suggest that liberalisation of inward investment has a significant and positive impact on cigarette consumption and that without appropriate safeguards, market liberalisation may have long term negative impacts on health. Specific trade rules are needed to govern trade and investment in this uniquely harmful product. Implementation of effective tobacco control policies should precede tobacco industry privatisation. International financial organisations pressing for privatisation should ensure this occurs.

Although adolescents are a group heavily targeted by the e-cigarette industry, research in cue-reactivity has not previously examined adolescents' behavioral and neural responses to e-cigarette advertising. This study addressed this gap through two experiments. In Experiment One, adult traditional cigarette smokers (n = 41) and non-smokers (n = 41) answered questions about e-cigarette and neutral advertising images. The 40 e-cigarette advertising images that most increased desire to use the product were matched to 40 neutral advertising images with similar content. In Experiment Two, the 80 advertising images selected in Experiment One were presented to adolescents (n = 30) during an functional magnetic resonance imaging brain scan. There was a range of traditional cigarette smoking across the sample with some adolescents engaging in daily smoking and others who had never smoked. Adolescents self-reported that viewing the e-cigarette advertising images increased their desire to smoke. Additionally, all participants regardless of smoking statuses showed significantly greater brain activation to e-cigarette advertisements in areas associated with cognitive control (left middle frontal gyrus), reward (right medial frontal gyrus), visual processing/attention (left lingual gyrus/fusiform gyrus, right inferior parietal lobule, left posterior cingulate, left angular gyrus) and memory (right parahippocampus, left insula). Further, an exploratory analysis showed that compared with age-matched non-smokers (n = 7), adolescent smokers (n = 7) displayed significantly greater neural activation to e-cigarette advertising images in the left inferior temporal gyrus/fusiform gyrus, compared with their responses to neutral advertising images. Overall, participants' brain responses to e-cigarette advertisements suggest a need to further investigate the long-run impact of e-cigarette advertising on adolescents. © 2017 Society for the Study of Addiction.

Given the lack of regulation on marketing of electronic cigarettes (e-cigarettes) in the U.S. and the increasing exchange of e-cigarette-related information online, it is critical to understand how e-cigarette companies market e-cigarettes and how the public engages with e-cigarette information. Results are from a systematic review of peer-reviewed literature on e-cigarettes via a PubMed search through June 1, 2017. Search terms included: "e-cigarette*" OR "electronic cigarette" OR "electronic cigarettes" OR "electronic nicotine delivery" OR "vape" OR "vaping." Experimental studies, quasi-experimental studies, observational studies, qualitative studies, and mixed methods studies providing empirical findings on e-cigarette marketing and communication (i.e., non-marketing communication in the public) were included. One hundred twenty-four publications on e-cigarette marketing and communication were identified. They covered topics including e-cigarette advertisement claims/promotions and exposure/receptivity, the effect of e-cigarette advertisements on e-cigarette and cigarette use, public engagement with e-cigarette information, and the public's portrayal of e-cigarettes. Studies show increases in e-cigarette marketing expenditures and online engagement through social media over time, that e-cigarettes are often framed as an alternative to combustible cigarettes, and that e-cigarette advertisement exposure may be associated with e-cigarette trial in adolescents and young adults. Few studies examine the effects of e-cigarette marketing on perceptions and e-cigarette and cigarette use. Evidence suggests that exposure to e-cigarette advertisements affects perceptions and trial of e-cigarettes, but there is no evidence that exposure affects cigarette use. No studies examined how exposure to e-cigarette communication, particularly misleading or inaccurate information, impacts e-cigarette and tobacco use behaviors. The present article provides a comprehensive review of e-cigarette

This study models independent associations of state or local strong clean indoor air laws and cigarette prices with current smoker status and consumption in a multilevel framework, including interactions with educational attainment, household income and race/ethnicity and the relationships of these policies to vulnerabilities in smoking behavior. Cross sectional survey data are employed from the February 2002 panel of the Tobacco Use Supplement of the Current Population Survey (54,024 individuals representing the US population aged 15-80). Non-linear relationships between both outcome variables and the predictors were modeled. Independent associations of strong clean indoor air laws were found for current smoker status (OR 0.66), and consumption among current smokers (-2.36 cigarettes/day). Cigarette price was found to have independent associations with both outcomes, an effect that saturated at higher prices. The odds ratio for smoking for the highest versus lowest price over the range where there was a price effect was 0.83. Average consumption declined (-1.16 cigarettes/day) over the range of effect of price on consumption. Neither policy varied in its effect by educational attainment, or household income. The association of cigarette price with reduced smoking participation and consumption was not found to vary with race/ethnicity. Population vulnerability in consumption appears to be structured by non-white race categories, but not at the state and county levels at which the policies we studied were enacted. Clean indoor air laws and price increases appear to benefit all socio-economic and race/ethnic groups in our study equally in terms of reducing smoking participation and consumption.

Research indicates that electronic cigarette (e-cigarette) use (vaping) among adolescents is associated with the initiation and progression of combustible cigarette smoking. The reasons for this association are unknown. To evaluate whether use of e-cigarettes with higher nicotine concentrations is associated with subsequent increases in the frequency and intensity of combustible cigarette smoking and vaping. In this prospective cohort study involving students from 10 high schools in the Los Angeles, California, metropolitan area, surveys were administered during 10th grade in the spring (baseline) and 11th grade in the fall (6-month follow-up) of 2015 to students who reported using e-cigarettes within the past 30 days and the nicotine concentration level they used at baseline. Self-report of baseline e-cigarette nicotine concentration of none (0 mg/mL), low (1-5 mg/mL), medium (6-17 mg/mL), or high (≥18 mg/mL) typically used during the past 30 days. Frequency of combustible cigarette smoking and e-cigarette use within the past 30 days (0 days [none], 1-2 days [infrequent], or ≥3 days [frequent]) and daily intensity of smoking and vaping (number of cigarettes smoked per day, number of vaping episodes per day, and number of puffs per vaping episode) at the 6-month follow-up. The analytic sample included 181 students (96 boys [53.0%] and 85 girls [47.0%]; mean [SD] age, 16.1 [0.4] years). Each successive increase in nicotine concentration (none to low, low to medium, and medium to high) vaped was associated with a 2.26 (95% CI, 1.28-3.98) increase in the odds of frequent (vs no) smoking and a 1.65 (95% CI, 1.09-2.51) increase in the odds of frequent (vs no) vaping at follow-up after adjustment for baseline frequency of smoking and vaping and other relevant covariates. Use of e-cigarettes with high (vs no) nicotine concentration was associated with a greater number of cigarettes smoked per day at follow-up (adjusted rate ratio [RR], 7.03; 95% CI, 6.11-7.95). An

Since market liberalization in 1987, the Taiwan Tobacco and Wine Monopoly Bureau (TTWMB) annual statistics indicate that both the demand for imported cigarettes as well as the number of seized smuggled packs have increased with an average revenue loss of NT dollars 4942 million over the past 15 years. The NT dollars 10 average increase in cigarette prices after Taiwan entered the World Trade Organization (WTO) and the implementation of the Tobacco and Alcohol Tax Law in 2002 are forcing policy makers to examine smuggling even more closely. This study evaluates factors that affect an individual smoker's decision to purchase smuggled cigarettes, particularly when faced with higher prices. 437 male smokers of imported cigarettes were drawn from a national interview survey on cigarette consumption, which the Division of Health Policy Research at the National Health Research Institutes conducted during the year 2000. Multiple logistic regression models were used to analyse the behaviour of purchasing smuggled cigarettes with respect to demographic factors, economic factors, smoking behaviour, and other variables. Cigarette price was the driving factor most closely linked to the purchase of smuggled cigarettes--a 1% increase in cigarette price raised the likelihood of purchasing smuggled cigarettes at least 2.60 times (95% confidence interval (CI) 1.08 to 6.26). Smokers who spent more than NT 1000/month dollars on cigarettes were twice as likely to purchase smuggled cigarettes as those who spent less than NT 1000 dollars (odds ratio (OR) 2.34, 95% CI 1.48 to 3.70). Betel nut chewers were more likely to purchase smuggled cigarettes (OR 1.80, 95% CI 1.09 to 2.90). Smokers who opposed cigarette taxation policy were 1.69 times more likely to buy smuggled cigarettes. Personal income was not significantly associated with smuggled cigarettes purchases. This study evaluates what causes smokers to purchase smuggled cigarettes. We have determined that cigarette price is the most

To review the available evidence evaluating the abuse liability, topography, subjective effects, craving and withdrawal suppression associated with e-cigarette use in order to identify information gaps and provide recommendations for future research. Literature searches were conducted between October 2012 and January 2014 using five electronic databases. Studies were included in this review if they were peer-reviewed scientific journal articles evaluating clinical laboratory studies, national surveys or content analyses. A total of 15 peer-reviewed articles regarding behavioural use and effects of e-cigarettes published between 2010 and 2014 were included in this review. Abuse liability studies are limited in their generalisability. Topography (consumption behaviour) studies found that, compared with traditional cigarettes, e-cigarette average puff duration was significantly longer, and e-cigarette use required stronger suction. Data on e-cigarette subjective effects (such as anxiety, restlessness, concentration, alertness and satisfaction) and withdrawal suppression are limited and inconsistent. In general, study data should be interpreted with caution, given limitations associated with comparisons of novel and usual products, as well as the possible effects associated with subjects' previous experience/inexperience with e-cigarettes. Currently, very limited information is available on abuse liability, topography and subjective effects of e-cigarettes. Opportunities to examine extended e-cigarette use in a variety of settings with experienced e-cigarette users would help to more fully assess topography as well as behavioural and subjective outcomes. In addition, assessment of 'real-world' use, including amount and timing of use and responses to use, would clarify behavioural profiles and potential adverse health effects.

In recent years, electronic tobacco (e-cigarette/vaping) use among young adults has grown exponentially. Given past research linking obesity and cigarette smoking, assessing whether this relationship extends to electronic tobacco use is warranted. The current study examined weight status as a correlate of substance use patterns reflecting electronic tobacco use. Survey data were collected from a convenience sample of 452 (59% female) undergraduates attending a large, public university during the 2015-2016 academic year. Latent class analysis (LCA) was conducted to identify substance use classes and examine weight status as a covariate of class membership. LCA analyses identified 4 classes: High Substance Use (19%), Risky Alcohol Use (14%), Cigarette/Electronic Tobacco Use (17%), and Low Substance Use (50%). Both obesity status and greater deviation from one's group body mass index (BMI) norm were associated with a higher likelihood of belonging to the Cigarette/Electronic Tobacco Use class. Findings suggest that electronic tobacco use may fit well into previously established relationships between higher weight status and tobacco use. Future research should examine the longitudinal processes and pathways underlying the relationship between weight status and electronic tobacco use.

Cigarette purchasing patterns may be linked with greater readiness to make a quit attempt and more quit attempts among domiciled samples. However, little is known about the cigarette purchasing patterns of homeless smokers or their potential relations to quitting intention and behaviors. This study redressed this gap among a convenience sample of homeless adult smokers from a large shelter in Dallas, Texas. Participants (N = 207; Mage = 43; 71.5% male) smoked ≥100 cigarettes over the lifetime and endorsed current daily smoking. Variables assessed included cigarette dependence (time to first cigarette of the day), monthly income, quantity of cigarettes most recently purchased, average money spent on cigarettes weekly, readiness/motivation to quit smoking, and the number intentional quit attempts lasting ≥24h in the past year. Regression analyses were conducted to characterize associations of cigarette purchasing patterns with readiness to quit and quit attempts controlling for sex, age, cigarette dependence, and income. Most participants purchased cigarettes by the pack (61.4%), and more than half the sample spent ≤$20 on cigarettes per week. Results indicated that spending less money per week on cigarettes was associated with greater readiness to quit (P = .016), even when controlling for income, cigarette dependence, and other covariates. Stratified analyses indicated that this association was significant only for homeless smokers reporting no regular monthly income. Homeless daily smokers with no reported income who spend little money on cigarettes may make particularly apt targets for cessation interventions due to potential associations with quitting motivation. Adults who are homeless smoke at greater rates and quit at lower rates than domiciled adults, leading to significant smoking-related health disparities among this group. Findings suggest that cigarette purchasing patterns are linked with readiness to quit smoking among smokers who are homeless

Very little is known about how e-cigarette marketing is being perceived by youth, and the potential effect it will have on youth vaping and smoking behaviors. This limits the ability to identify youth-focused marketing efforts and to design effective policies for the regulation of e-cigarette marketing content and placement. A sample of 417 nonsmoking youth (mean age = 15, SD = 1.3) were randomly assigned to either view four e-cigarette ads with low youth appeal, four e-cigarette ads with high youth appeal or four control ads. After exposure, participants completed covert and overt measurements of e-cigarette and tobacco cigarette attitudes and susceptibility to use. Youth in an e-cigarette ad condition were more likely to select an e-cigarette item in a product choice task compared to control, and had more positive e-cigarette beliefs. Contrary to hypotheses, youth in the low youth appeal condition reported greater susceptibility to trying e-cigarettes and tobacco cigarettes compared to control. Exposure to any e-cigarette advertising may play a role in teens' decision to initiate e-cigarette and tobacco cigarette use. As the Food and Drug Administration now has regulatory authority over the marketing of e-cigarettes, regulations on e-cigarette advertising are suggested. Teens are increasingly being exposed to e-cigarette advertising, and many places are considering e-cigarette regulations, yet we know very little about how e-cigarette advertisements might influence youth tobacco use. This study utilized a novel dataset of e-cigarette ads coded for youth appeal and presented them to a sample of 417 nonsmoking teens in a randomized controlled design to test the effect of features on youth susceptibility to initiating e-cigarette and tobacco cigarette use. The findings inform evidence-based recommendations for regulating the marketing of e-cigarettes. © The Author 2017.

Full Text Available The aim of this study was to determine if 31 women with cervical dysplasia and associated conditions exacerbated by smoking would be successful substituting cigarettes with their choice of either nicotine replacement therapy (NRT or electronic cigarettes (EC. Women received motivational interviewing and tried both NRT and ECs, choosing one method to use during a six-week intervention period. Daily cigarette consumption was measured at baseline, six, and 12 weeks, with differences analyzed by the Wilcoxon signed-rank test. Study analysis consisted only of women choosing to use ECs (29/31, as only two chose NRT. At the 12-week follow-up, the seven day point prevalence abstinence from smoking was 28.6%, and the median number of cigarettes smoked daily decreased from 18.5 to 5.5 (p < 0.0001. The median number of e-cigarette cartridges used dropped from 21 at the six-week follow-up to 12.5 at the 12-week follow-up. After initiating EC use, women at risk for cervical cancer were able to either quit smoking or reduce the number of cigarettes smoked per day. Although a controlled trial with a larger sample size is needed to confirm these initial results, this study suggests that using ECs during quit attempts may reduce cigarette consumption.

Tobacco and cannabis are highly co-morbid in the general population and in patients with schizophrenia. Given the putative causal mechanisms facilitating co-use, it is important to determine how cannabis cessation may influence concurrent tobacco use. Using a 28-day cannabis abstinence paradigm, we prospectively examined changes in tobacco consumption in patients with schizophrenia and controls with cannabis dependence and daily cigarette use. Cannabis dependent patients with schizophrenia (n = 19) and controls (n = 20) completed the study with abstinence rates of 42% and 55%, respectively. Participants completed measures of substance use, withdrawal, and clinical symptoms weekly. Urine samples were collected twice weekly to biochemically verify abstinence. Patients reported a greater increase in cigarettes smoked per day (CPD) on Day 7 relative to baseline (2.97 cigarette increase for abstinent subgroup, p cannabis use related to greater increases in CPD relative to baseline in the patient subsample (simple slope = -2.31, p = .05), but by Day 28, CPD returned to baseline levels independent of cannabis use. CPD changes were unrelated to cannabis withdrawal. Results were similar for changes in caffeine consumption, but not for alcohol. Findings suggest transient tobacco substitution for cannabis in patients with schizophrenia. This provides further support for a strong association between cannabis and tobacco in schizophrenia. Future studies should focus on targeting underlying mechanisms that promote co-use to better address potential changes in concurrent substance use during treatment interventions.

(1) Compare social norms and perceived peer use between college student cigarette, e-cigarette, and/or hookah users and nonusers; and (2) determine variables associated with social influences. Undergraduate students attending a large university in the Southeast United States (N = 511). An April 2013 online survey assessed use of 3 types of tobacco, social norms, perception of peer use, number of smokers in life, exposure to secondhand smoke, and demographic characteristics. Participants indicated greater acceptance of emerging tobacco products than for cigarettes and consistently overestimated the percent of peers who use various tobacco products. Males and current users had higher social norm scores for all 3 forms of tobacco. To counter marketing of alternative tobacco products, education about the dangers of their use needs to be implemented across college campuses as part of a comprehensive tobacco control strategy that also includes tobacco-free campus policies.

Although cigarette smoking and alcohol drinking increase the risk of several cancers and certain components of cigarette smoke and alcohol can penetrate the blood-brain barrier, it remains unclear whether these exposures influence the risk of glioma. We examined the associations between cigarette smoking, alcohol intake, and risk of glioma in the National Institutes of Health-AARP Diet and Health Study, a prospective study of 477,095 US men and women ages 50-71 years at baseline. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using models with age as the time metric and adjusted for sex, race/ethnicity, education, and marital status. During a median 10.5 person-years of follow-up, 492 men and 212 women were diagnosed with first primary glioma. Among men, current, heavier smoking was associated with a reduced risk of glioma compared with never smoking, but this was based on only nine cases. No associations were observed between smoking behaviours and glioma risk in women. Greater alcohol consumption was associated with a decreased risk of glioma, particularly among men (>2 drinks per day vs Smoking and alcohol drinking do not appear to increase the risk of glioma.

Full Text Available E-cigarettes and other non-cigarette tobacco products are increasingly popular among youth. Little is known to inform public health efforts to reduce youth use. We examined psychosocial correlates of single and multiple tobacco product use among youth e-cigarette users. Data were from the 2014 Florida Youth Tobacco Survey (N = 69,923, a representative sample of Florida middle and high school students. Associations between combinations of e-cigarette, cigarette and other tobacco product (OTP use and psychosocial variables were examined using multinomial logistic regression with an analytic sample of N = 2756. Most e-cigarette-using youth used at least one other product (81%. Perceiving cigarettes as easy to quit was significantly associated with greater likelihood of combined e-cigarette/OTP use (relative risk ratio (RRR = 2.51, p < 0.001 and combined e-cigarette/cigarette/OTP use (RRR = 3.20, p < 0.0001. Thinking you will be smoking cigarettes in 5 years was associated with product combinations that include cigarettes. Tobacco company marketing receptivity was associated with multiple product user types. Given that specific psychosocial factors put youth at risk for concurrent use of e-cigarettes with tobacco products, public health efforts should address polytobacco use specifically, instead of individual product use. Youth perceptions about the ease of quitting cigarettes, intentions to continue smoking cigarettes and receptivity to tobacco company marketing are promising areas for messaging aimed at reducing e-cigarette polytobacco product use.

Litt, Mark D; Duffy, Valerie; Oncken, Cheryl

2016-11-01

The present study examined the influence of flavouring on the smoking and vaping behaviour of cigarette smokers asked to adopt e-cigarettes for a period of 6 weeks. Participants were 88 current male and female smokers with no intention to stop smoking, but who agreed to substitute e-cigarettes for their current cigarettes. On intake, participants were administered tests of taste and smell for e-cigarettes flavoured with tobacco, menthol, cherry and chocolate, and were given a refillable e-cigarette of their preferred flavour or a control flavour. Participants completed daily logs of cigarette and e-cigarette use and were followed each week. Analyses over days indicated that, during the 6-week e-cigarette period, cigarette smoking rates dropped from an average of about 16 to about 7 cigarettes/day. e-Cigarette flavour had a significant effect such that the largest drop in cigarette smoking occurred among those assigned menthol e-cigarettes, and the smallest drop in smoking occurred among those assigned chocolate and cherry flavours. e-Cigarette vaping rates also differed significantly by flavour assigned, with the highest vaping rates for tobacco- and cherry-flavoured e-cigarettes, and the lowest rates for those assigned to chocolate. The findings suggest that adoption of e-cigarettes in smokers may influence smoking rates and that e-cigarette flavourings can moderate this effect. e-Cigarette vaping rates are also influenced by flavourings. These findings may have implications for the utility of e-cigarettes as a nicotine replacement device and for the regulation of flavourings in e-cigarettes for harm reduction.

Cigarette Fires Involving Upholstered Furniture in Residences: The Role that Smokers, Smoker Behavior, and Fire Standard Compliant Cigarettes Play

Science.gov (United States)

Butry, David T.; Thomas, Douglas S.

2017-01-01

Residential structure fires pose a significant risk to life and property. A major source of these fires is the ignition of upholstered furniture by cigarettes. It has long been established that cigarettes and other lighted tobacco products could ignite upholstered furniture and were a leading cause of fire deaths in residences. In recent years, states have adopted fire standard compliant cigarettes (‘FSC cigarettes’) that are made with a wrapping paper that contains regularly spaced bands, which increases the likelihood of self-extinguishment. This paper measures the effectiveness of FSC cigarettes on the number of residential fires involving upholstered furniture, and the resulting fatalities, injuries, and extent of flame spread, while accounting for the under-reporting of fire incidents. In total, four models were estimated using fire department data from 2002 to 2011. The results provide evidence that FSC cigarettes, on average, reduced the number of residential fires by 45 %, reduced fatalities by 23 %, and extent of flame spread by 27 % in 2011. No effect on injuries was found. Within each state, effectiveness is moderated by the number of smokers and their consumption patterns. In general, FSC cigarettes are more effective in places with a large smoking population who engage in heavier smoking. There is a very limited effect on the lightest of smokers, suggesting behavioral differences between heavy and light smokers that influence fire risk. PMID:28751788

Estimating Demand and Cross-Price Elasticity for Very Low Nicotine Content (VLNC) Cigarettes Using a Simulated Demand Task.

2017-03-03

Very Low Nicotine Content (VLNC) cigarettes might be useful as part of a tobacco control strategy, but relatively little is known about their acceptability as substitutes for regular cigarettes. We compared subjective effects and demand for regular cigarettes and Very Low Nicotine Content (VLNC) cigarettes, and estimated cross-price elasticity for VLNC cigarettes, using simulated demand tasks. 40 New Zealand smokers sampled a VLNC cigarette and completed Cigarette Purchase Tasks to indicate their demand for regular cigarettes and VLNC cigarettes at a range of prices, and a cross-price task indicating how many regular cigarettes and VLNC cigarettes they would purchase at 0.5x, 1x, and 2x the current market price for regular cigarettes, assuming the price of VLNC cigarettes remained constant. They also rated the subjective effects of the VLNC cigarette and their usual-brand regular cigarettes. Cross-price elasticity for VLNC cigarettes was estimated as 0.24 and was significantly positive, indicating that VLNC cigarettes are partially substitutable for regular cigarettes. VLNC cigarettes were rated as less satisfying and psychologically rewarding than regular cigarettes, but this was unrelated to demand or substitutability. VLNC cigarettes are potentially substitutable for regular cigarettes. Their availability may reduce tobacco consumption, nicotine intake and addiction; making it easier for smokers to quit. VLNC cigarettes share the behavioural and sensory components of smoking whilst delivering negligible levels of nicotine. Although smokers rated VLNCs as less satisfying than regular cigarettes, smokers said they would increase their consumption of VLNCs as the price of regular cigarettes increased, if VLNCs were available at a lower price. This suggests that VLNCs are partially substitutable for regular cigarettes. VLNCs can be part of an effective tobacco control strategy, by reducing nicotine dependence and improving health and financial outcomes for smokers

Our goal was to measure the cross-price elasticity of electronic cigarettes (e-cigarettes) and simulated demand for tobacco cigarettes both in the presence and absence of e-cigarette availability. A sample of New Zealand smokers (N = 210) completed a Cigarette Purchase Task to indicate their demand for tobacco at a range of prices. They sampled an e-cigarette and rated it and their own-brand tobacco for favorability, and indicated how many e-cigarettes and regular cigarettes they would purchase at 0.5×, 1×, and 2× the current market price for regular cigarettes, assuming that the price of e-cigarettes remained constant. Cross-price elasticity for e-cigarettes was estimated as 0.16, and was significantly positive, indicating that e-cigarettes were partially substitutable for regular cigarettes. Simulated demand for regular cigarettes at current market prices decreased by 42.8% when e-cigarettes were available, and e-cigarettes were rated 81% as favorably as own-brand tobacco. However when cigarettes cost 2× the current market price, significantly more smokers said they would quit (50.2%) if e-cigarettes were not available than if they were available (30.0%). Results show that e-cigarettes are potentially substitutable for regular cigarettes and their availability will reduce tobacco consumption. However, e-cigarettes may discourage smokers from quitting entirely as cigarette price increases, so policy makers should consider maintaining a constant relative price differential between e-cigarettes and tobacco cigarettes. © The Author 2014.

The electronic cigarette (e-cigarette) market is maturing into a billion-dollar industry. Expansion includes new channels of access not sufficiently assessed, including Internet sales of e-cigarettes. This study identifies unique e-cigarette Internet vendor characteristics, including geographic location, promotional strategies, use of social networking, presence/absence of age verification, and consumer warning representation. We performed structured Internet search engine queries and used inclusion/exclusion criteria to identify e-cigarette vendors. We then conducted content analysis of characteristics of interest. Our examination yielded 57 e-cigarette Internet vendors including 54.4% (n=31) that sold exclusively online. The vast majority of websites (96.5%, n=55) were located in the U.S. Vendors used a variety of sales promotion strategies to market e-cigarettes including 70.2% (n=40) that used more than one social network service (SNS) and 42.1% (n=24) that used more than one promotional sales strategies. Most vendors (68.4%, n=39) displayed one or more health warnings on their website, but often displayed them in smaller font or in their terms and conditions. Additionally, 35.1% (n=20) of vendors did not have any detectable age verification process. E-cigarette Internet vendors are actively engaged in various promotional activities to increase the appeal and presence of their products online. In the absence of FDA regulations specific to the Internet, the e-cigarette e-commerce marketplace is likely to grow. This digital environment poses unique challenges requiring targeted policy-making including robust online age verification, monitoring of SNS marketing, and greater scrutiny of certain forms of marketing promotional practices.

Exposure to cigarette smoke is known to result in impaired host defense responses and immune suppressive effects. However, the effects of new and emerging tobacco products, such as e-cigarettes, on the immune status of the respiratory epithelium are largely unknown. We conducted a clinical study collecting superficial nasal scrape biopsies, nasal lavage, urine, and serum from nonsmokers, cigarette smokers, and e-cigarette users and assessed them for changes in immune gene expression profiles. Smoking status was determined based on a smoking history and a 3- to 4-wk smoking diary and confirmed using serum cotinine and urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) levels. Total RNA from nasal scrape biopsies was analyzed using the nCounter Human Immunology v2 Expression panel. Smoking cigarettes or vaping e-cigarettes resulted in decreased expression of immune-related genes. All genes with decreased expression in cigarette smokers (n = 53) were also decreased in e-cigarette smokers. Additionally, vaping e-cigarettes was associated with suppression of a large number of unique genes (n = 305). Furthermore, the e-cigarette users showed a greater suppression of genes common with those changed in cigarette smokers. This was particularly apparent for suppressed expression of transcription factors, such as EGR1, which was functionally associated with decreased expression of 5 target genes in cigarette smokers and 18 target genes in e-cigarette users. Taken together, these data indicate that vaping e-cigarettes is associated with decreased expression of a large number of immune-related genes, which are consistent with immune suppression at the level of the nasal mucosa.

Although marijuana and tobacco are commonly coused, the nature of their relationship has not been fully elucidated. Behavioral economics has characterized the relationship between concurrently available commodities but has not been applied to marijuana and tobacco couse. U.S. adults ≥18 years who coused marijuana and tobacco cigarettes were recruited via Mechanical Turk, a crowdsourcing service by Amazon. Participants (N = 82) completed online purchasing tasks assessing hypothetical marijuana or tobacco cigarette puff consumption across a range of per-puff prices; 2 single-commodity tasks assessed these when only 1 commodity was available, and 2 cross-commodity tasks assessed these in the presence of a concurrently available fixed-price commodity. Purchasing tasks generated measures of demand elasticity, that is, sensitivity of consumption to prices. In single-commodity tasks, consumption of tobacco cigarette puffs (elasticity of demand: α = 0.0075; 95% confidence interval [0.0066, 0.0085], R² = 0.72) and of marijuana puffs (α = .0044; 95% confidence interval [0.0038, 0.0049], R² = 0.71) declined significantly with increases in price per puff. In cross-commodity tasks when both tobacco cigarette puffs and marijuana puffs were available, demand for 1 commodity was independent of price increases in the other commodity (ps > .05). Results revealed that, in this small sample, marijuana and tobacco cigarettes did not substitute for each other and did not complement each other; instead, they were independent of each other. These preliminary results can inform future studies assessing the economic relationship between tobacco and marijuana in the quickly changing policy climate in the United States.

Liber, Alex C.; Ross, Hana; Omar, Maizurah; Chaloupka, Frank J.

2015-01-01

Objectives Study the effects of the 2011 Malaysian minimum price law (MPL) on prices of licit and illicit cigarette brands. Identify barriers to the MPL achieving positive public health effects. Methods The International Tobacco Control Project's Southeast Asia survey collected information on Malaysian smokers' cigarette purchases (n=7,520) in five survey waves between 2005 and 2012. Consumption-weighted comparisons of proportions tests and adjusted Wald tests were used to evaluate changes over time in violation rates of the inflation-adjusted MPL, the proportion of illicit cigarette purchases, and mean prices. Results After the passage of the MPL, the proportion of licit brand cigarette purchases that were below the inflation-adjusted 2011 minimum price level fell substantially (before 3.9%, after 1.8%, p=0.002), while violation of the MPL for illicit brand cigarette purchases was unchanged (before 89.8%, after 91.9%, p=0.496). At the same time, the mean real price of licit cigarettes rose (p=0.006) while the mean real price of illicit cigarettes remained unchanged (p=0.134). The proportion of illicit cigarette purchases rose as well (before 13.4%, after 16.5%, p=0.041). Discussion The MPL appears not to have meaningfully changed cigarette prices in Malaysia, as licit brand prices remained well above and illicit brand prices remained well below the minimum price level before and after MPL's implementation. The increasing proportion of illicit cigarettes on the market may have undermined any positive health effects of the Malaysian MPL. The illicit cigarette trade must be addressed before a full evaluation of the Malaysian MPL's impact on public health can take place. The authors encourage the continued use of specific excise tax increases to reliably increase the price and decrease the consumption of cigarettes in Malaysia and elsewhere. PMID:25808666

Objective Following cigarette excise tax increases, smokers may use cigarette price minimization strategies to continue their usual cigarette consumption rather than reducing consumption or quitting. This reduces the public health benefits of the tax increase. This paper estimates the price reductions for a wide-range of strategies, compensating for overlapping strategies. Method We performed regression analysis on the 2009–2010 National Adult Tobacco Survey (N = 13,394) to explore price reductions that smokers in the United States obtained from purchasing cigarettes. We examined five cigarette price minimization strategies: 1) purchasing discount brand cigarettes, 2) using price promotions, 3) purchasing cartons, 4) purchasing on Indian reservations, and 5) purchasing online. Price reductions from these strategies were estimated jointly to compensate for overlapping strategies. Results Each strategy provided price reductions between 26 and 99 cents per pack. Combined price reductions were possible. Additionally, price promotions were used with regular brands to obtain larger price reductions than when price promotions were used with generic brands. Conclusion Smokers can realize large price reductions from price minimization strategies, and there are many strategies available. Policymakers and public health officials should be aware of the extent that these strategies can reduce cigarette prices. PMID:24594102

Full Text Available Abstract The purpose of this cross-sectional study was to examine the impact of personality factors (neuroticism, extraversion, openness, agreeableness, and conscientiousness, cognitive factors (sense of coherence and self-efficacy, coping resources (family and friend social support and demographic factors (gender and ethnicity on cigarette smoking behaviors (initiation, frequency, and amount of cigarette smoking among college students. A total of 161 U.S. college students, aged 18–26, who enrolled in an introductory psychology course completed self-report questionnaires. The majority of the students had tried smoking (55%; among those who had tried, 42% were current smokers. The majority (77% who had smoked a whole cigarette did so at age 16 years or younger. Students who reported lower levels of conscientiousness and self-efficacy had a greater likelihood to had tried cigarette smoking. Also, students who had lower levels of self-efficacy reported smoking more frequently and greater quantities of cigarettes than students with higher levels of self-efficacy. Self-efficacy was the most significant predictor of smoking behaviors. Health promotion programs focused on self-efficacy may be an effective tool for reducing the initiation, frequency, and amount of cigarette smoking among college students.

Measuring changes in the illicit cigarette market using government revenue data: the example of South Africa.

Science.gov (United States)

van Walbeek, Corné

2014-05-01

The tobacco industry claims that illicit trade in cigarettes has increased sharply since the 1990s and that government has lost substantial tax revenue. (1) To determine whether cigarette excise tax revenue has been below budget in recent years, compared with previous decades. (2) To determine trends in the size of the illicit market since 1995. For (1), mean percentage errors and root mean square percentage errors were calculated for budget revenue deviation for three products (cigarettes, beer and spirits), for various subperiods. For (2), predicted changes in total consumption, using actual cigarette price and GDP changes and previously published price and income elasticity estimates, were calculated and compared with changes in tax-paid consumption. Cigarette excise revenues were 0.7% below budget for 2000-2012 on average, compared with 3.0% below budget for beer and 4.7% below budget for spirits. There is no evidence that illicit trade in cigarettes in South Africa increased between 2002 and 2009. There is a substantial increase in illicit trade in 2010, probably peaking in 2011. In 2012 tax-paid consumption of cigarettes increased 2.6%, implying that the illicit market share decreased an estimated 0.6 percentage points. Other than in 2010, there is no evidence that illicit trade is significantly undermining government revenue. Claims that illicit trade has consistently increased over the past 15 years, and has continued its sharp increase since 2010, are not supported. Published by the BMJ Publishing Group Limited.

Objective To examine the relationship between tobacco cigarette brand recognition, and e-cigarette use in adolescents. Design Cross-sectional observational study. Setting High schools in Scotland. Participants Questionnaires were administered to pupils in Secondary 2 (S2 mean age: 14.0 years) and Secondary 4 (S4 mean age: 15.9 years) across 4 communities in Scotland. An 86% response rate with a total sample of 1404 pupils was achieved. Main outcome measures Self-reported previous use of e-cigarettes and self-reported intention to try e-cigarettes in the next 6 months. Results 75% (1029/1377) of respondents had heard of e-cigarettes (69.5% S2, 81.1% S4), and of these, 17.3% (10.6% S2, 24.3% S4 n=1020) had ever tried an e-cigarette. 6.8% (3.7% S2, 10.0% S4 n=1019) reported that they intended to try an e-cigarette in the next 6 months. Recognition of more cigarette brands was associated with greater probability of previous e-cigarette use (OR 1.20, 99% CI 1.05 to 1.38) as was having a best friend who smoked (OR 3.17, 99% CI 1.42 to 7.09). Intention to try e-cigarettes was related to higher cigarette brand recognition (OR 1.41, 99% CI 1.07 to 1.87), hanging around in the street or park more than once a week (OR 3.78, 99% CI 1.93 to 7.39) and living in areas of high tobacco retail density (OR 1.20, 99% CI 1.08 to 1.34). Never having smoked was a protective factor for both future intention to try, and past e-cigarette use (OR 0.07, 99% CI 0.02 to 0.25; and OR 0.10, 99% CI 0.07 to 0.16, respectively). Conclusions Higher cigarette brand recognition was associated with increased probability of previous use and of intention to use e-cigarettes. The impact of tobacco control measures such as restricting point-of-sale displays on the uptake of e-cigarettes in young people should be evaluated. PMID:26908512

Comparing projected impacts of cigarette floor price and excise tax policies on socioeconomic disparities in smoking.

Golden, Shelley D; Farrelly, Matthew C; Luke, Douglas A; Ribisl, Kurt M

2016-10-01

About half of all US states have cigarette minimum price laws (MPLs) that require a per cent mark-up on prices, but research suggests they may not be very effective in raising prices. An alternative type of MPL sets a floor price below which packs cannot be sold, and may be more promising. This new type of MPL policy has only been implemented in 1 city, therefore its benefits relative to excise taxes is difficult to assess. We constructed a set of possible state floor price MPL options, and matched them to possible state excise tax hikes designed to produce similar average price increases. Using self-reported price and cigarette consumption data from 23 521 participants in the 2010-2011 Tobacco Use Supplement of the Current Population Survey, we projected changes in pack prices and cigarette consumption following implementation of each paired MPL and tax option, for lower and higher income groups. We project that state MPLs set at the average reported pack price would raise prices by $0.33 and reduce cigarette consumption by about 4%; a tax with a similar average price effect would reduce consumption by 2.3%. MPLs and taxes that raise average prices by more than $2.00 would reduce consumption by 15.9% and 13.5%, respectively. In all models, we project that MPLs will reduce income-based smoking disparities more than their comparable excise taxes. Floor price cigarette MPLs set at or above what consumers currently report paying could reduce both tobacco use and socioeconomic disparities in smoking.

Low Nicotine Content Descriptors Reduce Perceived Health Risks and Positive Cigarette Ratings in Participants Using Very Low Nicotine Content Cigarettes.

Understanding how smokers perceive reduced nicotine content cigarettes will be important if the FDA and global regulatory agencies implement reduced nicotine product standards for cigarettes. Prior research has shown that some smokers incorrectly believe "light" cigarettes are less harmful than regular cigarettes. Similar misunderstandings of health risk could also apply to reduced nicotine cigarettes. To date, most studies of reduced nicotine cigarettes have blinded subjects to the nicotine content. Therefore, little is known about how smokers experience reduced nicotine content cigarettes when they are aware of the reduced content, and how use may be impacted. The present study was a within-subjects experiment with 68 adult daily smokers who smoked two identical very low nicotine content Quest 3 (0.05 mg nicotine yield) cigarettes. Subjects were told that one cigarette contained "average" nicotine content, and the other contained "very low" nicotine content. After smoking each cigarette, subjects completed subjective measures about their smoking experience. Subjects rated the "very low" nicotine cigarette as less harmful to their health overall compared to the "average" nicotine cigarette; this effect held true for specific smoking-related diseases. Additionally, they rated the "very low" nicotine cigarette as having less desirable subjective effects than the "average" nicotine cigarette and predicted having greater interest in quitting smoking in the future if only the "very low" nicotine cigarette was available. Explicit knowledge of very low nicotine content changes smokers' perceptions of very low nicotine content cigarettes, resulting in reduced predicted harm, subjective ratings and predicted future use. Before a reduced nicotine product standard for cigarettes can be implemented, it is important to understand how product information impacts how smokers think about and experience very low nicotine content cigarettes. Prior research has shown that smokers

Why ban the sale of cigarettes? The case for abolition

The cigarette is the deadliest artefact in the history of human civilisation. Most of the richer countries of the globe, however, are making progress in reducing both smoking rates and overall consumption. Many different methods have been proposed to steepen this downward slope, including increased taxation, bans on advertising, promotion of cessation, and expansion of smoke-free spaces. One option that deserves more attention is the enactment of local or national bans on the sale of cigarett...

Sex-related differences in serum cotinine concentrations in daily cigarette smokers.

Self-reported use of cigarettes generally underestimates the true cigarette exposure of smokers. Serum cotinine is considered the best biomarker to evaluate tobacco exposure. This study determined whether or not there were any significant differences in serum cotinine concentrations between men and women when they reported smoking the same number of cigarettes per day. We analyzed cotinine and tobacco consumption data on 680 women and 840 men, aged 20 years or older, who smoked at least 100 cigarettes during their lifetime and were still actively smoking at the time of the National Health and Nutrition Examination Surveys (1999-2002). Overall, compared with men, women reported smoking fewer cigarettes per day (16.1 vs. 18.7, ppoverty status, the use of either menthol or regular cigarettes, and the nicotine content in cigarettes, female compared with male smokers had lower serum cotinine concentrations (difference of 117.6 nmol/L; 95% CI = 42.6-192.6, p = .003). The difference was particularly notable in moderate to heavy smokers (i.e., those who smoked more than 15 cigarettes/day). These findings indicate that significant sex-related differences exist in serum cotinine levels among smokers, which suggests that self-reports may overestimate cigarette exposure in women compared with men.

The aim of this study was to investigate the possible reduced risk of Parkinson Disease (PD) due to coffee, alcohol, and/or cigarette consumption. In addition, we explored the potential effect modification by intensity, duration and time-since-cessation of smoking on the association between cumulative pack-years of cigarette smoking (total smoking) and PD risk. Data of a hospital based case-control study was used including 444 PD patients, diagnosed between 2006 and 2011, and 876 matched controls from 5 hospitals in the Netherlands. A novel modeling method was applied to derive unbiased estimates of the potential modifying effects of smoking intensity, duration, and time-since-cessation by conditioning on total exposure. We observed no reduced risk of PD by alcohol consumption and only a weak inverse association between coffee consumption and PD risk. However, a strong inverse association of total smoking with PD risk was observed (OR=0.27 (95%CI: 0.18-0.42) for never smokers versus highest quartile of tobacco use). The observed protective effect of total smoking was significantly modified by time-since-cessation with a diminishing protective effect after cessation of smoking. No effect modification by intensity or duration of smoking was observed indicating that both intensity and duration have an equal contribution to the reduced PD risk. Understanding the dynamics of the protective effect of smoking on PD risk aids in understanding PD etiology and may contribute to strategies for prevention and treatment.

GroupA (n = 100 received 7.2 mg nicotine cartridges for 12 weeks; GroupB (n = 100, a 6-week 7.2 mg nicotine cartridges followed by a further 6-week 5.4 mg nicotine cartridges; GroupC (n = 100 received no-nicotine cartridges for 12 weeks. The study consisted of nine visits during which cig/day use and exhaled carbon monoxide (eCO levels were measured. Smoking reduction and abstinence rates were calculated. Adverse events and product preferences were also reviewed.Declines in cig/day use and eCO levels were observed at each study visits in all three study groups (p<0.001 vs baseline, with no consistent differences among study groups. Smoking reduction was documented in 22.3% and 10.3% at week-12 and week-52 respectively. Complete abstinence from tobacco smoking was documented in 10.7% and 8.7% at week-12 and week-52 respectively. A substantial decrease in adverse events from baseline was observed and withdrawal symptoms were infrequently reported during the study. Participants' perception and acceptance of the product under investigation was satisfactory.In smokers not intending to quit, the use of e-cigarettes, with or without nicotine, decreased cigarette consumption and elicited enduring tobacco

Cigarette smoking is a well-known risk factor of upper digestive diseases. Findings on alcohol's effect on these diseases are inconsistent and with the exception of its association with esophageal cancer, little is known about betel quid chewing. This study investigated the association between use of these three substances and upper digestive diseases. We collected data from 9,275 patients receiving upper endoscopies between April 2008 and December 2013. Polynomial regressions were used to analyze the association between risk factors and diseases of the esophagus, stomach and duodenum. Meta-analysis for use of these substances and esophageal diseases was also performed. Participants who simultaneously consumed cigarettes, alcohol and betel quid had a 17.28-fold risk of esophageal cancer (95% CI = 7.59-39.33), 2.99-fold risk of Barrette's esophagus (95% CI = 2.40-4.39), 1.60-fold risk of grade A-B erosive esophagitis (95% CI = 1.29-2.00), 2.00-fold risk of gastric ulcer (95% CI = 1.52-2.63), 2.12-fold risk of duodenitis (95% CI = 1.55-2.89) and 1.29-fold risk of duodenal ulcer (95% CI = 1.01-1.65). Concurrent consumption of more substances was associated with significantly higher risk of developing these diseases. Meta-analysis also revealed use of the three substances came with a high risk of esophageal diseases. In conclusions, cigarette smoking, alcohol drinking and betel quid chewing were associated with upper digestive tract diseases.

Full Text Available Abstract Background Cigarette taxation has been perceived by academics and policy-makers as one of the most effective ways of reducing the use of cigarettes. On January 1 2002, the Taiwan government imposed a New Taiwan (NT $5 per pack tax earmarked for the purpose of tobacco control. This study uses a survey collected prior to taxation to assess public attitudes toward cigarette taxation, public beliefs about the effectiveness of cigarette taxation at reducing cigarette use and public opinions about the allocation of this tax revenue. Methods Data were drawn from a national face-to-face interview on cigarette consumption in 2000. A total of 3,279 adults were aged 18 to 64 years; 49.9% of whom were male and 50.1% female, and with a smoking prevalence of 49.1% and 4.1%, respectively. The attitudes toward cigarette tax were analysed using multi-logit regressions. We analysed by logistic regression the potential changes in smoking behaviour that smokers might make in response to the five NT (New Taiwan dollar earmarked tax on cigarettes per pack. We summarized public opinions about the allocation of earmarked tax revenue using descriptive statistics. Results Current smokers (OR = 0.34 and former smokers (OR = 0.68 were less likely to support the cigarette tax than non-smokers. A favourable attitude toward the tax was positively associated with personal monthly income, especially among females. Among male smokers, the possibility of reducing/quitting smoking in response to the five-NT-dollar tax was negatively associated with the monthly expense for smoking. The two most frequently-suggested areas to receive money from the revenue collected from the earmarked tax were health education and cancer subsidy. Conclusions Smoking status and economic factors determine the attitude and potential responses of people toward the cigarette tax. Taiwan's five NT-dollar earmarked tax for cigarettes may have only a limited effect upon the reduction in cigarette

Public health concerns regarding e-cigarettes and debate on appropriate regulatory responses are focusing on the need to prevent child access to these devices. However, little is currently known about the characteristics of those young people that are accessing e-cigarettes. Using a cross-sectional survey of 14-17 year old school students in North West England (n = 16,193) we examined associations between e-cigarette access and demographics, conventional smoking behaviours, alcohol consumption, and methods of accessing cigarettes and alcohol. Access to e-cigarettes was identified through a question asking students if they had ever tried or purchased e-cigarettes. One in five participants reported having accessed e-cigarettes (19.2%). Prevalence was highest among smokers (rising to 75.8% in those smoking >5 per day), although 15.8% of teenagers that had accessed e-cigarettes had never smoked conventional cigarettes (v.13.6% being ex-smokers). E-cigarette access was independently associated with male gender, having parents/guardians that smoke and students' alcohol use. Compared with non-drinkers, teenagers that drank alcohol at least weekly and binge drank were more likely to have accessed e-cigarettes (adjusted odds ratio [AOR] 1.89, P smoking cessation. Those most likely to access e-cigarettes may already be familiar with illicit methods of accessing age-restricted substances.

We addressed the question whether 5-HTTLPR, a variable number of tandem repeats located in the 5' end of the serotonin transporter gene, is associated with smoking or alcohol consumption. Samples of DNA from 1,365 elderly women with a mean age of 69.2 years were genotyped for this polymorphism...... using a procedure, which allowed the simultaneous determination of variation in the number of repeat units and single nucleotide changes, including the A > G variation at rs25531 for discrimination between the L(A) and L(G) alleles. Qualitative and quantitative information on the women's current...... and previous consumption of cigarettes and alcohol were obtained using a questionnaire. Genotypes were classified according to allele size, that is, S and L with 14 and 16 repeat units, respectively, and on a functional basis by amalgamation of the L(G) and S alleles.

E-cigarette use has increased rapidly among U.S. adults. However, reasons for use among adults are unclear. We assessed reasons for e-cigarette use among a national sample of U.S. adults. Data were collected via online surveys among U.S. adults aged 18 or older from April through June 2014. Descriptive and multivariate regression analyses were conducted to assess reasons for e-cigarette use among 2448 current e-cigarette users, by sociodemographic characteristics and product type. Assessed reasons included cessation/health, consideration of others, convenience, cost, curiosity, flavoring, and simulation of conventional cigarettes. Among current e-cigarette users, 93% were also current cigarette smokers. The most common reasons for e-cigarette use were cessation/health (84.5%), consideration of others (71.5%), and convenience (56.7%). The prevalence of citing convenience (adjusted prevalence ratio [aPR] = 1.49) and curiosity (aPR = 1.54) as reasons for e-cigarette use were greater among current cigarette smokers than nonsmokers (P e-cigarette use among adults, and flavorings are more commonly cited by younger adults. Efforts are warranted to provide consumers with accurate information on the health effects of e-cigarettes and to ensure that flavoring and other unregulated features do not promote nicotine addiction, particularly among young adults.

To use a unique longitudinal data set to assess the association between e-cigarette use while smoking with smoking cessation attempts, cessation and substantial reduction, taking into account frequency of use and key potential confounders. Web-based survey, baseline November/December 2012, 1-year follow-up in December 2013. Great Britain. National general population sample of 4064 adult smokers, with 1759 (43%) followed-up. Main outcome measures were cessation attempt, cessation and substantial reduction (≥50% from baseline to follow-up) of cigarettes per day (CPD). In logistic regression models, cessation attempt in the last year (analysis n = 1473) and smoking status (n = 1656) at follow-up were regressed on to baseline e-cigarette use (none, non-daily, daily) while adjusting for baseline socio-demographics, dependence and nicotine replacement (NRT) use. Substantial reduction (n = 1042) was regressed on to follow-up e-cigarette use while adjusting for baseline socio-demographics and dependence and follow-up NRT use. Compared with non-use, daily e-cigarette use at baseline was associated with increased cessation attempts [odds ratio (OR) = 2.11, 95% confidence interval (CI) = 1.24-3.58, P = 0.006], but not with cessation at follow-up (OR = 0.62, 95% CI = 0.28-1.37, P = 0.24). Non-daily use was not associated with cessation attempts or cessation. Daily e-cigarette use at follow-up was associated with increased odds of substantial reduction (OR = 2.49, 95% CI = 1.14-5.45, P = 0.02), non-daily use was not. Daily use of e-cigarettes while smoking appears to be associated with subsequent increases in rates of attempting to stop smoking and reducing smoking, but not with smoking cessation. Non-daily use of e-cigarettes while smoking does not appear to be associated with cessation attempts, cessation or reduced smoking. © 2015 The Authors.

Estimate price and income elasticities of aggregate demand for cigarettes in Colombia, by controlling for structural market changes since the late 1990s, to identify policy opportunities for taxes that could improve public health and increase tax revenues. Measurement of aggregate demand for cigarettes using gross income reported on value-added tax returns submitted to Colombia's National Tax and Customs Office (DIAN is the acronym in Spanish) by the tobacco product manufacturing industry, subtracting exports. A quarterly time series was obtained for the period 1994-2014. The econometric estimation using two-stage least squares controls for price endogeneity and uses a set of dummy variables to control for structural changes in the market and in its regulation. Demand is, from a statistical standpoint, sensitive to price and to income. Price elasticity of demand is -0.78 and income elasticity is 0.61. Inelastic demand implies that it is possible, through cigarette excise taxes, to meet public health targets and increase revenues simultaneously. The results also suggest that the considerable increase in household income in Colombia in the first decade of the 21st century increased purchasing power, which, lacking an accompanying tax increase, promoted cigarette consumption, with negative effects on public health, and wasted an opportunity to increase tax revenues.

Electronic cigarettes (e-cigarettes) electrically heat and vaporize e-liquids to produce inhalable vapors. These devices are being used to inhale vapors produced by dripping e-liquids directly onto heated atomizers. The current study conducts the first evaluation of the prevalence rates and reasons for using e-cigarettes for dripping among high school students. In the spring of 2015, students from 8 Connecticut high schools ( n = 7045) completed anonymous surveys that examined tobacco use behaviors and perceptions. We assessed prevalence rates of ever using e-cigarettes for dripping, reasons for dripping, and predictors of dripping behaviors among those who reported ever use of e-cigarettes. Among 1080 ever e-cigarette users, 26.1% of students reported ever using e-cigarettes for dripping. Reasons for dripping included produced thicker clouds of vapor (63.5%), made flavors taste better (38.7%), produced a stronger throat hit (27.7%), curiosity (21.6%), and other (7.5%). Logistic regression analyses indicated that male adolescents (odds ratio [OR] = 1.64), whites (OR = 1.46), and those who had tried multiple tobacco products (OR = 1.34) and had greater past-month e-cigarette use frequency (OR = 1.07) were more likely to use dripping ( P s e-cigarettes also report using the device for dripping. Future efforts must examine the progression and toxicity of the use of e-cigarettes for dripping among youth and educate them about the potential dangers of these behaviors.

Few clinical studies involving cigarettes have provided a comprehensive picture of smoke exposure, test article characterization, and insights into sensory properties combined. The purpose of these pilot studies was to determine whether cigarettes with different levels of nicotine but similar tar levels would affect sensory experience or smoking behavior so as to significantly alter levels of selected biomarkers of exposure (BOE). In 2 confined, double-blind studies, 120 adult smokers switched from Marlboro Gold cigarettes at baseline to either 1 of 2 lower nicotine cigarettes or 1 of 2 higher nicotine cigarettes and then to the other cigarette after 5 days. Urinary excretion of exposure biomarkers (nicotine equivalents [NE], total and free 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol [NNAL], 1-hydroxypyrene, and 3-hydroxypropyl mercapturic acid) as well as carboxyhemoglobin and plasma cotinine were measured at baseline, Day 5, and Day 10. Daily cigarette consumption was monitored and sensory characteristics were rated for each cigarette. With higher nicotine yield, urine NE, urine total NNAL, and plasma cotinine increased while nonnicotine BOE decreased without changes in cigarette consumption. In contrast, with lower nicotine yield, urine NE, urine total NNAL, and plasma cotinine dropped while nonnicotine BOE and cigarettes per day increased. Higher nicotine cigarettes were rated harsher and stronger than at baseline while lower nicotine cigarettes were less strong. All 4 test cigarettes were highly disliked. These studies demonstrate that abrupt increases or decreases in nicotine and the resulting sensory changes impact BOE through changes in intensity or frequency of smoking. © The Author 2014.

It is well known that tobacco consumption is a leading cause of preventable deaths worldwide and has been linked to major diseases ranging from cancer to chronic obstructive pulmonary disease, atherosclerosis, stroke and a host of neurological/neurodegenerative disorders. In the past decade a number of alternative vaping products have hit the market, rapidly gaining consumers especially among the younger population. Electronic nicotine delivery systems or e-cigarettes have become the sought-after product due to the belief that they are much safer than traditional cigarettes. However, inadequate research and lack of regulatory guidelines for both the manufacturing process and the content of the vaping solution of the e-cigarette has become a major concern. Highly debated and unresolved questions such as whether e-cigarettes may help smokers quit and whether e-cigarettes will promote the use of nicotine among non-smokers add to the confusion of the safety of e-cigarettes. In this review article, we summarize the current understanding (and lack thereof) of the potential health impacts of e-cigarettes. We will also highlight the most recent studies (in vivo/in vitro) which seem to conflict with the broad safety claims put forward by the manufacturers. Finally, we provide potential solutions to overcome the research gap of the short and long-term health impact of e-cigarettes. Published by Elsevier Ireland Ltd.

Few studies have examined the impact of tobacco tax and price policies in China. In addition, very little is known about the differential responses to tax and price increases based on socioeconomic status in China. To estimate the conditional cigarette consumption price elasticity among adult urban smokers in China and to examine the differential responses to cigarette price increases among groups with different income and/or educational levels. Multivariate analyses employing the general estimating equations method were conducted using the first three waves of the International Tobacco Control (ITC) China Survey. Analyses based on subsample by education and income were conducted. Conditional cigarette demand price elasticity ranges from -0.12 to -0.14. No differential responses to cigarette price increase were found across education levels. The price elasticity estimates do not differ between high-income smokers and medium-income smokers. Cigarette consumption among low-income smokers did not decrease after a price increase, at least among those who continued to smoke. Relative to other low-income and middle-income countries, cigarette consumption among Chinese adult smokers is not very sensitive to changes in cigarette prices. The total impact of cigarette price increase would be larger if its impact on smoking initiation and cessation, as well as the price-reducing behaviours such as brand switching and trading down, were taken into account.

Studies suggest that exposure to televised electronic cigarette (e-cigarette) advertising contributes to the recent increase in e-cigarette use among youth. This study examines the relationship between perceptions of e-cigarette advertisements and attitudes toward and intentions to use e-cigarettes among youth who had never used e-cigarettes. In May 2014, we conducted an online survey of 5020 youth aged 13 to 17. Participants were randomly assigned to answer questions about their attitudes toward and intentions to use e-cigarettes before or after viewing e-cigarette advertisements. Perceived effectiveness (PE) of advertisements was measured after ad exposure. Ordinary least squares models were used to assess the relationship between PE and study outcomes. Among never e-cigarette users, greater PE was associated with more positive attitudes toward e-cigarettes (b = 0.74, P effective were more likely to have a positive attitude toward e-cigarettes and greater intention to try e-cigarettes in the future. Restricting televised e-cigarette advertising may reduce e-cigarette initiation among youth. Previous studies demonstrate that, among adults, PE is antecedent to actual ad effectiveness across a range of behaviors. To our knowledge, this is the first study to document the relationship between PE and advertising effectiveness among youth. It provides evidence that PE may be a useful tool to quantify the potential influence of advertising on youth-advertising that, in this case, is designed to market a consumer good that may be harmful to youth but that may also be used to develop public health campaigns. © The Author 2015.

To review the impact of electronic cigarettes (e-cigarettes) on children. Five electronic databases were searched through 31 December 2013. Studies in English that included data for children younger than 18 years of age were included. In addition, relevant data from articles identified during searches of the e-cigarette literature, relevant state survey data and paediatric voluntary adverse event reports submitted to the US Food and Drug Administration (FDA) were reviewed and included. Use of e-cigarettes by youth is increasing and is not limited to traditional cigarette smokers. Data regarding the reasons for youth e-cigarette initiation and ongoing use are limited. The effects of e-cigarette marketing and the availability of flavoured e-liquids on youth use are unknown. The abuse liability of e-cigarettes in youth is also not known. Unintentional exposures to e-cigarettes and e-liquids have been reported in children. The number of e-cigarette-related reports received by poison centres is increasing. No data are available on secondhand and thirdhand e-cigarette aerosol exposures in children. Data on the impact of e-cigarettes on children are extremely limited. The available data indicate that youth awareness is high and use is increasing rapidly. The extent to which e-cigarette use in youth will result in nicotine dependence and subsequent use of other tobacco products is unknown. e-cigarettes present risks of unintentional nicotine exposure and are potential choking hazards. A greater understanding of the impact of e-cigarettes on children is needed and will be important in the evaluation of the effects of these products on the public health.

The popularity of electronic cigarettes (e-cigarettes) is rapidly increasing in many countries. These devices are designed to imitate regular cigarettes, delivering nicotine via inhalation without combusting tobacco but currently, there is a lack of scientific evidence on the presence or absence of nicotine exposure. Such research relies on evidence from e-cigarette users urine samples. In this study, we aimed to determine the levels and compare the amount of nicotine to which e-cigarette users, cigarette smokers and passive smokers are exposed. Therefore, urine samples were collected from e-cigarette users, cigarette smokers, passive smokers, and healthy nonsmokers. The urinary cotinine levels of the subjects were determined using gas chromatography-mass spectrometry. The mean (±SD) urinary cotinine levels were determined as 1755 ± 1848 ng/g creatinine for 32 e-cigarette users, 1720 ± 1335 ng/g creatinine for 33 cigarette smokers and 81.42 ± 97.90 ng/g creatinine for 33 passive smokers. A significant difference has been found between cotinine levels of e-cigarette users and passive smokers (p e-cigarette users and cigarette smokers (p > 0.05). This is a seminal study to demonstrate the e-cigarette users are exposed to nicotine as much as cigarette smokers.

Cigarette smoking is a major risk factor for head and neck cancer (HNC). To our knowledge, low cigarette smoking (frequency of cigarette consumption was categorized as follows: never cigarette users, >0-3, >3-5, >5-10 cigarettes per day. Smoking >0-3 cigarettes per day was associated with a 50% increased risk of HNC in the study population [odds ratio (OR) = 1.52, 95% confidence interval (CI): (1.21, 1.90). Smoking >3-5 cigarettes per day was associated in each subgroup from OR = 2.01 (95% CI: 1.22, 3.31) among never alcohol drinkers to OR = 2.74 (95% CI: 2.01, 3.74) among women and in each cancer site, particularly laryngeal cancer (OR = 3.48, 95% CI: 2.40, 5.05). However, the observed increased risk of HNC for low smoking frequency was not found among smokers with smoking duration shorter than 20 years. Our results suggest a public health message that low frequency of cigarette consumption contributes to the development of HNC. However, smoking duration seems to play at least an equal or a stronger role in the development of HNC. © The Author 2015; all rights reserved.

Use of e-cigarettes has been increasing exponentially, with the primary motivation reported as smoking cessation. To understand why smokers choose e-cigarettes as an alternative to cigarettes, as well as to US Food and Drug Administration (FDA)--approved nicotine replacement therapies (NRT), we compared outcome expectancies (beliefs about the results of drug use) for the three nicotine delivery systems among vapers, i.e., e-cigarette users, who were former smokers. Vapers (N = 1,434) completed an online survey assessing 14 expectancy domains as well as perceived cost and convenience. We focused on comparisons between e-cigarettes and cigarettes to determine the attraction of e-cigarettes as a smoking alternative and between e-cigarettes and NRT to determine perceived advantages of e-cigarettes over FDA-approved pharmacotherapy. Participants believed that e-cigarettes, in comparison to conventional cigarettes, had fewer health risks; caused less craving, withdrawal, addiction, and negative physical feelings; tasted better; and were more satisfying. In contrast, conventional cigarettes were perceived as better than e-cigarettes for reducing negative affect, controlling weight, providing stimulation, and reducing stress. E-cigarettes, compared to NRT, were perceived to be less risky, cost less, cause fewer negative physical feelings, taste better, provide more satisfaction, and be better at reducing craving, negative affect, and stress. Moderator analyses indicated history with ad libitum forms of NRT was associated with less positive NRT expectancies. The degree to which expectancies for e-cigarettes differed from expectancies for either tobacco cigarettes or NRT offers insight into the motivation of e-cigarette users and provides guidance for public health and clinical interventions to encourage smoking-related behavior change. © The Author 2014.

Study the effects of the 2011 Malaysian minimum price law (MPL) on prices of licit and illicit cigarette brands. Identify barriers to the MPL achieving positive public health effects. The International Tobacco Control Project's Southeast Asia survey collected information on Malaysian smokers' cigarette purchases (n=7520) in five survey waves between 2005 and 2012. Consumption-weighted comparisons of proportions tests and adjusted Wald tests were used to evaluate changes over time in violation rates of the inflation-adjusted MPL, the proportion of illicit cigarette purchases and mean prices. After the passage of the MPL, the proportion of licit brand cigarette purchases that were below the inflation-adjusted 2011 minimum price level fell substantially (before 3.9%, after 1.8%, p=0.002), while violation of the MPL for illicit brand cigarette purchases was unchanged (before 89.8%, after 91.9%, p=0.496). At the same time, the mean real price of licit cigarettes rose (p=0.006), while the mean real price of illicit cigarettes remained unchanged (p=0.134). The proportion of illicit cigarette purchases rose as well (before 13.4%, after 16.5%, p=0.041). The MPL appears not to have meaningfully changed cigarette prices in Malaysia, as licit brand prices remained well above and illicit brand prices remained well below the minimum price level before and after MPL's implementation. The increasing proportion of illicit cigarettes on the market may have undermined any positive health effects of the Malaysian MPL. The illicit cigarette trade must be addressed before a full evaluation of the Malaysian MPL's impact on public health can take place. The authors encourage the continued use of specific excise tax increases to reliably increase the price and decrease the consumption of cigarettes in Malaysia and elsewhere.

There are limited data on the use of electronic cigarettes (e-cigarettes) among youth, particularly with regard to the use of nicotine versus nonnicotine products. This study investigates ever use of nicotine and nonnicotine e-cigarettes and examines the demographic and behavioral correlates of e-cigarette use in Ontario, Canada. Data for 2,892 high school students were derived from the 2013 Ontario Student Drug Use and Health Survey. This province-wide school-based survey is based on a 2-stage cluster design. Bivariate and multivariate analyses were used to investigate the factors associated with ever use of e-cigarettes. Ever use of e-cigarettes was derived from the question, "Have you ever smoked at least one puff from an electronic cigarette?" All analyses included appropriate adjustments for the complex study design. Fifteen percent of high school students reported using e-cigarettes in their lifetime. Most students who ever used e-cigarettes reported using e-cigarettes without nicotine (72%), but 28% had used e-cigarettes with nicotine. Male, White/Caucasian, and rural students, as well as those with a history of using tobacco cigarettes, were at greater odds of e-cigarette use. Seven percent of students who had never smoked a tobacco cigarette in their lifetime reported using an e-cigarette. Five percent of those who had ever used an e-cigarette had never smoked a tobacco cigarette. More students reported ever using e-cigarettes without nicotine than with nicotine in Ontario, Canada. This underscores the need for greater knowledge of the contents of both nicotine and nonnicotine e-cigarettes to better guide public health policies. © The Author 2014.

E-cigarettes have been suggested as a strategy for reducing harm from cigarettes. Although e-cigarettes could be a less-harmful alternative to cigarettes for those trying to quit, there may also be costs that outweigh any benefits of reduction. The purpose of the present study was to prospectively investigate perceptions of e-cigarettes, cigarette smoking intentions, and their associations with e-cigarette use over time. Community participants (N = 348, 57% male) aged 18 to 24 years were recruited for a longitudinal study of tobacco use. Inclusion criteria included nondaily cigarette smoking for ≥ 6 months with no history of daily smoking. Participants reported e-cigarette use over the past 14 days at baseline, and for the past 9 days at 3, 6, and 9 months. Assessments were completed online or via mobile phone. Across the 4 assessments, 22% to 33% of participants reported recent e-cigarette use. Intent to quit smoking cigarettes and intent to maintain smoking were unrelated to e-cigarette frequency. E-cigarette frequency was positively associated with perceiving e-cigarettes as less harmful than cigarettes and more positive e-cigarette expectancies (ps E-cigarette use was also more frequent among those who smoked cigarettes frequently and who used e-cigarettes to circumvent cigarette bans more often (ps e-cigarette use more than harm reduction. Findings instead seem consistent with the hypothesis that e-cigarettes are more often used to complement ongoing cigarette smoking. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Electronic cigarettes (ECs) are becoming popular alternatives for smokers, but there has been limited study of their abuse liability. The objective of this study was to evaluate the abuse liability of three Vuse Solo ECs, ranging from 14 to 36 mg in nicotine content, relative to high- and low-abuse liability comparator products (usual brand combustible cigarettes and nicotine gum, respectively) in a group of 45 EC-naïve smokers. Enrolled subjects' ratings of subjective effects and nicotine uptake over 6 h were used to measure abuse liability and pharmacokinetics following in-clinic use of each EC. Use of Vuse Solo resulted in subjective measures and nicotine uptake that were between those of combustible cigarettes and nicotine gum, although generally closer to nicotine gum. Compared to combustible cigarettes, use of Vuse Solo resulted in significantly lower scores in measures of product liking, positive effects, and intent to use again. These pharmacodynamic findings were consistent with the pharmacokinetic data, showing that cigarettes produced substantially faster and higher levels of nicotine uptake as compared to Vuse Solo and nicotine gum. Vuse Solo resulted in more rapid initial uptake of nicotine compared to nicotine gum, but peak concentration and long-term extent of uptake were not different or were lower with Vuse. Collectively, these findings suggest that Vuse Solo likely has an abuse liability that is somewhat greater than nicotine gum but lower than cigarettes. ClinicalTrials.gov identifier: NCT02269514.

E-cigarette use is rapidly increasing among adolescents in the United States, with some suggesting that e-cigarettes are the cause of declining youth cigarette smoking. We hypothesized that the decline in youth smoking changed after e-cigarettes arrived on the US market in 2007. Data were collected by using cross-sectional, nationally representative school-based samples of sixth- through 12th-graders from 2004-2014 National Youth Tobacco Surveys (samples ranged from 16 614 in 2013 to 25 324 in 2004). Analyses were conducted by using interrupted time series of ever (≥1 puff) and current (last 30 days) cigarette smoking. Logistic regression was used to identify psychosocial risk factors associated with cigarette smoking in the 2004-2009 samples; this model was then applied to estimate the probability of cigarette smoking among cigarette smokers and e-cigarette users in the 2011-2014 samples. Youth cigarette smoking decreased linearly between 2004 and 2014 (P = .009 for ever smoking and P = .05 for current smoking), with no significant change in this trend after 2009 (P = .57 and .23). Based on the psychosocial model of smoking, including demographic characteristics, willingness to wear clothing with a tobacco logo, living with a smoker, likelihood of smoking in the next year, likelihood of smoking cigarettes from a friend, and use of tobacco products other than cigarettes or e-cigarettes, the model categorized e-cigarette-only users (between 11.0% in 2012 and 23.1% in 2013) as current smokers. The introduction of e-cigarettes was not associated with a change in the linear decline in cigarette smoking among youth. E-cigarette-only users would be unlikely to have initiated tobacco product use with cigarettes. Copyright © 2017 by the American Academy of Pediatrics.

Tobacco use is the leading preventable cause of death worldwide. Besides cigarette smoking, waterpipe and e-cigarettes are gaining popularity among young adults. Medical students' smoking behavior is of particular interest because of their impending role in health promotion as future physicians. Aim of our study is to examine the prevalence and predictors of cigarette, waterpipe and e-cigarette use and the association of tobacco use with self-reported health status in an international sample of medical students. In a multicenter cross-sectional study data on different aspects of health behavior were collected from medical students of 65 nationalities using a self-administered questionnaire in Germany (Dresden, Munich) and Hungary (Budapest, Pécs). The survey was conducted among 1st, 3rd and 5th year students. To explore associations between smoking behavior and socio-cultural factors Pearson's chi 2 -tests and multivariate binary logistic regression analyses were performed. The largest subpopulations were formed by German (n = 1289), Hungarian (n = 1055) and Norwegian (n = 147) students. Mean age was 22.5 ± 3.3 years. Females represented 61.6% of the sample. In the whole sample prevalence of cigarette smoking was 18.0% (95% CI 16.6-19.4%), prevalence of waterpipe use was 4.8% (95% CI 4.0-5.7%), that of e-cigarette 0.9% (95% CI 0.5-1.2%). More males (22.0%) than females (15.5%) reported cigarette smoking. The lowest prevalence of cigarette smoking was found among Norwegian students (6.2%). Cigarette smokers were older, waterpipe users were younger than non-users. E-cigarette use was not associated with age of the students. Religious involvement was protective only against cigarette smoking. Financial situation showed no association with any kind of tobacco consumption. Cigarette smokers and e-cigarette users were less likely to report very good or excellent health status. Cigarette smoking is still the most popular way of consuming tobacco

This paper examines the impact on cigarette sales of the successive increases in cigarette prices in France from 2002 to 2004. Since the price differential between France and neighboring countries increased over the period in question, cross-border purchases became more financially attractive for smokers living near borders. Results from difference-in-differences estimates indicate that the decrease in cigarette sales observed in French border departments was around 20 % higher from 2004 to 2007 compared to non-border departments. The loss of fiscal revenue due to cross-border shopping since the tax increase amounts to 2 billion euros over the period 2002-2007. Our findings highlight the need for improved coordination of policies aimed at reducing tobacco consumption across European Union countries.

Many smokers who have tried electronic cigarettes ('e-cigarettes') continue to smoke, perhaps influenced by their beliefs about the outcomes of using e-cigarettes ('e-cigarette expectancies'). The primary aims of this study were to compare expectancies of dual users to former smokers, and to examine the association between expectancies and intentions to quit or reduce 'vaping' among former smokers. A large cross-sectional online survey of e-cigarette users conducted in the United States. We surveyed current e-cigarette users (n = 1815), including both current cigarette smokers ('dual users', n = 381) and former smokers (n = 1434). We further subdivided former smokers into those with (n = 686) and without (n = 748) intentions to reduce or quit e-cigarette use. The primary outcomes were self-reported past-month smoking status and, among former smokers, current intentions to reduce or quit e-cigarette use, both adjusted for potential confounders. E-cigarette expectancy items were derived primarily from a previously validated measure of smoking expectancies. Dual users reported less positive expectancies than former smokers about e-cigarettes, rating e-cigarettes as more physically irritating (β = 0.10, P addictive (β = 0.06, P = 0.016), as well as less satisfying (β = -0.11, P addiction (β = 0.10, P e-cigarette expectancies among e-cigarette users are associated with a greater likelihood of having quit smoking, but lower likelihood of intention to quit e-cigarette use. © 2015 Society for the Study of Addiction.

Electronic cigarettes (e-cigarettes) have gained popularity rapidly in the Western world but data in the East are scarce. We examined the awareness and ever use of e-cigarettes, and reasons for e-cigarette use in a probability sample of adults in Hong Kong. Cross-sectional data were collected in 2014 from Chinese adults aged 15-65 in Hong Kong (819 never smokers, 800 former smokers, 800 current smokers) via computer-assisted telephone interviews (response rate: 73.8%). Analysis was limited to a subset of 809 respondents (i.e., 357 never smokers, 269 former smokers, 183 current smokers) who were randomly selected to answer questions on e-cigarettes. Chi-square analyses compared e-cigarette awareness and ever use by gender, age, education, and cigarette smoking status. Multivariable logistic regression examined if e-cigarette awareness was associated with demographic variables and cigarette smoking status. 75.4% of adults had heard of e-cigarettes, and 2.3% reported having used e-cigarettes. Greater awareness was associated with male gender and higher education. Ever use of e-cigarettes was higher among males (3.6%, p=.03), younger adults (aged 15-29, 5.2%, p=.002), and current cigarette smokers (11.8%, preasons for using e-cigarettes were curiosity (47.4%), the stylish product design (25.8%), and quitting smoking (13.6%). Awareness of e-cigarettes was widespread in Hong Kong. Although the use of e-cigarettes was low, its relation with younger age and current smoking is of concern. Health surveillance of e-cigarette use is needed. Interventions should target young adults and cigarette smokers, and address the marketing messages, especially the effect of e-cigarettes on smoking cessation. Copyright © 2015 Elsevier Ltd.

Background: The hazards of cigarette smoking and its increasing consumption are well known despite the ongoing tussle between the tobacco industry and global governments. To curb the menace of smoking, anti-smoking laws have been enforced from time to time by various governments. In 2003, Ministry of Health (MoH) Government of Pakistan has imposed certain regulations on cigarette manufacturing industry. The aim of this study was to highlight the compliance of the industry with these regulations. Methods: A cross-sectional study of major cigarette selling shops was conducted in Abbottabad. It was aimed at determining the availability of total cigarette brands and their compliance with the regulations and also to find out attributes of cigarette customers. Results: A total of 39 varieties of 18 cigarette brands are available in Abbottabad city, out of which 71.8% are imported varieties. A total of 38.4% varieties have displayed health warnings (28.2% pictorial health warning, 10.2% have written health warning. Majority of cigarette customers are between 20-40 years of age, while 5.6% customers include youngsters between 10-20 years of age. Female customers, accounting for 8% of total cigarette customers, buy only those brands which have not displayed the health warning. Conclusions: Observed compliance with governmental regulation for displaying health warning is 39% which is far less than desired. Sale of cigarette to children is also practiced. Ministry of Health (MoH) should assure the display of these warnings on all the brands so that smokers must be fully aware about the risk involved in smoking. (author)

Certain tobacco companies use health-oriented descriptors (eg, 100% organic) on product packaging and advertising of combustible cigarettes or electronic cigarettes (e-cigarettes) that create a 'health halo' around smoking and vaping. Previous observational research suggests that such language may be associated with more favourable attitudes and reduced risk perceptions toward these brands compared with others. This study aimed to determine the effects of health-oriented descriptors on smokers' attitude toward the brand, perception of packaging information, comparative harm versus other brands and intention to purchase either combustible cigarettes or e-cigarettes. US adult smokers were randomly assigned to view either a health-oriented language package ('100% organic,' 'all natural' or 'no additives'), traditional marketing language package ('fine quality,' 'premium blend' or '100% original') or a no-language package of a combustible cigarette brand (Study 1, n=405) or an e-cigarette brand (Study 2, n=396) in an experimental design. Study 1: Participants in the health-oriented condition reported more favourable perceptions toward the package information, lower comparative harm and higher intention to purchase combustible cigarettes versus the no language control. In addition, participants in the health-oriented condition reported more positive attitude toward the brand and lower comparative harm versus the traditional marketing condition. Study 2: Compared with the traditional marketing condition, participants in the health-oriented condition reported greater intention to purchase Absolute e-cigarettes. There were no significant differences in attitude toward the brand, perception of packaging information and comparative harm versus other brands across conditions. The effect of health-oriented language was significant for combustible cigarettesand e-cigarette packages. Policies to restrict health-oriented language on cigarette and e-cigarette packaging are

The aim of the study was to characterize e-cigarette users in terms of their consumption patterns, motives, and the perceived health benefits they experience from using e-cigarettes. The study was a cross-sectional online survey in 2015. A total of 3,320 German e-cigarette users were enrolled. A total of 91.5% were former tobacco smokers, 7.5% used both e-cigarettes and tobacco products, 1.0% were never-smokers. No differences were found between ex-smokers and dual users with regard to sociodemographic and smoking history (mean age 40.8 years, 81% men, 45% with a high school degree or above). Both groups had smoked 26.4 tobacco cigarettes a day for 22 years, had unsuccessfully tried to quit smoking using various other nicotine replacement products, and had used e-cigarettes for an average of 2 years. Ex-smokers consumed lower nicotine strength and more liquid per month, experienced more positive health changes, and had made vaping their hobby. Never-smokers were about 5 years younger, used liquid without nicotine and without tobacco flavor, and had no physical dependency. E-cigarettes were primarily used as an alternative to smoking and a substitute for nicotine. More dual users than ex-smokers used e-cigarettes in places where smoking is forbidden. Positive health changes were more pronounced in ex-smokers than dual users. © 2017 S. Karger AG, Basel.

Cigarette smoking is associated with various cutaneous disorders with defective permeability. Yet, whether cigarette smoking influences epidermal permeability barrier function is largely unknown. Here, we measured skin biophysical properties, including permeability barrier homeostasis, stratum corneum (SC) integrity, SC hydration, skin surface pH, and skin melanin/erythema index, in cigarette smokers. A total of 99 male volunteers were enrolled in this study. Smokers were categorized as light-to-moderate (hydration and skin melanin/erythema index on the dorsal hand, forehead, and cheek. Basal transepidermal water loss (TEWL) and barrier recovery rates were assessed on the forearm. A Skin-pH-Meter pH900 was used to measure skin surface pH. Our results showed that heavy cigarette smokers exhibited delayed barrier recovery after acute abrogation (1.02% ± 13.06 versus 16.48% ± 6.07), and barrier recovery rates correlated negatively with the number of daily cigarettes consumption (p = 0.0087). Changes in biophysical parameters in cigarette smokers varied with body sites. In conclusion, heavy cigarette smokers display compromised permeability barrier homeostasis, which could contribute, in part, to the increased prevalence of certain cutaneous disorders characterized by defective permeability. Thus, improving epidermal permeability barrier should be considered for heavy cigarette smokers. PMID:27437403

Cigarette smoking is highly prevalent in people with substance use disorders (SUDs) and is associated with significant physical health problems. Posttraumatic stress disorder (PTSD) is also highly associated with both SUDs and cigarette smoking and may serve as a barrier to smoking cessation efforts. In addition, people with PTSD are more likely to hold positive smoking outcome expectancies (i.e., beliefs that smoking cigarettes results in positive outcomes); these beliefs may contribute to cigarette smoking in people with SUDs experiencing PTSD symptoms. The present study examined the relationship between PTSD symptoms and typical daily cigarette smoking/cigarette dependence symptoms in a sample of 227 trauma-exposed current smokers with SUDs (59.9% male, 89.4% Caucasian) seeking detoxification treatment services. Additionally, the indirect effects of multiple types of positive smoking outcome expectancies on these relationships were examined. Participants completed questionnaires assessing PTSD symptoms, positive smoking outcome expectancies, cigarette consumption, and cigarette dependence symptoms. Results indicated that PTSD symptoms were not directly related to cigarette consumption or cigarette dependence symptoms. However, negative affect reduction outcome expectancies were shown to have a significant indirect effect between PTSD symptoms and cigarette consumption, while negative affect reduction, boredom reduction, and taste-sensorimotor manipulation outcome expectancies were all found to have significant indirect effects between PTSD symptoms and cigarette dependence symptoms. The indirect effect involving negative affect reduction outcome expectancies was statistically larger than that of taste sensorimotor manipulation outcome expectancies, while negative affect reduction and boredom reduction outcome expectancies were comparable in magnitude. These results suggest that expectancies that smoking can manage negative affective experiences are related to

Full Text Available Objective. To determine the prevalence of the smoking habit among Mexican physicians as well as some of their attitudes and information on specific issues concerning smoking. Material and methods. In 1993, a survey was carried out among 3 568 physicians of the three major official health care institutions in Mexico City. A questionnaire designed for The Mexican National Survey of Addictions (ENA 1993 was used. Prevalence of cigarette smoking, age of onset, number of cigarettes per day; also information and attitudes concerning smoking were assessed. Results. The mean age was 37, 66% were males. Of the 3,488 (98% surveyed, 26.9% were smokers (62% daily, 20.6% were ex-smokers and 52.5% non-smokers. There were differences related to age and sex (p< 0.05. Of daily smokers, 36% smoked between 1 and 5 cigarettes. There was a significant trend among ex-smokers that linked the time they had ceased smoking with the fear to start smoking again. Physicians were well informed of the relationship between cigarette smoking and lung cancer. Over 80% considered tobacco an addictive drug but only 65% were in favor of banning smoking from their workplaces and over 10% were not aware that it is forbidden to smoke inside health care facilities. Conclusions. These results differ from other studies that find the prevalence of smoking among physicians lower than in the general population. Our study revealed a greater prevalence of the smoking habit among female physicians and the number of cigarettes smoked per day was greater than in the general population regardless of sex.

past 30-day e-cigarette users and 4.6% for baseline non-past 30-day e-cigarette users. Adjusting for known demographic, psychosocial, and behavioral risk factors for cigarette smoking, the pooled odds ratio for subsequent cigarette smoking initiation was 3.62 (95% CI, 2.42-5.41) for ever vs never e-cigarette users, and the pooled odds ratio for past 30-day cigarette smoking at follow-up was 4.28 (95% CI, 2.52-7.27) for past 30-day e-cigarette vs non-past 30-day e-cigarette users at baseline. A moderate level of heterogeneity was observed among studies (I2 = 60.1%). e-Cigarette use was associated with greater risk for subsequent cigarette smoking initiation and past 30-day cigarette smoking. Strong e-cigarette regulation could potentially curb use among youth and possibly limit the future population-level burden of cigarette smoking.

This study examined the effect of exposure to "cigalike" (products resembling cigarettes) e-cigarette advertisements on adolescents' perceptions of cigarettes. A nationally representative sample of 802 adolescents (13-17 years old) was randomly assigned to watch three e-cigarette or three control advertisements. Never-smokers who saw the e-cigarette advertisements (n = 352) reported significantly lower perceived risks of smoking than those in the control condition (n = 320). Ever-smokers (n = 130) did not show significant differences across the conditions. In subgroup analyses, current smokers (reported smoking in the past 30 days, n = 31) in the e-cigarette condition reported significantly lower perceived benefits of smoking than those in the control condition. E-cigarette advertisements can affect adolescents' perceptions of cigarettes. Many advertisements, especially the ones promoting "cigalikes," depict e-cigarettes as being similar to cigarettes (e.g., look, flavor) but also as a solution for cigarettes' shortcomings (e.g., bad smell). While the advertisements include messages about problems posed by cigarettes, proposing e-cigarettes as a solution may decrease the perceived risks of smoking among never-smokers. It may also not be clear to adolescents whether advertisements are for cigarettes or e-cigarettes. Regulating e-cigarette advertisements to minimize adolescents' exposure may prevent potential harmful effects on never-smokers' perception of smoking.

Full Text Available Minimization of post-cessation weight gain in quitters is important, but existing approaches (e.g., antismoking medications shows only limited success. We investigated changes in body weight in smokers who quit or reduced substantially their cigarette consumption by switching to electronic cigarettes (ECs use. Body weight and smoking/vaping history were extracted from medical records of smokers and ex-smokers to match three study groups: (1 regular EC users on at least two consecutive follow-up visits; (2 regular smokers (and not using ECs; (3 subjects who reported sustained smoking abstinence after completing a cessation program. Review of their medical records was conducted at two follow-up visits at 6- (F/U 6m and 12-months (F/U 12m. A total of 86 EC users, 93 regular smokers, and 44 quitters were studied. In the EC users study group, cigarettes/day use decreased from 21.1 at baseline to 1.8 at F/U 12m (p < 0.0001. Dual usage was reported by approximately 50% of EC users. Both within factor (time, p < 0.0001 and between factor (study groups, p < 0.0001 produced significant effect on weight (% change from baseline, with a significant 4.8% weight gain from baseline in the quitters study group at F/U 12m. For the EC users, weight gain at F/U 12m was only 1.5% of baseline. There was no evidence of post-cessation weight increase in those who reduced substantially cigarette consumption by switching to ECs (i.e., dual users and only modest post-cessation weight increase was reported in exclusive EC users at F/U 12m. By reducing weight gain and tobacco consumption, EC-based interventions may promote an overall improvement in quality of life.

The objective of this experiment was to evaluate the comparative value of cigarettes versus high dose e-cigarettes among nicotine-dependent cigarette smokers when compared with money or use of their usual cigarette brand. The experiment used a within-subject design with four sessions. After baseline assessment, participants attended two 15-min unrestricted smoking sessions: one cigarette smoking session and one e-cigarette smoking session. Participants then attended two multiple-choice procedure (MCP) sessions: a session comparing cigarettes and money and a session comparing e-cigarettes and money. Participants (n=27) had used cigarettes regularly, had never used e-cigarettes, and were not currently attempting to quit smoking. The sample consisted primarily of males (72%), with a mean age of 34 years. When given the opportunity to choose between smoking a cigarette or an e-cigarette, participants chose the cigarette 73.9% of the time. Findings from the MCP demonstrated that after the first e-cigarette exposure sessions, the crossover value for cigarettes ($3.45) was significantly higher compared with the crossover value for e-cigarettes ($2.73). The higher participant preference, self-reported smoking effects, and higher MCP crossover points indicate that cigarettes have a higher comparative value than high dose e-cigarettes among e-cigarette naive smokers.

To describe knowledge of electronic cigarettes (e-cigarettes) and their perceived harmfulness in the population of Barcelona in 2013-2014. We used participants from a longitudinal study of a representative sample of the adult population in the city of Barcelona (n=736). The field work was conducted between May 2013 and February 2014. Awareness of e-cigarette was 79.2%. The average level of knowledge was 4.4 points out of 10; there were statistically significant differences according to age, educational level, tobacco consumption, and nicotine dependence. Most participants had learned about e-cigarettes through traditional media (57.8%). Nearly half (47.2%) of the participants believed that e-cigarettes are less harmful than conventional cigarettes. Advertising of e-cigarettes in the media should be regulated because there is still scarce scientific evidence about the usefulness and harmful effects of these devices. Copyright © 2014 SESPAS.

To assess the profile, utilization patterns, satisfaction and perceived effects among users of electronic cigarettes ('e-cigarettes'). Internet survey in English and French in 2010. Online questionnaire. Visitors of websites and online discussion forums dedicated to e-cigarettes and to smoking cessation. There were 3587 participants (70% former tobacco smokers, 61% men, mean age 41 years). The median duration of electronic cigarette use was 3 months, users drew 120 puffs/day and used five refills/day. Almost all (97%) used e-cigarettes containing nicotine. Daily users spent $33 per month on these products. Most (96%) said the e-cigarette helped them to quit smoking or reduce their smoking (92%). Reasons for using the e-cigarette included the perception that it was less toxic than tobacco (84%), to deal with craving for tobacco (79%) and withdrawal symptoms (67%), to quit smoking or avoid relapsing (77%), because it was cheaper than smoking (57%) and to deal with situations where smoking was prohibited (39%). Most ex-smokers (79%) feared they might relapse to smoking if they stopped using the e-cigarette. Users of nicotine-containing e-cigarettes reported better relief of withdrawal and a greater effect on smoking cessation than those using non-nicotine e-cigarettes. E-cigarettes were used much as people would use nicotine replacement medications: by former smokers to avoid relapse or as an aid to cut down or quit smoking. Further research should evaluate the safety and efficacy of e-cigarettes for administration of nicotine and other substances, and for quitting and relapse prevention. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

To test whether exposure and receptivity to e-cigarette marketing are associated with recent e-cigarette use among young adults through increased beliefs that e-cigarettes are less harmful than cigarettes. Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette smokers [mean age = 23.5 (SD = 5.5); 65% female]. Higher receptivity to e-cigarette marketing was associated with perceptions that e-cigarettes are less harmful than cigarettes, which in turn, were associated with higher recent e-cigarette use. The findings provide preliminary support to the proposition that marketing of e-cigarettes as safer alternatives to cigarettes or cessation aids is associated with increased e-cigarette use among young adults. The findings have implications for development of e-cigarette regulations.

Higher cigarette taxes--healthier people, wealthier state: the Hungarian experience.

Szilágyi, Tibor

2007-09-01

To prove that higher cigarette taxes eventually decrease smoking and do also increase state incomes from tobacco taxes by using Hungarian figures. Collection and analysis of available data on tobacco use, levels of excise and value added taxes on tobacco products and state incomes originating from the tobacco sector. In Hungary, regular tobacco tax increases resulted in decreased cigarette consumption and its lower prevalence figures in some population groups. State incomes have increased in spite of regular cigarette tax raises. Therefore, there is on conflict of interest between the health and finance portfolios in supporting further tobacco tax increases. Hungary should use regular, above the inflation tobacco tax raises as means for improving population health. Tobacco control advocates should prevent tobacco companies' attempts aimed at deterring decision makers from supporting such tax policies.

The knowledge about the effect of cigarette smoking on the male reproductive function is still limited. The objective of this study was to evaluate the association between active exposure to tobacco smoke and the male reproductive hormone profile in a group of 136 Mexican flower growers. Serum levels of FSH, LH, prolactin, total testosterone, Inhibin B and estradiol were measured using enzyme-linked immunoabsorbent assay. Weight and height were also measured and a structured questionnaire was applied to get information on sociodemographic characteristics, clinical and work history and alcohol and tobacco consumption (current smoking habit and number of cigarettes smoked per day). Based on this information tobacco consumption was divided into four categories: never-smokers, ex-smokers, current smokers under five cigarettes/day and current smokers over or equal to five cigarettes/day. Using the group of never-smokers as reference and after adjusting for potential confounders, current smokers of five or more cigarettes/day showed significantly higher levels of LH (β=0.33, p=0.01), prolactin (β=0.18, p=0.03) and testosterone (β=0.21, p=0.02). Current smokers of less than five cigarettes/day also showed higher levels of prolactin (β=0.12, p=0.03) and testosterone (β=0.18, pconsumption may act as an endocrine disruptor on the male hormone profile.

Introduction: There is limited evidence on electronic cigarette (e-cigarette) use among U.S. adolescents. Methods: Cross-sectional, anonymous surveys conducted in 4 high schools (HS; n = 3,614) and 2 middle schools (MS; n = 1,166) in Connecticut in November 2013 examined e-cigarette awareness, use patterns, susceptibility to future use, preferences, product components used (battery type, nicotine content, flavors), and sources of marketing and access. Results: High rates of awareness (MS: 84.3%; HS: 92.0%) and of lifetime (3.5% MS, 25.2 % HS) and current (1.5% MS, 12% HS) use of e-cigarettes was observed. Among those who had not tried e-cigarettes, 26.4% of MS and 31.7% of HS students reported being susceptible to future use. Males (OR = 1.70, p e-cigarette users and to report greater future susceptibility (males: OR = 1.30; Caucasians: OR = 1.14; ever cigarette smokers; OR = 3.85; current cigarette smokers; OR = 9.81; ps e-cigarette users, 51.2% reported that e-cigarette was the first tobacco product they had tried. E-cigarettes that were rechargeable and had sweet flavors were most popular. Smokers preferred e-cigarettes to cigarettes. Current cigarette smokers were more likely to initiate with nicotine-containing e-cigarettes, and ever and never cigarette smokers to initiate with e-cigarettes without nicotine. Primary sources for e-cigarette advertisements were televisions and gas stations and, for acquiring e-cigarettes, were peers. Conclusions: Longitudinal monitoring of e-cigarette use among adolescents and establishment of policies to limit access are imperatively needed. PMID:25385873

O'Connell, Grant; Graff, Donald W; D'Ruiz, Carl D

2016-07-01

Changes in fifteen urine, blood and exhaled breath BoEs of HPHCs representing classes of compounds reported by FDA to be significant contributors to smoking-associated disease risks were measured in 105 clinical-confined subjects following randomization and a five-day forced-switch from usual brand conventional combustible cigarettes to: (i) exclusive commercial e-cigarette use; (ii) dual-use of commercial e-cigarettes and the subject's usual cigarette brand; or (iii) discontinued use of all tobacco or nicotine products. Levels of urinary biomarkers in subjects that completely substituted their usual cigarette with e-cigarettes were significantly lower (29-95%) after 5 days. Percent reductions in eight of nine urinary BoEs were indistinguishable to smokers who had quit smoking, except for nicotine equivalents, which declined by 25-40%. Dual users who halved self-reported daily cigarette consumption with e-cigarettes exhibited reductions (7-38%) in eight of nine urinary biomarkers, but had increase (1-20%) in nicotine equivalents. Reductions were broadly proportional to the reduced numbers of cigarettes smoked. Dual user urinary nicotine equivalents were slightly higher, but not statistically significant. After 5 days, blood nicotine biomarker levels were lower in the cessation (75-96%) and exclusive use groups (11-83%); with dual users experiencing no significant reductions. All subjects experienced significant decreases in exhaled CO. Decreases in the cessation and exclusive groups ranged from 88-89% and 27-32% in dual users. Exhaled NO increased in the cessation and exclusive groups (46-63% respectively), whereas the dual users experienced minimal changes. Overall, smokers who completely or partially substituted conventional cigarettes with e-cigarettes over five days, experienced reductions in HPHCs.

Turning off the tap: the real solution to cigarette smuggling.

Science.gov (United States)

Joossens, L; Raw, M

2003-03-01

The tobacco industry has argued that tobacco smuggling is caused by market forces, i.e., by the price differences between countries, which create an incentive to smuggle cigarettes from 'cheaper' to 'more expensive' countries, and so urged governments to solve the problem by reducing taxes to remove this differential, which will also, they say, restore revenue. Although such market forces have some effect, smuggling is in fact more prevalent in 'cheaper' countries, and reducing tax is not the solution. Where taxes have been reduced tobacco consumption has risen and revenue has fallen, with disastrous consequences for public health. The key to understanding cigarette smuggling is understanding the role of the tobacco industry. At the heart of cigarette smuggling is large scale fraud: container loads of cigarettes are exported, legally and duty unpaid, to countries where they have no market, and where they disappear into the contraband market. They are often smuggled back into the country of origin, where they are sold at a third to half price. It is therefore profitable because duty has been illegally evaded. The key to controlling cigarette smuggling is not lowering taxes, it is controlling the tobacco manufacturing industry and its exporting practices.

Berry, Christopher; Burton, Scot; Howlett, Elizabeth

2017-10-01

This research examines cigarette smokers' and e-cigarette users' product-related health-risk beliefs across tobacco products and considers the effects of addiction warnings on consumers' responses to persuasion attempts. Study 1 used a cross-sectional survey with a sample of 195 adult cigarette smokers, e-cigarette users, and dual users to examine health-risk beliefs associated with combustible cigarettes and e-cigarettes (cancer, lung disease, stroke, heart disease, harm to an unborn baby, and addiction). Using a sample of 265 adult cigarette smokers, e-cigarette users, and dual users, Study 2 used a between-subjects experiment to examine the effects of an addiction warning presented in an advertisement on health-risk beliefs and willingness to try the promoted product. Study 1 results reveal that health-risk beliefs for cigarettes are extremely high, whereas health-risk beliefs for e-cigarettes are lower and vary across specific health-risk beliefs; specifically, beliefs related to addiction and harm to an unborn baby are greater than other risk beliefs. Extending these findings, Study 2 results demonstrate that health-risk beliefs associated with cigarette smoking are not affected by an addiction warning in a cigarette advertisement. However, an addiction warning in an e-cigarette advertisement does modify e-cigarette-related risk beliefs, which, in turn, reduces consumers' willingness to try the promoted e-cigarette. Findings indicate that the addition of an addiction warning may be effective in changing consumers' risk beliefs associated with e-cigarettes and consumers' responses to e-cigarette persuasion attempts. By examining cigarette smokers' and e-cigarette users' product-related health-risk beliefs and considering the effects of an addiction warning on consumers' responses to persuasion attempts, this research contributes to the understanding of how warnings in tobacco promotion affect cigarette smokers', e-cigarette users', and dual users' health

We examined the relationships between e-cigarette use and subsequent cigarette smoking behaviors at 6- and 12-month follow-ups among young adults. Participants were 18-29 year-old current and former cigarette smokers (N = 627) at 24 Texas colleges, participating in a 3-wave study. Multi-level, multivariable logistic regression models, accounting for school clustering, examined the impact of self-reported use of e-cigarettes on cigarette smoking status at 6- and 12-month follow-ups. Two mutually-exclusive groups of e-cigarette users were examined: those that used for cigarette smoking cessation and those that used for reasons other than cessation. Baseline covariates included socio-demographics, past quit attempts, nicotine dependence, cigarettes per day, and other tobacco use. Use of e-cigarettes for cigarette smoking cessation was associated with increased odds of cigarette smoking cessation at 6- and 12-month follow-ups, while using e-cigarettes for other reasons was not, when adjusting for covariates. Use of e-cigarettes for cigarette smoking cessation may reduce cigarette smoking rates in young adult college students. Additional research is needed examining e-cigarettes as a complement to evidence-based cessation resources that are associated with cigarette smoking cessation among young adults.

We examined effects of long-term medical marijuana legalization on cigarette co-use in a sample of adults. We conducted secondary analysis using data from the 2014 US Tobacco Attitudes and Beliefs Survey, which consisted of cigarette smokers, aged ≥ 45 years (N = 506). Participants were categorized by their state residence, where medical marijuana was (1) illegal, (2) legalized legalized ≥ 10 years. The Web-based survey assessed participants' marijuana use, beliefs and attitudes on marijuana, and nicotine dependence using Fagerstrom Tolerance for Nicotine Dependence (FTND) and Hooked on Nicotine Checklist (HONC) scores. In cigarette smokers aged ≥ 45 years, long-term legalization of medical marijuana was associated with stable positive increases in marijuana use prevalence (ever in a lifetime) (p = .005) and frequency (number of days in past 30 days) (unadjusted p = .005; adjusted p = .08). Those who reported marijuana co-use had greater FTND and HONC scores after adjusting for covariates (p = .05). These preliminary findings warrant further examination of the potential impact of long-term legalization of medical marijuana on greater cigarette and marijuana co-use in adults and higher nicotine dependence among co-users at the population level.

E-Cigarettes and the Use of Conventional Cigarettes.

In 2015, 12.1% of 12- to 17-year-olds in Germany had reportedly already tried e-cigarette smoking at least once. We carried out a study of the "gateway" hypothesis, according to which the use of e-cigarettes can motivate adolescents to start smoking conventional cigarettes. During the 2015/2016 school year, 2186 tenth-graders in the German states of Lower Saxony and Schleswig-Holstein who had never smoked conventional cigarettes before took part in a survey over a 6-month period (mean age 15.5 years, standard deviation 0.65; 53.6% female). 14.3% of the survey population (313 adolescents) said at the start of the survey period that they had already tried e-cigarettes at least once. By the end of the survey period, 12.3% (268) of those who had never smoked before had begun to experiment with conventional cigarettes. The risk of beginning such experimentation was 2.2 times higher among e-cigarette users. This association remained (relative risk = 2.18 [1.65; 2.83]) after statistical control for age, sex, state, immigrant background, type of school, socioeconomic status, various personality traits (sensation-seeking, impulsivity, anxiety, hopelessness, extraversion, agreeableness, conscientiousness, neuroticism, openness), and the use of alcohol, cannabis, and other illicit drugs. Further analysis revealed that the association between the use of e-cigarettes and the onset of conventional cigarette smoking was stronger among adolescents with low sensation-seeking scores and without any experience of alcohol intoxication. Among adolescents who have never smoked, experimentation with conventional cigarettes is more common in those who have used e-cigarettes. This effect seems to be stronger among adolescents who, in general, have a lower risk of starting to smoke. The 6-month observation period of this study is too short to allow any inference regarding a connection between e-cigarette use and the development of tobacco dependence.

No sisyphean task: how the FDA can regulate electronic cigarettes.

Science.gov (United States)

Paradise, Jordan

2013-01-01

The adverse effects of smoking have fostered a natural market for smoking cessation and smoking reduction products. Smokers attempting to quit or reduce consumption have tried everything: "low" or "light" cigarettes; nicotine-infused chewing gum, lozenges, and lollipops; dermal patches; and even hypnosis. The latest craze in the quest to find a safer source of nicotine is the electronic cigarette. Electronic cigarettes (e-cigarettes) have swept the market, reaching a rapidly expanding international consumer base. Boasting nicotine delivery and the tactile feel of a traditional cigarette without the dozens of other chemical constituents that contribute to carcinogenicity, e-cigarettes are often portrayed as less risky, as a smoking reduction or even a complete smoking cessation product, and perhaps most troubling for its appeal to youth, as a flavorful, trendy, and convenient accessory. The sensationalism associated with e-cigarettes has spurred outcry from health and medical professional groups, as well as the Food and Drug Administration (FDA), because of the unknown effects on public health. Inhabiting a realm of products deemed "tobacco products" under recent 2009 legislation, e-cigarettes pose new challenges to FDA regulation because of their novel method of nicotine delivery, various mechanical and electrical parts, and nearly nonexistent safety data. Consumer use, marketing and promotional claims, and technological characteristics of e-cigarettes have also raised decades old questions of when the FDA can assert authority over products as drugs or medical devices. Recent case law restricting FDA enforcement efforts against e-cigarettes further confounds the distinction among drugs and medical devices, emerging e-cigarette products, and traditional tobacco products such as cigarettes, cigars, and smokeless tobacco. This Article investigates the e-cigarette phenomenon in the wake of the recently enacted Family Smoking Prevention and Tobacco Control Act of 2009

E-Cigarettes and “Dripping” Among High-School Youth

BACKGROUND: Electronic cigarettes (e-cigarettes) electrically heat and vaporize e-liquids to produce inhalable vapors. These devices are being used to inhale vapors produced by dripping e-liquids directly onto heated atomizers. The current study conducts the first evaluation of the prevalence rates and reasons for using e-cigarettes for dripping among high school students. METHODS: In the spring of 2015, students from 8 Connecticut high schools (n = 7045) completed anonymous surveys that examined tobacco use behaviors and perceptions. We assessed prevalence rates of ever using e-cigarettes for dripping, reasons for dripping, and predictors of dripping behaviors among those who reported ever use of e-cigarettes. RESULTS: Among 1080 ever e-cigarette users, 26.1% of students reported ever using e-cigarettes for dripping. Reasons for dripping included produced thicker clouds of vapor (63.5%), made flavors taste better (38.7%), produced a stronger throat hit (27.7%), curiosity (21.6%), and other (7.5%). Logistic regression analyses indicated that male adolescents (odds ratio [OR] = 1.64), whites (OR = 1.46), and those who had tried multiple tobacco products (OR = 1.34) and had greater past-month e-cigarette use frequency (OR = 1.07) were more likely to use dripping (Ps < .05). CONCLUSIONS: These findings indicate that a substantial portion (∼1 in 4) of high school adolescents who had ever used e-cigarettes also report using the device for dripping. Future efforts must examine the progression and toxicity of the use of e-cigarettes for dripping among youth and educate them about the potential dangers of these behaviors. PMID:28167512

Perceptions about e-cigarette safety may lead to e-smoking during pregnancy.

Electronic cigarettes (e-cigarettes) are nicotine-delivery devices that are increasingly used, especially by young people. Because e-cigarettes lack many of the substances found in regular tobacco, they are often perceived as a safer smoking alternative, especially in high-risk situations such as pregnancy. However, studies suggest that it is exposure to nicotine that is most detrimental to prenatal development. The authors studied perceptions of tobacco and e-cigarette health risks using a multiple-choice survey. To study the perceived safety of e-cigarettes versus tobacco cigarettes, 184 modified Global Health Youth Surveys (WHO, http://www.who.int/tobacco/surveillance/gyts/en/ ) were completed electronically or on paper. Age range, smoking status, and perceptions about tobacco cigarettes and e-cigarettes were studied. The results verified that younger people use e-cigarettes more than older people. Tobacco cigarettes were perceived as more harmful than e-cigarettes to health in general, including lung cancer and pregnancy. Although more research is necessary, the authors postulate that the perception that e-cigarettes are safer during pregnancy may induce pregnant women to use these devices more freely. Given that nicotine is known to cause fetal harm, pregnant mothers who smoke e-cigarettes could cause even greater harm to the fetus because e-cigarettes are perceived as being safer than tobacco cigarettes. Until more data about the effects of nicotine during pregnancy are available, the authors advocate for labeling of e-cigarettes as potentially harmful, at least during pregnancy.

Electronic cigarettes (e-cigarettes) are growing in popularity, but little is known about the extent to which these products are advertised to consumers. To estimate expenditures for e-cigarette advertising in magazines, TV, the Internet, newspapers, and radio in the U.S. from 2011 to 2012. E-cigarette advertising data were obtained from leading media intelligence companies, Kantar Media and Nielsen. Estimated e-cigarette advertising expenditures were summarized across media channels for 2011 and 2012. Additional information on brands advertised and market-level buys (i.e., local versus national) also was examined. Overall, e-cigarette advertising expenditures across media channels tripled from $6.4 million in 2011 to $18.3 million in 2012. Expenditures were highest in magazines and TV and lowest in newspapers and on the Internet. More than 80 unique brands were advertised, but blu eCigs dominated ad spending, comprising 76.7% of all e-cigarette advertising expenditures in 2012. National markets were increasingly targeted from 54.9% of ad buys in 2011 to 87.0% of ad buys in 2012. E-cigarette advertising expenditures are increasing, with a greater focus on national markets and TV ads, which will likely increase consumer awareness and use of e-cigarettes in the future. Federal-level efforts are needed to mandate that e-cigarette companies report their advertising expenditures. Future studies should examine how e-cigarette advertising expenditures and message content influence consumer awareness of, interest in, and use of e-cigarettes. © 2013 American Journal of Preventive Medicine Published by American Journal of Preventive Medicine All rights reserved.

Objectives We examined psychographic characteristics associated with tobacco use among Project DECOY participants. Methods Project DECOY is a 2-year longitudinal mixed-methods study examining risk for tobacco use among 3418 young adults across 7 Georgia colleges/universities. Baseline measures included sociodemographics, tobacco use, and psychographics using the Values, Attitudes, and Lifestyle Scale. Bivariate and multivariable analyses were conducted to identify correlates of tobacco use. Results Past 30-day use prevalence was: 13.3% cigarettes; 11.3% little cigars/cigarillos (LCCs); 3.6% smokeless tobacco; 10.9% e-cigarettes; and 12.2% hookah. Controlling for sociodemographics, correlates of cigarette use included greater novelty seeking (p fashion orientation (p = .007). Correlates of smokeless tobacco use included greater novelty seeking (p = .006) and less intellectual curiosity (p fashion orientation (p = .044), and self-focused thinking (p = .002), and less social conservatism (p products.

PURPOSE Assess the prevalence and correlates of e-cigarette perceptions and trial among adolescents in Mexico, where e-cigarettes are banned. METHODS Cross-sectional data were collected in 2015 from a representative sample of middle school students (n=10,146). Prevalence of e-cigarette awareness, relative harm, and trial were estimated, adjusting for sampling weights and school-level clustering. Multilevel logistic regression models adjusted for school-level clustering to assess correlates of e-cigarette awareness and trial. Finally, students who had tried only e-cigarettes were compared with students who had tried: 1) conventional cigarettes only; 2) both e-cigarettes and conventional cigarettes (dual triers); 3) neither cigarette type (never triers). RESULTS 51% of students had heard about e-cigarettes, 19% believed e-cigarettes were less harmful than conventional cigarettes, and 10% had tried them. Independent correlates of e-cigarette awareness and trial included established risk factors for smoking, as well as technophilia (i.e., use of more media technologies) and greater Internet tobacco advertising exposure. Exclusive e-cigarette triers (4%) had significantly higher technophilia, bedroom Internet access, and Internet tobacco advertising exposure compared to conventional cigarette triers (19%) and never triers (71%), but not compared to dual triers (6%), even though dual triers had significantly stronger conventional cigarette risk factors. CONCLUSIONS This study suggests that adolescent e-cigarette awareness and use is high in Mexico, in spite of its e-cigarette ban. A significant number of medium-risk youth have tried e-cigarettes only, suggesting that e-cigarettes could lead to more intensive substance use. Strategies to reduce e-cigarette use should consider reducing exposures to Internet marketing. PMID:26903433

Despite the rapid increase in e-cigarette use among youth, little is known about the social and behavioral factors that have contributed to this rise. We investigated whether young e-cigarette users are susceptible to e-cigarette advertisements. Estimates of e-cigarette use and exposure to e-cigarette advertisements from the 2014 National Young Tobacco Survey were investigated. Factors associated with the prevalence and levels of e-cigarette use were analyzed using multinomial logistic regression. Of all respondents (n = 21,491), 19.8% had tried e-cigarettes and 9.4% were current e-cigarette users. Exposure to e-cigarette ads was prevalent among youth, with 38.6%/29.6%/53.2%/35.4% having medium to high exposure to e-cigarette ads from the Internet/newspapers/stores/TV, respectively. Current use of e-cigarettes among youth was associated with frequent exposure (high vs. low) to e-cigarette advertising from the Internet (odd ratio [OR] = 3.1, p < .0001), newspapers/magazines (OR = 2.5, p < .0001), stores (OR = 2.8, p < .0001), and TV/movies (OR = 2.1, p < .0001). In the multivariate analysis that joint analyzed four advertisement channels and covariates, greater exposure to e-cigarette ads on the Internet (adjusted OR = 1.9, p < .0001) and in retail stores (adjusted OR = 1.9, p < .0001) remained to be significantly associated with increased odds of using e-cigarettes. Vaping by other household members significantly increased the risk of adolescent e-cigarette use (OR = 8.7, p < .0001). Exposure to e-cigarette ads significantly increased susceptibility to e-cigarette use among adolescents. E-cigarette advertising regulations and educational campaigns are critically needed.

We previously reported that following a short-term product use period, use of non-menthol Vuse Solo electronic cigarettes (ECs) resulted in product effect-related subjective responses and nicotine uptake between those of combustible cigarettes (high-abuse liability comparator) and nicotine gum (low-abuse liability comparator); the results were generally closer to those of nicotine gum. Using a similar design to the previous study, we evaluated the abuse liability of three menthol-flavored Vuse Solo ECs with the same nicotine contents (14, 29, and 36 mg) in a group of EC-naïve, menthol cigarette smokers, relative to comparator products. Six-hour nicotine uptake and ratings of subjective effects were used to determine abuse liability and pharmacokinetics. Use of menthol Vuse Solo resulted in significantly lower responses to subjective measurements (product liking, intent to use product again, and liking of positive product effects), higher urge to smoke responses, and a lower peak (C max ) and overall extent (AUC 0-360 ) of nicotine uptake compared to smoking the usual brand menthol cigarette. When compared with use of nicotine gum, subjective responses to use of menthol Vuse ECs were in the same direction as those resulting from smoking cigarettes but were more similar to nicotine gum use in magnitude than they were to cigarettes. These findings are concordant with our previous results and provide evidence that menthol Vuse Solo ECs have abuse liability that is lower than menthol cigarettes and potentially greater than that of nicotine gum.

To estimate the price elasticity of cigarette demand among youth in low- and middle-income countries (LMIC). The Global Youth Tobacco Survey was used to obtain data on the smoking behaviour of 315,353 adolescents from 17 LMIC. Two-part model of cigarette demand with country fixed effects. The first part estimates the impact of prices on smoking participation while the second part estimates the impact of prices on the number of cigarettes smoked among current smokers. Besides controlling for individual characteristics such as Age, Gender, Parental Smoking and availability of Pocket Money, the authors control for confounding environmental factors such as anti-smoking sentiment, the prevalence of cigarette advertising and anti-tobacco media messAges, and ease of purchasing cigarettes. All countries in this study are represented with at least two observations over time, which allows us to control for unobserved country characteristics and/or policies that may influence smoking patterns within countries. Cigarette price is an important determinant of smoking. The estimated price elasticity of smoking participation is -0.74, and the estimated price elasticity of conditional cigarette demand is approximately -1.37. The total price elasticity of cigarette demand is -2.11, implying that an increase in price of 10% would reduce youth cigarette consumption by 21.1% at the mean.

Full Text Available Since the introduction of e-cigarettes into the U.S. market, the number and variety of vaping products have proliferated. E-hookahs are long, pen-like vaping devices that debuted in U.S. markets in 2014. By applying the Host, Agent, Vector, Environment (HAVE model, the objective of this exploratory study was to assess differences between e-cigarettes and e-hookahs to help inform tobacco regulatory science and practice. In June–August 2014, a total of 54 unique manufactured e-cigarette and e-hookah products were identified at point of sales (POS around three college campuses in Southeast U.S. Documented characteristics included brand name, disposable, rechargeable, nicotine containing, packaging, and flavor type. Descriptive analyses were conducted October to November 2014 to assess frequency and percent of product type across POS and specific characteristics. Among 54 products, 70.4% was e-cigarettes and 29.6% was e-hookahs. Across POS, drug stores and grocery stores carried e-cigarettes exclusively, while gas stations carried the greatest proportion of e-hookahs. Compared to e-hookahs, a greater proportion of e-cigarettes were non-disposable and contained nicotine; a greater proportion of e-hookahs came in fruit and other types of flavors compared to e-cigarettes. The present study suggests that e-cigarettes and e-hookahs differ by specific product characteristics and by places where they are sold. Despite these differences, the products are used for similar purposes warranting careful monitoring of industry manufacturing and marketing, because the safety of both products is still undetermined. Additional research is needed to understand the uptake and continued use of these products.

Meanings of Consumption and Abandonment: Understanding Smoking Cessation Symbolism

Directory of Open Access Journals (Sweden)

Maribel Carvalho Suarez

2014-04-01

Full Text Available In consumption studies, very little attention has been focused on investigating abandonment and, more specifically, its symbolic dimension. The present study aims to investigate how meanings are created and negotiated through the abandonment of cigarettes. This study used a qualitative methodology to collect and analyze the data generated by one-on-one semi-structured in-depth interviews with 15 Brazilian ex-smokers. Results suggest that abandonment of cigarettes can be offered as a connection, gift, or sacrifice that makes relations special and even magical. As regards abandonment, the present study evidences the interactions and movements of positive and negative meanings related to the consumption and non-consumption of a category. The study proposes a framework that highlights the cooling, decontamination, reinforcement and defensive symbolical movements, thus constructing a tool for analyzing abandonment, offering possible paths of intervention for organizations that are interested in this issue.

Abstract Changes in fifteen urine, blood and exhaled breath BoEs of HPHCs representing classes of compounds reported by FDA to be significant contributors to smoking-associated disease risks were measured in 105 clinical-confined subjects following randomization and a five-day forced-switch from usual brand conventional combustible cigarettes to: (i) exclusive commercial e-cigarette use; (ii) dual-use of commercial e-cigarettes and the subject’s usual cigarette brand; or (iii) discontinued use of all tobacco or nicotine products. Levels of urinary biomarkers in subjects that completely substituted their usual cigarette with e-cigarettes were significantly lower (29–95%) after 5 days. Percent reductions in eight of nine urinary BoEs were indistinguishable to smokers who had quit smoking, except for nicotine equivalents, which declined by 25–40%. Dual users who halved self-reported daily cigarette consumption with e-cigarettes exhibited reductions (7–38%) in eight of nine urinary biomarkers, but had increase (1–20%) in nicotine equivalents. Reductions were broadly proportional to the reduced numbers of cigarettes smoked. Dual user urinary nicotine equivalents were slightly higher, but not statistically significant. After 5 days, blood nicotine biomarker levels were lower in the cessation (75–96%) and exclusive use groups (11–83%); with dual users experiencing no significant reductions. All subjects experienced significant decreases in exhaled CO. Decreases in the cessation and exclusive groups ranged from 88–89% and 27–32% in dual users. Exhaled NO increased in the cessation and exclusive groups (46–63% respectively), whereas the dual users experienced minimal changes. Overall, smokers who completely or partially substituted conventional cigarettes with e-cigarettes over five days, experienced reductions in HPHCs. PMID:27401591

Electronic cigarettes represent an increasingly significant proportion of today's consumable tobacco products. E-cigarettes contain several chemicals which may promote oral diseases. The aim of this study was to investigate the effect of e-cigarette vapor on human gingival epithelial cells. Results show that e-cigarette vapor altered the morphology of cells from small cuboidal form to large undefined shapes. Both single and multiple exposures to e-cigarette vapor led to a bulky morphology with large faint nuclei and an enlarged cytoplasm. E-cigarette vapor also increased L-lactate dehydrogenase (LDH) activity in the targeted cells. This activity was greater with repeated exposures. Furthermore, e-cigarette vapor increased apoptotic/necrotic epithelial cell percentages compared to that observed in the control. Epithelial cell apoptosis was confirmed by TUNEL assay showing that exposure to e-cigarette vapor increased apoptotic cell numbers, particularly after two and three exposures. This negative effect involved the caspase-3 pathway, the activity of which was greater with repeated exposure and which decreased following the use of caspase-3 inhibitor. The adverse effects of e-cigarette vapor on gingival epithelial cells may lead to dysregulated gingival cell function and result in oral disease. J. Cell.

We examined the impact of e-cigarette advertising on e-cigarette use behaviors among youth over time. At baseline, 3907 students participated in a youth tobacco surveillance study from 2014-2015 and 2488 students completed a 6-month follow-up. Weighted logistic regression models investigated the recall of e-cigarette advertisements (TV/radio/billboards/retail/Internet) as a risk factor for e-cigarette perceived harm, use, and susceptibility. The odds of ever e-cigarette use was 3 times higher (AOR=2.99; 95% CI, 1.50-5.97) at 6-month follow-up among e-cigarette never-users who recalled e-cigarette advertisements in retail stores at baseline, compared to those who did not. Likewise, the odds of current e-cigarette use and susceptibility to e-cigarette use at 6-month follow-up were 2.03 (95% CI, 1.11-3.72) and 1.77 (95% CI, 1.20-2.61), respectively. Additionally, recall of e-cigarette advertisements on the Internet at baseline was significantly related to current use (AOR=2.17; 95% CI, 1.05-4.48) and susceptibility to use e-cigarettes (AOR=1.72;95% CI, 1.15-2.58) at 6-month follow-up. Recall of e-cigarette advertisements at point-of-sale and on the Internet was significantly associated with adolescent e-cigarette susceptibility and use, which supports the need to minimize adolescent exposure to these advertisements.

Prices and E-Cigarette Demand: Evidence From the European Union.

Many European Union (EU) Member States have expressed the need for EU legislation to clarify the issue of e-cigarette taxation, but the economic evidence to inform creation of such policies has been lacking. To date, only one study-on the United States only-has examined responsiveness of e-cigarette demand to price changes. We used 2011-2014 pooled time-series data on e-cigarette sales, as well as e-cigarette and cigarette prices for six EU markets (Estonia, Ireland, Latvia, Lithuania, Sweden, and the United Kingdom). We utilized static and dynamic fixed-effects models to estimate the own and cross-price elasticity of demand for e-cigarettes. In a separate model for Sweden, we examined the effects of snus prices on e-cigarette sales. Based on static models, every 10% increase in e-cigarette prices is associated with a drop in e-cigarettes sales of approximately 8.2%, while based on dynamic models, the drop is 2.7% in the short run and 11.5% in the long run. Combustible cigarette prices are positively associated with sales of e-cigarettes. Snus prices are positively associated with sales of e-cigarettes in Sweden. Our results indicate that the sales of e-cigarettes are responsive to price changes, which suggests that excise taxes can help governments to mitigate an increase in e-cigarette use. E-cigarettes and regular cigarettes are substitutes, with higher cigarette prices being associated with increased e-cigarette sales. Making combustible cigarettes more expensive compared to e-cigarettes could be effective in moving current combustible smokers to e-cigarettes, which might have positive health effects. This study is an exploratory analysis of the issues around e-cigarette taxation in Europe. Our results suggest that taxation is a measure that could potentially address the concerns of both opponents and proponents of e-cigarettes: taxes on e-cigarettes could be used to raise prices so as to deter e-cigarette initiation by never users, while concomitant greater

Behavioral economic substitutability of e-cigarettes, tobacco cigarettes, and nicotine gum.

The public health impact of e-cigarettes may depend on their substitutability for tobacco cigarettes. Dual users of e-cigarettes and tobacco cigarettes completed purchasing tasks in which they specified daily use levels under hypothetical conditions that varied the availability and price of e-cigarettes, tobacco cigarettes, and nicotine gum (for those with nicotine gum experience). When either e-cigarettes or tobacco cigarettes were the only available commodity, as price per puff increased, purchasing decreased, revealing similar reinforcement profiles. When available concurrently, as the price of tobacco puffs increased, purchasing of tobacco puffs decreased while purchasing of fixed-price e-cigarette puffs increased. Among those with nicotine gum experience, when the price of tobacco puffs was closest to the actual market value of tobacco puffs, e-cigarette availability decreased median tobacco puff purchases by 44% compared to when tobacco was available alone. In contrast, nicotine gum availability caused no decrease in tobacco puff purchases. E-cigarettes may serve as a behavioral economic substitute for tobacco cigarettes, and may be a superior substitute compared to nicotine gum in their ability to decrease tobacco use. Although important questions remain regarding the health impacts of e-cigarettes, these data are consistent with the possibility that e-cigarettes may serve as smoking cessation/reduction aids.

Determination of 210Pb and 210Po in Brazilian cigarette tobacco

International Nuclear Information System (INIS)

Peres, A.C.; Hiromoto, G.

Cigarette smoking is one of the important pathways that could contribute to enhance the radiation dose to man, due to the relatively large concentrations of 210 Pb and 210 Po found in tobacco leaves. In this work, concentrations of these two radionuclides were determined in eight of the most commercialized cigarette brands produced in Brazil. The samples analyzed were bought randomly in the market. The 210 Pb was determined by counting the beta activity of the 210 Bi in a gas flow proportional detector, after radiochemical separation and precipitation of the PbCrO 4 . The 210 Po was determined by alpha spectrometry, using a surface barrier detector, after radiochemical separation and spontaneous deposition of Po in copper disk. The results showed concentrations ranging from 15,8 to 30,2 mBq per gram of dry tobacco for 210 Pb and from 18,8 to 27,4 mBq per gram of dry tobacco for 210 Po. Taking in account the experimental error of the measurements, radioactive equilibrium between 210 Pb and 210 Po is observed for all analyzed samples. This result was expected, since the delayed time from the harvest of tobacco leaves to the introduction of cigarettes in the market is enough to reach that equilibrium. Assuming a 20 cigarettes per day consumption, and a 10% of Pb and 20% of Po being inhaled by the primary smokers, it is obtained a value of yearly intake of 11,3 Bq of 210 Pb and 21,2 Bq of 210 Po, due to cigarette consumption. These values lead to an increment to the committed effective dose of 0,025 mSv year -1 and an increment to the probability of getting cancer of 1 x 10 -6 per year. (author)

Smoking is a global public health problem. For this reason, experts have called smoking dependence a global epidemic. Over the past 5 years, sales of electronic cigarettes, or e-cigarettes, have been growing strongly in many countries. Yet there is only partial evidence that e-cigarettes are beneficial for smoking cessation. In particular, although it has been proven that nicotine replacement devices may help individuals stop smoking and tolerate withdrawal symptoms, e-cigarettes' power to increase the quitting success rate is still limited, ranging from 5% to 20% dependent on smokers' baseline conditions as shown by a recent Cochrane review. Consequently, it is urgent to know if e-cigarettes may have a higher success rate than other nicotine replacement methods and under what conditions. Furthermore, the effects of the therapeutic setting and the relationship between individual characteristics and the success rate have not been tested. This protocol is particularly innovative, because it aims to test the effectiveness of electronic devices in a screening program (the COSMOS II lung cancer prevention program at the European Institute of Oncology), where tobacco reduction is needed to lower individuals' lung cancer risks. This protocol was designed with the primary aim of investigating the role of tobacco-free cigarettes in helping smokers improve lung health and either quit smoking or reduce their tobacco consumption. In particular, we aim to investigate the impact of a 3-month e-cigarettes program to reduce smoking-related respiratory symptoms (eg, dry cough, shortness of breath, mouth irritation, and phlegm) through reduced consumption of tobacco cigarettes. Furthermore, we evaluate the behavioral and psychological (eg, well-being, mood, and quality of life) effects of the treatment. This is a prospective, randomized, placebo-controlled, double-blind, three-parallel group study. The study is organized as a nested randomized controlled study with 3 branches: a

Following the passage of the Family Smoking Prevention and Tobacco Control Act in 2009, flavoured cigarettes, including clove cigarettes, were banned based on the rationale that such cigarettes appealed to youth. However, the ban on characterising flavours was not extended to cigars. This study reviewed industry documents from Kretek International, the parent company behind Djarum clove cigars, to document the changes in their marketing and production strategies following the flavour ban on cigarettes. To assess sales trends following the ban, data for clove cigar sales in the USA from 2009 to 2012 were analysed using Nielsen's Convenience Track retail scanner database. Additionally, data on tobacco imports to the USA from Indonesia were obtained from the USDA Foreign Agricultural Service's Global Agricultural Trade System for the years 2008-2012. In anticipation of Food and Drug Administration's (FDA) flavour ban on cigarettes and recognising the regulatory advantages of cigars, Kretek International began developing Djarum clove cigars in 2007. Immediately following the flavour ban, sales of this product increased by more than 1400% between 2009 and 2012. During this same period, tobacco imports to the USA from Indonesia, a leader in clove tobacco production, shifted from cigarettes to almost exclusively cigars. Kretek International, like other tobacco manufacturers, manipulated its products following the Family Smoking Prevention and Tobacco Control Act as a way to capitalise on regulatory loopholes and replace its now banned clove cigarettes. As a result, consumption of the company's Djarum clove cigars increased exponentially in recent years. Published by the BMJ Publishing Group Limited.

To assess dependence levels in users of e-cigarettes, and compare them with dependence levels in users of nicotine gums and tobacco cigarettes. Self-reports from cross-sectional Internet and mail surveys. Comparisons of: (a) 766 daily users of nicotine-containing e-cigarettes with 30 daily users of nicotine-free e-cigarettes; (b) 911 former smokers who used the e-cigarette daily with 451 former smokers who used the nicotine gum daily (but no e-cigarette); (c) 125 daily e-cigarette users who smoked daily (dual users) with two samples of daily smokers who did not use e-cigarettes (2206 enrolled on the Internet and 292 enrolled by mail from the general population of Geneva). We used the Fagerström test for nicotine dependence, the nicotine dependence syndrome scale, the cigarette dependence scale and versions of these scales adapted for e-cigarettes and nicotine gums. Dependence ratings were slightly higher in users of nicotine-containing e-cigarettes than in users of nicotine-free e-cigarettes. In former smokers, long-term (>3 months) users of e-cigarettes were less dependent on e-cigarettes than long-term users of the nicotine gum were dependent on the gum. There were few differences in dependence ratings between short-term (≤3 months) users of gums or e-cigarettes. Dependence on e-cigarettes was generally lower in dual users than dependence on tobacco cigarettes in the two other samples of daily smokers. Some e-cigarette users were dependent on nicotine-containing e-cigarettes, but these products were less addictive than tobacco cigarettes. E-cigarettes may be as or less addictive than nicotine gums, which themselves are not very addictive. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

In remote Indigenous Australian communities measuring individual tobacco use can be confounded by cultural expectations, including sharing. We compared self-reported tobacco consumption with community-level estimates in Arnhem Land (Northern Territory). In a cross-sectional survey in three communities (population 2319 Indigenous residents, aged ≥16 years), 400 Indigenous residents were interviewed (206 men, 194 women). Eight community stores provided information about tobacco sold during the survey. To gauge the impact of 255 non-Indigenous residents on tobacco turnover, 10 were interviewed (five men, five women). Breath carbon monoxide levels confirmed self-reported smoking. Self-reported number of cigarettes smoked per day was compared with daily tobacco consumption per user estimated using amounts of tobacco sold during 12 months before the survey (2007-2008). 'Lighter smokers' (Indigenous study participants, 305 (76%) used tobacco; four chewed tobacco. Of 301 Indigenous smokers, 177 (58%) provided self-reported consumption information; a median of 11-11.5 cigarettes per day in men and 5.5-10 cigarettes per day in women. Men were three times (odds ratio=2.9) more likely to be 'heavier smokers'. Store turnover data indicated that Indigenous tobacco users consumed the equivalent of 9.2-13.1 cigarettes per day; very similar to self-reported levels. Sixty per cent (=6/10) of non-Indigenous residents interviewed were smokers, but with little impact on tobacco turnover overall (2-6%). Smoking levels reported by Indigenous Australians in this study, when sharing tobacco was considered, closely reflected quantities of tobacco sold in community stores. © 2010 Australasian Professional Society on Alcohol and other Drugs.

Given the rapid increase in e-cigarette use, it is important to understand factors that may contribute to their initiation and maintenance. Because gender differences in tobacco use, product preferences, and expectancies are well established, similar gender differences may exist with e-cigarettes. The aim of this study was to identify gender differences among e-cigarette users in patterns of use, reasons for initiation and maintenance, and outcome expectancies regarding e-cigarettes. Participants (N=1815) completed an online survey from August through November, 2013. We assessed sociodemographics, smoking and e-cigarette history and use, and expectancies about e-cigarettes. We found gender differences in type of e-cigarette used, flavors used, nicotine dosage, source of information about e-cigarettes, place of purchase, and use of e-cigarettes where smoking is prohibited. In addition, males were more likely to report initiating e-cigarette use to quit smoking due to health concerns, whereas females were more likely to report initiation based on recommendations from family and friends. Males reported higher attributions for maintenance of e-cigarette use related to positive reinforcement (enjoyment), whereas females reported higher negative reinforcement attributions (stress reduction or mood management). Males reported more positive expectancies about e-cigarettes, including taste, social facilitation, and energy, whereas women rated e-cigarettes higher for weight control. Males also reported greater addiction-related e-cigarette expectancy than females. Many of the gender differences with e-cigarettes parallel those previously found with traditional cigarette smoking. Although effect sizes associated with these differences were small, the results may help advance research and intervention development with respect to e-cigarette initiation, maintenance and cessation.

Excise duties on roll-your-own (RYO) tobacco, which are generally based on RYO cigarettes containing 1 g of tobacco, are lower than duties on factory-made (FM) cigarettes. This provides a price incentive for smokers to switch to RYO, the use of which is increasing across Europe. To effectively approximate duties on the two types of products, accurate data on the weight of RYO cigarettes are required. We provide updated information on RYO use and RYO cigarette weight across Europe. From a representative face-to-face survey conducted in 2010 in 18 European countries (Albania, Austria, Bulgaria, Czech Republic, Croatia, England, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Poland, Portugal, Romania, Spain and Sweden), we considered data from 5158 current smokers aged 15 years or above, with available information on daily consumption of FM and RYO cigarettes separately. In Europe, 10.4% of current smokers (12.9% of men and 7.5% of women) were 'predominant' RYO users (i.e. >50% of cigarettes smoked). This proportion was highest in England (27.3%), France (16.5%) and Finland (13.6%). The median weight of one RYO cigarette is 0.75 g (based on 192 smokers consuming exclusively RYO cigarettes). The proportion of RYO smokers is substantial in several European countries. Our finding on the weight of RYO cigarettes is consistent with the scientific literature and industry documents showing that the weight of RYO cigarettes is substantially lower than that of FM ones. Basing excise duties on RYO on an average cigarette weight of 0.75 g rather than 1 g would help increase the excise levels to those on FM cigarettes.

Three categories of e-cigarette brands have emerged within the US market: e-cigarette brands developed by cigarette manufacturers, brands acquired by cigarette manufacturers and brands with no cigarette manufacturer affiliation. In the absence of federal regulatory oversight of e-cigarettes, we assessed differences in e-cigarette products and sales practices across these categories. Brand websites for top-selling e-cigarette brands from each of these categories were examined in October of 2015 to compare website access restrictions, online sales practices and products sold, including e-cigarette model type (eg, 'cigalike' vs advanced systems) and options available (eg, flavoured, nicotine free). Website access to brands developed by cigarette manufacturers was restricted to users aged 21 years or older, and one website required user registration. In addition, these brands were exclusively reusable/rechargeable 'cigalikes.' Limited flavour options were available for these products, and nicotine-free options were not sold. In contrast, brands acquired by cigarette manufacturers and brands with no cigarette manufacturer affiliation generally required website visitors to be 18, offered a nicotine-free option, and most offered disposable products and an array of flavoured products (eg, fruit/candy flavours). This exploratory study finds differences in e-cigarette products and sales practices across these three e-cigarette brand categories, with brands developed by cigarette manufacturers adopting a particularly distinctive product and sales strategy. Anticipated regulation of e-cigarettes in the USA may be influencing these product and sales decisions. Published by the BMJ Publishing Group Limited.

Questionnaires are widely used to obtain information on health-related behaviour, and they are more often than not the only method that can be used to assess the distribution of behaviour in subgroups of the population. No validation studies of reported consumption of tobacco or alcohol have been published from circumpolar indigenous communities. The purpose of the study is to compare information on the consumption of tobacco and alcohol obtained from 3 population surveys in Greenland with import statistics. Estimates of consumption of cigarettes and alcohol using several different survey instruments in cross-sectional population studies from 1993-1994, 1999-2001 and 2005-2010 were compared with import statistics from the same years. For cigarettes, survey results accounted for virtually the total import. Alcohol consumption was significantly under-reported with reporting completeness ranging from 40% to 51% for different estimates of habitual weekly consumption in the 3 study periods. Including an estimate of binge drinking increased the estimated total consumption to 78% of the import. Compared with import statistics, questionnaire-based population surveys capture the consumption of cigarettes well in Greenland. Consumption of alcohol is under-reported, but asking about binge episodes in addition to the usual intake considerably increased the reported intake in this population and made it more in agreement with import statistics. It is unknown to what extent these findings at the population level can be inferred to population subgroups.

The emerging trends and rapid growth of electronic cigarettes (e-cigarettes) among adolescents are being monitored closely. The trends are critical as policy to prevent uptake among adolescents is considered. The purpose of this study is to describe the prevalence of e-cigarette use and potential correlates for use. Associations between e-cigarettes, cigarettes, and hookah are assessed. This study used data from the 2013 Florida Youth Tobacco Survey. Prevalence estimates were calculated in 2014 and differences were determined based on CIs. Adjusted logistic regression models were used to identify correlates of e-cigarette use among participants based on demographic and other tobacco products used. There were no sex differences in middle school, whereas male high school students reported higher use than their female counterparts. Cigarette smoking and hookah use were significantly associated with ever and current e-cigarette use among both middle and high school students. Although e-cigarettes are being assessed as a potential replacement product for traditional tobacco, evidence from this study indicates the possibility of multiple product use among adolescents. E-cigarettes are not only associated with traditional cigarettes, but also with hookahs, a similar emerging product that offer tobacco flavors that may appeal to adolescents. Notably, many e-cigarette users also reported no cigarette or hookah use. Copyright © 2015 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

Development of nitroxide radicals–containing polymer for scavenging reactive oxygen species from cigarette smoke

We developed a nitroxide radicals–containing polymer (NRP), which is composed of poly(4-methylstyrene) possessing nitroxide radicals as a side chain via amine linkage, to scavenge reactive oxygen species (ROS) from cigarette smoke. In this study, the NRP was coated onto cigarette filters and its ROS-scavenging activity from streaming cigarette smoke was evaluated. The intensity of electron spin resonance signals of the NRP in the filter decreased after exposure to cigarette smoke, indicating consumption of nitroxide radicals. To evaluate the ROS-scavenging activity of the NRP-coated filter, the amount of peroxy radicals in an extract of cigarette smoke was measured using UV–visible spectrophotometry and 1,1-diphenyl-2-picrylhydrazyl (DPPH). The absorbance of DPPH at 517 nm decreased with exposure to cigarette smoke. When NRP-coated filters were used, the decrease in the absorbance of DPPH was prevented. In contrast, both poly[4-(cyclohexylamino)methylstyrene]- and poly(acrylic acid)-coated filters, which have no nitroxide radical, did not show any effect, indicating that the nitroxide radicals in the NRP scavenge the ROS in cigarette smoke. As a result, the extract of cigarette smoke passed through the NRP-coated filter has a lower cellular toxicity than smoke passed through poly[4-(cyclohexylamino)methylstyrene]- and poly(acrylic acid)-coated filters. Accordingly, NRP is a promising material for ROS scavenging from cigarette smoke. (papers)

Illicit Cigarette Trade in Five South American Countries: A Gap Analysis for Argentina, Brazil, Chile, Colombia and Peru.

Due to its nature, it is very hard to measure tobacco illicit trade in any product. In the case of Latin American countries, there is scant information on the magnitude and characteristics of this trade in the case of cigarettes. The goal of this article is to provide estimates on the evolution of the illicit cigarette trade in five South American countries: Argentina, Brazil, Chile, Colombia and Peru. Gap analysis estimates for cigarette tax evasion/avoidance (a comparison on the evolution of the difference between registered cigarette sales and measured population consumption) is developed for Argentina, Brazil, Chile, Colombia and Peru. Nationally representative surveys, conducted regularly, are used to measure population consumption. Confidence intervals constructed by bootstrapping sample estimates are generated in order to statistically evaluate the evolution of the gap. Cigarette illicit trade has increased as a percentage of total sales in Brazil in recent years. In the case of Argentina, after a relative decrease between 2005 and 2009 it seems to have stabilized. There is no statistical evidence to argue that there has been an increase of cigarette illicit trade in Chile, Colombia and Peru, despite substantial price increases in Chile and tax increase in both Colombia and Peru. Using simple statistical methods, it is possible to assess the trend in tobacco illicit trend over time to better inform policy-makers. Getting reliable and regular population consumption surveys can also help to track tobacco illicit trade. Claims by tobacco industry of a positive association between price/tax changes and illicit trade are unsubstantiated. Evolution of cigarette illicit trade in five Latin American countries show different trajectories, not in line with tobacco industry estimates, which highlight the importance of producing solid, independent estimates. There are inexpensive methodologies that can provide estimates of the evolution of the relative importance of

Not much is currently understood regarding the contexts of cigarette and e-cigarette use among dual users. Proper application of e-cigarettes to smoking cessation or tobacco harm reduction would require an understanding of when and why dual users use cigarettes versus e-cigarettes. This study sought to elucidate the contexts of cigarette versus e-cigarette use among dual users. Twelve focus group discussions were conducted with 62 young adult current daily e-cigarette users [63% men; mean age = 25.1 (Standard Deviation = 5.5)]. Almost all participants either concurrently smoked cigarettes or had been recent dual users. Data were analyzed following principles of inductive deduction. Results indicated that dual users' use of cigarettes is influenced by particular activities (e.g., before/after eating), strong craving or need for stimulation (e.g., in response to stress), places/situations (e.g., when cigarette smokers are nearby; outdoors), use of other substances (alcohol, coffee), and unavailability of an e-cigarette when needed. In addition to particular activities and places/situations that are conducive to e-cigarette use, use of e-cigarette when cigarette is not available or where cigarette smoking is not permitted emerged as contexts specific to e-cigarette use. For habitual cigarette smokers wanting to quit tobacco smoking, switching over completely to e-cigarettes may require skills of cognitive-behavioral management. Future research needs to ascertain the characteristics of dual users who use e-cigarettes as cessation aids versus as cigarette alternative when cigarette is unavailable or smoking is not permitted.
