The costs of smoking are extensive, not only in fiscal terms but also in terms of human suffering. A review of several major public policies reveals that concerted efforts by all levels of government and by the public can have an effect on the rate of consumption of tobacco. Specifically, increases in price through taxation, anti-smoking messages, restrictions on smoking behaviour and increased public pressure are effective in reducing smoking. Serious joint efforts in the area of public policy should be pursued to control the effects of this hazardous practice in Canada. 相似文献

Tobacco-related mortality is one of the biggest killers in American medicine. Evidence suggests that if adolescents can be kept tobacco-free, most will never start using tobacco. Therefore, tobacco control policies directed at the youth population could provide an effective method for sustaining long-term reductions in smoking in all segments of the population. Many forms of tobacco control policies have been implemented including restrictive laws, public campaigns, and taxation duties; there has been disagreement over which is most effective. We investigate the efficacy of various methods of tobacco control in youth and present a review of the published evidence. Econometric data for both youth access restrictions and environmental tobacco smoke restrictions afford ambiguous results. Results vary in a continuum from a moderate negative effect toward, ironically, a marginal positive effect on smoking. While information dissemination policies may be somewhat effective on the onset, they are limited in their effect and eventually diminish over time. We conclude that increases in price affect teen smoking to a great degree. Most estimates show that for a 10 percent increase in prices, which could be implemented by a tax per pack, a 15 percent decrease in cigarettes consumed could be accomplished. Taxation policies are an effective means of preventative medicine. 相似文献

Background
Increases in taxation can contribute to smoking control. In the early 1990’s, tobacco smuggling rates in Canada increased dramatically. Governments responded with a substantial reduction in taxes on tobacco products. This study examines the impact of these tax changes on smoking in youth in Canada.Methods
Data on smoking from three consecutive cycles of the Canadian Community Health Surveys were combined and analyzed using a reconstructed cohort approach. Age, sex and calendar year specific rates of smoking experimentation and the onset of daily smoking were estimated for youth. Estimates apply to the entire Canadian population.Results
There was a strong increase in smoking in youth in the years following the reduction in tobacco taxes. The increase was stronger in women. The rates returned to pre-1990 rates by about 2002. The number of excess daily smokers for people born between 1977 and 1985 that can be linked to the taxation reduction is about 190,000.Interpretation
There is strong evidence that reduction of tobacco taxes to combat smuggling had an adverse impact on smoking rates in youth. 相似文献4.
ObjectiveTo quantify the effects of smoke-free workplaces on smoking in employees and compare these effects to those achieved through tax increases.DesignSystematic review with a random effects meta-analysis.SettingWorkplaces in the United States, Australia, Canada, and Germany.ParticipantsEmployees in unrestricted and totally smoke-free workplaces.ResultsTotally smoke-free workplaces are associated with reductions in prevalence of smoking of 3.8% (95% confidence interval 2.8% to 4.7%) and 3.1 (2.4 to 3.8) fewer cigarettes smoked per day per continuing smoker. Combination of the effects of reduced prevalence and lower consumption per continuing smoker yields a mean reduction of 1.3 cigarettes per day per employee, which corresponds to a relative reduction of 29%. To achieve similar reductions the tax on a pack of cigarettes would have to increase from $0.76 to $3.05 (€0.78 to €3.14) in the United States and from £3.44 to £6.59 (€5.32 to €10.20) in the United Kingdom. If all workplaces became smoke-free, consumption per capita in the entire population would drop by 4.5% in the United States and 7.6% in the United Kingdom, costing the tobacco industry $1.7 billion and £310 million annually in lost sales. To achieve similar reductions tax per pack would have to increase to $1.11 and £4.26.ConclusionsSmoke-free workplaces not only protect non-smokers from the dangers of passive smoking, they also encourage smokers to quit or to reduce consumption.

In 1951 the British Medical Association forwarded to all British doctors a questionnaire about their smoking habits, and 34440 men replied. With few exceptions, all men who replied in 1951 have been followed for 20 years. The certified causes of all 10 072 deaths and subsequent changes in smoking habits were recorded. The ratio of the death rate among cigarette smokers to that among lifelong non-smokers of comparable age was, for men under 70 years, about 2:1, while for men over 70 years it was about 1-5:1. These ratios suggest that between a half and a third of all cigarette smokers will die because of their smoking, if the excess death rates are actually caused by smoking. To investigate whether this is the case, the relation of many different causes of death to age and tobacco consumption were examined, as were the effects of giving up smoking. Smoking caused death chiefly by heart disease among middle-aged men (and, with a less extreme relative risk, among old men,) lung cancer, chronic obstructive lung disease, and various vascular diseases. The distinctive features of this study were the completeness of follow-up, the accuracy of death certification, and the fact that the study population as a whole reduced its cigarette consumption substantially during the period of observation. As a result lung cancer grew relatively less common as the study progressed, but other cancers did not, thus illustrating in an unusual way the causal nature of the association between smoking and lung cancer. 相似文献

OBJECTIVE: To assess the effect of the tobacco tax cuts made in 1994 on the smoking habits of Canadians. DESIGN: Population-based retrospective cohort study. DATA: Data from the Survey on Smoking in Canada conducted by Statistics Canada on 11,119 respondents 15 years of age and older, who were interviewed about their smoking habits on 4 occasions, approximately every 3 months from January 1994 to February 1995. OUTCOME MEASURES: Changes in smoking prevalence, incidence, quit rates and mean number of cigarettes smoked per day in the provinces where tobacco taxes were cut and in those where taxes were not cut. RESULTS: During the survey, smoking prevalence decreased in all provinces, whether or not cigarette taxes had been cut. However, the prevalence of smoking was greater in the provinces where tobacco taxes had been cut than in those where they had not, and this difference increased from 2.0% at the beginning of the survey to 3.4% by the end (p < 0.001). In addition, rates of starting cigarette smoking were higher and smoking quit rates were lower in the provinces where taxes had been cut than in those where taxes had not been cut. CONCLUSION: Although smoking rates are declining in Canada, tobacco tax cuts appear to have slowed the rate of decline by inducing more nonsmokers to take up smoking and leading fewer smokers to quit. 相似文献

Cigarette smoking is the leading cause of preventable death and disease in Canada, accounting for some 30 000 deaths annually. This enormous health cost to Canadians has led the Canadian Medical Association (CMA) to promote initiatives regarding smoking prevention programs in schools, legislation to prevent smoking in government buildings and controls on smoking in private buildings, particularly places of work. The CMA recommends the prohibition of all forms of tobacco advertising/promotion in Canada, including advertising in conjunction with athletic events. The CMA also supports the taxation of tobacco products at a level to discourage their purchase, with revenue earmarked for health budgets, and the association is encouraging the federal government to develop alternative crop incentives for tobacco farmers. The norm of nonsmoking is a social attitude the CMA is working toward developing in all Canadians. 相似文献

To prevent "life style-related diseases", it is necessary to evaluate not only the factors directly related to sleep but also the relationship between sleep and other life style-related factors (such as smoking, alcohol drinking, food habits, and exercise routines). There have been no extensive studies conducted on these relationships. A survey was conducted on 2,000 employees of a large plant over a 6-year period to provide data that would allow one to analyze correlation between hours of sleep and other life style factors, such as smoking, alcohol drinking, dietary habit, and exercise. It focused on a serial evaluation, with special reference to the correlation between sleep and smoking and drinking habits, exercise, and food habits. In relation to smoking or an alcohol drinking habit, no significant correlation was found between those who did not get enough sleep and those who got adequate sleep. For the dietary habits, the group with insufficient hours of sleep was related to a less than satisfactory frequency of meal taking, irregularity of eating, snacking habits, excessive seasoning of food, and consumption of insufficient quantities of vegetables. Conversely, it was recognized that those who have satisfactory food habits are more likely to enjoy an appropriate amount of sleep. Those who fail to get sufficient sleep engage in food habits that are more likely to cause life style-related diseases. 相似文献

This article reviews the cultural history of man's relationship with tobacco and the steps in the discovery of tobacco addiction. Nicotine dependence (ND) or nicotine addiction (NA), among other forms of drug addiction, continues to be a significant public health problem in the world, as it is associated with major severe diseases such as cardiovascular disease and cancer. Evidence for a genetic influence on smoking behavior and ND has prompted a search for susceptibility genes. Proof has recently accumulated that single nucleotide polymorphisms (SNPs) in the genetic region encoding the nicotinic acetylcholine receptor (nAChR) subunits α5, α3, and β4 are associated with smoking and ND. In this review, we consider tobacco as the archetype of substance addiction and describe the evolution of the tobacco habit from elite users to lower socioeconomic abusers (by mass marketing and specific targeting of vulnerable groups by the tobacco industry) to exemplify detrimental behavior with major threats to public health. Finally, we discuss the reasons for the difficulty of quitting addictions/habits and highlight possible solutions. 相似文献

Tax levels have important effects on cigarette prices and tax revenues. Over 70p of every pound spent on tobacco goes to the Chancellor of the Exchequer, yielding over 5 billion pounds. But the value of tobacco tax revenues have generally fallen--by 1986 they were 10% lower than at their peak in 1965, and tobacco revenue is becoming a smaller proportion of total tax receipts. The impact of a consistent increase in tobacco taxation is important in terms of reduced consumption (and harm to health) as well as in terms of reduced employment. Revenue may, however, increase in the short term. Finally, if the findings of Townsend and Atkinson et al (see above) still apply then the distributive effects of increased taxation on the poor might be less than is sometimes feared. 相似文献

Evaluation of micronuclei frequency in the cultured peripheral blood lymphocytes of cancer patients before and after radiation treatment 总被引:7,自引:0,他引:7
The frequency of micronucleated binucleate lymphocyte (MNBNC) was determined in the peripheral blood lymphocytes of patients suffering from various types of cancer before the onset of radiation treatment, middle (mid-) of the treatment and after completion of the treatment (post-treatment). The frequency of micronuclei increased significantly in the pretreatment sample of cancer patients when compared with the normal untreated healthy volunteers. During the middle of the radiotherapy an approximate two or > two-fold increase was observed in the micronuclei frequency in most of the patients when compared with the concurrent pretreatment samples. Immediately after the completion of treatment, the frequency of micronuclei further increased, and this increase was significantly higher than that of pretreatment and mid-treatment samples. Out of 27 patients analyzed, only nine patients did not have any history of smoking, tobacco chewing or alcohol consumption, while the remaining 18 patients had a history of either smoking, tobacco chewing or alcohol consumption or combination of two or all habits at the time of blood collection. 相似文献

The smoking habits of 1501 cigarette smokers attending 28 general practitioners in five group practices in London were assessed. Prevalence of smoking, daily cigarette consumption, and the use of cigars, untipped cigarettes, and hand-rolled cigarettes were lower in the women. After controlling for consumption the proportions of men and women who smoked every day were similar. Women who smoked 20 or more a day were similar to men in their self-reported inhaling habits and use of low-nicotine cigarettes. The results suggest that women differ from men in those aspects of smoking that are determined predominantly by social factors but that their smoking habits become similar when pharmacological motivation takes over. This apparently occurs when consumption reaches about 20 cigarettes a day, when smoking almost inevitably becomes a regular event and the sex differences disappear. 相似文献

Four smokers were chosen for their different smoking habits, and their declared cigarette consumption confirmed by urinary measurement of nicotine and its metabolites. The promutagenicity of their urine was evaluated by the Ames test, modified according to Kado et al. (Mutation Res., 31 (1983) 25–32) after extraction on XAD2 Amberlite resin. The different Salmonella typhimurium strains TA 98, YG 1021 and YG 1024 were compared to determine the presence of amino aromatic compounds in the urine of smokers of blond and black tobacco. The strain YG 1024 shows higher mutagenicity than TA 98 for extracts from the smoker's urine and more particularly from black tobacco smokers. In addition, the pretreatment of urine by external enzymatic systems (β-glucuronidase or arylsulfatase) reveals the presence in the urine of glucurono- and sulfoconjugated forms of promutagens, including amino aromatic compounds. 相似文献

Despite increased social awareness, marketing restraints, tobacco taxation, and available smoking cessation rehab programs, active and passive smoking remain a worldwide challenging epidemic and a key risk factor for cardiovascular diseases development. Although cardiovascular (CV) protection is more pronounced in women than in men due to estrogenic effects, tobacco cigarette smoking exposure seems to alter this protection by modulating estrogen actions via undefined mechanisms. Premenopausal cigarette smoking women are at higher risk of adverse CV effects than non-smokers. In this study, we investigated the impact of cigarette smoking on early CV injury after myocardial infarction (MI) in non-menopausal female mice. Aortic arch calcification, fibrosis, reactive oxygen species, and gene expression of inflammatory and calcification genes were exaggerated in mice exposed to cigarette smoke (CS). These findings suggest that aortic injury following MI, characterized by vascular smooth muscle cells transdifferentiation, calcification, inflammation, and collagen deposition but not cardiac dysfunction is exacerbated with CS exposure. The novel findings of this study highlight the importance of aortic injury on short and long-term prognosis in CS-exposed MI females. Linking those findings to estrogen alteration is probable and entails investigation. 相似文献

Variations in tobacco-related cancers, incidence and prevalence reflect differences in tobacco consumption in addition to genetic factors. Besides, genes related to lung cancer risk could be related to smoking behavior. Polymorphisms altering DNA repair capacity may lead to synergistic effects with tobacco carcinogen-induced lung cancer risk. Common problems in genetic association studies, such as presence of gene-by-environment (G x E) correlation in the population, may reduce the validity of these designs. The main purpose of this study was to evaluate the independence assumption for selected SNPs and smoking behaviour in a cohort of 320 healthy Spanish smokers. We found an association between the wild type alleles of XRCC3 Thr241Met or KLC3 Lys751Gln and greater smoking intensity (OR = 12.98, 95% CI = 2.86–58.82 and OR=16.90, 95% CI=2.09-142.8; respectively). Although preliminary, the results of our study provide evidence that genetic variations in DNA-repair genes may influence both smoking habits and the development of lung cancer. Population-specific G x E studies should be carried out when genetic and environmental factors interact to cause the disease. 相似文献

Background
We simulated tobacco control and pharmacological strategies for preventing cardiovascular deaths in India, the country that is expected to experience more cardiovascular deaths than any other over the next decade.Methods and Findings
A microsimulation model was developed to quantify the differential effects of various tobacco control measures and pharmacological therapies on myocardial infarction and stroke deaths stratified by age, gender, and urban/rural status for 2013 to 2022. The model incorporated population-representative data from India on multiple risk factors that affect myocardial infarction and stroke mortality, including hypertension, hyperlipidemia, diabetes, coronary heart disease, and cerebrovascular disease. We also included data from India on cigarette smoking, bidi smoking, chewing tobacco, and secondhand smoke. According to the model''s results, smoke-free legislation and tobacco taxation would likely be the most effective strategy among a menu of tobacco control strategies (including, as well, brief cessation advice by health care providers, mass media campaigns, and an advertising ban) for reducing myocardial infarction and stroke deaths over the next decade, while cessation advice would be expected to be the least effective strategy at the population level. In combination, these tobacco control interventions could avert 25% of myocardial infarctions and strokes (95% CI: 17%–34%) if the effects of the interventions are additive. These effects are substantially larger than would be achieved through aspirin, antihypertensive, and statin therapy under most scenarios, because of limited treatment access and adherence; nevertheless, the impacts of tobacco control policies and pharmacological interventions appear to be markedly synergistic, averting up to one-third of deaths from myocardial infarction and stroke among 20- to 79-y-olds over the next 10 y. Pharmacological therapies could also be considerably more potent with further health system improvements.Conclusions
Smoke-free laws and substantially increased tobacco taxation appear to be markedly potent population measures to avert future cardiovascular deaths in India. Despite the rise in co-morbid cardiovascular disease risk factors like hyperlipidemia and hypertension in low- and middle-income countries, tobacco control is likely to remain a highly effective strategy to reduce cardiovascular deaths.

8-Hydroxydeoxyguanosine (8-OHdG) has been widely used as a biomarker of oxidative DNA damage in both animal and human studies. However, controversial data exist on the relationship between 8-OHdG formation and age, sex and tobacco smoking in humans, while few or no data are available on other exposures such as environmental tobacco smoke, alcohol, coffee and tea consumption. We investigated the level of 8-OHdG in DNA from peripheral leukocytes among 102 healthy adults living in Brescia province, North Italy, aged 25-45 (mean: 35.2 years), of which 51 were males. 8-OHdG levels expressed as a ratio to total deoxyguanosine (8-OHdG/106 dG) in DNA showed wide interindividual variation, the highest value (63.8) being 6. 2-fold greater than the lowest (10.3). Current smokers showed lower mean 8-OHdG values than subjects who never smoked (29.3 and 34.0, respectively, p<0.05), and an inverse relationship was found between 8-OHdG and lifetime smoking, which was independent of age, sex and body mass index. An inverse relationship was also found with coffee drinking while no association was observed with alcohol and tea consumption, exposure to environmental tobacco smoke and use of vitamins in all subjects, and with use of oral contraceptives in females. The inverse relationship between smoking status and 8-OHdG levels could be explained by the presence of efficient repair processes for the oxidative damage induced by smoking. In this study, the smokers were relatively young (77% were less than 40 years) and only 7% smoked 30 or more cigarettes a day. In conclusion, it would appear that 8-OHdG levels in leukocytes may not provide a sensitive marker of exposure to tobacco smoking. 相似文献

Background
Large state tobacco control programs have been shown to reduce smoking and would be expected to affect health care costs. We investigate the effect of California''s large-scale tobacco control program on aggregate personal health care expenditures in the state.Methods and Findings
Cointegrating regressions were used to predict (1) the difference in per capita cigarette consumption between California and 38 control states as a function of the difference in cumulative expenditures of the California and control state tobacco control programs, and (2) the relationship between the difference in cigarette consumption and the difference in per capita personal health expenditures between the control states and California between 1980 and 2004. Between 1989 (when it started) and 2004, the California program was associated with $86 billion (2004 US dollars) (95% confidence interval [CI] $28 billion to $151 billion) lower health care expenditures than would have been expected without the program. This reduction grew over time, reaching 7.3% (95% CI 2.7%–12.1%) of total health care expenditures in 2004.Conclusions
A strong tobacco control program is not only associated with reduced smoking, but also with reductions in health care expenditures. 相似文献20.
ObjectivesTo examine the behaviour and attitudes related to smoking and contraband tobacco products among smokers in two socially deprived areas.DesignCross sectional study with qualitative semistructured interviews, augmented by smokers'' day grid.SettingTwo areas of socioeconomic deprivation in Edinburgh.Participants50 male and 50 female smokers aged 25-40 years randomly selected from general practitioners'' lists from two health centres, each located in an area of deprivation.ResultsMost smokers wanted to quit but felt unable to because of the importance of smoking in their daily routine and their addiction to nicotine. Strategies for maintaining consumption levels in the face of increasing cigarette prices and low income included purchasing contraband cigarettes and tobacco. Vendors were contacted through social networks, family, and friends as well as common knowledge of people and places, particularly pubs where contraband was available. Most users of contraband considered that smugglers were providing a valuable service. Purchasing contraband tobacco was viewed as rational in the face of material hardship. Many smokers criticised the government for its high tobacco taxation and the lack of local services to help them to stop smoking.ConclusionsSmokers in deprived areas perceive a lack of support to help them to stop smoking. Cigarette and tobacco smuggling is therefore viewed positively by low income smokers as a way of dealing with the increasing cost of cigarettes. Smokers in areas of deprivation may thus show little support for tackling smuggling until more action is taken to deal with the material and personal factors that make it difficult for them to quit.
