Key Point Gender-specific smoking prevalence varies across the world. Background Worldwide, there are marked differences in smoking prevalence rates between men and women from country to country. For example, in South Africa, the Philippines, China, Iran, and Portugal, smoking prevalence is much lower in women than in men. In contrast, in the United States, Canada, Australia, and Iceland, the prevalence of smoking in men is only slightly higher than that in women. 1 Overall, the prevalence of smoking in men is declining. However, although smoking prevalence in women is declining in some countries, such as the United States, the United Kingdom, Australia, and Canada, in several southern, central, and eastern European countries, the rate of smoking in women is not in decline or is still increasing. 1 Reference 1.

Key Point Smoking prevalence rates in some countries are declining. However, mortality associated with smoking is increasing since smoking-related mortality is more closely associated with previous tobacco use rather than with current tobacco use. Background Using data from countries with the longest history of prevalent smoking, Lopez and colleagues constructed a 4-stage model of trends in smoking and subsequent smoking-related mortality. As the model illustrates, peaks in smoking prevalence in the population do not correspond to peaks in smoking-associated mortality, because current mortality rates are more closely related to previous smoking levels. Therefore, although in some regions, such as Western Europe and North America, smoking prevalence in men and women is on the decline, smoking-related mortality is increasing. Similarly, in areas like Asia, Central and South America, and North Africa, where smoking prevalence rates are increasing, the true impact in terms of smoking-related deaths will not be apparent for several decades. 1 In Asia, where one third of the world’s population lives, smoking-related mortality is expected to rise to 4.9 million people annually by 2020 if current smoking trends continue. 2 References 1.

Key Point In some countries, deaths attributable to tobacco account for >25% of total deaths in men aged > 35 years. Background The World Health Organization estimates that in the year 2000, 25% of total deaths in men aged >35 years in most countries in the Northern Hemisphere (including the United States, Canada, Cuba, Israel, Russia and all European nations) were tobacco related. In these countries, >25% of all men died from tobacco-related disorders. Twenty to 25% of women over the age of 35 died from tobacco-related disorders in the United States, Canada, and Cuba.

Key Point Tobacco puts a considerable burden on estimated annual costs to the economy worldwide. Background The estimated annual costs to the economy attributable to tobacco amounts to billions of US dollars. Examples of these costs range from a high of $184.5 billion in the US (total costs) to $284 million in Venezuela (direct healthcare costs only). Reference 1. Mackay J, Eriksen M, Shafey O.

Key Point Tobacco smoke exposes the body to 250 toxic or carcinogenic chemicals. Background Tobacco and tobacco smoke are known to be carcinogenic in humans.Tobacco smoke contains at least 4000 chemicals, at least 250 of which are toxic or carcinogenic. 1 For example, tobacco smoke contains irritants, such as acetone, ammonia, and toluene, found in paint stripper, cleaners, and solvents respectively; toxic heavy metals, such as cadmium, used in car batteries, and arsenic, used in poisons; and carbon monoxide, which is a hazardous component of exhaust fumes. 2 Although it is addictive, the nicotine found in tobacco is not a known carcinogen. 3 All cigarettes are toxic: the US Surgeon General’s report noted that smoking cigarettes with lower yields of tar and nicotine provides no health benefit. 4 References 1.

Key Point Smoking leads to diminished health status either by contributing to specific disease pathogenesis or by other nonspecific mechanisms. Background The pathological mechanisms of smoking include those specifically linked to the pathogenesis of diseases and those that are less specific. For example, smoking directly exposes lung cells to the potent mutagens and carcinogens which cause genetic changes in lung cells associated with lung cancer development. Smoking causes or contributes to endothelial injury and dysfunction, prothrombotic/fibrinolytic effects, inflammation, and adverse lipid profiles, which lead to cardiovascular disease. Finally, biological processes resulting in airway and alveolar injury and the accelerated decline in respiratory function caused by smoking contribute to the development of COPD. Reference 1.

Key Point Smoking is causally linked to a host of cardiovascular, respiratory, reproductive, and other conditions, as well as many types of cancer. The top 3 smoking attributable causes of death in the United States are lung cancer, ischemic heart disease, and chronic obstructive pulmonary disease (COPD). Background In 2004, the US Surgeon General published a report on the health effects of active smoking, focusing specifically on the evidence for a causal relationship between smoking and disease and death. According to the research summarized in the report, many serious conditions are caused by smoking, including cardiovascular, respiratory, reproductive, and other conditions, as well as cancer affecting diverse areas and organs of the body. In addition to the widely-known consequences of lung cancer and respiratory disease, smoking has been causally linked to such diverse morbidities as low-bone density, nuclear cataract, bladder cancer, and reduced fertility. 1 Other studies have linked smoking to vascular dementia 2 and peripheral arterial disease. 3 These conditions can affect young and middle-aged smokers and, in general, as a smoker’s age increases, the frequency of smoking-caused diseases rises. 1 References 1.

Key Point Tobacco smoke exposure in women during pregnancy is associated with serious consequences for infants and children. Background Exposure to tobacco smoke during pregnancy is associated with serious consequences for infants and children. Environmental smoke is associated with a 4-fold increased risk of low-birth weight and an increased risk of miscarriage, stillbirth, and sudden infant death syndrome (SIDS). 1,2 Annually in the United States during the 1990s, 9700–18,600 cases of low-birth weight infants were related to secondhand smoke. 3 In addition, lung function may be impaired, 2 and a possible association with cognitive and developmental syndromes may exist. 1,4 References 1.

Key Point Exposure to secondhand smoke is a serious health hazard; it increases lung cancer risk and worsens pre-existing respiratory diseases, including asthma, COPD, and emphysema. Background Secondhand smoke is a serious health hazard. According to the US Surgeon General’s 2006 report, there is no risk-free level of exposure to secondhand smoke. 1 This recent report, as well as data from the World Health Organization, estimate exposure to secondhand smoke in nonsmokers increases lung cancer risk by 20%–30%. 1,2 In adults, secondhand smoke exposure may also worsen existing lung disease, such as asthma, COPD, and emphysema. 2 Environmental smoking can induce and exacerbate asthma in children and can cause middle ear disease and otitis media. 2 A study in 52 countries showed that secondhand smoke increases risks of nonfatal acute myocardial infarction. The risk was increased in a graded manner, and the effect was most marked in subjects who never smoked and former smokers. The overall attributable risk was 15.4% in subjects who never smoked but are exposed for ≥1 hour per week to secondhand smoke compared with those who never smoked and never were exposed. 3 The 2006 US Surgeon General’s report notes that secondhand smoke exposure increases the risk of heart disease by 25%–30% in nonsmokers. 1 References 1.

Key Point Nicotine stimulates dopamine release in areas of the brain which is believed to result in the reward and satisfaction effect associated with smoking. Background After inhalation, nicotine preferentially binds to nicotinic acetylcholinergic (nACh) receptors located in the mesolimbic-dopamine system of the brain within a matter of seconds. Nicotine specifically activates 4 β 2 nicotinic receptors in the Ventral Tegmental Area (VTA) causing an immediate dopamine release at the Nucleus Accumbens (nAcc). 1 The dopamine release is believed to be a key component of the reward circuitry associated with cigarette smoking. 1 Reference 1.

Key Point Nicotine stimulates dopamine release in areas of the brain which is believed to result in the reward and satisfaction effect associated with smoking. Background Nicotine activates 4 2 nicotinic receptors that are localized to the neuronal bodies and terminal axons of the cells in the ventral tegmental area. This activation thereafter causes dopamine release at the nucleus accumbens, which is believed to result in the short-term reward/satisfaction effect associated with cigarette smoking.

Key Point Nicotine may cause up-regulation and desensitization of nicotinic receptors resulting in tolerance. Drops in nicotine levels in combination with up-regualtion and desentization can result in withdrawal and craving. Background Tolerance typically develops after longer-term nicotine use. Tolerance is related to both the up-regulation (increased number) and the desensitization of nicotinic receptors in the VTA that occurs as a result of long-term exposure to nicotine. A drop in nicotine level, in combination with the up-regulation and decreased sensitivity of the nicotinic receptor, can result in withdrawal symptoms and cravings. Smokers have the ability to self regulate nicotine intake by the frequency of cigarette consumption and the intensity of inhalation. In order to maintain a steady nicotine level, smokers generally titrate their smoking to achieve maximal stimulation and avoid symptoms of withdrawal and craving. References 1. Schroeder SA.

Key Point Nicotine addiction is a cycle which begins with nicotine binding to receptors in the brain causing the release of dopamine which in turn results in feelings of pleasure and calmness. Background The distribution of nicotine is very rapid. It can reach the brain within 10 to 20 seconds after inhaling cigarette smoke. 1 The binding of nicotine to its relevant receptors results in the release of multiple neurotransmitters, most critically dopamine. The release of dopamine in the nucleus accumbens neurons is thought to play a critical role in the addictive nature of nicotine. This release of dopamine requires binding of nicotine to 4 2 receptors. 1,2 Absorption of cigarette smoke from the lungs is rapid and complete, producing with each inhalation a high concentration of arterial nicotine that reaches the brain within 10 to 16 seconds. Nicotine has a terminal half-life in blood of 2 hours. Smokers therefore experience a pattern of repetitive and transient high blood nicotine concentrations from each cigarette. Nicotine’s activation of acetylcholinergic receptors induces the release of dopamine in the nucleus accumbens. This is similar to the effect produced by other drugs of misuse, such as amphetamines and cocaine. The symptoms of nicotine withdrawal are a major barrier to smoking cessation. Smokers start to experience impairment of mood and performance within hours of their last cigarette. These effects are completely alleviated by smoking a cigarette. Withdrawal symptoms include irritability, restlessness, feeling miserable, impaired concentration, and increased appetite, as well as craving for cigarettes. Cravings, sometimes intense, can persist for many months. References Jarvis MJ. Why people smoke. BMJ . 2004;328:277-279. Picciotto MR, Zoli M, Changeux J.

Key Point Quitting smoking reduces the risk of cardiovascular events. Background Quitting smoking substantially reduces the risk of all-cause mortality in individuals with CHD. A 2003 review of 9 electronic databases containing data from 1966 to 2003 for prospective cohort studies of patients with CHD, found that those who quit smoking had a 36% reduction in odds of all-cause mortality. 1 A reduction in risk of cardiac events is evident even among those who recently quit. In a German study of 967 patients aged 30–70 years who already had experienced an acute coronary event, Twardella et al found that the odds ratio (OR) for subsequent cardiovascular events decreased according to smoking status. Based on serum cotinine levels, patients were classified as never smokers, former smokers, and current smokers. Patients who said they smoked but who were negative for cotinine were classified as recent quitters. Assigning an OR of 1.00 for current smokers, the OR for recent quitters was 0.71, 0.64 for former smokers, and 0.44 for those who never smoked. 2 References 1. Critchley JA, Capewell S.
