Effects of smoking on health:
The data continue to accumulate an increasing number of effects of smoking on health. A report of the Surgeon General of the United States, report, The Health Consequences of Smoking, concluded that smoking affects almost every organ in the body. It causes disease and it weakens the smoker's health, several organs of the latter may be affected simultaneously. Laboratory research can increasingly understand how to develop these diseases at the molecular and cellular levels.
Morbidity:
According to the Surgeon General's report, it is shown that smoking increases the risk of several types of cancer in addition to well-known, lung (85% of cases, up to twenty times more likely): bladder neck the uterus, esophagus, kidney, larynx, mouth, pharynx, leukemia, stomach and pancreas. Furthermore, the data suggest, however, without being conclusive, that the risks are also increased for colorectal cancer and liver cancer. The risk of cancer increases with the number of cigarettes smoked and the number of years during which the consumer has continued. These risks of smoking are not surprising given the fact that cigarette smoke is made up of about four thousand chemicals, including sixty are considered carcinogens or suspected to be.
The increased risk of cardiovascular disease are also well documented: aortic aneurysm, atherosclerosis, stroke and coronary heart disease (risk of death from this disease multiplied by four). A quarter of ischemic heart disease are caused by tobacco.
Disease and lung problems are obviously increased by smoking: chronic obstructive pulmonary disease (chronic bronchitis and emphysema, 75% of cases are related to smoking), pneumonia, reduced lung capacity in children whose mothers smoked during pregnancy reduced in children and adolescent smoking lung growth, reduced lung capacity in young adults and adults, chronic cough, wheezing, asthma in children and adolescents.
Smoking affects maternity and increases the risk of reduced fertility, sudden infant death syndrome in infants of mothers who smoked during and after pregnancy (three to four times more likely), low birth weight and preterm delivery. A report by the British Medical Association also shows the deleterious effects of smoking on sexual health and reproductive health.
Mortality:
According to the World Health Organization, someone dies from a tobacco-related disease every 6.5 seconds. Worldwide, more than 5 million people die each year, and the number of victims expected to double over the next twenty years to nearly 10 million in 2020 (source: WHO, deadly tobacco in all its forms this Link opens in a new window.), the epidemic continues to spread, and especially in developing countries, where 85% of smokers live. Half of young smokers will die from a disease caused by tobacco, half of them dying before the age of 70 and losing on average 21 years of life. In a cohort of 34,439 male British doctors born between 1900 and 1930, smokers have died on average ten years earlier than non-smokers. The number of premature deaths (before age 70) is about two times higher in smokers than in lifelong non-smokers for life, for both men (2.3) than in women (1, 9). Among smokers in Canada, life expectancy at age 35 is reduced by about 10-20%. Even a reduced daily consumption of cigarettes (one to four) may increase mortality.
More people die each year from smoking that met the following causes: alcoholic liver disease, road accidents, suicides and homicides. Smoking is by far the leading preventable cause of death.
The effects of smoking observed at some point resulting in consumption that prevailed a few decades earlier, given the latency period between the two phenomena. So, despite the decline in smoking rates in Quebec over the past decade, there is every reason to believe that the current curve of mortality associated with tobacco use was not seriously bent accordingly.
