Smoking does a lot of harm. It not only devours the health and life of smokers, but also pollutes the air and harms others.
1. Lung diseases: 38 kinds of toxic chemicals are released when cigarettes are burned, among which the harmful components are tar, carbon monoxide, nicotine, dioxins and * * * smoke. Tar is harmful to the mouth, throat, trachea and lungs. Tar in tobacco smoke is deposited on lung villi, which destroys the function of villi, increases phlegm and causes chronic bronchial diseases, such as tracheitis, emphysema, pulmonary heart disease and lung cancer. According to statistics, the proportion of smokers suffering from lung disease after 60 years old is 74%, while the proportion of non-smokers suffering from lung disease after 60 years old is only 4%, which is a shocking figure.
Second, cardiovascular diseases: carbon monoxide in cigarettes reduces the oxygen content in the blood, causing hypertension and other related diseases. Smoking will contract coronary artery, reduce or block supply, and lead to myocardial infarction. Smoking can increase adrenaline, make the heart beat faster, increase the heart load, affect blood circulation, and lead to more than 20 diseases such as cardiovascular and cerebrovascular diseases, diabetes, sudden death syndrome, decreased respiratory function and stroke.
Third, smoking causes cancer: The study found that smoking is the fastest and richest way to produce free radicals. Each cigarette will produce at least 654.38+10,000 free radicals, which will lead to cancer and many chronic diseases. Recently, a 50-year study was conducted on 35,000 smokers at Tidcliffe Hospital in Oxford, England. The results show that lung cancer, gastric cancer, pancreatic cancer, bladder cancer, liver cancer, oral cancer and sinus cancer are "significantly related" to smoking. Why smokers catch a cold easily is because the activity of lymphocytes in the human body decreases, leading to cancer. In view of the three major factors leading to smoking and cancer, the sooner you quit smoking, the better.
Fourth, smoking can also lead to osteoporosis and early menopause. Smoking can make men lose their sexual and reproductive functions. Smoking in pregnant women will lead to premature delivery and underweight of the fetus, and the probability of miscarriage will increase. Smoking makes teeth yellow, which makes bad breath easy. Smoking harms people, and the harm of passive smokers is five times that of smokers. For the health of you and your family, you should quit smoking as soon as possible.
Fifth, the harm of smoking to intelligence. Smoking will affect people's attention. Some people think that smoking can refresh the mind, eliminate fatigue and inspire, which is totally unreasonable. Experiments show that smoking seriously affects people's intelligence and memory, thus reducing the efficiency of work and study.
Smoking is harmful to nothing. 53% of children in China smoke passively, which is even more harmful and prone to pneumonia, bronchitis, severe asthma and other diseases. If the current smoking situation continues, children's intellectual development, families and individuals who smoke will pay a huge price.
Question 2: What is the average life expectancy of smokers? Smoking and life span have not been accurately investigated, but it can cause lung disease or cancer, thus shortening life span.
Question 3: How much life expectancy will smoking reduce? A cigarette shortens life 1 1 min.
According to a new study, smoking can shorten people's life span 1 1 minute. If you smoke a pack of 20 cigarettes a day, it may reduce people's life expectancy by about 3 hours and 40 minutes. This estimate is based on people who started smoking at the age of 17 and died at an average age of 7 1 7. Suppose he smokes 15 cigarettes a day like the average British addict, he will consume 3 1 1688 cigarettes in his life. On average, smokers die six and a half years earlier than non-smokers.
A similar study decades ago concluded that every cigarette smoked would shorten life expectancy by five minutes. But since then, non-smokers have obviously enjoyed a longer life span, so the harm of cigarettes to life span has increased relatively.
At present, about one-third of people in Britain smoke, and about120,000 people die of smoking-related diseases every year, two-thirds of which are cancer and heart disease. Researchers hope that this new study will encourage more people to make up their minds to quit smoking at the dawn of the new century.
The host of a smoking cessation action group said that this figure shows that if a person smokes 20 cigarettes a day, it means that he will lose one day every week he smokes; If this is not bad enough, he warned, smoking may cause people to die painfully or stay in bed more frequently.
Tobacco smoke contains at least three dangerous chemicals: tar, nicotine and carbon monoxide. Tar is a mixture of several substances, which will be concentrated into a viscous substance in the lungs. Nicotine is an addictive drug, which is absorbed by the lungs and mainly acts on the nervous system. Carbon monoxide reduce that ability of red blood cells to deliver oxygen to the whole body.
A person who smokes/kloc-0.5 to 20 cigarettes a day is four times more likely to develop lung cancer, oral cancer or laryngeal cancer and die than a non-smoker. The mortality rate of esophageal cancer is four times higher than that of non-smokers. The risk of dying from bladder cancer is twice as high; The risk of dying of heart disease is twice as high. Smoking is the main cause of chronic bronchitis and emphysema, and chronic lung disease itself will increase the risk of pneumonia and heart disease, and smoking will also increase the risk of hypertension.
Smoking is harmful to your health.
According to Jeffrey Smith, an American dermatologist, a survey of 58,726 smokers in this country found that smoking not only damages the heart and lungs and consumes vitamin C in the body, but also harms the skin.
1, wrinkles
Like exposure to sunlight, smoking can cause elastin and elastic fibers to thicken or break. In addition, smoking will also reduce the oxygen supply to the skin, affect the formation of collagen, the main component of the skin, and lead to dry skin. All these aggravate the appearance of wrinkles. For female smokers, it will also affect the estrogen cycle.
2. Skin cancer
Smoking can induce carcinosarcoma. After the appearance of melanoma, smokers are twice as likely to have melanoma necrosis as non-smokers.
3. Other cancers
The risk of lip cancer, oral cancer, * * cancer, * * cancer and vulvar cancer of smokers is much higher than that of non-smokers.
4. The wound heals slowly
After abdominal surgery or facial plastic surgery, the wound healing of female smokers is obviously slower than that of non-smokers. The failure rate of skin transplantation in smokers is also high.
5, psoriasis and skin diseases
The probability of smokers suffering from psoriasis may be 2-3 times higher than that of non-smokers. Some abscesses on the palms and feet are almost unique to smokers. This skin disease is difficult to cure, even if you quit smoking in the future, it will not disappear.
6, oral lesions
Tar in cigarettes and the heat of cigarettes will inflame salivary glands, thus forming abscesses or mucosal leukoplakia on the tongue and palate. Smokers are six times more likely to suffer from mucosal leukoplakia than nonsmokers. Although leukoplakia is benign, it may also induce cancer. Nicotine in tobacco is a highly toxic alkaloid.
A cigarette shortens life 1 1 min.
According to a new study, smoking can shorten people's life span 1 1 minute. If you smoke a pack of 20 cigarettes a day, it may reduce people's life expectancy by about 3 hours and 40 minutes. This estimate is based on people who started smoking at the age of 17 and died at an average age of 7 1 7. Suppose he smokes 15 cigarettes a day like the average British addict, he will consume 3 1 1688 cigarettes in his life. On average, smokers die six and a half years earlier than non-smokers.
A similar study decades ago concluded that every cigarette smoked would shorten life expectancy by five minutes. But since then, non-smokers have obviously enjoyed a longer life span, so the harm of cigarettes to life span has increased relatively.
At present, about one third of Britain ... >>
Question 4: What is the difference in life expectancy between smokers and non-smokers? According to statistics, smoking a cigarette reduces life expectancy by an average of 5 minutes, and long-term smoking can reduce life expectancy by 5-8 years. It is reported that the death rate of smokers is 1.7 times that of non-smokers. The death rate of people aged 35-65 who smoke more than 25 cigarettes a day is 2.5 times that of non-smokers.
Different components of smoke can cause many diseases. According to statistics, smoking kills 6.5438+0.7 million patients with coronary heart disease and 6.5438+0.3 million patients with cancer every year in the United States. Among patients with ischemic heart disease, the probability of cardiac arrest of smokers is four times that of non-smokers. The mortality rate of lung cancer in smokers is 10.8 times that of non-smokers. Smoking while eating is more likely to lead to swallowing and induce gastric cancer, especially cardiac cancer. The specific risk of gastric cancer among smokers every day is 30. 1%.
Question 5: How long can smokers live? Generally, sixty or seventy years old is not bad. If the lung injury is serious, it is a bit dangerous. You may get sick and die.
Question 6: What is the relationship between smoking and people's life span? There are too many people smoking lung cancer now. Let's smoke less for the sake of health. Smoking is not a good thing.
Question 7: Does smoking affect people's life span? Low tar cigarettes are still harmful.
Many smokers feel comfortable because they smoke cigarettes with low tar content, thinking that the harm can be ignored. A recent study in the United States shows that low-tar cigarettes are not helpful to protect health, so smokers should not make excuses for smoking. Michael, director of the Institute of Epidemiology of the American Cancer Society? Dr Stern compared and analyzed the relationship between the tar content of four kinds of cigarettes and the incidence of cancer. The subjects were 364,239 men and 576,535 women, and the follow-up survey lasted for 6 years. It was found that smokers who smoked cigarettes with low tar content had the same risk of lung cancer as smokers who smoked cigarettes with high tar content.
The investigation also found that smoking has a certain relationship with carcinogenesis, and different smoking methods can determine the contact degree between lung surface and carcinogens, thus promoting the induction of certain types of lung cancer. Research shows that as long as you smoke, the harm is the same.
Professor Dai, the experimental base of Shanghai Health Education Promotion and Cooperation Center of the World Health Organization, believes that this view of American experts is correct. Like cigarettes with filters, cigarettes with low tar content only reduce the proportion of some harmful substances such as nicotine, but can not reduce the harm to human body.
Cigarettes contain carcinogen 3,4-benzopyrene, which can only be activated by aromatic hydrocarbon hydroxylase in the body. The amount of this enzyme determines the strength of canceration, and the amount of this enzyme has a certain relationship with heredity. Therefore, people with family history should quit smoking as soon as possible, because smokers may develop lung cancer within 10 years after quitting smoking.
The harm of smoking to the body is related to genes.
A recent study in the American medical community found that how much harm smoking does to the body may be related to genes. If pregnant women lack genes to prevent tobacco damage, the situation of neonatal underweight is the most serious.
According to the report published by Boston University School of Medicine, there are two genes related to the chemical reaction caused by smoking, one of which can prevent the harm caused by smoking, and the other can strengthen the harm.
The investigation of 700 newborns in this study shows that if the newborn mother has the genes to strengthen the harm of smoking, but lacks the genes to prevent the harm, the newborn is the most seriously underweight, with an average reduction of 1360 grams and premature delivery of 5 weeks.
More than 300,000 babies in the United States are underweight every year, that is, they weigh less than five pounds and eight ounces (2,500 grams). Underweight is the main cause of neonatal death and neonatal defects, which may lead to various infant diseases. However, doctors are opposed to genetic screening for pregnant women, because the underweight newborn is a very complicated situation, and there are too many environmental risk factors and genetic factors leading to this result.
Attach a primary school student's opinion: as soon as I get home today. I saw it covered with smoke, which made me cough and feel chest tightness. At first glance, it turned out that dad was smoking again. In this ashtray, ah! There are eight cigarette butts, which pose a threat to me and my mother. So I investigated and analyzed the number of fathers smoking, hoping to attract the attention of every smoker and let us grow up in clean air. 1. survey statistics: according to the survey, the number of cigarettes smoked by father every day is as follows. 65438+ 10 month 1: eight cigarette butts. 65438+10.2: six cigarette butts. 65438+10.3: Four cigarette butts. 65438+1October 4th: Nine cigarette butts. 65438+10.5: Four cigarette butts. Second, the experimental process: put a sparrow in a cage, close the door and smoke. Two minutes later: the sparrow began to crow. Eight minutes later: Sparrows start coughing and jumping. Ten minutes later: the sparrow began to be restless, flying up and down in the dragon, hitting the cage with its head and trying to fly out. Three. Information inquiry: When people smoke, a lot of harmful substances will be released during the burning of cigarettes, which will damage people's liver and lungs and cause great harm to human health. Nicotine, a harmful component in cigarettes, will affect your lungs, make you unable to breathe normally, and also affect your liver, which will lead to cirrhosis and dry mouth. 4. My opinion: People who love smoking, please give up smoking for the health of you and others!
Question 8: How many smokers are there in China? At present, the number of smokers in China is roughly 350 million. China tobacco has maintained seven world firsts for many years: the tobacco planting area is the first; The purchase amount of tobacco leaves is the first; Cigarette production comes first; Cigarette consumption is the first; The number of smokers ranks first in the world; Tobacco profits and taxes first; The number of people who died of smoking-related diseases ranked first. Since 2000, about 1 10,000 people in China have died of smoking-related diseases every year, accounting for one fifth of the global deaths.
Last June, 5438+065438+ 10, a 9-year-old girl in Shandong was diagnosed with advanced lung cancer. When she found it, there was water in the right chest, a lump in the lung, and cancer cells in the lung, pleura and mediastinal lymph nodes metastasized, and the treatment was hopeless.
The incident caused a great shock in the domestic medical anti-cancer field. Yang Xiujun, director of the Radiology Department of Shanghai Eighth People's Hospital and member of the professional committee of minimally invasive tumor treatment of China Anti-Cancer Association, mentioned this case to China Business News. He said that it was later verified that the child's father had been drinking for many years and could smoke two packs of cigarettes every day, and he never avoided it in front of the children. I didn't give up smoking even though my wife was pregnant. Children get lung cancer because of passive smoking every day.
According to the latest data released by the Ministry of Health on May 29th, there are currently 350 million smokers and 540 million passive smokers in China, including children under 5 years old/kloc-0.80 billion, and the number of people who die from passive smoking has exceeded/kloc-0.80 billion every year.
May 3 1 this year is the 20th World No Tobacco Day with the theme of creating a smoke-free environment. However, smoke-free environment has been a tragedy in China for ten years. An internal research report shows that since 1997, European and American international cigarette giants began to enter the Asian market, especially China, because of the influence of domestic smoking ban policy. However, the pace of tobacco control in China lags far behind that in Europe and America.
Smoking and poverty
The harm of tobacco to health is self-evident, and the role of tobacco in death and disease has been well confirmed. However, the poverty aggravated by tobacco has not been paid enough attention. Limited family resources are consumed on cigarettes instead of food and other necessary expenses, such as education and nutrition. The expenditure of poor families on cigarettes (accounting for 4%~5% of their total disposable income) has a very high opportunity cost, which wastes valuable resources that should meet basic needs such as food.
As early as 1995, the eighth World No Tobacco Day, tobacco control and poverty reduction have been put forward as the theme. According to the information provided by patriotic health campaign committee at that time, China ranked first in the world in tobacco production, sales and the number of smokers, and the economic income generated by tobacco accounted for a large proportion of the national fiscal revenue.
In May 2003, the World Health Organization 192 member countries finally adopted the Framework Convention on Tobacco (hereinafter referred to as the Convention), and China was one of them. Member States are committed to addressing the public health challenges posed by tobacco, and are determined to address key issues such as tobacco prices and taxes, tobacco and poverty, cross-border smuggling, tobacco advertising and promotion, and the right to clean indoor air.
The report of the World Health Organization shows that the phenomenon that tobacco cultivation and consumption increase poverty has been ignored. Although the consumption of tobacco in many high-income countries has been declining in recent years, it is rising sharply in low-and middle-income countries.
75% of global smokers are in developing countries, and about 60% of global cigarette consumption (5.7 trillion cigarettes) is sucked away every year. This in itself confirms the necessity of comprehensive tobacco control. However, it must be noted that the relationship between tobacco use and its related disease burden is inclined to some extent. In other words, the poor are more inclined to use tobacco than the rich, and there are similar situations in education and socio-economic status.
Professor Yang Gonghuan, deputy director of China Center for Disease Control and Prevention and vice president of China Tobacco Control Association, once said in the media that many people failed to feel the harm of tobacco to health because the role of tobacco did not happen immediately. At present, the average life expectancy of smokers in China is 4.6 years less than that of the general population, and each person works two years less on average, creating much less labor value. However, according to the current smoking pattern, the number of smokers will increase to 436,543.8+billion by 2030, and nearly 2 million people will die from diseases caused by smoking every year from 2025.
Yang Gonghuan said that the use of tobacco has led to an increase in medical expenses, while the current medical expenses have increased >>
Question 9: Will smoking reduce life expectancy? According to a health study, the average remaining life of male smokers at the age of 40 is 3.5 years shorter than that of non-smoking men. The more you smoke, the shorter your life expectancy. Men who smoke at least two packs of cigarettes a day live 0.9 years less than men who smoke less than 20 packs. The mortality rate of smokers suffering from lung cancer is 20 times that of non-smokers. The risk of gastric ulcer and angina pectoris of smokers is 65438 02 times and 9 times that of non-smokers, respectively. "The impact of smoking on life expectancy is more obvious in men, but this trend also exists in women."
