Some people are skeptical about the harm of smoking. "Smoking can lead to cancer. Why do many people smoke without getting cancer? " This is because the incubation period of cancer is very long. The formation of cancer is a complicated process, which is related to many factors. It takes years to decades from the beginning of cancer cells to the development of cancer. Carcinogens destroy genes in cells, and a few cells may have pathogenic mutations, but they may not necessarily form cancer. After repeated contests of various cancer-promoting factors and anti-cancer factors, cancer cells and body immunity repeatedly confront each other, and cancer cells develop successfully, thus forming cancer. People who have a good living environment, a good mood, a proper diet, a regular life, insist on exercise and pay attention to hygiene have strong immune function, so it is possible to surround and annihilate cancer cells in the bud. Therefore, although some cells of long-term smokers have carcinogenic mutations, only some people eventually form cancer.
Stroke has something in common. Hypertension and atherosclerosis are the main causes, while hypertension and cerebral atherosclerosis caused by smoking cannot be realized in a short time. It takes at least 20 years to continue smoking before a series of diseases can be completed and symptoms of stroke can appear. Smoking causes serious diseases such as coronary heart disease, gastric ulcer and emphysema, and it takes a long time. Moreover, for various reasons, not all smokers can get these serious diseases before they die.
Considering this problem, we should not only look at the long-term harm of smoking, but also look at it. Don't take chances, we must fully realize the serious harm that smoking causes diseases and shortens life span. Moreover, it should not be ignored that smokers' health condition deteriorates, their physique declines, their memory declines, and their resistance to diseases declines, which is a common phenomenon.
Smoking not only harms oneself, but also harms others. Smokers smoke, and a large amount of smoke poison is discharged into the air, which seriously pollutes the environment. Smokers only inhale a small part of these harmful substances (25% nicotine, 29% carbon monoxide ...), and most of them are dispersed in the air and sucked away by people around them, which is the same as passive smokers smoking 5 ~ 10 cigarettes a day. According to the World Health Organization, the main cause of death from passive smoking is lung cancer or heart disease.
The husband smokes, and the wife suffers greatly. The incidence of lung cancer in women who live with their husbands who smoke for a long time is 2.4 times higher than that in women whose husbands don't smoke, and their average life expectancy is 4 years shorter. Women who marry smokers are 0.3-2 times more likely to die of heart disease.
The next generation is the biggest victim of passive smoking. Infants and young children are immature, have poor resistance, and are more likely to get sick if they smoke passively. The US government reports that secondhand smoke causes hundreds of thousands of children to suffer from serious respiratory diseases every year. Pregnant women smoke passively, and tobacco poison enters the placenta, uterus and fetus through blood, which makes the fetus anoxic, malnourished and stunted, which will increase the risk of miscarriage, premature birth or stillbirth. Newborns are light in weight, small in height and chest circumference, mentally retarded and prone to deformity. The weight of newborns who smoke secondhand smoke is 200 ~ 300g lower than that of those who don't smoke secondhand smoke, and the incidence of deformity is 1.8 ~ 3.8 times higher than that of those who don't smoke secondhand smoke.
Passive smoking is not limited to smokers' families. Anyone who has had contact with smokers for a certain period of time may be poisoned by passive smoking.
Smoking, for individuals, increases the economic burden and costs thousands of dollars extra every year. What's more, the money was exchanged for physical decline, illness and early death.
Smoking has caused great economic losses to society and the country. Since 1950s, the area planted with cigarettes in China has increased by 10 times, occupying more than10.5 million hectares of cultivated land, and reducing the output of grain, cotton and vegetables. In recent decades, the sales volume of cigarettes in China has increased by nearly 20 times. The number of smokers in China is increasing year by year, reaching nearly 400 million at present, and the annual tobacco consumption accounts for more than 1/4 of the world. People in western developed countries realize the harm of smoking, and more and more people give up smoking. The number of smokers has decreased year by year, but the output of cigarettes has not decreased. A large number of foreign cigarettes are dumped to developing countries to earn high profits.
China has become a big smoking country, which not only causes illness and death, but also brings us serious environmental pollution and huge economic losses. Treating various diseases caused by smoking and passive smoking costs huge medical expenses every year. Smoking leads to labor loss and premature death, resulting in huge economic losses. This problem alone far exceeds the profit and tax revenue that the country gets from cigarette production. As for the losses caused by smoking, such as disease pain, mental torture and family changes, it is even more incalculable.
Smoking leads to fires, car accidents, work-related injuries and other accidents, and the economic losses caused are also amazing. 15% of the fires are caused by smoking. The great forest fire in Daxing 'anling was caused by workers' illegal smoking. Smoking reduces people's endurance, speed, sensitivity and accuracy, not only affecting work efficiency, but also prone to accidents. According to foreign reports, the incidence of work-related injuries and accidents of smokers is 2.5 times that of non-smokers. To sum up, smoking seriously harms health, threatens life, pollutes the environment, brings troubles to family members, harms society, lowers the quality of the people and causes huge economic losses to the country. It is a serious social harm and a terrible "modern plague". Shouldn't it be sent away as soon as possible?
For the health of themselves and others, for the benefit of the country and society, friends who smoke should make up their minds and start quitting smoking immediately! Friends who don't smoke should be vigilant and never smoke the first cigarette.
