As the saying goes: “a cigarette after dinner, more than the living gods”, “morning tea and evening wine after dinner smoke”, smokers are always looking for various excuses for their “swallowing fog”. A few teenagers out of curiosity, or by the influence of people around smoking, often in the “suck and play” between, learned to smoke, and over time will develop a hobby. There is a famous cartoon, painted by the confession of the cigarette: “See? I’m burning my life!” At the same time, someone else wryly said, “When you light a cigarette, you invite cancer into your life.” In fact, smoking is harmful to the body, but not beneficial. And you, whether you also see the cigarette case on the line of text it – smoking is harmful to health. 1, the history of cigarettes The world’s earliest record of real tobacco appeared only after the discovery of the American continent by Christopher Columbus, on October 12, 1492, Columbus led an expedition to land on the island of San Salvador, among the native inhabitants found the scene of “smoking”, he wrote in the logbook. “Many men and women hold burning coals in their hands, so as to give themselves an aroma”. In fact, this “charcoal” is the tobacco rolled together. Tobacco, in the botanical classification belongs to the genus Tobacco, tobacco from the Americas to Europe is in 1558, when sailors sailing to bring the seeds of tobacco back to Portugal. In 1612, tobacco began to be planted on a large scale, and soon, the smoking habit spread throughout the European continent. According to historical documents, tobacco was introduced to China from the Philippines, Vietnam and Korea in the 16th century, and was soon accepted by the people. It is also said that around the beginning of the 17th century, the Dutch introduced North American Indian pipes with tobacco leaves into China through Taiwan, and China began to have a population of smokers. Ming Dynasty scholar Fang Yizhi “physical knowledge” in a book for the first time in the modern sense of the word “tobacco”. 2, the hazards of smoking Chinese medicine, as early as the middle of the 17th century, there are “long serving lung coke, non-affected diaphragm, that is, vomiting red, or yellow water and meteoric, suppressed and sick, the medicine does not work” of the disease records. In 1924, the American Reader’s Digest published an article entitled “Is Tobacco Harmful to the Human Body?” This was the first published article on “Smoking and Health” and attracted widespread attention at the time. In addition to the direct pathogenic effects of smoking on the trachea, bronchus and lungs, various scientific studies and epidemiological surveys have confirmed that smoking also poses a serious risk to the heart, brain, stomach, blood vessels, reproductive organs and functions, which can cause you to suffer from chronic bronchitis, emphysema, coronary heart disease, myocardial infarction, obesity, ulcer disease, stillbirth, premature birth and malignant tumors, and the chances of these systemic diseases are much higher than those of non-smokers. . After the decomposition of cigarettes by combustion, there are more than 4000 kinds of harmful substances in this smoke, such as alkali, benzo(a)pyrene, amines, nitrile, alcohols, phenols, aldehydes, alkanes, olefins, polycyclic aromatic hydrocarbons, nitrogen oxides, heterocyclic compounds, carbonyl compounds, arsenic, uranium, radium, radon, lead, polonium and other heavy metals and radioactive elements, organic pesticides, cyanide, narcotics, stimulants, etc. The most harmful ones are Carbon monoxide, nicotine and tar three substances, including nicotine, as long as the intake of 50 mg can make adults dead. 3, smoking and tumors In 1938, Johns Hopkins University, a professor of biology, the study was conducted. A professor of biology at Johns Hopkins University surveyed 6,813 people and found that 66% of non-smokers lived past the age of 60, while only 46% of smokers lived past the age of 60. This question and the small-scale survey showed that people had begun to worry about the growing group of “addicts,” but the lack of authoritative clinical evidence made the dangers of smoking far less important. In 1947, the British Medical Research Council found that the death rate from lung cancer in the British population was 15 times higher than it had been 25 years earlier. This phenomenon caused widespread concern in the medical community. There was widespread debate, with people pointing their criticism at the increasing air pollution, and of course, the claim that smoking caused lung cancer carried a lot of weight. As a result, the British Medical Research Council commissioned biometrician Bradford Hill to conduct a survey to prove that smoking causes lung cancer. Hill to conduct a survey to prove that smoking can cause lung cancer. At the time, 90 percent of adult men had a history of smoking. Into the pot directly from the lung cancer patients to distinguish between smokers and non-smokers, is undoubtedly a foolish approach, because Hill could hardly find non-smokers. Hill believes that smoking in the pot does lead to lung cancer, so the more people who smoke, the greater the chance of getting lung cancer. So he devised an ingenious scheme to find 649 cases of lung cancer patients and 649 other patients in similar situations from London hospitals. The smoking histories of the two groups were then registered one by one and a detailed statistical table was made. It was found that although the number of smokers in the two groups was approximately equal, 4 or 9% of the lung cancer patients smoked more than 50 cigarettes per day, while only 2% of the patients in the other group smoked the same amount of cigarettes per day. This controlled analysis initially revealed the fact that the more people smoked, the higher the chance of developing lung cancer, and in 1950, Hill published the results of this trial in the British Medical Journal. According to the latest figures provided by WHO, on average, one person dies from a smoking-related disease every 10 seconds worldwide. Each year, at least 3 million people die from smoking-related diseases, and 1 million of them die from lung cancer, accounting for 6 percent of all deaths worldwide each year. Smoking is harmful to the human body, both to active and passive smokers. Smokers directly inhale only about 10% of the smoke in the respiratory tract and lungs, while about 90% of the smoke is dispersed in the space around the smoker causing pollution of the ambient air quality and forcing non-smokers to smoke passively. Passive smoking is particularly harmful to infants, adolescents, and women. For children, passive smoking can cause respiratory diseases and affect normal growth and development; for pregnant women, passive smoking can cause stillbirths and miscarriages. For pregnant women, passive smoking can lead to stillbirths and miscarriages. There are more than 40 types of carcinogens produced by smoking that can directly cause cancer. In 1990, Pang Dexiang, who was studying for his master’s degree at Zhejiang College of Traditional Chinese Medicine, used his summer practice to publish an article in the Journal of Linyi Medical College, and conducted a national survey on smoking in three towns in Shandong Province, such as Zhaoxian and Luohe, with the assistance of the local epidemic prevention department, which surveyed a total population of more than 140,000 people into the group and found that smoking is closely related to common cancers such as lung cancer, esophageal cancer, stomach cancer and bladder cancer. There is also a close correlation with cardiovascular and cerebrovascular diseases. In November 2006, a 9-year-old girl in Shandong was found to have advanced lung cancer. When discovered, the girl had fluid in the right side of her chest and had distant metastases without any hope of cure. After expert investigation, it was found that the child’s father had smoked for years, even during his wife’s pregnancy, and that the child’s lung cancer was entirely due to long-term passive smoking. There have been many reports confirming the correlation between smoking and malignant tumors, the following is a set of eye-opening figures: ① Shortened life expectancy: a 25-year-old man who smokes 2 packs a day lives 8 or 3 years less than a non-smoker; ② Lung cancer: 10 times the incidence rate of non-smokers; ③ Throat cancer: 2 or 9-17 or 7 times higher than non-smokers; ④ Oral cancer: 3-10 times higher than non-smokers; ⑤ Bladder cancer: 3 or 10 times higher than non-smokers; ⑤ Bladder cancer: 3 or 10 times higher than non-smokers. times; ⑤ bladder cancer: 7-10 times greater than non-smokers; ⑥ esophageal cancer: 2-9 times greater risk for smokers; ⑦ pancreatic cancer: 2-5 times greater than non-smokers. As far as lung cancer is concerned, foreign scholars kubik reported that the incidence of heavy smokers between 40 and 60 years old is 50 times greater than that of nonsmokers; the incidence of lung cancer in American women has surpassed that of breast cancer in the 1980s; the same trend has been observed in British women with lung cancer; the incidence of lung cancer in Shanghai, China in 1984 was 63,94/100,000, which is 125,1% higher than that before 1965, and it has been increasing year by year. Therefore, almost all doctors have warned people: smoking is harmful to health, smoking in a sense is tantamount to chronic suicide. 4, quit smoking “smoking culture” in China can be described as deep-rooted. Smoking in China is a sign of maturity, smoking, handing out cigarettes, toasting is an important means of social interaction. Although the government has repeatedly advocated smoking cessation, but according to data show that there are still 300 million people who smoke, and the number of people suffering from passive smoking up to 500 million, 400 million! In other words, half of China is living in a smoky atmosphere. Since April 20, 2011, France has completely banned cigarette packaging trial brand logos and other marketing graphics, replaced by eye-catching and scary warning images and text, such as shockingly rotten lungs, rotten teeth, skeletons, etc.. China, too, has banned smoking completely in all indoor public places, public transportation and other outdoor public places since January 2011. However, the task of real tobacco control and cessation is still very daunting. At the same time, for individuals, quitting smoking is undoubtedly the first choice for a long and healthy life and freedom from cancer. Let’s work together to quit tobacco, so that the environment is clearer and people are healthier.
