The cigarette smoking invented by primitive man spread quickly around the world, and there are many smokers in 193 countries around the world. Relevant data show that there are many cigarette factories in every country that produce cigarettes. Our ancestors invented smoking for survival, in order to play its role in retaining fire, and popularized smoking, in the primitive society at that time, it was impossible to realize the harm of smoking to the human body. In 1924, with the development of science and technology, people gradually realized that smoking is harmful to health.

According to relevant reports, in 1924, the American "Reader's Digest" published an article for the first time, reminding people to pay attention to the harmful effects of smoking. In 1966, a new logo began to be printed on cigarette packages in the United States: Beware! Smoking is harmful to health. However, people who smoke do not think so, and they always feel that their body is healthy, and they continue to smoke.

Although most countries in the world are promoting smoking cessation, and some countries have even passed laws to ban smoking, the effect is not good, and the number of smokers continues unabated. According to relevant statistics, there are about 1 billion to 1.3 billion smokers in the world, accounting for about 20% of the world's population and more than 30% of the adult population. With 10 trillion cigarettes sold annually and hundreds of billions of dollars sold, sales have doubled from 20 years ago and are growing at a rate of 2.5 percent per year. Except for a few developed countries that have effectively implemented smoking cessation campaigns and a slight decrease in the number of smokers, most countries are still increasing, especially in developing countries, and the range of smoking is also expanding, especially the number of female and adolescent smokers has increased significantly. There are currently about 250 million to 300 million people in our country who smoke, accounting for more than 20% of the country's population. There are also quite a few smokers in the United States, with nearly 100 million in previous years. In recent years, there has been a slight decrease due to the promotion of smoking cessation, but at least it is around 70 million. In other countries, the 12 countries of the European Community account for about 37% of smokers, with Denmark accounting for 46% and Belgium having the lowest at 32%. As the number of smokers has increased and cigarettes have sold well, the area under tobacco cultivation in the world has not decreased, and more than 100 countries and regions have obtained higher incomes from tobacco cultivation, such as Brazil, India, Uruguay and Zimbabwe. However, there are a few countries where the number of smokers is decreasing, with the UK reducing by about 27 per cent, the US by more than 20 per cent, and Singapore having the most effective cessation campaign and which is striving to become a non-smoking country.

According to relevant information, tobacco is extremely harmful to the human body, a person who smokes 15 to 20 cigarettes a day is susceptible to lung cancer, oral cancer or laryngeal cancer, and the chance of death is 14 times greater than that of non-smokers; They are 4 times more likely to die from esophageal cancer than non-smokers; The chance of dying from bladder cancer is twice as great; The chances of dying from heart disease are also twice as great. Cigarette smoking is a major cause of chronic bronchitis and emphysema, while chronic lung disease itself increases the risk of pneumonia and heart disease, and smoking also increases the risk of high blood pressure. The smoke from smoke, especially the tar it contains, is a carcinogen – that is, it can cause cancer in the tissues it touches, so it can develop cancer anywhere in the smoker's airway, including the mouth and throat. Nicotine causes the heart to beat faster and blood pressure higher, and tobacco smoke, possibly due to carbon monoxide, seems to promote atherogenesis, which is a cause of many heart diseases, and people who smoke a lot of cigarettes have a much greater chance of dying from a heart attack than non-smokers.

It has been shown that pregnant women who smoke 15 to 20 cigarettes a day are twice as likely to have a miscarriage as non-smokers, and are more likely to give birth to premature or frail babies, and that the mortality rate of babies born to women who smoke is about 30% higher than that of babies born to non-smokers. 1.3 billion people in the world smoke, 4.9 million people die every year due to smoking, Xinhuanet 2009-08-26 report: The World Lung Foundation and the American Cancer Society cancer experts released a research report on the 25th, the world will die of 6 million people next year from smoking-caused cancer, heart disease and other diseases. There are currently 350 million people in China who smoke, and the number of people who die from smoking every day is as high as 13,400, ranking first in the world.

Since the 50s of the 20th century, a large number of epidemiological studies have confirmed that smoking is the leading risk factor for lung cancer. In order to arouse the attention of the international community to the harm of tobacco to human health, the World Health Organization proposed in November 1987 that April 7 of each year be designated as "World No Tobacco Day", which was implemented in 1988. Since 1989, World No Tobacco Day has been celebrated on 31 May every year. We also observe this day as a No Tobacco Day in our country.

Due to the importance attached by our country and the extensive and serious publicity and education, the Chinese people have begun to realize the harm of smoking to the human body. smoke-free factories; smoke-free units; Smoke-free buses, etc., some units have set up smoking rooms in order not to endanger others from the smoke from smoking; Many old smokers have quit smoking, and some are quitting. The work of quitting smoking has made certain achievements, which is the mainstream of smoking cessation in our country, and it should be affirmed and praised.

However, there are still a lot of negative perceptions among Chinese people, and many smokers are reluctant to quit smoking, and some say: "I can go a day without eating, but I can't go a day without smoking." Others said: "The life span of a person is determined by God, and it has nothing to do with smoking." I know a friend who is very addicted to cigarettes and has to smoke two packs of cigarettes a day, and everyone advised him to quit smoking, he said: "Don't listen to those propaganda, I think smoking is not only harmless to the human body, but smoking is bactericidal and conducive to the health of the body." As a result, he contracted lung cancer and was admitted to the hospital, where he died at the age of 45 after several months of ineffective treatment. There is also a company leader, smoking a particularly big addiction, smoking two packs of cigarettes a day, when people advised him to quit smoking, he did not listen to the advice at all, and said with a smile: "Smokers live a long life, because smoke is anti-virus, if you don't believe it, in the hot days of June, you can buy two catties of fresh pork, take a pound and put it on the table and leave it alone, put another pound of meat on the farmer's firewood stove and hang it, smoke it with smoke, three days later, a pound of fresh meat on the table has been stinky and spoiled, and put it on the wood stove with smoke smoked that pound of fresh meat, It has been smoked into bacon, not only does it not stink, but it is still very fragrant when cooked, you think about it, this cigarette should be sterilized and detoxified. He used this method of smoking bacon to resist the good Samaritans who persuaded him. As a result, when he was 42 years old, he was hospitalized for lung cancer treatment, and when his friends went to visit him in the hospital, he said to his friends with tears in his eyes: "Friends, I didn't take quitting smoking as a thing before, but I hurt myself, you must quit smoking...... He was hospitalized for a few months, because he was in the advanced stage of lung cancer, and the treatment was ineffective.

There is a scientific basis for the health effects of smoking, and there are many cases that prove it beyond doubt. Smokers: For the sake of your health and the happiness of your family, quit smoking.
