What are the benefits of smoking? Tell me! ! ~

Smoking is very harmful to people's health, as follows: 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. The smoke of mouth and throat smoke (especially the tar contained in it) is a carcinogen-that is, it can cause cancer in the tissues it contacts, so any part of the smoker's respiratory tract (including mouth and throat) may cause cancer. Nicotine in the heart and arteries can make the heart beat faster and blood pressure rise. Tobacco smoke may be due to carbon monoxide, which seems to promote the accumulation of atherosclerosis. This condition is one of the causes of many heart diseases. Heavy smokers are much more likely to die of a heart attack than non-smokers. Toxic substances in cigarette smoke There are many different substances in the smoke of cigarettes, cigars and pipes. There are three most harmful substances, namely tar, nicotine and carbon monoxide, which are responsible for the premature death of many smokers. Is smoking really that harmful? I don't believe it. If we only compare the morbidity and mortality, how much higher smokers are than non-smokers, we can draw such a conclusion. That's a logical mistake. It can't be proved that these diseases are directly caused by smoking, let alone that smoking directly led to the death of some people. This is like randomly dividing people into two kinds, those who eat and those who don't; People who drink water, people who don't drink water; Married people and unmarried people. Then their morbidity and mortality must be different. But we can't say what disease we will get if we eat it, how harmful it is, how much higher the death rate of people who drink water than those who don't drink water, how many kinds of harmful gases, substances and elements are contained in the air, and we must not eat them, and so on. Such an inference can only scare non-smokers and has no effect on smokers, because this conclusion is groundless, specious and unconvincing. If stepping on nails is harmful, it is easy to prove. If you step on it with your feet, it hurts like hell, so you don't need much publicity, and people won't step on nails with their feet and hit the train with their heads. In my opinion, the harm of smoking should not be blindly concluded, let alone blindly concluded, which will only make the problem endless. It can neither convince smokers nor protect non-smokers. If you compare the incidence and mortality of any disease, then the incidence and mortality of smokers in many diseases are zero, such as SARS, which is known to all. But this does not prove that this is a great achievement of smoking. Because there is no direct connection. Some people say that Lin Biao did not smoke or drink and lived less than 60 years old; Zhou Enlai, who drank or didn't smoke, lived for more than 70 years. Mao Zedong, who smoked and didn't drink, lived in his 80 s; Deng Xiaoping smoked and drank, and lived for more than 90 years. What can this prove? Can you prove the great benefits of smoking? Obviously, you can't. Therefore, you can't convince people that smoking is harmful to health. So is smoking harmful after all? Why do so many people still want to smoke? I think smoking must be harmful, just as drinking water can be harmful. Some people die just because of a sip of water. As advertised, tobacco contains more than 4,000 chemical elements, of which at least 3,000 are harmful to human body. So that is to say, there are more than 1000 kinds that are good for health. Harmful elements, that is, they may damage some cells or functions of the body, but even these harmful elements are beneficial to the human body. That is, they not only harm people, but also destroy people's enemies and kill many germs and bacteria. Therefore, smokers suffer from far fewer diseases than non-smokers. In addition, there are more than 1000 elements in the smoke that are harmless and beneficial to human body. For non-smokers, it is a trace element that can never be absorbed, and it gives smokers many unproven benefits. Then you will find that by your side, smokers are always strong, while non-smokers are old, weak and sick. Of course, this view is only the author's own view. This is not the reason why you should smoke or give up smoking. What's more, I don't want you to be confused and overwhelmed by the words "both executioner and philanthropist" with a cigarette case that "smoking is harmful to health".
