Does smoking really give people a feeling of walking on clouds? What are the advantages and disadvantages of smoking in real life?

Disadvantages of smoking: Smoking in the brain can lead to various brain diseases, reduce oxygen and blood circulation in the brain, lead to cerebral vascular bleeding and occlusion, and lead to paralysis, mental decline and stroke. The cause of stroke is that smoking leads to cerebral vasospasm, which makes blood coagulation easier. Smokers are twice as likely to have a stroke as nonsmokers. Laryngeal smoking can cause laryngeal cancer. Laryngeal cancer patients are mostly male. Smoking can cause fat accumulation and vascular occlusion on the heart and blood vessels, making smokers prone to coronary heart disease. The death rate of heart disease caused by smoking accounts for 25% of the total. The prevalence of smokers over 50 has doubled. The prevalence rate of smokers under 50 years old increased 9 times, reaching 14 times. Smoking will constrict blood vessels, slow down the circulation of blood and oxygen, and eventually lead to thickening of blood vessel walls, leading to coronary heart disease and stroke. Smoking will completely block the blood circulation of hands and feet, leading to amputation. Smoking in the lungs can cause lung cancer. 90% of the total mortality rate is caused by smoking. The prevalence rate of a person who smokes ten cigarettes a day is ten times that of a non-smoker. Damaged cells can't return to normal. The initial symptoms will not be found until the cancer cells spread to blood vessels and other organs. Smoking can also cause emphysema, and toxic substances accumulated in the bronchi of the lungs will hinder the normal exhalation of the air inhaled by the human body, make lung cells expand or rupture, and cause patients to have difficulty breathing. For people with gastrointestinal diseases, smoking is enough to make them worse. People with gastric ulcer or duodenal ulcer will slow down the healing of ulcer and even become chronic diseases. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, make the gastrointestinal tract often tense, and lead to the loss of appetite of smokers. In addition, nicotine can also contract gastrointestinal mucosal blood vessels and reduce appetite. Bone smokers have a longer fracture recovery period than non-smokers. It may be that nicotine and carbon monoxide contained in cigarettes slow down the process of bone regeneration. Nicotine constricts blood vessels and reduces blood flow to new bones. The carbon monoxide inhaled during smoking also reduces the speed at which oxygen enters the body. Smoking can lead to osteitis and back pain. Smoking more than ten cigarettes a day will double the prevalence of periostitis. Most people with severe back pain are addicted to smoking, because smoking will reduce the blood flow of the articular disc and the articular disc will degenerate early. Smoking can lead to arthritis. Smoking a pack of cigarettes a day will increase the prevalence rate by 50%. Female smokers are more likely to suffer from fractures and arthropathy after menopause. Smoking will lead to faster bone loss. Women smoke a pack of cigarettes every day from adolescence to menopause, and their bones are 5% to 10% less than those of non-smokers. When smokers enter menopause, the bone loss rate is faster. Smoking can interfere with estrogen, which is an important hormone in bone development. Bronchial smoking is the main cause of chronic obstructive tracheal disease. Because smoking can cause the cilia of bronchial epithelial cells to become shorter and irregular, cause dyskinesia, reduce local resistance and be susceptible to infection. Smoking in the liver will increase the burden on the liver. Regular smoking will affect the lipid metabolism of the liver, increase blood lipid, decrease benign cholesterol and increase malignant cholesterol. This has caused the burden of detoxification function of the liver to increase. Intestinal smoking can lead to colon cancer. The risk of this kind of cancer is directly proportional to the amount of smoking. Research shows that although quitting smoking can reduce the risk of heart disease, lung cancer and other diseases, the risk of colon cancer is still high. Eye smoking can lead to cataracts and affect vision. Research shows that there are twice as many cataract patients who smoke more than one pack a day as those who never smoke. Secondhand smoke Secondhand smoke is a kind of mixed smoke that is burned or exhaled by cigarettes, pipes or cigars when smokers smoke. Secondhand smoke is the most common pollutant in many smoking places. Smoke emitted during smoking can release more than 4,000 kinds of gases and particles, most of which are very strong irritants, and at least 40 of them can cause cancer in humans or animals. After smokers quit smoking, these particles can still stay in the air for several hours, can be inhaled by other non-smokers, and may be mixed with the decay products of radon gas, causing great harm to human health. When smoking harms smokers' own health, second-hand smoke will also affect non-smokers. In addition to irritating eyes, nose and throat, it will significantly increase the risk of lung cancer and heart disease in non-smokers. If children live with some smokers, their respiratory system will be more susceptible to infection. Other effects include increasing cough, asthma, excessive phlegm, impairing lung function and slowing lung development. The benefits of smoking: Few people will admit the benefits of smoking. However, from the viewpoint of materialist dialectics, everything has two sides. If there is a bad side, there will be a good side. This of course includes smoking. Existence is reasonable, so smoking should have certain benefits, and smoking has reasons to smoke. As a smoker, I have several reasons to smoke. First of all, smoking is a pastime. When you are bored or depressed, smoking a cigarette is a good pastime and relaxation. Secondhand smoke caused by smoking will hurt others, but the biggest harm caused by smoking is the smoker himself. If you avoid others, enjoy smoking alone or use smoking to relieve depression, smoking should not be a bad thing. If we must say that smoking affects health, we can also cite many people who are heavy smokers but can live long. The most famous is the former British Prime Minister Winston Churchill, who was described as a "giant cigar" and lived to be in his nineties. Secondly, smoking is a way of communication. When two strangers need to contact and communicate for some reason, it is inevitable that they will be a little stiff and have nothing in common when they meet for the first time, so the atmosphere will be a little awkward. But if two people are smokers, there is no need to search for words, just take out a cigarette and respect each other, and then we can chat while smoking. When thinking about the topic, talk with a cigarette in your hand. I smoked two cigarettes when I didn't expect the topic, so as not to look around and find the topic. If you meet people with high status, give them a good cigarette, which is not only a tribute, but also a small bribe. Light a cigarette, you can get closer and appear more intimate, and it will definitely help you get things done. It's better than standing there at a loss. If people in high positions want to ease relations, it is also a simple and effective way to give a cigarette to their subordinates. Thirdly, smoking can satisfy the psychology of indulgence. Everyone has factors in his bones that he is unwilling to follow the rules. Too dull, sometimes it makes people feel inexplicably upset. Therefore, some people choose to drink, some people choose to smoke, and some people choose some actions that can stimulate the senses, such as gambling and whoring, to break some routines while seeking sensory stimulation and gain a sense of indulgence. Relatively speaking, smoking can be regarded as a peaceful, cheap and less harmful indulgence. Finally, smoking is a consumer behavior that contributes to society. Smoking has a long history. Nowadays, smokers have developed into a huge group. Buying cigarettes has become a consumption that cannot be ignored, and making cigarettes has also become a big industry. Smokers support a huge manufacturing, consumption and tax industry. If there were no smokers, there would be more unemployed people in society and the government would lose a lot of financial revenue. Also, smoking can increase men's temperament. The attractive posture of men is usually considered as a sign of stability and maturity. Although mainstream public opinion never regards smoking as a good expression of men's temperament, the aesthetic standards or habits formed by people over the years have fixed the image of smoking men in the hearts of countless people. Mao Zedong and Deng Xiaoping, great men of their time, often smoke to keep their mood stable, and most writers seek inspiration by smoking. On the contrary, if the cigarette in a man's mouth is replaced by something else, the effect will not be so ideal. For example, in some movies, a man with a toothpick is too casual and even disgusting. In a Japanese movie, the protagonist detective likes to put a toothbrush in his pocket and put it in his mouth twice whenever he has time. Only when he was about to die after being shot, he was still struggling to put his toothbrush in his mouth. I always feel a little puzzled. I think it is a mistake and has nothing to do with temperament. We must admit that smoking is harmful. But we must also admit that smoking is not necessarily useless. These are the pros and cons of smoking. I don't know your attitude towards smoking, but I suggest smokers give up smoking for their own health and that of others.
