There are many hazards of smoking, the smoke produced by smoking has nearly 2000 kinds of harmful substances, such as nicotine, cyanohydrogen, carbon monoxide and some heavy metal elements, there are more than 40 kinds of carcinogens, such as benzidine and coal tar, etc.. Among them, the nicotine content is the most and the most toxic, and many sources show that the younger you start smoking, the greater the degree of victimization and the higher the mortality rate. If you smoke, you will notice that many problems will gradually appear. For example, your sense of taste and smell will weaken, you will get colds more often than before, your face will become more wrinkled, and you will get the annoying “smoker’s cough”, which is actually a symptom of chronic bronchitis. It also raises the chances of lung cancer, emphysema, high blood pressure, stroke and heart disease. It also causes your family to smoke secondhand, bringing them the same health risks. The earlier an individual starts smoking, the less likely that person is to quit. The act of trying quickly turns into liking and then indulging in nicotine, keeping the smoker hooked on the smoke. In addition to nicotine, the addictive substance, the other major harmful substances in tobacco are tar and carbon monoxide. Tar can collect in the lungs to form a sticky, brownish residue Tar consists mainly of a chemical called hydrocarbons, which are associated with the development of lung cancer and are a strong carcinogenic factor. Carbon monoxide is a toxic substance that replaces some of the oxygen that is normally carried throughout the body by red blood cells, leaving the body without enough oxygen. Switching to low-tar cigars is not helpful, as people routinely compensate for this change by inhaling longer or smoking more cigarettes. Smoking is the biggest cause of lung cancer, and domestic and international data show that the incidence of lung cancer in smokers is 15 to 30 times higher than in nonsmokers. Smoking is also a major cause of heart disease, and it contributes to heart disease by lowering high-density lipoprotein (HDL), the “good cholesterol” in the blood. In addition, smoking has a negative impact on the arteries that carry blood and nutrients to the heart. Smokers are twice as likely as nonsmokers to have heart disease. Men who smoke also suffer from impotence because the nicotine, carbon monoxide, and rutin in tar in tobacco cause atherosclerosis of the penile arteries, which significantly reduces the amount of blood available to the penis, making it impossible to get an erection. Smoking also has many other effects on the male genitourinary system, with smokers having lower normal sperm values than non-smokers. Also, sperm malformation rates have been found to correlate with the number of cigarettes smoked. Cigarette concentrates contain carcinogens, which are also present in the body fluids of smokers, and sperm receive such carcinogens and are susceptible to genetic damage. In addition, the relationship between smoking and kidney cancer is attracting more and more attention. Studies have shown that the causes of kidney cancer in men are more complex and have a lot to do with tobacco, socializing and stressful life, in addition to their own physiological factors. Some clinical studies show that the risk of kidney cancer in smokers is twice as high as that in nonsmokers, and the longer the smoking time and the greater the amount of smoking, the higher the risk, which is related to the long-term stimulation of the body by many toxic substances in tobacco. The harmful substances contained in tobacco, such as aromatic amines and acrolein, enter the blood circulation and are filtered by the kidneys and then excreted from the body through the bladder in urine. Therefore, smoking has been considered as a moderate risk factor for kidney cancer, with a higher increased risk than non-smokers, and there is also a significant relationship with the amount of smoking. The correlation between smoking and bladder cancer has long been a consensus in the industry, and studies have shown that bladder cancer caused by smoking accounts for 25% to 60% of all bladder cancers. The toxic and mutagenic effects caused by the action on the bladder acrolein in tobacco can cause diffuse bladder epithelial hyperplasia, and in one cigarette contains about 100 micrograms of acrolein. Children who passively smoke have an increased risk of developing bladder cancer when they grow up. Studies have also found that the risk of bladder cancer is four times greater in smokers than in nonsmokers, and that the risk of bladder cancer varies with the number of cigarettes smoked and the length of time smoked. Although smoking does not directly cause prostate disease, it has a close relationship with prostate disease because smoking can make the body’s immunity decline. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
