DISADVANTAGES OF SMOKING
It is one of the most harmful habits that seriously damage human health.
The homeland of tobacco is South America, the Spaniards brought it to Europe in the 16th century. At first it was customary to snuff or chew tobacco. Gradually, it became smokeable, because when tobacco is smoked, the main substance in it - nicotine - has a stronger effect. Nicotine has a temporary stimulating effect on the central and peripheral nervous system (see Peripheral nervous system, Central nervous system), increases arterial blood pressure, narrows small blood vessels; accelerates breathing, strengthens the juice of the digestive system. Along with nicotine, combustion products in tobacco smoke also poison the body.

Therefore, it is harmful for non-smokers to be in a smoky room. Inhalation of smoke containing combustion products reduces oxygen in the arterial blood (hemoglobin, which carries oxygen, loses its ability to bind oxygen). It affects the bronchial mucosa and causes chronic bronchitis and pulmonary emphysema. Smokers tend to cough.
T.ch. often causes dangerous tumors in the oral cavity, throat, bronchi and lungs. Chronic long-term smoking causes a person to age quickly. Poor supply of tissues with oxygen, narrowing of small vessels changes the appearance of smokers (the whites of the eyes and skin become yellowish, paleness appears). Changes in the mucous membrane of the airways affect the sound (the voice becomes muffled, the timbre decreases, the lungs crackle). Nicotine has a more negative effect on young people and the elderly, because their nervous system is more sensitive to the effects of nicotine.

Nicotine is especially harmful for pregnant women. Because the child is born very weak and light. Nicotine is also very dangerous for lactating women, because it causes many diseases and deaths of children in the first years of life. Nicotine aggravates atherosclerosis, hypertension, gastritis, gastroenterocolitis, myocardiodystrophy and some endocrine diseases. Ulcer disease, thrombophlebitis, obliterating endarteritis without giving up pus. It is difficult to recover from diseases such as Raynaud's disease, angina pectoris, myocardial infarction.

T.ch. because of how harmful it is, many countries are taking anti-smoking measures recently, the sale of tobacco products, smoking in public places and transport is prohibited, etc. The statement of many smokers that a person can get sick after quitting is certainly unfounded, because he who abstains from poison is never harmed. For a long time T.ch. It is certainly difficult for a person who is used to smoking to quit suddenly. Therefore, after quitting smoking, it must be under the supervision of a doctor. It is true that people who quit smoking sometimes gain weight. Indeed, in the first weeks, a person's weight increases, but this is a general decrease. But later the metabolism is normalized. Therefore, during this period, it is recommended to eat foods made from milk and plant products. It is necessary to regularly engage in physical work. Smokers say that smoking improves concentration and mental performance. But it should be remembered that the work of the nervous system is temporarily improved under the influence of nicotine, but the energy capacity of the brain is damaged. As a result, a person smokes continuously while engaged in mental work; as a result of heavy smoking, the body was strongly poisoned by tobacco; a person's head hurts, his color fades, his mouth becomes dry and he has a bad taste, heart palpitations begin. What was supposed to improve brain function now turns into a debilitating harm. It is necessary to regularly engage in physical work. Smokers say that smoking improves concentration and mental performance. But it should be remembered that the work of the nervous system is temporarily improved under the influence of nicotine, but the energy capacity of the brain is damaged. As a result, a person smokes continuously while engaged in mental work; as a result of heavy smoking, the body was strongly poisoned by tobacco; a person's head hurts, his color fades, his mouth becomes dry and he has a bad taste, heart palpitations begin. What was supposed to improve brain function now turns into a debilitating harm. It is necessary to regularly engage in physical work. Smokers say that smoking improves concentration and mental performance. But it should be remembered that the work of the nervous system is temporarily improved under the influence of nicotine, but the energy capacity of the brain is damaged. As a result, a person smokes continuously while engaged in mental work; as a result of heavy smoking, the body was strongly poisoned by tobacco; a person's head hurts, his color fades, his mouth becomes dry and he has a bad taste, heart palpitations begin. What was supposed to improve brain function now turns into a debilitating harm. under the influence of nicotine, the work of the nervous system temporarily improves, but the energy capacity of the brain is damaged. As a result, a person smokes continuously while engaged in mental work; as a result of heavy smoking, the body was strongly poisoned by tobacco; a person's head hurts, his color fades, his mouth becomes dry and he has a bad taste, heart palpitations begin. What was supposed to improve brain function now turns into a debilitating harm. under the influence of nicotine, the work of the nervous system temporarily improves, but the energy capacity of the brain is damaged. As a result, a person smokes continuously while engaged in mental work; as a result of heavy smoking, the body was strongly poisoned by tobacco; a person's head hurts, his color fades, his mouth becomes dry and he has a bad taste, heart palpitations begin. What was supposed to improve brain function now turns into a debilitating harm.
T.ch. It has been proven in science that it poisons heredity and causes the birth of stunted and defective children. It is possible to quit smoking no matter how hard a person is. For this, he must have a strong will and a firm decision to quit smoking. After 3-5 days after giving up this habit, a person may feel some discomfort, become angry at something, disturb sleep, lose appetite temporarily, sometimes have a headache. A person who wants to quit or who has quit T.ch. should see a narcologist in any case. Udori helps using drugs and psychotherapy methods. When quitting smoking, you should not treat yourself with drugs, because almost all such drugs are drugs that have a strong effect on the body and can make the heart fail.
Smoking is one of the harmful habits. According to scientific research, tobacco smoke contains more than 3000 different toxic chemicals. Nicotine, ammonia, carbon dioxide, benzene, polonium, cadmium have a strong toxic effect on the human body. For example, nicotine narrows blood vessels and increases blood pressure, carbon dioxide combines with hemoglobin in the blood and disrupts the normal supply of oxygen to the brain, heart and other important organs, causing headaches and heartburn.
Tobacco smoke contains more than 50 cancer-causing chemicals. That is why cancer is 20 times more common among smokers than among non-smokers. 95% of lung cancer patients are smokers. Chemicals contained in tobacco smoke are the cause of many diseases in addition to cancer. Including hypertension, ischemic heart and myocardial infarction diseases, chronic bronchitis and pulmonary emphysema, chronic gastritis, stomach ulcer disease, allergies and other diseases. Myocardial infarction, one of the most dangerous diseases, occurs 12 times more often in smokers than in non-smokers. According to American scientists, the average age of those who died from heart disease was 67 in non-smokers. in smokers it was 47 years. It can be seen that smoking shortens a person's life by 20 years.
According to the information of the International Health Organization, 2.5 million young people die from diseases caused by smoking every year.
It has been scientifically proven that radioactive polonium contained in tobacco smoke can damage the reproductive organs of a chicken and cause hereditary diseases in its children. Such children have been found to have particularly weak intellectual development.
In addition to poisoning the smoker's own body, he also causes great harm to the health of those around him. Toxic substances contained in the smoke released from the smoking cigarette and the respiratory organs of the smoker poison the ambient air and enter the respiratory organs of the surrounding people with the air.
According to observations, the wives of smokers live four years less on average than the wives of non-smokers. They are especially prone to cancer, hypertension, heart and lung diseases. Toxic substances in cigarette smoke cause great harm to the organism of pregnant women. For example, as a result of these substances poisoning the internal secretion glands of a woman, the secretion of hormones necessary for the normal growth of the fetus decreases. In addition, the toxic substances that enter the respiratory organs of a pregnant woman pass into her blood, and from there through the uterus to the blood of the child. and poisons his brain, heart, and liver. Consequently, such children are born sick. Since their body is weak at birth, they are more susceptible to various diseases.
Due to the fact that children from smokers' families constantly breathe in poisoned air, they are susceptible to allergic diseases such as inflammation of the respiratory organs, especially asthmatic bronchitis, bronchial asthma. Since the body of these children is constantly poisoned by chemicals in cigarette smoke, any disease they have is severe and lasts a long time, and often recurs.
According to doctors' observations, allergic diseases of respiratory organs such as chronic asthmatic bronchitis and bronchial asthma of children living in smoking families do not occur when their father goes on a trip or vacation for a long time, that is, children feel better. As soon as their father returned home, it was known that their illness started within 2-3 days.
Toxic substances contained in cigarette smoke reduce the breast milk of a nursing mother. As a result, there is a need to feed the child with other foods. That is why most of the young children in families of smokers are forced to be fed artificially due to lack of mother's milk. Elderly smokers are harmful "examples" to young people, especially teenagers. Because children and teenagers mostly follow the example of adults in their daily lives. They quickly join the ranks of adults and in order to become independent, they adopt and repeat the behavior and habits of adults. That's why more than 60 percent of teenagers who hold a cigarette in their hands are from families of smokers.
The economic damage of smoking is also great. Most of the smokers are often sick, so they have many days off work. They spend a lot of time smoking during the working day. Medicines are used to treat their illness. Medical staff are paid for their treatment. All this will harm the state economy to a certain extent.
In addition, a smoker harms the economy of his family. If he smokes a pack of cigarettes every day, he spends 2000-5000 soums or more in a year, depending on the type of cigarettes. Due to the increasing harmful effects of smoking on the health of smokers, the health of their family members, the production process, the education of young people, and the economy of the state and family, in the following years, all countries of the world will fight against this social disease. the fight is intensifying.
For example, in 2000, the US President's Council on Cancer adopted a public appeal to reduce smoking, which is one of the main causes of lung cancer. It is introduced that the salary is much higher compared to those who smoke.
In Belgium, people who smoke in production and public places will be fined 300 dollars, French scientists are strongly putting before the government the issues of expanding the view against smoking in the coming years, especially increasing the attention to educational outreach among schoolchildren.
In our country, measures against the disease of smoking are increasing day by day. In particular, efforts to explain the harmful effects of smoking to children and teenagers are being carried out on a large scale and are yielding positive results.

HARMS OF SMOKING ON THE HUMAN BODY
Even children know that one drop of nicotine can kill a horse. However, this argument does not make a special impression on smokers: they fool themselves with the statement that it is impossible to smoke so many cigarettes at the same time. However, the harm of tobacco smoke is not related to nicotine itself, it only causes addiction, the destructive effects of smoking are also expressed by other factors.
