Why do some people know that smoking is harmful to the body?

Smokers are prone to stomach ulcers because the nicotine in cigarette smoke can disrupt the acid-base balance in the digestive tract. In short, smoking is very harmful to health. According to a report by the World Health Organization, at least 1 million people worldwide die prematurely each year due to smoking.

The report also provides some staggering figures: 90% of lung cancer patients, as well as 1 3 percent of patients with various cancers, are caused by smoking, 75% of patients with chronic bronchitis and 25% of patients with heart disease are due to smoking. Smoking is not only harmful to oneself, but also to others, forcing others to "smoke passively".

In fact, all kinds of diseases that can be caused by smoking can occur in passive smokers. Adolescents are growing up and developing, and they are more likely to absorb harmful and toxic substances than adults, and they are more deeply poisoned. Smoking can also affect the moral development of young people.

The issue of tobacco control has become a widespread concern in all countries. Smoking is seen as an uncivilized habit in people's minds. The more developed countries are, the more smoking restrictions are taken, and the number of people who smoke is gradually decreasing.

Many countries** have announced strict anti-smoking laws that prohibit smoking in public places. In 1979, China approved the Ministry of Health and other "Notice on Publicizing the Harmfulness of Smoking and Controlling Smoking", and many health experts also issued a strong appeal, especially proposing that the problem of smoking among teenagers should arouse the attention and concern of the whole society, believing that this is a major event related to improving the quality of the nation and creating a good social atmosphere. When you are smoking, do you realize that you are unknowingly inhaling the harmful substances in cigarettes.

There are more than 2,000 harmful substances in cigarettes, the most important harmful substances are cigarette tar and carbon monoxide, and the addictive substance is nicotine. The longer you smoke, the more you smoke, and the more harmful you are. Passive smoking is also harmful to your health.

Smoking can cause you to suffer from diseases such as lung cancer, coronary heart disease, tracheitis and emphysema. Studies have shown that the development of smoking habits is mainly manifested in three aspects: physiological, psychological and social.

Physiologically, it is the body's dependence on nicotine. Psychologically, it is to take smoking as a part of life, get used to the act of smoking, and like the taste of cigarettes. In society, cigarettes are regarded as a means of socializing, or cigarettes as a symbol of a certain identity.

Therefore, for smoking cessation to be successful, it is necessary to start with these three aspects. Judging by many people who quit smoking repeatedly, quitting smoking by willpower alone is not enough. Some people say that smoking addiction is hard to quit, and it is difficult to quit smoking, but this is not true.

Actually, it's not that hard to stop smoking. Set a time to quit smoking now and start tomorrow. Quitting smoking requires determination and perseverance, as well as self-confidence.

Say to your family, friends, and co-workers that you quit smoking. If you have a strong craving for smoking and feel unwell after quitting smoking, you can use smoking cessation medications to help. In order to avoid smoking again, please do not buy cigarettes and do not accept cigarettes from others.

The chemical composition of smoking products is extremely complex, containing toxic substances such as tar, nicotine, phenols, alcohols, etc., and some of them also have carcinogenic effects. 1. It is easy to cause respiratory diseases: the smoke produced during smoking mainly enters the human body through the respiratory tract, and the respiratory tract becomes the part that is most damaged by the harmful substances in tobacco.

Harmful substances will directly act on the mucous membranes of the respiratory system such as trachea and bronchi, inducing bronchitis, pharyngitis, emphysema and other diseases; 2. It is easy to cause cardiovascular diseases: nicotine in tobacco will promote vasoconstriction, cause coronary artery contraction of heart blood, thereby affecting the blood of myocardial tissue, and induce cardiovascular diseases such as coronary heart disease and hypertension; 3. Easy to cause cancer: cigarette tar is one of the most important carcinogens in cigarette smoke, cigarette tar contains polycyclic aromatic hydrocarbons and nitrosamines-based carcinogens and some phenolic carcinogens, studies have shown that tobacco contains at least 43 known carcinogens, and about 30% of cancer deaths are due to tobacco.

Smoking can easily induce lung cancer, oral cancer, laryngeal cancer, leukemia, cervical cancer, etc.; 4. Other hazards: Smoking can also affect eyesight, lead to menstrual disorders, roughness, digestive disorders, etc. Smoking during pregnancy may also cause fetal malformations, miscarriages, etc.

All in all, smoking is harmful and not beneficial, it is recommended not to smoke as much as possible, and if you are a person who is smoking, it is recommended to actively quit smoking, which is good for yourself and others.

Many people say they smoke because smoking makes people feel clear-headed, energetic, and probably right in a way. Because the nicotine in smoke reaches the brain with the blood, it can prompt the human body to quickly produce some stimulant chemicals, and the accelerated blood circulation injects a large amount of blood to the brain, and the brain cells obtain sufficient oxygen and oxygen materials, so that people can obtain a short-term sober mind and refreshing effect.

Many people see that some older people do not get sick and have a fluke mentality, and they agree with some "true lies", such as "there are many smokers, but most of them do not get lung cancer", "some people smoke nothing, but after quitting smoking, they get lung cancer", "some people do not smoke but still get lung cancer", and so on.

The most important reason is that the damage to the body caused by smoking is a long and gradual process, so most people do not take it seriously.

Smokers generally have three misunderstandings about quitting smoking: first, they think that the human body has adapted to the balance of smoking, and if they quit smoking, it will be harmful to the body; Second, it is believed that smoking a small amount of cigarettes is not harmful to the body; Third, it is believed that if there are few smokers and the space is not large, it will not be harmful to non-smokers; Fourth, nicotine has the effect of central nervous system stimulant and refreshing, and is the main substance that causes cigarette addiction. 5. Under the pressure of life and work, cigarettes are a psychological placebo.

The first is that smoking is addictive, and once you start, it's hard to quit.

The second is due to the needs of work and life, and some people's work needs make people have to smoke and socialize.

The third is the impact of the environment on people, many.

People are told or seen to smoke by people next to them (including parents and relatives) from an early age, because it is normal to smoke when they grow up, and they will involuntarily try to smoke when they grow up. There are also people who try it out of curiosity, but because of the first point about smoking, it is addictive. So that's it.

Hope this helps.
