Nicotine addiction


What is nicotine addiction?

Nicotine is a poisonous alkaloid derived from leaves and tobacco seeds (Nicotiana tabacum), a very strong poison. It is with him associated with the development of dependence on tobacco in heavy smokers. In small doses, nicotine has a stimulating effect on the autonomic nervous system of a person. Along with carbon and hydrogen contains nitrogen and has an alkaline reaction. When nicotine gets into the body, regular heartbeats increase heart rate, increase blood pressure, narrow the blood vessels, reduce appetite. Under its influence in the blood, the content of cholesterol and fatty acids increases. In large doses, nicotine causes paralysis of the ganglia of the autonomic nervous system.

The greatest amount of nicotine a person receives during smoking. With the smoke of a cigarette, a cigar or a tube, about 30% of the nicotine in them is released. When smoking, about 95% of the nicotine contained in the smoke enters the body. In the body nicotine is quickly broken down. Nicotine dependence develops very quickly. However, nicotine is only one component of tobacco, which contains more than 3,800 other substances. Even before the end, it is not known what effect many of them have on the human body. Thousands of studies have been carried out to prove that smoking causes many diseases, for example, malignant tumors or diseases of the circulatory system. Producers of tobacco products are constantly arguing, proving that there is no direct connection between these diseases and tobacco.

Causes of nicotine dependence

Psychological nicotine addiction occurs when smoking becomes a habit. For many smokers, smoking is a kind of ritual. With a cigarette or a tube in their mouth, they feel more confident. Some believe that smoking helps them relax (although in fact it is not). In addition to psychological, there is also physical dependence. Many smokers who try to quit smoking have withdrawal symptoms. Often such people (especially women) after a while start to smoke again.

Aldehydes, phenols, acids and ammonia irritate the mucous membranes and eventually cause chronic bronchitis (smoker's bronchitis) and chronic gastritis.
