The body gets used for nicotine that is known of the life experience: the amount of nicotine that an average smoker consumes, of course, would have caused poisoning to the usual person. Cigar weighing 6 g contains 0.3 g of nicotine. If an adult swallow such a cigar, he may die; 20 cigars or 100 cigarettes per day can also cause death from smoking. An interesting fact is that the leech posed to the smokers will soon fall off into convulsions and dies of sucked human blood, containing nicotine.
The paradox is that smoking people do not die from nicotine because the dose received by the smoker is too small to do this. Numerous other deadly diseases are caused by more harmful substances: there are about four thousands of them in smoke. Nicotine causes a person to smoke. Some experts in the field of tobacco dependence consider it as the most potent addictive drug, which is in the same group with heroin and cocaine. Nicotine acts through receptors in the joints of the nerve cells in the brain and muscle tissue. These receptors recognize it instantly as soon as it enters the body. As a result, there is a distortion of the nervous impulse that controls the state of vessels, muscles, glands of external and internal secretion. When receptors signal the presence of nicotine, blood pressure increases and peripheral circulation slows. The waves in the brain change and impetus to a number of endocrine and metabolic effects is given.
Mental and physical health of the smoker, as well as the situation in which smoking occurs, can cause a feeling of relaxation and cheerfulness. In stressful situations, a cigarette has a calming effect, and in a situation of relaxation as a stimulant. Once the body gets used to a certain level of nicotine in the blood, it will seek to maintain it, and the man again reaches for a cigarette.
One another action of nicotine is a stimulant of breath. By the way, nicotine has the property to cause the so-called withdrawal. With long-term use, as is the case of a smoker, nicotine ceases to stimulate respiration and causes discontinuation with its depression. It is related with discomfort that a person experiences when quitting smoking.
Unfortunately, smoking is harmful not only to the person who is addicted to tobacco, but also those around him. Passive smokers, according to numerous studies, only 1.5 times less likely to suffer from the effects of other people smoking than smokers themselves.
