What it is necessary to know about harm of smoking?are told About harm of smoking much. However the concern of scientists and doctors caused by distribution of this addiction grows as still considerable number of people does not consider smoking unhealthy. Smoking - not harmless occupation which can be given up without efforts. It is the real drug addiction and the more so dangerous that many do not take seriously.
Nicotine - one of the most dangerous poisons of a phytogenesis. Birds (sparrows, pigeons) perish if to their beak only to bring the glass stick moistened with nicotine. The rabbit perishes from 1/4 drop of nicotine, a dog - from 1/2 drop. For the person the lethal dose of nicotine makes from 50 to 100 mg, or 2 - 3 drops. Such dose comes daily to blood after smoking of 20 - 25 cigarettes (one cigarette contains about 6 - 8 mg of nicotine from which 3 - 4 mg get to blood). The smoker does not perish because the dose is entered gradually, not in one step. Besides, the part of nicotine neutralizes formaldehyde - other poison which is contained in tobacco. Within 30 years such smoker smokes about 20000 cigarettes, or 160 kg of tobacco, absorbing on average 800 g of nicotine.
Systematic absorption of small, nonlethal doses of nicotine causes a habit, addiction to smoking. Nicotine joins in the processes of an exchange happening in a human body and becomes necessary. However if the non-smoking person in one step receives a considerable dose of nicotine, there can occur the death. Such cases were observed in the different countries. Our outstanding scientist - the pharmacologist N. P. Krafkov described death of the young man after he for the first time in life smoked a big cigar. In France, in Nice, as a result of the competition “ Who will smoke " more; two “ winners “ having smoked 60 cigarettes, died, and other participants with a serious poisoning were hospitalized. In England the case when it is long the smoker 40 - the summer man at night is registered, during a hard work, smoked 14 cigars and 40 cigarettes. In the morning to it became badly, and, despite the provided medical care, he died. The case when to the room where tobacco in sheaves in powder lay, put is described to sleep the girl and she in several hours died.
The children living in the smoked rooms more often and have diseases of respiratory organs more. At children of the smoking parents within the first year of life the frequency of bronchitis and pneumonia increases and the risk of development of serious diseases increases. The tobacco smoke detains solar ultraviolet rays which are important for the growing child, influences a metabolism, worsens comprehensibility of sugar and destroys the vitamin C necessary for the child during growth. At the age of 5 - 9 years at the child function of lungs is broken. Thereof there is a decrease in abilities to the physical activity demanding endurance and tension.
Having examined over 2 thousand children living in 1820 families, professor S. M. Gavalov revealed that in families where smoke, at children, especially at early age, frequent acute pneumonias and acute respiratory diseases are observed. In families where there were no smokers, children were almost healthy. Children whose mothers smoked during pregnancy have a predisposition to attacks. They get sick with epilepsy much more often.
The children who were born from the smoking mothers lag behind the peers in intellectual development. So, scientists of GDR V. Gibal and H. Blyumberg at inspection of 17 thousand such children revealed lag in reading, the letter, and also in growth. Considerably the quantity of allergic diseases increased. By the Soviet and foreign scientists it is established that nicotine and dry particles of a tobacco smoke possesses allergiziruyushchy action. They promote development of many allergic diseases in children, and the less child, the does bigger harm to its organism a tobacco smoke.
Smoking of teenagers, first of all, affects on nervous and warm - vascular systems. In 12 - 15 years they already complain of short wind at physical activity. As a result of long-term supervision the French doctor Dekalzne came to the conclusion 100 years ago that even insignificant smoking causes in children an anemia, disorder of digestion. Smoking negatively influences progress of the school student. The number of poor increases in those classes where there are more smokers. Smoking of school students slows down their physical and mental development.
The state of health undermined by smoking does not allow to choose an occupation to liking, to achieve success (for example, to become young men pilots, astronauts, athletes, to girls - ballerinas, singers, etc.) . Smoking and the school student are incompatible. School days are years of growth both physical, and intellectual. The organism needs many forces to cope with all loadings. It is known that skills, the habits got at school age, the strongest. It belongs not only to useful, but also to addictions. The earlier children, teenagers, young men, girls will get acquainted with smoking and will begin to smoke, the quicker will get used to it, and further it will be very difficult to refuse smoking.
Foreign tobacco monopolies advertize cigarettes with the smaller content of nicotine and pitches as “ harmless to an organism “. About it the CEO of National institute of cancer diseases doctor A. Upton (USA) noticed that that which does not burn can be considered as a nontoxical cigarette.
