What in cigarette smoke is harmful? To know the right answer
Smoking leads to development of three basic diseases with a lethal outcome: a lung cancer; a chronic bronchitis and an emphysema; coronary illness. For a example, of the several countries in which smoking became a mass habit for a long time already, it has been proved that tobacco is at the bottom of death rate: * From a lung cancer in 90 % of all cases, * From a bronchitis and an emphysema in 75 %, * From a heart trouble in approximately 25 % of all cases. Approximately 25 % of regular smokers of cigarets will die prematurely because of smoking. Many of this number could live for 10, 20 or 30 years longer, i.e. in this case average loss of years of life is essential. Died owing to smoking on the average will lose years of the life. In one European country (with the population approximately in 50 million persons) number died owing to smoking is equivalent to a death toll as a result of air crashes of jet high-capacity liners if to assume that such accidents - onboard - will daily occur to destruction of all people.
