As a rule, applied to the use of smoking mixtures possessing narcotic properties (tobacco, cannabis, marijuana, opium, crack, etc.) due to the rapid flow of saturated substance of blood to the head brain.It is clearly shown that the major toxic effects exerted by smoking constituents on health occur in the respiratory tract (bronchitis chronic emphysema and lung cancer, bronchial) and the cardiovascular system atherosclerosis, coronary artery disease, high blood pressure) (Shaper,78).

These conditions are largely prevalent among people who smoke more than a pack of cigarettes a day have three times more sick leave and spend up to 15% more bed days per year than non-disease smokers.

Three classic studies led to the conviction of the existence of a causal link between smoking and lung cancer (Shaper,78).

The age of onset of smoking Tabacal daily amount smoked, the depth of the inhalation, type of cigarette use were factors subject to study and obtained figures categorical dose-response (Kenneth, 36).
