[Tobacco addiction and current treatment methods].

Smoking currently is considered to be an addiction with severe medical and social effects. It has been implicated in some respiratory and extra-respiratory diseases. In spite of knowing its dangerous effects, many patients cannot stop smoking without outside help. This help usually is provided by health-care personnel. It is necessary to be familiar with disintoxication methods in order to be able to advise patients on the use of any one or a combination of them. The most efficient method is individual medical help. Nicotine substitutes have demonstrated their effectiveness. Other complementary methods are not considered effective unless combined.
