title: [Addictions and psoriasis: an example of the dermatologist's implication in preventive medicine ?].
abstract: Association between psoriasis and addictive disorders has been longtime suspected and several studies are supporting the association of psoriasis and alcohol, and of psoriasis and tobacco. The association of psoriasis and other addictive disorders has not yet been reported. The association of psoriasis and alcohol is not restricted to alcoholism (defined as excessive alcohol consumption with psychic and/or psychic (correction of physic) dependence). It has been suggested that psoriasis is more closely linked to alcohol misuse than it is to alcoholism. The association of psoriasis and alcohol seems not been influenced by the gender, and shows a dose-effect relation. The most striking link between cigarette smoking and psoriasis has been established in palmo-plantar pustulosis. This link also seems to exist for other forms of psoriasis, with a dose-effect relation. Cigarette smoking could be involved in the high prevalence of lung cancer and cardio vascular disorders in psoriatic patients. There are a number of difficulties in the assessment of the correlation between psoriasis, cigarette smoking, and alcohol, and even more so in establishing a causal or etiologic relationship between the three, because of several confusion factors. This must not occult the reality of this association and its impact of psoriatic patients' health and the importance of detecting and preventing them. The detection and the prevention of the complications of these addictions belong to the dermatologists.
