This short paper concerns the association of suicidal with other psychosocial phenomenas such as alcoholism and depression. Some investigators have observed and studied this phenomenon specially among practitioners of liberal professions such as lawyers and medical doctors. Those professions are particuliarly stressing and thus favour the combination of two other interrelated comorbidities: depression and abuse of alcohol. We suggest our own hypothesis to explain those multiplied risks. Alcohol would not only add its own effect of depression on the central nervous system, it would multiply by potentialization the depressive effect of the first agent. And as a result, the abuse of alcohol does cause a corresponding increase of suicidals.
