G2 : Educational advises group (N = 100) : Participants in this group benefit of brief educational advises (10 minutes interview maximum), and received a pamphlet on the health effects of alcohol and tobacco consumption.

It did not seem possible to evaluate patients without offering them the possibility of a low threshold intervention.
