This special report on drugs examines, in turn, the supply and demand for psychotropic substances, the AIDS problem, and a review of ten years of efforts to combat drug addiction (the Trautmann Report). In addition, the report covers the Strasbourg Congress, where several European drug prevention initiatives were presented (notably: P.R.O.P.I.L.E. from the C.D.E.S. in Rennes, and “Allo parents adolescents!” from A.D.A.T.O. (Association for Assistance to Youth in Difficulty) in Yvelines).
