Drug addiction and AIDS: highlights of the 1st European Congress.

The 1st European Congress on 'Drug Addiction and AIDS' was held in Vienna, Austria, February 21-23 1991. This conference represented scientists from all areas of Europe and North America. The co-ordinators and the international scientific board offered an exciting programme with eight workshops in clinical, medical and management tracts; there were four plenary sessions with international, national and local experts, exhibits and receptions. With the impact of AIDS and the changes in Eastern Europe, we must now, more than ever before, rethink our strategies to improve effective treatment for substance abusing patients.
