Council Regulation (EEC) No 302/93 on the establishment of a European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) had to be recast to keep abreast of new developments in the European Union (EU). The regulation also needed updating so as to extend the centre's role to the investigation of new trends in drug use, especially poly-drug use, where illicit drugs are taken in combination with legal drugs or medication.
Il apparaît également indispensable d'actualiser ces normes pour étendre le rôle de l'OEDT à l'examen des nouvelles tendances en matière de consommation de drogue, et en particulier de la polyconsommation, y compris la consommation simultanée de drogues illicites et de drogues licites ou de médicaments.
