The EMCDDA and the European Commission have been asked to prepare a proposal for key indicators for the drug supply area. Two technical conferences supported by expert working groups in three areas (drug markets, drug supply reduction and drug-related crime) recognised that:
· we should build on the ongoing work in this area at the national, European and International level, adopting a developmental approach coherent with national realities and needs;
· routine reporting needs at EU level should be based upon a restricted set of core data.
