However, efforts to provide insight into the different aspects of Europe’s illicit drug problems have largely focused on indicators developed to assess demand-side strategies. The development of measures capturing dimensions of the supply of different illicit substances is an emerging field in the EU. To advance these efforts, the European Commission DG Justice, Freedom and Security commissioned RAND Europe to recommend indicators for improving the understanding of illicit drug markets, supply-reduction efforts, and drug- related crime in the EU. This document presents the results of this effort. We anticipate that this document will be of interest to policymakers from the European Commission, as well as other governmental bodies which are concerned with measuring the effectiveness of their drug supply-reduction strategies. It will also be of interest to law enforcement agencies, forensic laboratories and international organisations focusing on drug markets and organised crime. We believed it will also be a valuable resource for researchers with a specific interest in the policy analysis of drugs markets. RAND Europe is an independent not-for-profit policy research organisation that aims to serve the public interest by improving policymaking and informing public debate. Its clients are European governments, institutions and firms with a need for rigorous, impartial, multidisciplinary analysis.
