We owe a large debt to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) in Lisbon for the relevant input and support we received on many issues. The EMCDDA proved to be a particularly valuable source of information and expertise for our purposes. We want to express special thanks to Paul Griffiths, Brendan Hughes, Rosemary de Sousa and Frank Zobel who provided high quality information, data and advice throughout the project, as well as to their colleagues who contributed to specific sections in this report.
We would like to express thanks to all the experts from the countries covered in the individual country reports in the Appendix. They took the time to answer all our questions and provided valuable information on drug problems and policy in their countries.
We also would like to thank Jon Caulkins (Heinz School, Carnegie-Mellon University) for his useful comments and Jim Burgdorf (RAND) for his excellent research assistance to the Market Report. Thanks also to Greg Falconer and Philipp-Bastian Brutscher (RAND Europe) for their great assistance with the research for the economic cost report.
