The NAHRPP project (New Approaches in Harm Reduction Policies and Practices) is a joint project of the Transnational Institute (TNI), based in the Netherlands, ICEERS (Spain), Forum Droghe (Italy) and Diogenis (Greece), supported by the European Union. The project addresses recent drug policy developments in Europe. One section of this project, led by TNI, is focused on the role of local authorities in cannabis regulation. Local and regional authorities across Europe are confronted with the negative consequences of a persisting illicit cannabis market. Increasingly, local and regional authorities, non-governmental pressure groups and grassroots movements are advocating for regulation of the recreational cannabis market, rather than prohibition. This project analyses the possibility of cannabis market regulation models, alongside political, policy, and legal steps under exploration by local authorities in Belgium, Spain, Switzerland, Germany, Denmark and the Netherlands. It is hoped that the information collected through this initiative will help to improve the understanding of regulating drug markets as a means to reduce the negative consequences of illicit drug markets on individuals and society. In order to better understand the situation around, and possibilities for, local and regional cannabis regulation, a series of six country reports were developed, providing background for an overarching analytical report. The country reports provide detailed information about the state of cannabis policy, and the possibilities for change, within each country. These reports address the past, present, and future of cannabis policy domestically accross the EU.
