For more than 20 years, the European information network on drugs and drug addiction (Reitox), has been the cornerstone of the European drug monitoring and reporting system, to which it contributes by collecting, analysing, interpreting and disseminating data at national level, as well as by defining the tools for monitoring. Reitox is a partner and an integral part of the EMCDDA, a key player at EU and international level. The Reitox network currently includes the 28 EU Member States plus Turkey, Norway and the European Commission.
