The promotion of effectiveness and best practices are emphasised in the Hellenic policy documents, while the development of national guidelines in the field was provided for in the last law relating to drugs, enacted in 2013. There is no formal and uniform quality assurance system for drug demand interventions at the national level. Each of the main drug demand reduction organisations has developed its own system to assure and enhance the quality of its services. Accreditation and/or certification are not prerequisites for professionals, services or drug demand reduction programmes in Greece.
However, there are specifications and criteria for the operation of Prevention Centres and certain standards based on which the Prevention Centres prepare their five-year activity plans.
In 2011, a handbook entitled Drug prevention: guidelines and intervention planning was issued, which was intended to assist prevention professionals in planning and evaluating their interventions. In-depth evaluations of prevention programmes remain rare. With a view to promoting quality standards in drug prevention, the University of Mental Health Research Institute and the Greek national focal point for the EMCDDA participated in the EU Prevention Standards Partnership, which has been undertaking Phase II of the European Drug Prevention Quality Standards Project.
Each specialised therapeutic agency has developed its own operational framework to assure and enhance the quality of its services. In 2013, a new operational framework for opioid substitution treatment programmes was published.
The Organisation Against Drugs (OKANA) Training and Supervision Centre provides seminars for practitioners in the demand reduction field as well as for law enforcement officers. In 2016, the Icarus Prevention Unit (KETHEA), in cooperation with the Law Schools of the Aristotle University of Thessaloniki and of the University of Nicosia, launched an 18-month post-graduate training programme on criminal law and addiction, as well as providing training seminars for drug demand reduction practitioners, researchers, students and other groups.
