The promotion of effectiveness and best practices is emphasised in the Hellenic policy documents, while the development of national guidelines in the field is addressed 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. In 2013, a new operational framework for opioid substitution treatment programmes was published.
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 guide their 5-year activity plans.
A handbook entitled Drug prevention: guidelines and intervention planning was published in 2011 to assist prevention professionals in planning and evaluating their interventions. Nevertheless, 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.
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, KETHEA, in cooperation with two law schools, launched a postgraduate programme on criminal law and addiction. It also provides training seminars for drug demand reduction practitioners, researchers and students. In addition, the Greek focal point to EMCDDA promotes quality assurance in the drug demand reduction field in Greece through seminars, publications, participation in evaluation studies and presentations at national congresses.
