Evaluation is essential for effective policymaking, helping ensure that policies and programmes have the desired effect, provide value for money and do not have negative unintended consequences. The importance of evaluation has been recognised in all EU drug strategies and in the strategies of many Member States.

To support those considering or involved in commissioning, managing or undertaking policy evaluations, this page provides access to a range of materials, including a 7-step guide, examples of strategies and evaluations in Europe and potentially useful data sources.
