The Best practice portal is a resource for professionals, policymakers and researchers in the areas of drug-related prevention, treatment, harm reduction and social reintegration. The portal concentrates on illicit drugs and polydrug use and has a clear European focus. It is continuously updated as information and research on interventions emerges.

You can find the latest evidence (what works and what doesn't work) - guidelines, standards and tools (instruments and questionnaires).

‘Best practice is the best application of available evidence to current activities in the drugs field.
• underlying evidence should be relevant to the problems and issues affecting those involved(professionals, policymakers, drug users, their families);
• methods should be transparent, reliable and transferable and all appropriate evidence should be considered in the classification process;
• experience in implementation, adaptation and training should be systematically collected and made available;
• contextual factors should be studied by modelling different prevalence levels so as to assess the impact of an intervention on the population; and
• evidence of effectiveness and feasibility of implementation should both be considered for the broader decision-making process.'
