With a regional seminar organised on 22-23 February 2019 in Tangier, the Ministry of Health of the Kingdom of Morocco and the Pompidou Group celebrated 10 years of the introduction of opioid agonist treatment in the country. Taking place within the 2019 MedNET work programme, the seminar brought together addiction treatment centers from across the Kingdom of Morocco, as well as experts from Tunisia, Jordan, Portugal and Switzerland - which just joined MedNET as its 16th member country. The presentation of the recent Pompidou Group publication on opioid agonist treatment guiding principles for legislation and regulations by Swiss experts and its translation to Arabic language were well appreciated by the participants. The lively discussions were also enriched by testimonies of drug users who shared their experiences as beneficiaries of risk reduction measures and opioid agonist treatment in Morocco. One of the main outcomes of the seminar was the proposal to set up a network of professionals working in the different addiction treatment centers in the country, in order to exchange knowledge and expertise, harmonise practice, elaborate guidelines, share data and collaborate with the Moroccan Monitoring Center on Drugs and Drug Addiction with the aim of improving communication between practice (professionals), research (data collection) and policy (Ministry of Health).
