The recent increase in cocaine-related deaths and the dangers posed by organised crime’s participation in the distribution of extremely dangerous synthetic opioids underline the importance of access to the timely and accurate data made available through participation in the EMCDDA’s network of national drug monitoring centres. Recent advances in tackling drug-related organised crime in Scotland through multiagency collaboration has been dependent on access to good-quality epidemiological and supply information. As the trade in illicit drugs is by its nature international and largely hidden, linking this information to the wider European picture is essential if decisions are to be based on evidence.

The EU Early Warning System on new psychoactive substances has been highly successful at detecting new drugs, accurately describing their characteristics and potential dangers, and sharing this information effectively so that the knowledge gained through this system can inform the response of all member states. The recent re-establishment of Ireland’s Early Warning and Emerging Trends network allow us to contribute and learn from this rich source of information.

Through its participation in the EMCDDA, the UK has made a significant contribution to our understanding of the European drugs situation and its implications for public health and security and the capacity of member states to respond quickly to new developments, identify and implement responses supported by evidence, and evaluate policies and strategies. Severing this link with European institutions may well have public health and security consequences and cause lasting damage to the UK’s ability to manage these harms.
