Regional and Country-Level Drug Observatories & Surveillance Systems

Around the world, national and regional drug observatories and surveillance systems generate essential data on substance use, treatment demand, drug markets, health harms, and policy responses. While regions such as Europe, the Americas, and Australasia benefit from well‑established and coordinated systems, others—particularly in parts of Africa—are still developing their data infrastructure. The global landscape is therefore rich but uneven, combining highly standardised regional platforms with more fragmented national systems, all of which play a vital role in informing evidence‑based policy, practice, and prevention efforts.
