The international discussion surrounding cannabis regulation has evolved considerably in recent years. What was once viewed primarily through the lens of criminal enforcement or domestic political debate is increasingly being addressed as a matter of public health, patient care, scientific rigour, and regulatory governance.
Convened in London, the 2026 Summit brought together participants representing nearly 30 countries and 20 regulatory jurisdictions for practical, forward-looking dialogue on the governance frameworks, scientific standards, operational safeguards, and coordination mechanisms required to support credible and responsible cannabis oversight across both established and emerging regulatory environments.
The white paper reflects perspectives from regulators, policymakers, physicians, researchers, patients and patient advocates, standards experts, and legal practitioners. Its findings are offered not as conclusions but as a continuation of the process of learning and coordination that began at the 2025 Summit in Washington, D.C., and that carries into the 2027 Summit in Zürich.
