Mark Haden
Researcher; Psychedelic Policy Analyst; University of British Columbia
Canadian public health researcher and MAPS Canada executive director whose harm reduction framework for regulating psychedelics has become one of the most-cited policy models for jurisdictions considering legalization or decriminalization.
Biography
Mark Haden is a public health researcher and adjunct professor at the University of British Columbia's School of Population and Public Health who has become one of the most influential voices in psychedelic policy design. He is the Executive Director of MAPS Canada and has spent decades developing harm reduction frameworks for drug policy, including a systematic regulatory model for psychedelic substances.
Haden's most significant policy contribution is his regulatory framework for psychedelics, developed through peer-reviewed publications and policy papers, which proposes a tiered regulatory approach to psychedelic substances based on risk, context, and use pattern rather than blanket criminalization or unregulated access. His framework has been widely cited by policy researchers, legislators, and advocacy organizations in Canada, the United States, Australia, and Europe working to design regulatory approaches for psilocybin, MDMA, and other psychedelics.
His work is explicitly grounded in public health harm reduction principles — the same framework that has shaped successful drug policy in Portugal, Switzerland, and other countries. Haden argues that the choice between criminalization and commercialization is a false binary, and that well-designed regulatory frameworks can provide safe access while minimizing the harms of unregulated use.
Haden has contributed to Canada's evolving regulatory landscape for psychedelics, including providing testimony and expert input to Health Canada as it has developed special access and exemption pathways for psychedelic-assisted therapy. Canada's regulatory environment has been more permissive than the US in certain research and clinical access dimensions, and Haden's policy work has contributed to opening those pathways.

Why They Matter to the LearnShrooms Community
As more jurisdictions consider how to regulate psilocybin and other psychedelics, rigorous policy frameworks grounded in public health evidence become essential. Haden's regulatory model provides a practical template that goes beyond advocacy to actual regulatory design — exactly what legislators and health authorities need as they work through the policy mechanics of psychedelic access.
