Executive Director
Sam Chapman
Founder & Executive Director, Center for Psychedelic Policy
Sam Chapman is one of the country’s leading experts on state-based psychedelic policy and access programs. He served as Campaign Manager for Oregon’s Measure 109—the nation's first successful ballot measure to create a legal framework for psilocybin therapy—and later helped guide early implementation efforts. Over the past decade, Sam has advised lawmakers, regulators, advocates, and philanthropists across the country on psychedelic policy reform.
In 2025, Sam founded the Center for Psychedelic Policy (CPP) to solve one of the most urgent and overlooked challenges in the field: affordability. CPP is currently in the process of becoming a 501(c)(3) nonprofit organization. Under Sam’s leadership, the Center launched the National Psychedelic Landscape Assessment (NPLA)—the first comprehensive analysis of state legislation and policy trends focused on access, implementation, and public investment.
Sam’s work is grounded in a belief that real-world healing requires real-world access—and that affordability must be the foundation of any scalable policy model. He regularly partners with legislators, funders, and researchers to design pragmatic strategies that work in today’s political environment.
