About
Portland Psychedelic Society (PPS) is arguably the most active psychedelic society in the United States. As a 501(c)(3) nonprofit with 11,000+ members as of 2026, PPS hosts 30+ monthly meetings covering integration, education, and community building — extraordinary volume that makes PPS the de facto blueprint for what fully-developed psychedelic community infrastructure looks like.
Portland’s status as home to the nation’s first licensed psilocybin program (Measure 109) makes PPS a critical community hub where licensed facilitators, clients of Oregon service centers, and curious community members intersect. The density of programming reflects Portland’s per-capita position as the densest psychedelic community infrastructure in the U.S. when combined with Cascade Mycological Society and the Psychedelics in Recovery chapter.
Why It Matters
If you want to understand what fully-developed psychedelic community infrastructure looks like in 2026, PPS is the case study. With 11,000+ members and 30+ monthly meetings, the density of programming sets the ceiling other cities aspire to. The Global Psychedelic Society Locator credits PPS as the operating template that 100+ independent societies worldwide reference when building their own programs.
