About Psychedelic Science 2027
Psychedelic Science (PS27) is the flagship conference of the Multidisciplinary Association for Psychedelic Studies (MAPS). Held biennially, PS27 takes place at the Colorado Convention Center in Denver from May 3–7, 2027.
What to Expect
PS27 is the largest gathering of psychedelic researchers, clinicians, policymakers, and advocates in the world. The conference features peer-reviewed research presentations on psilocybin, MDMA, ketamine, and other psychedelic compounds, with a strong focus on clinical trial results, therapeutic protocols, and regulatory pathways. Previous editions have drawn 12,000+ attendees.
Why It Matters for BMS Readers
Psychedelic-assisted therapy represents one of the most significant shifts in mental health treatment in decades. Many of the clinical trials we track in our Research section — psilocybin for depression, MDMA for PTSD, ketamine for treatment-resistant conditions — present their latest data at this conference. If you follow the science of psychedelic medicine, PS27 is the definitive event.
