As a global team of passionate change-makers, the Global Psychedelic Society (GPS) supports psychedelic societies across the world helping advocate for the responsible use of psychedelic substances for personal and collective growth, healing, and spiritual exploration.

To support our mission, we collaborate with allies in social, political, and scientific institutions, and work towards changing existing laws and policies to promote research and safe access to psychedelic substances.

Through the power of community, we seek to shift the cultural dialogue surrounding psychedelics towards more compassionate and productive narratives.
