The Fireside Database: Large-scale evidence from 25,419 psychedelic support interactions.

Fireside Project’s Psychedelic Support Line dataset captures 25,419 US-based psychedelic peer support interactions (April 2021–February 2026), enabling multilevel modeling of supporter effects.

• Why it matters: Nonclinical psychedelic support is widespread, but there is no systematic evidence on who seeks help, under what circumstances, or what aspects of support relate to caller outcomes.
• What they did: The Fireside Database combines structured interaction logs, volunteer-coded metadata, and 2,777 caller satisfaction surveys across five outcome dimensions from 220 trained volunteers.
• The result: Psilocybin is reported in 59.9% of coded interactions, cannabis is linked to the highest distress rate at 47.2%, and the nested supporter structure supports multilevel analyses of supporter effects.
