Why EMBARK

Six domains, one whole person

Earlier models of psychedelic therapy left real gaps: they were often built for one drug or one diagnosis, said little about the body or the relationship, and offered limited ethical guardrails. EMBARK was designed to bridge those gaps, a model that centers ethics, works across medicines and diagnoses, and meets the whole person.

The approach is described in EMBARK Psychedelic Therapy for Depression (Oxford University Press, 2024) and in peer-reviewed research. Its six clinical domains give therapists a shared map for what arises in psychedelic treatment.
