How they work
EMBARK
Core mechanism: Six domains the model holds to be common in psychedelic states organize preparation and integration; four 'care cornerstones' are meant to keep delivery ethical, trauma-informed, and culturally responsive. The structure organizes the therapy rather than explaining how psychedelics work.
Ontology: A whole person whose psychedelic experience activates multiple dimensions simultaneously (existential, somatic, relational, affective-cognitive) requiring a multi-domain therapeutic response rather than a single-mechanism model
Psychedelic Harm Reduction & Integration (PHRI)
Core mechanism: Therapy that begins after the experience is over: the therapist neither supplies nor endorses the substance, and works with whatever the person came back with, whether insight, fear, confusion, or a changed sense of their life
Ontology: Psychedelic experiences can activate deep psychological material that requires skilled therapeutic support to integrate: without integration, the experience remains unmetabolized and potentially destabilizing

What each assumes — and misses
EMBARK
Philosophical roots: Grof (non-ordinary states); James (varieties of religious experience); harm reduction philosophy; CBT, ACT, and psychodynamic traditions integrated
Blind spots: Developed within a pharmaceutical research context (Cybin); limited independent replication; open-source status means variable implementation quality; requires specialized training not yet standardized across programs
Therapeutic voice: You keep coming back to what your body was doing when it started. Let's stay there a while before we go to what it meant.
Psychedelic Harm Reduction & Integration (PHRI)
Philosophical roots: Zinberg (drug, set, and setting); Grof (non-ordinary states as data); Rogers (unconditional positive regard applied to substance use experiences); harm reduction philosophy (Marlatt); James (varieties of religious experience); contemplative traditions
Blind spots: Minimal controlled research; risk of implicitly endorsing illegal substance use; boundary challenges when clients seek substances through therapist; limited training standards; can attract clinicians with ideological rather than clinical orientation to psychedelics
Therapeutic voice: I'm not here to tell you whether to do it again. I do want to know what you were hoping for, and whether any of it stayed with you.
Choosing between them
EMBARK and Psychedelic Harm Reduction & Integration (PHRI) both sit within the Psychedelic tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
