How they work
EMBARK
Core mechanism: Structured attention to the six domains that emerge in psychedelic states enables integration of the experience into lasting psychological change, while the four care cornerstones ensure ethical, trauma-informed, culturally competent delivery
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: Non-judgmental therapeutic space for processing psychedelic experiences enables integration of insights into daily life, resolution of challenging material, and meaning-making from non-ordinary states
Ontology: Psychedelic experiences can activate deep psychological material that requires skilled therapeutic support to integrate — without integration, the experience remains unmetabolized and potentially destabilizing

Both treat
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: Which of these domains felt most alive during your experience? Let's start there.
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: Tell me about the experience. What came up for you? There\'s no wrong way to have processed that.
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.
