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
KAP
Core mechanism: Ketamine-induced neuroplasticity + dissociative state creates window for psychotherapeutic processing and new learning
Ontology: Treatment-resistant conditions involve rigid neural patterns; ketamine disrupts rigidity and opens plasticity window

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.
KAP
Philosophical roots: James (varieties of religious experience — altered states as data); Grof (non-ordinary states); neuroplasticity research; mystical tradition broadly
Blind spots: Regulatory fragmentation; limited standardization of psychotherapy component; risk of ketamine becoming the treatment rather than catalyst
Therapeutic voice: As the medicine takes effect, just notice what arises without directing it. We'll make sense of it together.
Choosing between them
EMBARK and KAP 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.
