How they work
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
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

What each assumes — and misses
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.
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
KAP 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.
