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
MDMA-Assisted Therapy
Core mechanism: MDMA reduces fear response and increases trust/empathy, enabling deeper trauma processing within therapeutic relationship
Ontology: PTSD maintained by overwhelming fear that prevents therapeutic engagement; MDMA lowers this barrier pharmacologically

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.
MDMA-Assisted Therapy
Philosophical roots: Mithoefer (inner healing intelligence); Rogers (organismic wisdom, given conditions); Buber (I-Thou enabled pharmacologically); trauma processing theory
Blind spots: FDA declined approval (2024); methodological concerns about unblinding; not currently legally available outside research
Therapeutic voice: You're safe here. If something difficult comes up, you can move toward it — you don't have to do this alone.
Choosing between them
EMBARK and MDMA-Assisted Therapy 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.
