Episode notes
Ibogaine’s Broad, Pleiotropic Pharmacology
- Ibogaine is a broad-acting compound that interacts with many neurotransmitter systems rather than a single receptor target.
- This pleiotropic action may explain its strong, multi-domain therapeutic effects compared with single-target drugs.
Life-Review Experience Rewrites Traumatic Memories
- Users report a prolonged introspective 'life review' during ibogaine that recontextualizes emotionally salient memories.
- That reconsolidation-like process appears to reduce trauma-related distress and change memory meaning.
Dopamine Reset Explains Anti‑Addiction Effects
- Ibogaine upregulates glial-derived neurotrophic factor and restores dopamine neuron health in the ventral tegmental area.
- Animal and targeted infusion studies suggest this dopamine reset can stop addictive self-administration behaviors.
