Cost$4,000-$12,000 per treatment$10,000-$15,000 for full protocol
Experience TypeIntense, introspective, visionaryEmpathogenic, warm, connective

Mechanism of Action

🧠 Ibogaine

  • NMDA antagonist — resets glutamate system
  • Opioid receptor modulation — interrupts addiction pathways
  • Serotonergic activity — 5-HT2A agonist (psychedelic effects)
  • GDNF upregulation — promotes neuronal healing
  • Sigma receptor activity — neuroprotective effects

💜 MDMA

  • Serotonin flood — massive release + reuptake inhibition
  • Oxytocin release — bonding, trust, emotional openness
  • Amygdala suppression — reduces fear response to trauma memories
  • Prefrontal cortex activation — enhances processing and reappraisal
  • Neuroplasticity — temporary window for memory reconsolidation

Clinical Applications

Best Ibogaine Candidates

  • Opioid addiction (heroin, fentanyl, prescription opioids)
  • Stimulant addiction (cocaine, methamphetamine)
  • Alcohol use disorder
  • Treatment-resistant depression with addiction
  • PTSD with substance use

Best MDMA Candidates

  • PTSD (especially relational/developmental trauma)
  • Social anxiety in autism spectrum
  • End-of-life anxiety
  • Couples therapy (bonding and communication)
  • Treatment-resistant PTSD without active addiction

Overlap Conditions

Both therapies show promise for:

  • PTSD (MDMA has more research, ibogaine may be useful for complex trauma + addiction)
  • Treatment-resistant depression (different mechanisms)
  • Anxiety disorders

Treatment Protocols

Ibogaine Protocol

Single flood dose (15-25 mg/kg) over 24-36 hours

  • Pre-treatment: Cardiac screening, taper off contraindicated meds
  • Treatment: Continuous medical monitoring, quiet dark room
  • Post-treatment: 3-7 days recovery at clinic
  • Aftercare: Integration therapy, 6-12 months
  • Boosters: Optional at 3-12 month intervals

MDMA Protocol

3-session course over 8-12 weeks (120-180mg per session)

  • Preparation: 3 therapy sessions to build rapport, set intentions
  • Session 1: MDMA + 8 hours therapy (4-6 hours active)
  • Integration: 2-3 therapy sessions processing session 1
  • Sessions 2 & 3: Repeat at weeks 4 and 8
  • Follow-up: 3 integration sessions post-treatment

Safety & Contraindications

Ibogaine Contraindications

  • Cardiac conditions (prolonged QT, arrhythmias, heart failure)
  • Severe liver/kidney disease
  • Seizure disorder
  • Active psychosis
  • Pregnancy/breastfeeding

MDMA Contraindications

  • Cardiovascular disease (caution, not absolute contraindication)
  • Active psychosis or mania
  • Seizure disorder (relative contraindication)
  • Taking MAOIs or SSRIs (serotonin syndrome risk)
  • Severe liver disease

Success Rates

Ibogaine for Addiction

  • 50-65% abstinence at 12 months (with aftercare)
  • 80-95% withdrawal elimination within 24 hours
  • 70-80% report significant craving reduction

MDMA for PTSD

  • 67% no longer meet PTSD criteria after 3 sessions (FDA trial)
  • 88% clinically significant symptom reduction (Stanford MISTIC study)
  • Effects maintained at 12+ month follow-up

Legal Status & Access

Ibogaine

  • US: Schedule I (no legal access)
  • Mexico: Legal, unregulated
  • Canada: Unscheduled (clinics operating)
  • Netherlands: Legal in some contexts
  • New Zealand: Legal, prescribed medicine

Most patients travel to Mexico or Costa Rica for treatment.

MDMA

  • US: FDA-approved for PTSD (August 2024), Schedule III
  • Available through: Certified therapists, MAPS protocol
  • Canada: Available via Special Access Programme
  • Australia: Approved for PTSD (2023)
  • EU: Approved in some countries (Switzerland, Netherlands)

Legal access expanding rapidly post-FDA approval.

Which Is Right for You?

Choose Ibogaine If:

  • Primary concern is addiction (especially opioids)
  • You want rapid withdrawal elimination
  • You prefer a single, intensive treatment
  • You're willing/able to travel internationally

Choose MDMA If:

  • Primary concern is PTSD without active addiction
  • You prefer an FDA-approved, legal treatment
  • You want a gentler, more relational therapy experience
  • You can access a certified MDMA therapist

Both therapies can be transformative when used appropriately. Consult qualified medical professionals to determine the best approach for your situation.
