Key Outcome Statistics

Figures drawn from peer-reviewed observational studies and clinical trials in medically supervised settings.

50%
Opioid-Free at 1 Month (Obs. Study)

25/33
Withdrawals Resolved Within 24h

Alper et al. (1999): resolution of opioid withdrawal signs within 24 hours in 25 of 33 treatments, sustained through at least 72 hours.

80%
Withdrawal Eliminated or Drastically Reduced

Davis et al. (2017): in a survey of 88 people who took ibogaine for opioid problems, 80% reported withdrawal symptoms eliminated or drastically reduced.

88%
PTSD Symptom Reduction

Stanford MISTIC trial (n=30 veterans) showed 88% average PTSD reduction at 1-month follow-up.

90%
Patient-Reported Success (Beond)

9 of 10 patients at Beond Health (6,000+ treatments) report the treatment worked. 100% treatment retention.

Published Research

Key peer-reviewed studies informing current clinical understanding of ibogaine outcomes.

Köck et al. (2022) — Journal of Substance Abuse Treatment (Systematic Review)

A systematic review of 24 studies covering 705 ibogaine-treated patients concluded that ibogaine and noribogaine show potential to reduce withdrawal severity and craving, while emphasizing cardiac risk (QT prolongation) and the absence of randomized controlled trials. No validated long-term abstinence rate exists in the published literature.

Cherian et al. (2024) — Nature Medicine (Stanford MISTIC)

The landmark Stanford MISTIC trial treated 30 Special Operations veterans with magnesium-ibogaine for PTSD and TBI. Results: 88% average PTSD symptom reduction, 87% depression reduction, 81% anxiety reduction at 1 month. WHODAS disability scores dropped from 30.2 to 5.1 (effectively no disability). Remission at 1 month: 86% (PTSD), 83% (depression), 83% (anxiety). No unexpected or serious adverse events were reported. Open-label, no control group.

Ibogaine vs. Traditional Treatments

How ibogaine compares to medication-assisted treatment (MAT), 12-step programs, and residential rehab across key dimensions.

Success Rates by Substance Type

Ibogaine's effectiveness varies significantly by substance. Opioids show the strongest evidence; other substances have promising but more limited data.

SubstanceMechanism1-Month Outcomes12-Month OutcomesEvidence Level
Opioids (heroin, fentanyl, Rx)Direct mu-opioid receptor reset + withdrawal elimination50% no opioid use (obs. study)Improvements sustained (obs.)Strongest available (observational)
AlcoholGABA/glutamate modulation + craving reductionNo published human outcome rateUnstudiedPreclinical + small open-label trial
Cocaine / StimulantsDopamine pathway neuroplasticity + psychological insight61% abstinent at interview (n=75 retrospective)Median 5.5 mo abstinence after one sessionLimited (retrospective, Schenberg 2014)

Depression / AnxietySerotonin modulation + neuroplasticity + psychological processing87% / 81% reductionUnder investigationModerate (Stanford MISTIC)

Why opioids respond best: Ibogaine has a unique direct action on mu-opioid receptors — it literally resets them to a pre-addiction state while eliminating acute withdrawal. For non-opioid substances, the benefit comes primarily through neuroplasticity (growing new neural connections via GDNF/BDNF), dopamine system modulation, and the profound psychological insight that facilitates behavioral change. This is why aftercare and integration therapy become even more critical for non-opioid addictions.

How Aftercare Affects Success Rates

Ibogaine creates a “window of opportunity” — reduced cravings and enhanced neuroplasticity — that structured aftercare converts into lasting recovery.

Weakest
No Aftercare

Ibogaine session only, no follow-up therapy or support. Patients return to unchanged environments and social triggers. Relapse risk is highest in the first months. No study has quantified aftercare tiers — these are clinical observations.

Stronger
Basic Aftercare

Weekly therapy sessions and peer support groups for 3+ months post-treatment. Addresses psychological triggers but may miss environmental and social factors.

Strongest
Comprehensive Aftercare

Structured 6-12 month integration program: weekly therapy, integration coaching, lifestyle restructuring, support groups, family counseling, and regular check-ins. Best long-term outcomes.

What Effective Aftercare Includes

+Weekly individual therapy (CBT, somatic, EMDR)
+Integration coaching (processing ibogaine insights)
+Peer support groups (NA, SMART Recovery)
+Family/relationship counseling
+Lifestyle restructuring (exercise, nutrition, sleep)
+Environmental change planning
+Regular medical check-ins (3, 6, 12 months)
+Relapse prevention planning

Recovery Timeline After Ibogaine Treatment

What published data tells us about outcomes at each time point.

24–48 Hours
Rapid resolution of acute withdrawal (25 of 33 within 24h — Alper 1999)

Ibogaine's direct opioid receptor action provides rapid withdrawal relief during the treatment session itself.

1 Week
Significant craving reduction; psychological clarity and motivation peak

The "afterglow" period where neuroplasticity is highest. Critical window for beginning integration work.

1 Month
50% opioid-free (Brown & Alper 2018); 88% PTSD symptom reduction (MISTIC)

Most published studies measure primary outcomes at this time point. Strong predictor of long-term success.

3 Months
No validated rate; aftercare quality becomes the dominant variable

The period where aftercare quality becomes the dominant variable. Environmental triggers re-emerge.

6 Months
No validated rate; improvements persist in published cohorts

No controlled 6-month abstinence data exists. Observational cohorts report sustained improvements in use and craving.

12 Months
Improvements sustained through 12 months in observational cohorts (Brown & Alper; Noller)

Long-term data is more limited. Patients with comprehensive aftercare significantly outperform those without.

24+ Months
No published data beyond 12 months

Very few studies follow patients beyond 12 months. Booster treatments may help those who relapse.

What Happens If Relapse Occurs?

Relapse after ibogaine treatment is not uncommon — a substantial share of patients experience some level of return to substance use within the first year (no validated percentage exists). However, ibogaine treatment differs from other approaches in several important ways:

  • —Relapse after ibogaine is often less severe — patients typically use less and recognize the pattern faster.
  • —The psychological insights from the ibogaine experience persist even through relapse, providing a foundation for recommitment.
  • —Booster treatments (a second ibogaine session 6–12 months later) are used by some clinics for patients who relapse; there is no published success-rate data for boosters.
  • —Some patients use low-dose ibogaine microdosing protocols to maintain benefits between full sessions.
  • —Relapse does not mean treatment failure — it is an opportunity to strengthen aftercare and address triggers that were missed.

Important Caveats

Research Limitations

  • —Most published studies are observational, not randomized controlled trials (RCTs).
  • —Sample sizes are generally small (30–200 participants), limiting statistical power.
  • —Significant self-selection bias: motivated patients tend to seek treatment and report outcomes.
  • —Follow-up periods vary widely; long-term data beyond 24 months is limited.
  • —Outcome definitions differ across studies, making direct comparisons difficult.

Individual Variation & Aftercare

  • —Success rates vary significantly based on substance type, duration of use, and co-occurring mental health conditions.
  • —Ibogaine is not a standalone cure — integration therapy and aftercare dramatically improve long-term outcomes.
  • —Genetics influence ibogaine metabolism; slow metabolizers face higher cardiac risk and require dose adjustment.
  • —Social support, environment, and post-treatment structure are critical predictors of sustained recovery.
