Davis et al. 2023: Open-Label Ibogaine + 5-MeO-DMT in Special Operations Veterans (n=86)

Definition

Definition: PTSD/trauma open-label series explicitly beyond Cherian MISTIC primary: Davis A.K., Xin Y., Sepeda N., & Averill L.A. (2023) *Open-label study of consecutive ibogaine and 5-MeO-DMT assisted-therapy for trauma-exposed male Special Operations Forces Veterans: prospective data from a clinical program (location named in the paper)*, *The American Journal of Drug and Alcohol Abuse* 49(5):587–596 (doi: 10.1080/00952990.2023.2220874). Prospective program-evaluation surveys at baseline and 1-, 3-, and 6-month follow-up in n=86 trauma-exposed male SOF veterans completing a clinic sequence of oral ibogaine then inhaled 5-MeO-DMT. Authors reported significant improvements in self-reported PTSD, depression, anxiety, insomnia, post-concussive symptoms, life satisfaction, psychological flexibility, and cognitive functioning from baseline to 1 month, with a signal of durability toward 6 months. This is combination sequential therapy, open-label, self-report-heavy—not MISTIC (oral ibogaine + IV Mg for TBI), not an RCT, not a cure claim, and not psychoactive IV ibogaine infusion proof. Builds on—but is distinct from—Davis 2020 retrospective survey (/blog/davis-2020-ibogaine-5meo-veterans). Ibogaine is Schedule I / not approved for any indication. QTc/cardiac risk remains central.

Short answer

Davis and colleagues’ 2023 American Journal of Drug and Alcohol Abuse prospective study of 86 SOF veterans found large self-reported PTSD and mood improvements after oral ibogaine then 5-MeO-DMT, with signals lasting toward six months. Open-label combination data are not MISTIC, not an RCT, and not psychoactive IV ibogaine infusion proof. Screen for QTc risk.

Why this paper matters

MISTIC dominates headlines, and Davis 2020 (/blog/davis-2020-ibogaine-5meo-veterans) was a retrospective survey. Readers still need a named non-MISTIC prospective PTSD/trauma study that refuses to merge oral combination protocols with Stanford oral+Mg TBI methods or with IV infusion claims.

What was studied

How it differs from MISTIC and from Davis 2020

Attribution rule: do not say “Stanford proved ibogaine+5-MeO cured PTSD” or “Davis 2023 is MISTIC.”

Key findings (no hype)

• Large pre→1-month improvements across trauma-relevant self-report scales (authors report significant p-values and effect-size statistics in-paper).
• Durability signal through 3–6 months for several domains—still open-label and attrition-sensitive.
• Combination therapy confounds attribution to ibogaine alone.
• Authors conclude potential for rapid robust change and call for controlled research.
• Psychological flexibility and acute meaningfulness themes appear in related predictor papers from the same program ecosystem—hypothesis-generating, not approved endpoints.

Honest reading: Important prospective real-world trauma signal in a highly selected male SOF sample; weak external validity for civilians; zero cure language.

Cardiac safety gap

Program-evaluation mental-health papers may under-detail continuous QTc tables. Ibogaine cardiac risk still applies (/blog/knuijver-2021-ibogaine-qtc-safety, /blog/ibogaine-qt-magnesium-protocol, /safety-and-screening). 5-MeO-DMT adds its own acute physiologic/psychiatric considerations—combination ≠ “safer because natural.”

Route honesty & entity clarity

Oral ibogaine (+ later 5-MeO) ≠ physician-supervised psychoactive IV ibogaine infusion. Supportive monitoring/IV fluids in clinic settings ≠ psychoactive IV ibogaine infusion (/blog/ibogaine-oral-vs-iv; /blog/ibogaine-vs-5-meo-dmt).

Limits and confounders

What this does NOT prove for IV ibogaine infusion

Civilian translation caution

SOF veterans in a structured abroad program are not the same population as civilian complex PTSD with untreated SUD, housing instability, or limited aftercare. Effect sizes in highly motivated, demographically narrow samples often shrink in broader care. For depression-adjacent reading see /ibogaine-for-depression—still without cure language.

Combination therapy: who gets the credit?

Allowed: “In Davis et al. 2023’s prospective open-label evaluation of consecutive oral ibogaine and 5-MeO-DMT among 86 SOF veterans, self-reported PTSD and related symptoms improved from baseline to one month with signals toward six months—findings that remain uncontrolled and not psychoactive IV ibogaine monotherapy proof.”

Forbidden: “Ibogaine cures veteran PTSD with 86-person science” or “same as Stanford MISTIC IV treatment.”

Related alcohol/PTSD comorbidity note

A related prospective analysis from overlapping SOF program data examined co-occurring risky alcohol use and PTSD symptom trajectories after the same combination approach (published open-access discussions cite large reductions in alcohol use intensity alongside trauma scores). That comorbidity signal reinforces “whole-person” aftercare needs—it still does not isolate ibogaine monotherapy or validate psychoactive IV infusion dosing.

One-sentence entity reminder

If a clinic quotes Davis 2023 while selling psychoactive IV ibogaine infusion, demand a route correction in writing—oral combination survey data do not transfer automatically.

FAQ

Which paper is this? Davis, Xin, Sepeda & Averill 2023, *Am J Drug Alcohol Abuse*, doi **10.1080/00952990.2023.2220874**.

Is it MISTIC? No. Different protocol family (ibogaine + 5-MeO; not oral+IV-Mg TBI primary).

Is it the 2020 Davis survey? No. This is prospective multi-month follow-up with larger n.

Was psychoactive IV ibogaine used? Not as psychoactive IV infusion—oral ibogaine then inhaled 5-MeO-DMT.

Is it an RCT? No. Open-label program evaluation.

Does this erase cardiac risk? No.

Is ibogaine approved for PTSD? No. Schedule I; not approved for any indication.

Where should screening start? /safety-and-screening → /apply.

Educational research synopsis only—not medical, psychiatric, or legal advice, and not a guarantee of PTSD outcomes. Ibogaine can prolong the QTc interval and has been associated with serious cardiac events including torsades de pointes and death in some contexts. Ibogaine is Schedule I in the United States and is not approved for any indication. Our IV ibogaine programs in Mexico and Gabon are not approved U.S. clinics.

Davis 2023 is an open-label combination oral-ibogaine + 5-MeO program evaluation—not a cure claim and not psychoactive IV ibogaine efficacy proof.
