Why the numbers vary
Success depends on what you count (no use at all, reduced use, no withdrawal at the end of treatment, a better mood score), when you count it (the day you leave, a month later, a year later), and who you count (everyone who came, or only the people who answered the phone). A center that measures withdrawal relief at discharge will report above 80 percent. A center that measures total abstinence at one year, in everyone, will report far less. Both can be honest. Ask which one you are hearing.
What the studies found
- Opioid withdrawal. The best documented effect. Brown and Alper (2018) followed thirty people treated in Mexico: withdrawal symptoms resolved in most, and about a third reported no opioid use at twelve months. A New Zealand series by Noller and colleagues (2018) followed fourteen people for a year and found large, sustained reductions in use. Davis and colleagues (2017) surveyed 88 people: 80 percent said ibogaine drastically reduced or eliminated withdrawal, 30 percent reported never using again, and 41 percent reported relapse followed by reduced use.
- Alcohol and stimulants. Observational reports of reduced craving and periods of abstinence, no controlled trials. Relapse is common without follow-up.
- PTSD, depression, anxiety. The 2024 Nature Medicine study on thirty special operations veterans found average reductions of more than 80 percent in disability scores and large drops in PTSD, depression and anxiety at one month, with benefits persisting in follow-up. It was an open-label study without a placebo group.
- What is missing. No large randomized controlled trial has been completed for any indication. The signal is consistent and strong; the proof, in the regulatory sense, is not there yet.

What "success" looks like in practice
For dependence: getting through withdrawal without agony, then a window of weeks in which craving is absent or faint, then the work of rebuilding a life so that the window becomes a life. Relapse in that period is common and is not the end; it is a reason to call. For trauma, burnout and grief: a night that shows the material with distance, followed by months in which sleep, mood and reactivity measurably improve for most, and the changes people make with that clarity.
How Bwiti Life measures
We measure before and after: sleep, heart-rate variability, resting heart rate and other markers from wearables and bloodwork, and validated questionnaires for mood, anxiety and craving. We follow every guest for three months, and we tell you what we see. We do not publish a headline percentage, because we would have to pick which one, and the honest ones make bad marketing. Ask us on the discovery call and we will show you the data we have.
How to read a provider's claim
Ask what was counted, when, and in whom. Ask whether people who did not answer follow-up are in the denominator. Ask whether they follow anyone at all. A provider quoting 90 percent without a definition is quoting withdrawal relief at discharge, or quoting nothing.
Questions people ask
What is the success rate at Bwiti Life?
We do not publish a single number. We measure sleep, heart-rate variability, mood, anxiety and craving before and after, follow every guest for three months, and share the results with each guest and, in aggregate, on request.
Is one treatment enough?
For many, one retreat and three months of follow-up produce the change they came for. Some return a year or more later for a different question. Repeated flood doses close together are not how the medicine is used.
Does the tradition change the outcome?
We think the container, the life review and the days of processing change what people do with the experience, which is what determines the outcome. It has not been measured in a trial; it is what our guests tell us, and what we see in the follow-up.
Why do people relapse after ibogaine?
Because the medicine interrupts the dependence and does not change the life around it. The people, places and stresses that drove the use are waiting at home. That is what the three months after are for.
