The big question

Ibogaine: the most over-promised drug in addiction medicine, fact-checked.

Clinics quote trials that do not exist. The one rigorous human study has 30 people in it. At least 33 people have died, most in rooms with no cardiac monitor. Here is what the evidence actually supports, question by question, with every claim graded and cited.

After treatment

Does ibogaine show up on a drug test?

No. Ibogaine and its metabolite noribogaine are not included on standard workplace or clinical drug panels, so a routine 5, 10 or 12-panel test will not flag them.

The experience

How long does ibogaine last?

The acute experience lasts roughly 24 to 36 hours from a flood dose: an intense visionary phase of about 4 to 8 hours, then a longer reflective and physically depleted phase.

What happens after ibogaine? Aftercare and integration

Ibogaine is best understood as an interruption that opens a window of reduced craving, not a cure.

What is the ibogaine success rate?

There is no established success rate, because no controlled long-term trial has produced one.

Does ibogaine actually work?

It depends entirely on what "work" means. Ibogaine reliably interrupts acute opioid withdrawal in the cohorts studied, and shows early promise for PTSD and traumatic brain injury.

Safety

Is ibogaine safe?

Ibogaine is not casually safe. It has a real, well-established cardiac risk: it prolongs the QT interval and can trigger a potentially fatal arrhythmia.

How much does ibogaine treatment cost?

Is ibogaine legal?

In the United States ibogaine is a Schedule I controlled substance and is not legal for treatment in any state. In Mexico it is unscheduled, which is why clinics operate there openly.

Safety · read this first

One channel in the heart explains almost every death.

Ibogaine blocks the hERG potassium channel, stretching the heart's QT interval until, in the wrong patient, it tips into a fatal arrhythmia. Pre-existing heart disease, interacting medications and unmonitored rooms account for nearly all 33 reported deaths. Screening and monitoring are not amenities. They are the difference.

QT prolongation · the mechanism

A normal beat, then a stretched QT interval (red). Past a threshold, the rhythm can degrade into torsades de pointes. This is why an EKG before dosing is the floor, not a luxury.

Quick answers

the questions everyone asks first
Does ibogaine actually work?

For interrupting opioid withdrawal, yes, in the cohorts studied, and it shows early promise for PTSD and traumatic brain injury. It is not a proven cure for addiction, and for many conditions clinics advertise there is no human evidence at all. We grade each use separately.

Is ibogaine dangerous?

It carries a real, established cardiac risk. It prolongs the QT interval and can trigger a fatal arrhythmia, and at least 33 deaths appear in the literature, mostly in unscreened or unmonitored settings. Proper EKG screening and cardiac monitoring reduce that risk substantially but do not remove it.

Is ibogaine legal?

In the United States it is a Schedule I controlled substance and not legal for treatment in any state. In Mexico it is unscheduled, which is why clinics operate there openly. Recent US policy moves signal change but have not legalized it.

How much does ibogaine treatment cost?

Published prices in Mexico run from about $3,500 for short retreat programs to $30,000 for extended medical detox, with most 7-day detox programs between $7,500 and $15,500. It is private pay everywhere; no insurance covers it.

Can ibogaine detox you from benzodiazepines?

No, and it is dangerous to try. Ibogaine has essentially no effect on the GABA system, so it does not relieve benzodiazepine withdrawal, and benzodiazepines have been a factor in ibogaine deaths. Benzodiazepine dependence must be tapered off under medical supervision first.

Does ibogaine show up on a drug test?

No. Ibogaine and its metabolite noribogaine are not on standard 5, 10 or 12-panel drug tests. Only a specialized laboratory assay looking specifically for ibogaine can detect it.

Who should not take ibogaine?

People with heart disease or a prolonged QT interval, significant liver impairment, active psychosis or unstable bipolar disorder, anyone on QT-prolonging or interacting medications, and anyone dependent on benzodiazepines without tapering off first.

Do you take money from clinics?

No. This site sells no treatment and accepts no payment from clinics for coverage or placement. That independence is the whole point, and it is why we can grade honestly.
