Is Ibogaine Safe? The Honest Answer

People have died from ibogaine.

We are going to start there, because you are going to find that out anyway, and we would rather you hear it from us than from a news story about a clinic that had no business treating anyone.

The honest answer to “is ibogaine safe” is: it carries a real risk that is largely specific, largely understood, and largely preventable — and whether it is safe for you personally depends almost entirely on two things. Your medical situation, and the standards of the place treating you.

This page explains what the risk actually is, what the deaths have had in common, who should never take ibogaine, and exactly what we do about it. It also tells you what to ask any clinic you are considering, including this one.

What the risk actually is

The primary danger from ibogaine is cardiac.

Ibogaine interferes with a potassium channel in heart muscle that helps control the electrical recovery between beats. Blocking it lengthens the interval known as QT. When the QT interval becomes long enough, the heart becomes vulnerable to a dangerous arrhythmia called torsades de pointes, which can be fatal.

Two features of this matter practically.

It is not brief. Ibogaine’s active metabolite, noribogaine, stays in the body far longer than ibogaine itself and has similar effects on cardiac conduction. QT prolongation can persist for days after the session, which is why the period after treatment requires monitoring just as much as the session does. A clinic that stops watching once you are awake has stopped watching too early.

It is measurable. QT can be seen on an EKG. It is affected by potassium and magnesium levels, both of which can be tested and corrected before dosing. Many of the conditions that make ibogaine dangerous are visible in advance to anyone who bothers to look.

Ibogaine also commonly slows heart rate during a session, and interacts with a long list of medications. Neither is exotic. Both are manageable when known about in advance.

What the numbers suggest

Historical estimates of ibogaine mortality vary enormously, largely because they mix together very different settings — supervised medical clinics, informal providers, and people dosing themselves at home.

The largest analysis to date, a June 2026 multisite study of 19,071 people across eleven international clinics operating under contemporary safety protocols, reported an overall mortality rate of 0.03%, or about 3 deaths per 10,000 people treated. Broken down by what people were treated for, the difference was stark: 6 deaths among 10,382 people treated for opioid use disorder (0.06%), and zero deaths among 8,689 people treated for non-substance-use indications.

An important caveat, and we would rather state it than bury it: that study is a preprint and has not yet been peer reviewed, and it draws on data reported by the clinics themselves. Treat it as the best available picture rather than a settled fact.

What it lines up with, though, is the pattern in the case literature going back decades — which is the part we find more useful than any single number.

What the deaths have had in common

When researchers have reviewed ibogaine fatalities, the same factors keep appearing:

Pre-existing heart disease. Frequently undiagnosed, because nobody screened.

Other drugs in the system. Polysubstance use at or around the time of death appears in a large share of cases. Opioids taken during or shortly after a session are a recurring theme, and fentanyl specifically featured in half the clinical deaths in the 2026 analysis.

Electrolyte problems. Low potassium and low magnesium both worsen QT prolongation. People arriving from months of poor nutrition, vomiting and dehydration are very often depleted in both — and both are correctable in a day.

Being dosed during active withdrawal or while medically unwell. Treating someone whose body is not ready is a decision, and it is the wrong one.

Little or no screening. In fatalities before 2016, limited pre-treatment cardiac evaluation is a repeated finding.

Read that list again and notice what it is. It is not a list of mysterious tragedies. It is a list of things a competent clinic checks for and refuses to proceed without.

That is the actual answer to whether ibogaine is safe. The molecule carries a specific, known cardiac risk. Nearly everything that has gone badly wrong has involved either an unscreened heart, an uncorrected electrolyte, another drug, or a clinic that treated someone it should have turned away.

Who should not take ibogaine

Some people are not candidates, and no amount of wanting it changes that. Absolute and relative contraindications include:

• Existing heart disease, arrhythmia, or a QT interval already prolonged on EKG
• A history of certain structural cardiac abnormalities
• Significant liver impairment, since ibogaine is metabolized by the liver
• Current use of medications that also prolong QT — this list is long and includes many antidepressants and antipsychotics, some antibiotics, and methadone itself
• Uncorrected low potassium or magnesium, until corrected
• Seizure disorders
• Active psychosis, or certain bipolar presentations
• Pregnancy
• Recent or ongoing use of other substances that have not been allowed to clear

Methadone deserves a specific mention, because it prolongs QT on its own. Someone arriving on methadone is carrying two QT-prolonging influences at once, which is one of several reasons people on methadone need a longer, more carefully managed lead-in than anyone else.

What we do about it

Every guest completes the following before ibogaine is even discussed as a date on a calendar:

• 12-lead EKG with QT interval measurement
• Complete blood work, including a metabolic panel and liver function
• Electrolyte testing, with potassium and magnesium corrected before any dosing
• Full medication review, including anything obtained informally
• Cardiac and medical history, with further cardiology assessment where indicated
• Psychiatric and psychological evaluation
• A managed washout period from other substances, of a length determined by what you have been taking

During the session itself, you are under continuous cardiac monitoring with medical staff present, and monitoring continues afterward for as long as your readings say it needs to — not until a scheduled discharge time.

Why we take longer than most

One of our founders arrived here for what was supposed to be a two-week program. It took a month before anyone would give him ibogaine at all, because his body was in no condition to receive it. Sleep, nutrition, bloodwork, and time — a month of it — before the treatment he had come for.

That is not a story we tell for atmosphere. It is the reason this clinic works the way it does.

A program built around a seven-day turnaround has only two options when someone arrives unfit for treatment: dose them anyway, or send them home. We have a third option, which is to take as long as it takes and then treat them properly. It costs us schedule and it costs us money, and it is the single most important safety decision we make.

Who we turn away

We refuse people. Not often, but it happens, and we think you should know the circumstances:

• Screening reveals a cardiac condition that makes the risk unacceptable
• A medication or drug interaction cannot be safely resolved
• Someone will not be honest about what they are taking
• Someone is not medically stable enough, and cannot be made stable enough within a reasonable stay
• Someone’s psychiatric presentation means ibogaine is the wrong intervention

If we screen you out, we tell you plainly, we explain why, and we help you find something more appropriate. Nobody is treated here because they have already paid.

A clinic that has never turned anyone away is not telling you it has good luck. It is telling you it does not screen.

The risk that comes afterward

There is a second danger that gets far less attention, and it is worth understanding before you commit to any program.

After treatment, your opioid tolerance is dramatically lower than it was. If someone relapses in the weeks following ibogaine — at whatever dose felt normal before — that dose is now capable of killing them. This is true after any detox, and it is one of the reasons the period after treatment matters as much as the treatment.

It is also part of why we do not run one-week programs. Sending someone home on day five, with tolerance at its lowest and cravings not yet settled, into the same house and the same phone contacts, is a medical decision as much as a clinical one.

What we cannot promise

We can reduce risk substantially. We cannot eliminate it.

Anyone who tells you their ibogaine treatment is completely safe, or guarantees your outcome, is either uninformed or lying, and either one should worry you. What a good clinic can honestly offer is thorough screening, real monitoring, the willingness to say no, and enough time to do it properly.

We also will not tell you ibogaine cures addiction. It doesn’t. It interrupts withdrawal and quiets cravings, and it opens a window in which real work becomes possible. What happens in that window is what determines the outcome.

Questions to ask any ibogaine clinic

Including us. If a clinic cannot answer these clearly, that is your answer.

1. What cardiac screening do you perform before treatment, and who reviews the results?
2. Do you test and correct potassium and magnesium before dosing?
3. What monitoring happens during the session, and for how long afterward?
4. Who is physically present during the session, and what are their qualifications?
5. What emergency equipment and medications are on site, and where is the nearest hospital?
6. How long is the washout period for what I am currently taking, and how do you decide?
7. Under what circumstances would you refuse to treat me?
8. Has anyone ever died at your facility?
9. What happens if I am screened out after I have paid?
10. What happens after the session, and how long do I stay?

That last pair matters more than people expect. A clinic that has thought carefully about refusal and about aftercare has thought carefully about everything else.

If you want to talk it through

If you are trying to work out whether ibogaine is safe for you specifically — or you are a family member trying to work out whether to support someone doing this — call us at (877) 876-4157.

We will ask about your medical history, your medications, and what you are actually taking. If the answer is that you are not a candidate, we will tell you, and it will not cost you anything to find out.

That conversation is free and confidential, and there is nothing to buy at the end of it.
