If you’re looking for ibogaine clinical trials to sign up for, you picked a good week to start. On October 5, 2026, the FDA formally asked the public for input on how early ibogaine trials should be designed. That’s the federal government doing its homework before ibogaine studies get going in the US, and it’s one more sign that this medicine is finally being taken seriously.
Here’s the catch, though, and we’d rather tell you now than let you find out the hard way: almost nobody can join an ibogaine trial today. Most of the big US programs are still being set up, and when they open, they’ll take a small number of carefully chosen people.
So this guide covers both sides. First, which ibogaine clinical trials are coming and how to get your name in. Second, what you can actually do this year if you can’t wait.
The short answer: Several state-funded ibogaine clinical trials are being organized in the US, led by Texas, but most aren’t enrolling yet. You can watch ClinicalTrials.gov and the university research teams involved, and talk to your doctor. Trials take small numbers of people with specific diagnoses, though. If you need help now, most Americans get medically supervised ibogaine treatment in Mexico instead.
Which Ibogaine Clinical Trials Are Happening in 2026?
A few years ago, this section would have been one sentence long. Now it’s a list, and that’s genuinely exciting.
Texas (the big one). In December 2025, Texas awarded $50 million to a team led by UTHealth Houston and UTMB Health to run a two-year, multi-site ibogaine research program across 11 Texas institutions. The work covers addiction, plus traumatic brain injury, with a focus on veterans.
Arizona. Arizona put $5 million into an ibogaine trial at Barrow Neurological Institute in Phoenix, with first participants hoped for in 2027.
Mississippi, Tennessee and Kentucky. All three passed laws in 2026 to fund or authorize ibogaine research. Mississippi’s law ties its program to the lead consortium in another state, which in practice means working alongside Texas.
Colorado. Colorado lawmakers voted in May 2026 to create an ibogaine research pilot program with up to five research sites, including heart screening and medical oversight.
Federal research. The April 2026 executive order put $50 million in federal money toward matching state research. According to the FDA, federal health agencies are prioritizing two groups for ibogaine research: adults with opioid use disorder and adults with PTSD. The FDA has also cleared an early-phase study of noribogaine, a compound the body makes from ibogaine, for alcohol use disorder.

How to Sign Up for an Ibogaine Clinical Trial
There’s no single sign-up list for ibogaine clinical trials. Instead, here’s how to give yourself the best shot:
- Search ClinicalTrials.gov. This is the official US registry. Search for “ibogaine” (and “noribogaine”), then filter by “Recruiting” or “Not yet recruiting.” Each listing shows who’s eligible and who to contact.
- Watch the university teams. Keep an eye on news from UTHealth Houston, UTMB Health and Barrow Neurological Institute. Trials usually announce enrollment through the institution running them.
- Talk to your doctor. Some trials take referrals from physicians, and your doctor can help you read the eligibility rules honestly.
- Get your records together. Trials ask detailed questions about your health, your heart, your medications and your substance use. Having that ready helps.
- Be wary of anyone charging you. Clinical trials generally don’t charge participants to take part. If a “trial” wants a deposit, it isn’t a trial.
Who Actually Gets Into an Ibogaine Trial?
This is the part that surprises people. Clinical trials aren’t designed to help as many people as possible; they’re designed to answer a research question cleanly. As a result, the rules are strict.
Every trial sets its own criteria, but expect things like these:
- A specific diagnosis. Many will focus on opioid use disorder or PTSD, and some on brain injury in veterans.
- A healthy heart. Ibogaine affects heart rhythm, so heart conditions and some medications will rule people out.
- Limits on other drugs and medications. Using several substances, or taking certain prescriptions, can disqualify you.
- Living nearby and showing up. Trials often need repeat visits for months, so location matters.
- No guarantees. In some study designs, part of the group gets a comparison treatment instead of ibogaine.
None of that is a reason not to apply. It’s just worth knowing that even a well-qualified person may wait a long time, or not get in at all.
Trials Are Research, Not Treatment
We’re thrilled these trials are happening. They’re how ibogaine eventually becomes a legal, prescribed medicine in the US, and that would change everything. Still, it’s important to see them for what they are. A trial serves the research first and the participant second.
If you’re dealing with fentanyl, methadone, alcohol or years of trauma right now, waiting for a slot that may open in 2027, may not fit you and may not even include ibogaine for your group is a lot to ask. That’s not a criticism of the research. It’s simply the reality that trials and treatment are two different things.
What to Do While You Wait
Most Americans who want ibogaine now go to Mexico, where it isn’t prohibited and where clinics have offered it for decades. Notably, the Stanford study of 30 special operations veterans that helped spark this whole wave of research followed veterans who were treated at a clinic in Mexico. Our guide to where to get ibogaine treatment walks through every option.
If you go that route, choose a clinic that runs things the way a good trial would: real medical screening, a doctor on site and heart monitoring. Here’s how we do it at Freedom Ibogaine, our ibogaine clinic in Rosarito, Mexico:
- A heart and blood check first. You get an EKG and full blood work, and our doctor reviews every medication before approving a dose.
- A switch when it’s needed. Fentanyl, methadone, Suboxone and kratom have to clear first, so a supervised switch adds days at the start.
- One supervised flood dose. Most guests have it on day two or three of the stay. A doctor and a nurse are there for the whole session, watching your heart rhythm.
- A short stay. The core program is seven nights with meals and 24/7 care, a short drive from San Diego. We arrange your ride from there.

The Future Is Coming. You Don’t Have to Wait for It.
Honestly, it’s an incredible time to be in this field. The FDA is asking how to run ibogaine trials. States that rarely agree on anything are funding them. Veterans are testifying about what ibogaine did for them. Within a few years, there may be real, published, controlled results from American universities.
If you can wait for that, apply to every trial you qualify for. If you can’t, you have options today. Either way, apply online or call us at (619) 485-0198, and we’ll talk through what makes sense for you, even if the answer is “try for a trial first.”
Ibogaine Clinical Trials: Common Questions
Are there ibogaine clinical trials in the US right now?
They’re being set up. Texas, Arizona, Mississippi, Tennessee, Kentucky and Colorado have funded or authorized research, and the FDA has cleared an early-phase noribogaine study. Most programs aren’t openly enrolling yet, so check ClinicalTrials.gov for current status.
How do I sign up for an ibogaine clinical trial?
Search “ibogaine” on ClinicalTrials.gov, filter for recruiting studies, and contact the listed study team. Also follow the universities running state programs, such as UTHealth Houston, UTMB Health and Barrow Neurological Institute.
Do ibogaine clinical trials cost anything?
Legitimate clinical trials generally don’t charge participants. Some even cover travel or pay for your time. Be cautious of any “trial” that asks you for money.
Are there ibogaine clinical trials near me?
Probably not yet, unless you live near one of the research centers. Trials usually need you to attend in person, so check each listing’s locations on ClinicalTrials.gov.
When will ibogaine be approved?
Not for several years. A drug has to pass Phase 1, 2 and 3 trials before the FDA can approve it, and ibogaine is at the very start of that process in the US.
What can I do if I don’t qualify for a trial?
Many people choose medically supervised ibogaine treatment in Mexico. Look for heart screening, a doctor on site and continuous monitoring, whoever you choose.
