What Is Ibogaine? Uses, Risks and How It Works

Where ibogaine comes from

Ibogaine comes from Tabernanthe iboga, a shrub native to Central West Africa, including Gabon, Cameroon and the Republic of the Congo. The root bark has been used for generations in the Bwiti spiritual tradition in ceremonies of healing and initiation.

In the 1960s, American researcher Howard Lotsof reported that a single dose of ibogaine stopped his heroin cravings and withdrawal. That observation led to decades of interest in ibogaine as an addiction treatment.

What is ibogaine used for?

Today, ibogaine is most often used in clinics outside the US to:

Interrupt opioid withdrawal and reduce cravings, including for fentanyl, heroin and prescription opioids
Support people seeking to stop using stimulants or alcohol
Address PTSD, depression and traumatic brain injury, an area of growing research interest, especially among veterans
Support personal and spiritual exploration, often in retreat settings

Ibogaine is not a cure for addiction or mental health conditions, and it is not approved by the FDA for any use.

How does ibogaine work?

Researchers don’t fully understand it yet. Ibogaine acts on several brain systems at once, including opioid, serotonin and NMDA receptors. The liver converts it into a longer-lasting compound called noribogaine, which may explain why some people report reduced cravings for days or weeks afterwards.

What does ibogaine treatment involve?

In a responsible clinic, treatment happens under medical supervision. After screening, a person takes ibogaine and is monitored, including continuous heart monitoring, while the effects unfold. The acute experience commonly lasts a day or more and is often described as intense, dreamlike and introspective. Many people need several days of rest and observation afterwards.

What does the research say?

Most evidence comes from observational studies rather than large controlled trials. Results have been encouraging: a 2024 Stanford study of veterans with traumatic brain injury, treated with ibogaine plus magnesium, reported large reductions in PTSD, depression and anxiety symptoms. In 2025, Texas set aside about $50 million to fund ibogaine clinical trials. More rigorous research is still needed.

Is ibogaine safe?

Ibogaine has serious risks. It can disturb heart rhythm (QT prolongation), and deaths have been reported, usually where people were not properly screened or monitored. Risk increases with heart conditions, liver problems, low electrolytes and certain medications and substances.

Never take ibogaine on your own or from an unverified source. See the screening a safe provider requires.

Is ibogaine legal?
