The US is actively advancing government-funded clinical trials of ibogaine, a psychedelic drug that remains classified as a Schedule I controlled substance and has been linked to several dangerous health effects, including irregular heart rhythm. The Food and Drug Administration (FDA) is now seeking public input on how early-stage clinical trials of ibogaine should be designed, including dosing, patient selection, and safety monitoring. The move comes after President Donald Trump signed an executive order in April, directing federal agencies to accelerate research into psychedelic drugs for serious mental health conditions. The federal government has allocated $50 million for ibogaine research. The first government-funded trials will focus on adults with opioid use disorder (OUD) and post-traumatic stress disorder (PTSD). The research is being supported by the Advanced Research Projects Agency for Health (ARPA-H) and the National Institute on Drug Abuse (NIDA).

It has sparked interests of scientists and researchers as it is reported to reduce drug cravings and alleviate symptoms of withdrawal. In a nutshell, it has shown benefit in people with opioid and other substance-use disorders. Unlike existing addiction treatments, ibogaine can produce a prolonged psychedelic experience and affects several neurological systems. Researchers are investigating whether these effects could help alter brain circuits related to addiction and reduce substance use. But it must be noted that plenty of this evidence comes from observational studies, open-label research, and small clinical trials. Therefore the FDA is trying to ramp up more evidence rather than introducing the drug directly into widespread medical use.

Excessive prolonged QT can trigger dangerous ventricular arrhythmias, including Torsades de Pointes, which can prove to be fatal. Although considered rare, a 2026 review published in Addiction found that these cardiac events have occurred at therapeutic doses and even in people without known heart disease. Ibogaine could also lead to neurological toxicity. Reuters reported that FDA officials have highlighted both dangerous heart arrhythmias and brain toxicity as risks that need to be better investigated and understood before the drug can be developed more safely. Why US Is Accelerating Research Despite The Risks? The FDA's recent request seeks input on dose escalation, clinical settings, cardiac and neurological monitoring, eligibility criteria, stopping rules and independent safety. A proposed starting dose for early-phase studies would not exceed 10 mg/kg. The agency has also said that people with serious conditions that have not responded to existing treatments deserve rigorous investigation of new options. “Patients facing serious conditions that have not responded to existing treatments deserve rigorous scientific investigation of promising new approaches,” said Michael Davis, MD, PhD, director of the FDA's Center for Drug Evaluation and Research. “With ibogaine, there are important scientific questions as well as serious safety concerns. We are seeking high-quality data and input that can help inform clinical research while putting patient safety first.” Ibogaine's Schedule I classification means that under the US federal law it is considered to be most likely be used for abuse and it cannot be currently accepted for medical use.Items under this category carry extensive restrictions on possession and research. But Schedule I classification does not mean a substance can never be studied. Rather, research of such compounds require regulatory controls and approvals. The FDA has already allowed an early-stage study of noribogaine hydrochloride, which is a desrivative of ibogaine, for alcohol use disorder. It means that the regulator is actively seeking to study psychedelic drugs that could have medicinal potential.
