Ibogaine is a naturally occurring psychoactive indole alkaloid found in the root bark of Tabernanthe iboga and related plants. It can produce prolonged, dream-like psychoactive effects and is often described as a dissociative or psychedelic compound. A useful starting point is the broad overview of ibogaine’s chemistry and history, while its cultural context includes long-standing ceremonial use in Central and West African traditions, especially Bwiti-related practices.
Modern medical interest centers on opioid withdrawal interruption, craving reduction, and possible effects on PTSD, depression, traumatic brain injury, and other addiction-related conditions. That interest does not settle the question of effectiveness. The strongest point of agreement is that ibogaine carries serious cardiac risk, including QT prolongation and arrhythmia risk.
In the United States, ibogaine remains a Schedule I controlled substance. The DEA’s drug scheduling framework explains the federal category; research activity, public advocacy, and policy discussion do not make general use legal.
