Dose-dependent effects vary significantly. Psychedelic experiences typically occur at 8–12 mg/kg; higher doses (15–25 mg/kg) produce more intense experiences and are used in addiction treatment settings. Individual sensitivity, body weight, gastrointestinal factors, and preparation purity affect onset and intensity.
Ibogaine has minimal abuse potential due to the typically unpleasant and challenging nature of the experience. The substance is actively being studied as a treatment for opioid and other substance use disorders rather than as a drug of abuse. Compulsive redosing is essentially unreported given the extreme duration and physically taxing effects.
Deaths have occurred with ibogaine use, particularly in individuals with cardiovascular disease, neurological disorders, or when combined with opioids. In clinical studies, one fatality occurred in a 24-year-old female who received approximately 29 mg/kg. Treatment in non-medical settings without expert supervision has been estimated to carry approximately a 1 in 300 risk of fatality.
Ibogaine causes long QT syndrome at higher doses, presenting serious cardiac risks that can be fatal; individuals with pre-existing cardiovascular conditions are at substantially elevated risk.
High-dose laboratory studies in rats showed degeneration of Purkinje cells in the cerebellum; however, subsequent primate studies and limited human research found no evidence of this neurotoxicity.
Manic episodes may occur and can last several days, potentially including insomnia, irritability, emotional instability, delusions, aggressive behavior, and thoughts of suicide. Depression is commonly reported following use and can persist well beyond 36 hours; in some cases, a persistently low mood may progress into major depressive disorder.
