Ibogaine – Psychoactive effects
At doses of around 3–5 mg/kg of body weight, ibogaine has a mild stimulant effect. The high-dose ibogaine experience of 10 mg/kg or greater most commonly occurs as two distinct phases: the visual phase and the introspective phase
The visual phase is characterized by open-eye visuals, closed-eye visuals, and dreamlike sequences. Objects may be seen as distorted, projecting tracers, or having moving colors or textures. When the eyes are closed, extremely detailed and vivid geometric and fractal visions may be seen. Subjective reports often include a movie-like recollection of earlier life experiences as well as dreamlike sequences with symbolism of one’s present or anticipated future. Other effects in the visionary phase may include laughing, sensations of euphoria or fear, and temporary short-term memory impairment. The visionary phase usually ends after one to four hours, after which the introspective phase begins.
The introspective phase is typically reported to bring elevated mood, a sense of calm and euphoria, and a distinct intellectual and emotional clarity. Subjects often report being able to accomplish deep emotional and intellectual introspection into psychological and emotional concerns. It is also during this period that opioid addicts first notice the absence of withdrawal symptoms or cravings. The duration of the introspective phase is highly variable, usually lasting hours but sometimes lasting days.
