Time is not a detail
A long session and a multi-hour ceremony are not interchangeable.
Reports of ibogaine often describe an extended acute period, sometimes followed by a prolonged reflective or residual phase. Ayahuasca ceremonies are often described as multi-hour events, sometimes with more than one serving or ceremony across a visit. Individual experiences vary substantially.
Ibogaine
Often discussed as a single, long acute session with effects and after-effects that may continue well beyond the most intense period.
Ayahuasca
Often organized as a multi-hour ceremony; the immediate experience can be repeated over more than one night in some settings.
Why it matters
Time course can shape what monitoring, transport, rest, medication review, and next-day planning may be relevant.
These broad patterns are not dosing instructions and should not be used to self-manage an experience. They are a reason to avoid treating two very different schedules as though they carried the same practical demands.
