"Within three hours after ingesting a higher dose of ibogaine, the user will enter into the 'acute phase,' typically lasting four to eight hours.42 It is during this phase that the user experiences ibogaine’s most intense effects, characterized as the 'panoramic recall of a large amount of material relating to prior life events from long-term memory, primarily in the visual modality,' or the 'waking dream' state.43 If the user is an addict, he or she will usually be taken back to the place and time where the underlying issue leading to the addiction arose, allowing the addict to gain critical insight into the reasons why he or she abuses."
