There are few first-hand reports of drinking ayahuasca by residents of Amazonia, where use is widespread. One of us (F.A.F. ), who lives in Iquitos, took ayahuasca 30 times during a three-year period between 1972 and 1974 in an attempt to experience all levels of hallucination. Although unable to achieve the ultimate goal of telepathy and extrasensory perception, this author clearly relates his repeated experiences within the three other levels of hallucination and also correlates these experiences with those of others he observed who drank ayahuasca at the same time.
