Early The use of psilocybin mushrooms by humans in religious ceremonies dating back thousands of years is contested. Despite popular narratives portraying psychedelics as ancient, widespread, and primarily used by
shamans for therapeutic healing, careful anthropological and historical research shows their traditional use was limited, recent, and culturally specific, with modern Western interpretations largely shaped by idealization, tourism, and ideological agendas. 6,000-year-old
pictographs discovered near the Spanish town of
Villar del Humo illustrate several mushrooms that have been argued to be
Psilocybe hispanica, a hallucinogenic species native to the area. Some scholars have also interpreted archaeological
artifacts from
Mexico and the so-called
Mayan "mushroom stones" of
Guatemala as evidence of ritual and ceremonial use of psychoactive mushrooms in the
Mayan and
Aztec cultures of
Mesoamerica. The
hallucinogenic species of the
Psilocybe genus have a history of use among the native peoples of
Mesoamerica for religious communion, divination, and healing, from
pre-Columbian times to the present day. Aztecs and
Mazatecs referred to psilocybin mushrooms as genius mushrooms, divinatory mushrooms, and wondrous mushrooms when translated into English.
Bernardino de Sahagún reported the ritualistic use of
teonanácatl by the Aztecs when he traveled to Central America after the expedition of
Hernán Cortés. The Spanish believed the mushroom allowed the Aztecs and others to communicate with demons. Despite this history, the use of
teonanácatl has persisted in some remote areas. Anecdotal reports suggests the mushroom was used spiritually and traditionally by
Basotho healers, marking it the only documented instance of traditional hallucinogenic mushroom use in Africa and the earliest recorded reference to such practices in Sub-Saharan Africa. This experiment reviewed the subjects six months later, and found that the recidivism rate had decreased beyond their expectation, below 40%. This, and another experiment administering psilocybin to graduate divinity students, showed controversy. Shortly after Leary and Alpert were dismissed from their jobs by Harvard in 1963, they turned their attention toward promoting the
psychedelic experience to the nascent
hippie counterculture. ==Society and culture==
