This book presents a true history of the Sacred Mushroom throughout Mesoamerica, offering never-before seen details regarding colonial-era reports, including on the Aztecs, and includes sources on other indigenous cultures, like the Mazatec. It challenges the official narrative that the CIA was not involved in the creation of the psychedelic revolution and counterculture, providing recent discoveries that discount the official "blowback" narrative, and reveals how Gordon Wasson and others were less than honest in their presentations of the historical evidence. It discusses Aztec and Mesoamerican mushroom use and religious rites, including in human sacrifice and cannibalism.
