Tripping the Trail of Ghosts: Psychedelics and the Afterlife Journey in Native American Mound Cultures by P. D. Newman

P. D. Newman investigates spiritual journeys in Mississippian mound cultures in Tripping the Trail of Ghosts. The Path of Souls, sacred-plant traditions and the symbolism of earthworks form the center of his exploration.

Newman compares these beliefs with other afterlife texts and proposes interpretations of ritual evidence. Readers should distinguish those reconstructions from settled archaeological consensus; the book's accounts of psychoactive plants are not safe-use instructions.
