Free psychedelic books and essays on therapy, culture, ethnobotany, mystical experience, and psychedelic exploration

MAPS provides a collection of psychedelic books and essays available to read or download online for free, with additional titles offered through the MAPS Store. The resources cover the history and therapeutic use of LSD, including clinical procedures, psychotherapy, personal recollections, and Albert Hofmann's reflections on sacred drugs, mysticism, and science. Other works examine entheogens, perceptual diversity, psychedelic drugs and mystical consciousness, ayahuasca ethnopharmacology and ritual use in Santo Daime, Secoya traditions, and sacred mushroom studies. The collection also includes broader accounts of psychedelic experience, such as Aldous Huxley's writings, research into the Eleusinian mysteries, Myron Stolaroff's decades of exploration, and reports of MDMA and other empathogenic experiences. The page functions as a curated access point rather than presenting new analysis or recommendations.
