While the use of mind-altering drugs is prohibited in many religions, other traditions around the world have long celebrated their spiritual and medicinal benefits. Entheogens used in a religious or spiritual context, include psychedelics such as peyote, psilocybin mushrooms, and ayahuasca, and the substances often supplement practices geared toward achieving transcendence. Further, many believe entheogens foster communication with the spirit world and help heal addiction, trauma, and depression. A growing interest in entheogens is evident in several books coming from religion and spirituality publishers in the coming year. Shamanic teachers Hank Wesselman and José Luis Stevens are among the authors coming out with new books. Check out a few titles that explore the intersection of drugs and spiritual development here.
