"When he signed up for a psychedelic retreat run by a mysterious Argentine woman deep in Brazil's rainforest in early 2018, Ernesto London?o, a veteran New York Times journalist, was so depressed he had come close to jumping off his terrace weeks earlier.His nine-day visit to Spirit Vine Ayahuasca Retreat Center included four nighttime ceremonies during which participants imbibed a vomit-inducing plant-based brew that contained DMT, a powerful mind-altering compound. The ayahuasca trips provided London?oan instant reprieve from his depression and became the genesis of his personal transformation that anchors this sweeping journalistic exploration of the booming field of medicinal psychedelics. London?o introduces readers to a dazzling array of psychedelic enthusiasts who are upending our understanding of trauma and healing. They include Indigenous elders who regard psychedelics as portals to the spirit world; religious leaders who use mind-bending substances as sacraments; war veterans suffering from PTSD who credit psychedelics with changing their lives; and clinicians trying to resurrect a promising field of medicine hastily abandoned in the 1970s as the United States declared a War on Drugs. London?o's riveting personal narrative pulls the reader through a deeply researched and brilliantly reported account of a game-changing industry on the rise. Trippy is the definitive book of psychedelics and mental health today and London?o's in-depth and nuanced look at this shifting landscape will be pivotal inguiding policymakers and readers as they make sense of the perils, limitations and promise of turning to psychedelics in the pursuit of healing"--
