Psychedelics are big news. From micro-dosing to mushroom clinics to celebrity-endorsed ayahuasca retreats in Peru, they are moving ever more into mainstream consciousness. But psychedelics are also set to change the face of medicine, our treatment for mental health conditions like depression, and our understanding of the human brain. Rooted in his team's world-leading research in the brain imaging of psychedelics, as well as years of hands-on experience treating patients, in this book, Professor David Nutt will correct myths and misconceptions, equip us with the information to make informed decisions, and answer all your questions about this medical revolution.
