There is substantial contemporary interest in psychedelic agents as medicines for maladies of the mind. This follows research in the 1950s and 1960s exploring the use of LSD and other psychedelics to treat a range of psychiatric illnesses as well as addictions. Part of the Oxford Psychiatry Library series, this book by David Nutt and David Castle provides an overview of this hugely exciting field, covering the history of psychedelics, clinical aspects, risks and side effects, precautions, and processes.
