Dr Iker Puente´s book Psychedelic psychotherapy and research. Past, present and future is a comprehensive guide to the work that is currently being done in this field, collecting the contributions of numerous leading researchers and psychotherapists, as well as documenting the work carried out during the 1960s and 1970s by a series of pioneer researchers, including Stanislav Grof, James Fadiman, Claudio Naranjo, William Richards and David Nichols. This book includes a total of 16 interviews and dialogues conducted over seven years in different countries, places and circumstances.This work is being published with very appropriate timing. It is being presented to the scientific and professional community and lay audiences at a time when we are experiencing a remarkable worldwide renaissance of interest in scientific research of psychedelic substances. This is an unexpected and surprising change after four decades during which official legally sanctioned clinical work was made almost impossible by very restrictive legislation responding to mass unsupervised use of these substances. These developments engender hopes that in the future psychedelics will return to the hands of therapists and responsible experimenters.Dr. Iker Puente's book reviews the research carried out in the 1960s and 1970s, the motives behind the restrictive legislation that made official legally sanctioned clinical work almost impossible for decades, and the remarkable worldwide renaissance of interest in scientific research of psychedelic substances we are experiencing at present. For several years the author has been interviewing the researchers, psychiatrists and psychologists who have studied and are currently studying the potential of these substances for the treatment of different psychological and emotional disorders, for creativity and problem solving and to induce mystical experiences, among other uses.The book describes in detail the present situation of psychedelic research, and points to the future of this flourishing and promising field of study. The rich and complete information contained in this book will be most beneficial for the future of psychedelic research and psychotherapy, describing in clear and articulate language everything that is necessary to know about this field to the professional community and lay audiences alike. “Dr. Puente’s interviews with seminal contributors to the renaissance in psychedelic research constitute a treasure trove, reflecting the past, present and potential future of this incredible frontier of knowledge and treatment”. William A Richards, PhD author of Sacred Knowledge, Psychedelics and Religious Experiences. “As the field of psychedelic psychotherapy becomes more mainstream, the wisdom of the pioneers interviewed by Dr. Puente becomes ever more important to reflect upon, especially as commercial for-profit investors seek monetary gain more so than conscious evolution. Dr. Puente asks excellent questions to his interviewees making this an important book coming out at a crucial time”. Rick Doblin, PhD Founder and director of the Multidisciplinary Association for Psychedelic Studies. “This delightful book is comprised of interviews with fifteen of the people who have been significantly involved in psychedelic research (plus one interview with an anonymous underground therapist). The interviews provide interesting back story and insight into when, why, and how the interviewees entered this important and rapidly growing field, deepening our understanding of their main contributions and future projects. It is a priceless documentation of some of the history of the renewal of research on psychedelics”.David Nichols, PhD, President of the Heffter Research Institute
