Addiction is increasingly being recognized as a major global public health issue, and an ever-growing number of medical specialties, psychological and social science training programs, and professional associations are including addiction as part of their training and continuing education curricula. The first edition of this book presented an overview of the spectrum of addiction-related problems across different cultures around the globe. Sharing the experience and wisdom of more than 260 leading experts in the field, and promoted by the International Society of Addiction Medicine, it compared and contrasted clinical practices in the field of addiction medicine on the basis of neurobiological similarities as well as epidemiological and socio-cultural differences. Building on the success of this inaugural edition, and taking into account the formal and informal comments received as well as an assessment of current need, this textbook presents general updated information while retaining the most requested sections of the first edition as demonstrated by the number of chapter downloads. It also provides a basic text for those preparing for the ISAM annual certification exam. Written by some 220 international experts, it is a valuable reference resource for anyone interested in medicine, psychology, nursing, and social science.
