This accessible text provides trainee human service providers and those currently working in the field with a comprehensive, cutting-edge overview of topics related to the medical and therapeutic use of cannabis. Employing an interdisciplinary, biopsychosocial framework, the book explores the different biological, cultural, and policy contexts of medical cannabis from a wide range of perspectives including practitioners, academics, and medical cannabis advocates. This book bridges the gap between theory and practice and underscores the urgent need for expanded and rigorous scientific research as medical cannabis is increasingly legalized, that may result in new cannabis-based medicines and help in identifying what health risks cannabis use may present. Chapters are both evidence-based and practical, weaving in learning objectives, review questions, and varied case examples, all of which will prepare students and professionals for the reality of working with medical cannabis consumers.
