*CBD: An Essential Medicine* is a photographic documentary and historical examination of the people, patients, advocates, and policy developments that helped transform cannabidiol (CBD) from an overlooked component of cannabis into an internationally recognized medicine.

Through original photography, firsthand accounts, historical documentation, and policy analysis, photographer and veteran advocate Mike Davis traces the modern CBD movement from California's pioneering medical cannabis community to contemporary debates within international drug policy. The book documents patients, cultivators, researchers, advocates, and organizations whose work challenged decades of conventional thinking about cannabis and medicine.

Moving between personal stories and international policy, *CBD: An Essential Medicine* examines the development of CBD-rich cannabis, the experiences of patients who helped bring CBD into public consciousness, and the continuing effort to establish evidence-based cannabis policy within the United States and international institutions.

Part photographic history and part policy document, the book preserves an important chapter in the history of medical cannabis while asking a larger question: Has the evidence reached the point where CBD and cannabis medicines deserve recognition as essential medicines?
