An informative read for those interested in why and how medical cannabis helps treat a range of illnesses, maybe all of them. With an informal tone, a little humor, interviews with some of the most knowledgeable cannabinoid scientists, color images, and a selection of research and clinical trials, Healing with Cannabis informs readers about an ancient biological system newly discovered in every vertebrate on the planet, the endocannabinoid system. This system is the only reason cannabis works in the body, and it's why cannabis is effective in a broad range of disorders.
