A solid, readable textbook on the uses and importance of medical marijuana. Millions now treat their ills with medical cannabis or non-intoxicating cannabinoids like CBD. But lots of them don’t know why or how cannabis works in the body. 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. The book offers 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 to recount the story of the endocannabinoid system, its origins in the earliest forms of life on Earth, the evolution of its elements, and the discoveries, millions of years later, of more of its elements over time.  (Medium Discount)
