Named a 2023 TOP BOOK ON CANNABIS by CBD Oracle 2020 GOLD MEDAL WINNER of the Nonfiction Book Awards (Nonfiction Authors Association) An Informative Read for an Audience Interested in Why and How Medical Cannabis Helps Treat a Range of Illnesses—Maybe All of Them With cannabis approved in fourteen states (including the District and two US territories), medical cannabis approved in at least 35 states, and hemp (very-low-THC cannabis) off the controlled substances list, 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. Healing with Cannabis explains the surprising reasons evolution conserved the endocannabinoid system over a billion years and tells specifically how cannabis has positive effects on some of society’s most devastating illnesses, including neurodegenerative diseases, post-traumatic stress disorder, pain, movement disorders, cancer and chemotherapy, and addiction. The book also shows how medical cannabis, widely available, will change the face of public health, and how nearly everyone can benefit from this versatile medicine that has a 5,000-year history of safe and effective use.
