Dr. Gregory Smith, author of the best-selling textbook on Medical Cannabis, delivers a patient-focused and scientifically supported book for people who want to learn the truth about CBD. He delivers what hasn't been available from other books by providing the education and information needed to be able to select a high-quality CBD medication from the sea of poor-quality products currently available. Dr. Smith keeps this book relevant by intermingling science with personal stories from his practice over the past two decades. The book is conveniently divided into several sections covering an overview of the history and legal issues surrounding CBD and cannabis, how it works in the body and brain, and how it can be used to effectively treat a variety of both mental and physical conditions, including chronic pain, addiction, anxiety, fibromyalgia, neurodegenerative diseases, and more. In this interactive book about CBD and its effects, Dr. Smith provides many links to resources and articles to learn more. Unlike the other CBD and cannabis books on the market, Dr. Smith's "CBD: What You Need to Know" is a comprehensive overview of CBD and how to use it, making CBD a viable treatment option for you and your loved ones today.
