Dr. Gregory Smith, author of the best selling textbook on Medical Cannabis, delivers a patient focused and scientifically supported book, for people that want to learn the truth about CBD. He delivers what hasn't been available in 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 exciting by intermingling science with personal stories from his practice over the past two decades. The book is conveniently divided into three sections: the history and legal issues surrounding CBD and cannabis, how it works in the body and brain, and the final section is a series of short chapters providing sound advice on how to use CBD for 17 conditions including chronic pain, tapering off opioids, fibromyalgia, anxiety and seizures. In this interactive book about CBD and its effects, Dr. Smith provides many links to resources and articles to learn more. Unlike the other much shorter CBD and cannabis books on the market, Dr. Smith’s "CBD: What You Need to Know" is a complete overview of CBD and how to use it, making CBD an available treatment option for you and your loved ones today.
