The Chemical Carousel: What Science Tells Us About Beating Addiction by Dirk Hanson is an in-depth look at addiction science and medical treatments for drug dependence and alcoholism. An experienced science and business journalist, author Hanson brings a complex and widely misunderstood subject out of the shadows and into the light of understanding. In this groundbreaking and highly readable examination of addiction science and the biological, emotional, and scientific underpinnings of substance abuse, The Chemical Carousel breaks through the myths, while presenting the surprising and cutting-edge facts about addiction and its medical origins. Hanson leaves no stone unturned in this invaluable examination of why people become addicted. This is not a textbook or scientific paper, however. Rather, The Chemical Carousel is a book for the rest of us: friends and families of addicts, support groups, and healthcare professionals alike.
