Addiction is a preventable, treatable disease, not a moral failing. As with other illnesses, the approaches most likely to work are based on science — not on faith, tradition, contrition, or wishful thinking. SHeff has spent time with scores of scientists, doctors, counselors, and addicts and their families to learn how addiction works and what can effectively treat it. He offers clear, cogent counsel for parents and others who want to prevent drug problems and for addicts and their loved ones no matter what stage of the illness they’re in. But it is also a book for all of us — a powerful rethinking of the greatest public health challenge of our time.
