Even after a decades-long opioid overdose crisis, intense controversy still rages over the fundamental nature of addiction and the best way to treat it. With uncommon empathy and erudition, Carl Erik Fisher draws on his own experience as a clinician, researcher, and alcoholic in recovery as he traces the history of a phenomenon that, centuries on, we hardly appear closer to understanding-let alone addressing effectively. A rich, sweeping account that probes not only medicine and science but also literature, religion, philosophy, and public policy, The Urge illuminates the extent to which the story of addiction has persistently reflected broader questions of what it means to be human and care for one another. Only by reckoning with our history of addiction, Fisher argues, can we light the way forward for those whose lives remain threatened by its hold.
