Millions of us suffer from addiction, including psychiatrist and recovering alcoholic Carl Erik Fisher. But where does this centuries-old behaviour come from and how should we treat it?As a young doctor, Carl Erik Fisher came face to face with his own addiction crisis, one that nearly cost him everything. Now, in The Urge, he investigates the history of this condition; how we have struggled to define, treat, and control it; and how broader understanding and compassion could change people’s lives. The Urge is at once an eye-opening history of ideas, a riveting personal story of addiction and recovery, and a clinician’s urgent call for a more expansive, nuanced view of one of society’s most intractable challenges.
