Chasing the Scream By Johann Hari BLOOMSBURY The drug war is viewed by many as a 40-year-old waste of resources. But in this beautifully written book, British journo Johann Hari shows that its roots extend as far back as the early 1900s, when young Harry Anslinger heard the shrieks of a neighbor in withdrawal; he grew up to lead the Bureau of Narcotics, the DEA's precursor, pioneering ruthless drug policies that endured for decades.
