Book excerpt: A sweeping and highly readable work on the evolution of America’s domestic and global drug war How can the United States chart a path forward in the war on drugs? In Drugs and Thugs, Russell Crandall uncovers the full history of this war that has lasted more than a century. As a scholar and a high-level national security advisor to both the George W. Bush and Obama administrations, he provides an essential view of the economic, political, and human impacts of U.S. drug policies. Backed by extensive research, lucid and unbiased analysis of policy, and his own personal experiences, Crandall takes readers from Afghanistan to Colombia, to Peru and Mexico, to Miami International Airport and the border crossing between El Paso and Juarez to trace the complex social networks that make up the drug trade and drug consumption. Through historically driven stories, Crandall reveals how the war on drugs has evolved to address mass incarceration, the opioid epidemic, the legalization and medical use of marijuana, and America’s shifting foreign policy.
