"This is an exceptionally useful and well-timed book. I hope anyone concerned about this era's new addiction epidemic will read it and put its messages to use. Ben Westhoff very skillfully combines pharmacology, politics, law enforcement, and gripping international intrigue in his account of America's number-one public health problem. I hope Fentanyl, Inc. is widely read and influential."
-- James Fallows

"In Fentanyl, Inc., Ben Westhoff lays bare the twisted history that led to opioids wreaking havoc on twenty-first century America. If you want to understand the bloody cycle of addiction and death gripping the nation, you need to read this book."
-- JamIoan Grilloes, author of El Narco and Gangster Warlords
