I just added Empire of Pain: The Secret History of the Sackler Dynasty by: Patrick Radden Keefe to the Recommended Reading List.
This is a 30,000 foot view of the opioid crisis in America centered around the family most responsible for it. Radden combines the factual accuracy of a Jane Mayer, colorful antidotes and an almost Erik Larson ability to make non-fiction read like a compelling novel.
Combined with Beth Macy’s Dopesick this book will give you sufficient information on the opioid crisis.
