Empire of Pain: The Secret History of the Sackler Family by Patrick Radden Keefe:
African Americans had been spared the full brunt of the opioid epidemic: doctors were less likely to prescribe opioid painkillers to Black patients, either because they did not trust them to take the drugs responsibly or because they were less likely to feel empathy for these patients and want to treat their pain aggressively. As a result, levels of addiction and death were statistically low among African Americans. It appeared to be a rare instance in which systemic racism could be said to have protected the community. But people of color were disproportionately affected by the war on drugs. Purdue executives might have evaded jail time for their role in a scheme that generated billions of dollars for Madeleine’s family, but in 2016, Indiana’s governor, Mike Pence, signed a law reinstating a mandatory minimum sentence for any street-level dealer who was caught selling heroin and had a prior conviction: ten years. Nationwide, 82 percent of those charged with heroin trafficking were Black or Latino.
