The contemporary opioid crisis is widely seen as new and unprecedented. Not so. It is merely the latest in a long series of drug crises stretching back over a century. In  White Market Drugs,  David Herzberg explores these crises and the drugs that fueled them, from Bayer’s Heroin to Purdue’s OxyContin and all the drugs in between: barbiturate “goof balls,” amphetamine “thrill pills,” the “love drug” Quaalude, and more. As Herzberg argues, the vast majority of American experiences with drugs and addiction have taken place within what he calls “white markets,”  where legal drugs called medicines are sold to a largely white clientele. These markets are widely acknowledged but no one has explained how they became so central to the medical system in a nation famous for its “drug wars”—until now. Drawing from federal, state, industry, and medical archives alongside a wealth of published sources, Herzberg re-connects America’s divided drug history, telling the whole story for the first time. He reveals that the driving question for policymakers has never been how to prohibit the use of addictive drugs, but how to ensure their availability in medical contexts, where profitability often outweighs public safety. Access to white markets was thus a double-edged sword for socially privileged consumers, even as communities of color faced exclusion and punitive drug prohibition. To counter this no-win setup, Herzberg advocates for a consumer protection approach that robustly regulates all drug markets to minimize risks while maintaining safe, reliable access (and treatment) for people with addiction. Accomplishing this requires rethinking a drug/medicine divide born a century ago that, unlike most policies of that racially segregated era, has somehow survived relatively unscathed into the twenty-first century. By showing how the twenty-first-century opioid crisis is only the most recent in a long history of similar crises of addiction to pharmaceuticals, Herzberg forces us to rethink our most basic ideas about drug policy and addiction itself—ideas that have been failing us catastrophically for over a century.
