In this extraordinary work, Beth Macy takes us into the epicenter of a national drama that has unfolded over two decades. From the labs and marketing departments of big pharma to local doctor's offices; wealthy suburbs to distressed small communities in Central Appalachia; from distant cities to once-idyllic farm towns; the spread of opioid addiction follows a tortuous trajectory that illustrates how this crisis has persisted for so long and become so firmly entrenched.
