This Q&A about Szalavitz’s forthcoming book, "Undoing Drugs: The Untold Story of Harm Reduction and the Future of Addiction" (Hachette Books, 2021), will explore the history of harm reduction and what it suggests about dealing with the current overdose crisis. It will examine the false narrative that now drives opioid policy and how harm reduction offers both a more accurate and a more effective way to manage drug issues.
