One of the most common misconceptions about the opioid crisis is that it only affects people with a long history of drug abuse. Today, more than ever, a more diverse population is affected, potentially due to illicit fentanyl on the black market. In this ACT ToxChats© podcast, joined by Dr. Richard C. Dart of the Rocky Mountain Poison and Drug Safety, Denver Health and Hospital Authority, we discuss the history of opioid abuse, the factors that might have contributed to the current crisis, and other drugs that have played a role. We also discuss ways pharmaceutical and regulatory toxicologists may intervene.
