“Naloxone access may unintentionally increase opioid abuse through two channels: (1) saving the lives of active drug users, who survive to continue abusing opioids, and (2) reducing the risk of death per use, thereby making riskier opioid use more appealing,” the University of Virginia’s Jennifer Doleac and the University of Wisconsin’s Anita Mukherjee write. Because there are more opioid abusers needing to fund their drug habit, theft may also rise.
