But addressing this crisis requires a multifaceted approach — and expanding access to naloxone is just one part of the solution. And while I urge people — particularly family members and friends of those with opioid use disorder — to develop at-home action plans, there’s a marked difference between responding to an unexpected emergency at home vs. what happens at a supervised injection site. For example, at home, the person doesn’t warn you that he or she is about to use and there is no access to clean needles or testing for the presence of fentanyl, a deadly synthetic opioid, in the drug before use. Instead, shame and fear of retribution keep this within the solitude of the bathroom or bedroom, usually behind a locked door.
