Expanded access to naloxone has been identified as a key intervention for reducing opioid related morbidity and mortality. It is not known which naloxone device will result in rapid, successful administration when administered by community members. The aims of this study were to estimate and compare 1) the rate of successful administration and 2) time to successful administration for single step nasal spray, multi‐step atomized nasal spray, and intramuscular simulated naloxone by community members.
