All opioid overdose related deaths can be prevented with the timely delivery of Naloxone. This study is a one-time, preliminary survey of participants with opioid use disorder to assess the need for, and community attitudes towards, a wearable device capable of autonomously detecting and responding to an opioid overdose. The results of this survey will be used to guide ongoing development of a de novo device. This study will be conducted over a 3 month period and survey participants from the Kensington Neighborhood in North Philadelphia.
