Published by the Comprehensive Opioid, Stimulant, and Substance Use Program (COSSUP), this publication provides details about training content surrounding overdose response for officers; how agencies obtain their naloxone; and respondents’ beliefs on whether administering naloxone and other programs aimed at reducing opioid use in the community is a responsibility of law enforcement agencies. This data was formulated based on the 2020 Law Enforcement Overdose Response Survey fielded by RTI International to a nationally representative sample of law enforcement agencies, including municipal police departments, county sheriffs’ offices and state police. Agencies participating in the survey differed in rurality and size, thereby providing a comprehensive view of how diverse law enforcement agencies across the country have equipped their officers to respond to illicit drug use in their communities.
