The Chicago Department of Public Health (CDPH) and the Chicago Public Library (CPL) have collaborated to make Narcan nasal spray available free of charge at all 81 CPL locations throughout the city in an expansion of efforts to prevent fatal opioid overdose. Narcan nasal spray is a medicine that can be used in emergencies to prevent fatal overdose, but it can be expensive and challenging to access. By making this medication freely available in public libraries, CDPH and CPL are lowering barriers to crucial harm reduction tools in every community area in the city. Overdose is one of the leading causes of the 10-year life expectancy gap between Black and white Chicagoans, a gap that widened during the pandemic.  In 2021, more than 1,420 people died of an opioid overdose in Chicago, the highest number ever recorded in the city.  CDPH and CPL piloted distribution of harm reduction kits in local libraries beginning in January, starting in libraries in communities with the highest numbers of opioid overdoses. Since then, CDPH has distributed over 2,000 Narcan kits and trained over 300 library staff on overdose prevention.  CDPH has trained more than 300 librarians, at least one at every branch, on opioid overdose prevention and how to use Narcan. The Narcan is available in small boxes on the wall at each library. Anyone can take Narcan from the box, no questions asked. However – if you do have questions, ask your local librarian.
