Harm reduction vending machines could improve access to health supplies for formerly homeless veterans in supportive housing, according to a study published in the Harm Reduction Journal. Researchers interviewed 44 veteran residents and 16 staff members across six San Francisco Bay Area housing buildings, finding that participants generally viewed the machines as a practical, accessible resource.

The interviews identified privacy, reliable stocking, program awareness and product selection as key considerations. Participants also reported fragile access cards, difficulty reaching retrieval bins and a need for multilingual instructions. Staff support, clear signs and residents sharing information with neighbors helped build awareness of the machines.

The authors recommended involving residents and staff in planning, establishing dependable maintenance routines and offering enrollment during regular housing activities. They also called for durable access methods and retrieval bins at waist height. The qualitative study examined implementation and participant perceptions rather than demonstrating reductions in overdoses or other health outcomes.
