Participants either or more vulnerable (e.g., often homeless) likely to report risky poor health outcomes than those also live close reporting Conclusions The marginalized are most at risk harms related injecting drug therefore need service. determine long-term impact on key such as overdose, future studies should consider vulnerability behavior when examining facility.
