Gatekeeping harm reduction in Canadian Federal Prisons: Perspectives on the threat risk assessment for the prison needle exchange program by prison administrative leadership

Addiction, EarlyView.
Abstract Background and aims Prison needle exchange programs (PNEPs) are evidence‐based, cost‐effective interventions that prevent transmission of blood‐borne viruses. PNEPs were introduced in a minority of Canadian federal prisons in 2018; however, participation is contingent on a mandatory approval process known as a “Threat Risk Assessment” (TRA ...
