Needle and Syringe Programs and Bleach in Prisons: Reviewing the Evidence

A substantial amount of scientific evidence has shown that needle and syringe programs (NSPs) in the community are the most effective intervention available to prevent HIV transmission associated with injecting drug use. As well, NSPs have been associated with increases in access to care and treatment among people who use such programs, and with substantial cost-savings. The concerns raised about NSPs have been shown to be unfounded. NSPs have not led to increased levels of risk behaviour among people who use the programs or increased drug use by people who inject drugs.
