"The data in this report offer no support for the idea that anti-OTC laws prevent illicit drug injection. However, the data do show associations between anti-OTC laws and HIV prevalence and incidence. In an ongoing epidemic of a fatal infectious disease, prudent public health policy suggests removing prescription requirements rather than awaiting definitive proof of causation. Such action has been taken by Connecticut, by Maine, and, recently, by New York. After Connecticut legalized OTC sales of syringes and the personal possession of syringes, syringe sharing by drug injectors decreased. Moreover, no evidence showed increased in drug use, drug-related arrests, or needlestick injuries to police officers."
