Examining nonprescription syringe sales in Massachusetts and Rhode Island community pharmacies.

Background: The role pharmacies play in addressing the opioid crisis and drug-related risks such as injection drug use is evolving. Estimating the prevalence of injection drug use at the community level is challenging because of the stigma of drug use. Many community pharmacies sell nonprescription sterile syringes; thus, pharmacy-level sales of injection equipment may be an indicator of drug-related harms and unmet needs of high-risk populations.
