In October 1993, the Maine legislature repealed the prescription law regulating the sale of syringes. The new law allowed but did not require licensed pharmacists to dispense syringes without a prescription to anyone 18 years of age or older. From November 1995 to January 1996, we conducted a telephone survey of 208 Maine pharmacists to evaluate the sale of syringes with and without a prescription and to assess pharmacists' willingness to sell syringes without a prescription. We found that 94% of pharmacists were willing, in all cases or at the discretion of the pharmacist, to sell syringes without a prescription. However, when asked specifically about willingness to sell syringes without a prescription to suspected injection drug users (IDUs) > or =18 years of age, 47% were willing, 40% were not willing, and 13% did not know or declined to answer. Pharmacists reported other requirements for the purchase of syringes without a prescription, such as the requirement for the customer to provide a reasonable justification for the purchase. In all, there were 31 (15%) pharmacists in the sample willing to sell syringes to without a prescription with no additional requirements for purchase to suspected IDUs as permitted by law. There were few negative incidents reported involving IDUs and the sale of syringes without a prescription since amendment of the law. Although sales of syringes without a prescription were reported, the numbers sold fell short of the estimated number of syringes required for IDUs in Maine to use a new syringe for every injection. Despite the change in the prescription law intended to increase access to syringes, the data suggest barriers such as drug paraphernalia laws and pharmacy policies may prevent IDUs from purchasing syringes and contribute to ongoing transmission of HIV. Amendment of the drug paraphernalia and syringe possession laws, clarification of the legitimate medical purpose of access to sterile syringes for IDUs, and offering pharmacists continuing education on the prevention of blood-borne disease appear to be necessary steps in the effort to decrease the transmission of HIV among IDUs in Maine.
