We assessed pharmacists' practices for needle and syringe (NS) sales and their attitudes toward a needle exchange program through a telephone survey of 75 randomly selected pharmacies in Baltimore, Maryland, where possession of drug paraphernalia is illegal but where NS can be purchased without a prescription. Pharmacists' (n=46) procedures for NS sales included asking for picture identification (54%), requiring a prescription (34%), or requiring a diabetic identification (DID, 34%) for NS purchase; multiple responses were allowed. The median number of prescription and nonprescription NS sold per month was 950. Most (86.6%) pharmacists reported selling NS without prescriptions at their discretion. Pharmacists sold a median of 16 nonprescription NS per month. Pharmacists who required prescriptions or DID (56.5%) sold nonprescription NS significantly less often than those who did not require prescriptions or DID (p=.007). Most pharmacists (87%) were aware of the needle exchange program, 78.3% supported the program, and 67.4% supported selling nonprescription NS in pharmacies. Although there was no difference in anticipated effects of needle exchange or in support for needle exchange between pharmacists who did or did not require prescriptions, DID, or both, pharmacists who did require these items were significantly less likely to support pharmacy sales of nonprescription NS than pharmacists with less restrictive sales policies (p=.04). Although most pharmacists surveyed supported access to sterile NS by injection drug users through a needle exchange program, there was a diversity of approaches to nonprescription NS sales among pharmacists in a city that does not require prescriptions for access to sterile NS. Most supported nonpharmacy needle exchange programs, and more than one half limited injection drug users' access to NS through restrictive sales practices. To reduce injection drug users' exposure to HIV, pharmacists should be educated about HIV prevention and injection drug use and be included in development of HIV prevention programs, including legal pharmacy NS sales.
