We studied needle sharing among intravenous drug users in New Orleans, where needles are not controlled by prescription. Three hundred and eighty self-identified intravenous drug users were interviewed regarding needle-sharing practices, frequency of drug use, and drug(s) of choice. Overall, 65.8% admitted they regularly used needles which had been used by others. No significant differences in needle sharing were found by sex, race, frequency of injection, or drug of choice. A survey of pharmacies found that 85.5% have self-imposed restrictions on the sale of needles and syringes. Legal availability of injection equipment may not be equivalent to actual availability to the consumer.
