The effect of a needle and syringe exchange on a methadone maintenance unit

In November 1986, a pilot needle and syringe exchange was established in Sydney adjacent to a methadone maintenance unit. A retrospective study was carried out to determine the effect of increasing the availability of sterile needles and syringes on the treatment outcome of the methadone maintenance unit. In this study, an increase in availability of sterile needles and syringes was not found to be associated with an increase in the presence of illicit injectable drugs in the urine specimens of clients of the methadone programme compared to a control methadone unit where there was no known change in needle and syringe availability. This study suggests that an increase in the availability of sterile needles and syringes does not appear to lead to an increase in the frequency of intravenous drug use. The possibility of drug and alcohol treatment centres acting as needle and syringe exchange or distribution outlets therefore requires consideration.
