Three groups of injecting drug-users were defined in terms of their experience of methadone treatment: treatment for periods longer than 6 months, treatment for shorter periods, and no treatment. Methadone treatment and the use of needle exchanges were related in subsequent analysis to the sharing of injecting equipment. Comparisons between groups were made on other variables believed to be associated with sharing. Significant differences were observed between treatment groups in the recency of sharing and in the use of needle-exchanges. Age and length of drug use were important factors in sharing, which was least prevalent among older respondents in long-term treatment. Regular use of needle-exchanges was associated with the passing on of used equipment to others. Subsequent analysis of regular users suggested respondents in long-term treatment were less likely to pass on their equipment than those in the other two groups.
