Continuing drug risk behaviour: Shared use of injecting paraphernalia among London heroin injectors

Abstract

The study investigates donor sharing and recipient sharing of different types of injecting equipment and the frequency of sharing activities with sexual partners, close friends and casual acquaintances. Structured interviews were conducted with 303 injectors recruited as part of a study of early and episodic opiate use. Subjects were contacted in non-clinical, community settings by a peer recruitment method (Privileged Access Interviews). Spoons and water containers were more frequently shared than needles and syringes. Significant differences were obtained between the frequency of sharing different types of injecting equipment. Many injectors had shared spoons or water containers, but had not shared needles or syringes. Frequency of sharing with others was also associated with intimacy of relationship to the subject. Almost two-thirds of the sample had shared some sort of injecting equipment during the previous year. The sharing of injecting paraphernalia presents a risk of infection with HIV , hepatitis B and hepatitis C. Injectors and drug workers should be more clearly aware of the risks involved in such activities. Harm reduction advice given to drug injectors should target the sharing of injecting paraphernalia. Research into sharing should explicitly include questions about the use of different types of injecting equipment.
