Giving away used injection equipment: missed prevention message?

Area of Science:

• Public Health
• Epidemiology
• Addiction Science

Background:

• Injection drug use (IDU) is associated with significant health risks, including viral transmission through shared equipment.
• Understanding the patterns and correlates of injection equipment sharing is crucial for developing effective harm reduction strategies.

Purpose of the Study:

• To investigate factors associated with the distributive sharing of injection equipment among IDUs.
• To evaluate the role of needle exchange programs (NEPs) in mitigating this sharing behavior.

Main Methods:

• A cross-sectional survey was conducted with 145 Canadian IDUs aged 16+ who had injected in the past 30 days.
• Data collected included socio-demographics, HIV risk behaviors, social support, and NEP use.
• Bivariate statistics and logistic regression analyses were employed to identify correlates of sharing.

Main Results:

• Distributive sharing was most common for cookers (45%), followed by needles (36%), water (36%), filters (29%), and swabs (8%).
• Factors associated with sharing varied by equipment type, including history of crack/cocaine injection, mental health problems (ASI score), age, gender, methadone/stimulant use, homelessness, and HCV status.

Conclusions:

• Cooker sharing is more prevalent than needle sharing among IDUs, with distinct correlates for different equipment types.
• Sharing behaviors are linked to marginalized IDUs, emphasizing the need for targeted interventions, especially for cooker sharing, to reduce disease transmission.
