[Risks incurred by the first intravenous drug injection].

Area of Science:

• Addiction research
• Public health
• Epidemiology

Background:

• Initiation into intravenous drug use (IDU) is a critical period for adopting risk behaviors.
• Understanding the social and situational context of first-time injection is crucial for harm reduction strategies.

Purpose of the Study:

• To describe the circumstances surrounding the initiation of intravenous drug use.
• To identify the role of the peer introducer in the first injection.
• To evaluate risk behaviors associated with the initial intravenous drug injection.

Main Methods:

• A cross-sectional survey was conducted in 1997 using a structured questionnaire.
• 143 intravenous drug users (IDUs) were interviewed in drug treatment centers and a prison in Paris.
• Data collected focused on the process of initiation into intravenous drug abuse.

Main Results:

• The mean age for first opiate use and first injection was 19 and 20 years, respectively.
• Heroin was the primary drug used (91%) during the first injection, often in the presence of others (91%).
• The introducer, typically an experienced IDU (93%) and often a friend (61%), prepared and administered the injection in most cases (72-74%).
• Borrowing injecting equipment was common (22%), with unknown HIV/HCV status of the source in over 80% of cases.

Conclusions:

• The peer introducer is pivotal in shaping risk behaviors during the first injection.
• Interventions targeting introducers can enhance education on safe injecting practices and promote harm reduction.
• Understanding the dynamics of first-time injection is essential for developing effective public health strategies for IDUs.
