Aims: Most people who inject drugs (PWID) were first initiated into injection by a current PWID. Few studies have examined PWID who assist others into drug injection. Our goal is to describe the prevalence of and risk factors for initiating someone into injection in the last 12 months.
Methods: We recruited a cross-sectional sample of PWID (N = 605) in California from 2011 to 2013. We examined bivariate and multivariate risk factors for initiating someone into injection with a focus on behaviors that might encourage injection initiation such as injecting in front of non-PWID, describing how to inject to non-PWID, and willingness to initiate someone into drug injection. Results: Having initiated someone into injection was reported by 34% of PWID overall and 7% in the last 12 months. Forty-four PWID had assisted 431 people into injection in the past year. Factors independently associated with initiating someone into injection in the last 12 months were self-reported likelihood of initiating someone in the future (Adjusted Odds Ratio [AOR] = 7.09; 95% Confidence Interval [CI] = 3.40, 14.79), having injected another PWID in past month (AOR = 4.05; 95% confidence interval [CI] = 1.94, 8.47), having described how to inject to non-injectors (2.61; 95% CI = 1.19, 5.71), and non-injection powder cocaine use in past month (AOR = 4.97; 95% CI = 2.08, 11.84) while controlling for study site. Conclusion: Active PWID are important in facilitating the process of drug injection uptake. Interventions to reduce initiation should include efforts to change behaviors and intentions among PWID that are associated with injection uptake among others. Highlights: This paper is the largest observational epidemiology study of PWID that initiate others into drug injection. There have been several editorials, reviews, and commentaries calling for more studies on injection initiation patterns and risk. This paper, with its robust findings, makes a very important contribution to the little studied behavior of initiating others into injection drug use. |
