The purpose of this study was to evaluate the extent to which demographic, sexual and non-injection drug use practices predict acoles cent initiation of injection drug use Methods. Streel recruited injection drug users 15-30 years of age in Balt more, Maryland who initiated injection within five years of study enro ment, completed a cuestionnaire that included a year-by-year story regarding the five years prior to initiation of injection. Factors associated with initiation during adolescence (21) were determined using logistic regression. Results. Of 226 participants, most were female (61%) and African American (64%). Median age of partic pants was 25 ; median age at initiation of injection was 23. Factors significantly associated with adolescent initiation in multivariate analysis included race other than African American, and practices prior to initiating injection including condom use, lack of cocaine use, exclusive crack smoking just prior to initiation, and smoking marijuanal Adolescent initiates also had shorter durations of illicit drug use prior to initiating injection Conclusion. Short-term non-injection drug use, particularly exclusive crack smoking, was associated with adoiescent initiation of injection drug use Early prevention efforts targeting this high-risk group of younger drug users are warrantecan order to delay or prevent onset of injection drug use.
