Russia has experienced a large increase in injecting drug use since the col
lapse of the Soviet Union. Injecting drug use is presently attributed with
up to 90 perccent of newly acquired HIV. Peer educators of an outreach prog
ram conducted a survey of injecting drug users (IDUs) in Moscow. The survey
was supplemented by qualitative field notes. Due to differences in setting
s and methods, the hospital and street survey results are presented separat
ely. A total of 298 hospital and 126 street surveys were collected. Results
showed that IDUs are young (average 20 years), and the majority were study
ing or working. Needles were rated as easy to get, although police pressure
often deters carrying a syringe. Sharing needles was common; IDUs that use
d only heroin were significantly less likely to share (RR 0.38 to a. 56). I
DUs that had spoken to a peer educator were also less likely to share (RR 0
.55). Heroin users had lower rates of hepatitis. Self-assessed HIV risk was
unclear for many IDUs. HIV prevalence was 3 percent.
