A sample of 312 heroin users were interviewed regarding their benzodia
zepine use. The majority (94%) had used benzodiazepines, 72% in the 6
months prior to interview. Benzodiazepine injecting was common, with 2
8% of the sample having injected these drugs, 13% in the 6 months prec
eding interview. Current benzodiazepine injectors showed greater polyd
rug use, injection-related HIV risk-taking behaviour, criminal involve
ment, psychological distress and injection-related health problems, as
well as poorer general health, and an increased risk of having overdo
sed than other users of benzodiazepines. Of those subjects who had inj
ected benzodiazepines, 55% were no longer current benzodiazepine injec
tors. Concern for general health emerged as the most common reason for
having made a transition away from injecting, and for being likely to
make such a transition.
