Benzodiazepine use among injecting heroin users

OBJECTIVES: To determine the extent and patterns of benzodiazepine use among heroin users, and whether preferences for different benzodiazepines exist among this group. SUBJECTS AND METHODS: 210 heroin users who were current users of benzodiazepines volunteered for the study and completed a structured questionnaire. RESULTS: Heroin users had used a median of five different benzodiazepines, most commonly diazepam. Almost half the subjects (48%; 95% CI, 41-55) had injected benzodiazepines, 17% (95% CI, 12-22) within the preceding six months. Diazepam and temazepam were the most widely injected benzodiazepines. CONCLUSIONS: Flunitrazepam, diazepam and temazepam should be prescribed to heroin users with caution. A less popular and rarely injected benzodiazepine, nitrazepam, may be a better option for this group.
