A cross-sectional study on prevalence of non-fatal drug overdose and associated risk characteristics among out-of-treatment injecting drug users in North Vietnam.

In a community-based cross-sectional survey among out-of-treatment male opiate injecting drug users (IDU) aged 18-45, data on non-fatal overdose were collected using a semi-structured questionnaire. From August to September 2003, 299 IDU were recruited in two districts of Bac Ninh, a semi-urban province in North Vietnam. Prevalence of lifetime and recent non-fatal overdose were 43.
