Poly-drug use associates with a range of acute and chronic health problems, but the understanding of their association with risk behaviors in low- and middle-income countries remains limited. The objective of this study was to understand the prevalence of different poly-drug clusters among a cross-sectional sample of 509 people who inject drugs (PWIDs) in Hanoi, Vietnam, and their sociodemographic and behavioral correlates, utilizing latent class analysis (LCA). LCA identified three distinct substance use classes including (1) low opioids and alcohol use, (2) moderate use of opioids, alcohol, and tobacco, and (3) high and poly use of substances. High levels of substance use were strongly associated with being male, older than 35, unemployed, not living with Hepatitis C individuals, no history of being arrested, and currently not involved in methadone treatment. Individuals in the high and poly-drug use group were also more likely to be involved in unsafe sex and injection behaviors, which are significantly delayed for low and moderate drug users. These findings illustrate the pronounced prevalence of poly-substance use among PWIDs in Vietnam and demonstrate the need for the better epidemiological understanding of the complexity of substance use patterns among high-risk populations
