Established in 1999, the Drug Use Monitoring in Australia (DUMA) program is funded by the Australian Government and is the nation’s longest-running ongoing survey of police detainees across the country. DUMA comprises two core components: a self-report survey on drug use, criminal justice history and demographic information; and voluntary urinalysis.

In 2019, 78 percent (n=676) of detainees tested positive to at least one type of drug, and 44 percent (n=382) tested positive to more than one drug type. Methamphetamine had the highest test positive rate of any drug (51%, n=444), and was also described as the most readily available.
