Established in 1999, the Drug Use Monitoring in Australia (DUMA) program is funded by the Australian Government and is the nation’s largest and longest-running ongoing survey of police detainees across the country. DUMA currently operates at five data collection sites and comprises two core components:

• a self-report survey including a range of criminal justice, demographic, drug use and drug market participation information; and
• voluntary urinalysis, which provides an objective measure for corroborating reported recent drug use (within 48 hours of arrest).

This biennial report is part of the Australian Institute of Criminology’s (AIC) Statistical Report series and aims to describe the DUMA data collected between January 2015 and December 2016 (herein referred to as 2015–16) at five sites: Adelaide (South Australia), Brisbane (Queensland), Perth (Western Australia) and Sydney (Bankstown and Surry Hills, New South Wales).
