Abstract
Since 1999, the AIC Drug Use Monitoring in Australia (DUMA) program has provided a unique and valued insight into trends in drug use and crime in Australia. Since its inception, 48,251 detainees have been interviewed across nine different police watch-house sites, with 35,277 also providing a urine sample for drug analysis. Findings include 24 percent of police detainees tested positive to amphetamines which constitutes an increase of eight percentage points since 2009–10 (16%). This is the highest recorded rate of amphetamine use since 2004, when it peaked at 34 percent.
