A report released by The Australian Institute of Criminology, "Drug Use Amongst Police Detainees: Some Comparative Data", shows higher levels of opiates amongst people recently detained by police in Australian and English sites than in USA sites. Drug Use Monitoring in Australia (DUMA) program is part of the International Arrestee Abuse Monitoring Program (IADAM), in which detainees are interviewed about their drug and crime history and then asked to provide a urine sample. The study monitors trends in illicit drug usage and provides information on the correlation between drugs and crime.
