The data in this report were collected as part of the Australian Institute of Criminology’s Drug Use Monitoring in Australia (DUMA) program, which is a quarterly collection of criminal justice and drug use information from police detainees at multiple sites across Australia. From January 2015 to December 2016, 4,400 adult police detainees were interviewed in Brisbane, Adelaide, Perth and Sydney (Bankstown and Surry Hills), most of them male (83%; n=3,647). On average, recent users reported methamphetamine consumption 14 days out of the last 30 days before detention and rated the availability of methamphetamine on average at nine out of 10, while quality was given a rating of seven out of 10. A majority of recent users reported that the price of methamphetamine had not changed compared to the three months prior to interview, with a current price of approximately $50 per point.
