The Ecstasy and Related Drugs Reporting System (EDRS) is an illicit drug monitoring system which has been conducted in all states and territories of Australia since 2003, and forms part of Drug Trends. The EDRS consists of annual interviews across all Australian jurisdictions with people who regularly use ecstasy and other stimulant drugs, as well as analysis and examination of indicator data sources related to illicit drugs. This report details findings from Perth, Western Australia.
