The Ecstasy and Related Drugs Reporting System (EDRS) is a national drug monitoring system intended to identify emerging trends of local and national concern in illicit drug markets. It forms part of Drug Trends.

Australian population data and data from the EDRS suggest an increase in cocaine use. This bulletin aims to investigate past months of cocaine consumption and associated behaviours (i.e., overdose, bingeing, driving under the influence of cocaine) amongst EDRS participants in Canberra, ACT, from 2003 to 2021.
