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, and form part of Drug Trends.

The aim of this bulletin is to describe engagement in various harm reduction behaviours on their last occasion of ecstasy and/or related drug use (e.g., LSD, ketamine, cocaine, methamphetamine) by a sample of people in Australia who regularly consume ecstasy and/or other illicit stimulants recruited from all Australian capital cities from April-July 2022.
