The Illicit Drug Reporting System (IDRS) is a national illicit drug monitoring system intended to identify emerging trends of local and national concern in illicit drug markets, and forms part of Drug Trends. The IDRS consists of annual interviews across all Australian jurisdictions with people who inject drugs (PWID), as well as analysis and examination of indicator data sources related to illicit drugs. The IDRS is designed to be sensitive to trends, providing data in a timely manner, rather than describing issues in detail. This report details findings from Brisbane and the Gold Coast, Queensland.

This includes:

  1. A report overviewing the key findings in 2020
  2. An infographic summarising key findings in 2020
  3. An executive summary of key findings in 2020

Results are not representative of all consumers or drug use in the general population and should be interpreted alongside findings from other data sources for a more complete profile of emerging trends in illicit drug use in Australia.
