The Illicit Drug Reporting System (IDRS) is a national illicit drug monitoring system intended to serve as a strategic early warning system, identifying emerging trends of local and national concern in illicit drug markets. The IDRS consists of three components: interviews with people who inject drugs regularly (PWID); interviews with key experts (KEs), who are professionals who have knowledge of drug trends and/or regular contact with users through their work; and analysis and examination of indicator data sources related to illicit drugs.
The IDRS monitors the price, purity, availability and patterns of use of heroin, methamphetamine, cocaine and cannabis. The IDRS is designed to be sensitive to trends, providing data in a timely manner, rather than describing issues in detail. It is important to note that the information from the people who inject drugs (PWID) survey is not representative of illicit drug use in the general population and nor is the information representative of all illicit drug users, but is indicative of emerging trends that warrant further investigation. Drug trends in this publication are cited by jurisdiction, although they primarily represent trends in the capital city of each jurisdiction, in which new drug trends are likely to emerge.
