In its 16th year, the Illicit Drug Data Report 2017–18 (IDDR) provides an authoritative picture of illicit drugs in Australia. It continues to inform policy and operational decisions across government, industry and the not-for-profit sector and focuses efforts to reduce the impact of illicit drugs on our communities.
In 2017–18, there were 112,827 drug seizures and 148,373 illicit drug arrests. 30.6 tonnes of illicit drugs were seized nationally with methylamphetamine remaining one of the most consumed and seized illicit drugs in Australia.
The report provides an overview of changes since the previous reporting period and also includes longer term trends in key market indicators—including border detections, national seizures and arrests, price, purity, forensic analysis, wastewater analysis and drug user survey data—which inform and enhance our understanding of Australia’s illicit drug markets and the ability to identify changes within them.
