This is the eighth in a series of National Wastewater Drug Monitoring Program reports to be publicly released by the Australian Criminal Intelligence Commission.

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.

This seventh report covers 54 per cent of the population, which equates to about 12.6 million people. Fifty wastewater treatment plants across Australia participated in the December 2018 collection, which monitored the consumption of 13 substances.

For this sixth report, wastewater samples were collected during weeks of June and August 2018. Wastewater analysis was conducted at 58 sites (22 capital city and 36 regional) across all Australian states and territories, covering 13 substances, providing a detailed picture of national drug consumption.

The Australian Criminal Intelligence Commission has released the fifth report of the National Wastewater Drug Monitoring Program. In addition to reporting on national drug consumption, this report includes updated SCORE data which provides international consumption comparisons for a number of drugs monitored by the program.
