DASA: Cocaine in Australia - What Wastewater Tells Us

According to the most recent report from the National Wastewater Drug Monitoring Program (Report #19 released in July 2023), cocaine is the third most consumed illicit drug in Australia. Here is what wastewater data, collected in December 2022 and February 2023, tells us about our cocaine usage.

  • During COVID, from December 2020 to August 2022, cocaine consumption was on the decline, with record consumption lows recorded in both capital city and regional areas in August 2022.

  • However, cocaine consumption has since rebounded, with overall national consumption increasing between August and December 2022. Cocaine is now the third most consumed illicit drug in Australia (behind cannabis and methamphetamine).

  • Long term trends in cocaine usage clearly show consumption is much higher in capital cities than in regional areas.

  • NSW consistently records the highest cocaine usage across the country.

  • There is high variation in weekly consumption rates of cocaine, with higher consumption on weekends.

  • Australia ranked 18th of 27 Sewage Core Group Europe (SCORE) countries on cocaine consumption.
