This test proves we're using more meth
RESEARCH from the National Wastewater Drug Monitoring Program points to an increase in methylamphetamine consumption across Queensland.
Samples were collected from October to December 2017, covering 12 substances.
Forty-five waste water sites were monitored covering 54.3 percent of Australia's population - around 12.7 million people.
It estimates over 8.3 tonnes of methylamphetamine is consumed in Australia each year, as well as over 3 tonnes of cocaine, 1.2 tonnes of MDMA and 700 kilograms of heroin.
Nicotine and alcohol remain the highest consumed substances.
Queensland has the highest average use of MDMA, MDA and fentanyl.
The federal government will spend $3.6 million testing waste water to calculate drug use.
