The eighth report from the National Wastewater Drug Monitoring Program (NWDMP) was released. The study examines wastewater from sewage treatment plants in both capital cities and regional areas to estimate drug usage across the country. Methylamphetamine had the highest dose levels of all the illicits included in the report but it is important to note that comparisons on consumption of different drugs in this report is based on “doses consumed rather than drug mass”. This study does not look at prevalence. The high levels of methylamphetamine found could be due to a larger number of people using small amounts, or a relatively small number of people using larger amounts of the drug.
