METHAMPHETAMINE residue has been found in wastewater of an Australian coastal city at levels almost 5 times what they were in 2009, suggesting a corresponding increase in methamphetamine use, according to a Short Report published today in the Medical Journal of Australia. Researchers from the University of Queensland and the Queensland University of Technology used liquid chromatography and mass spectrometry to analyse 498 wastewater samples drawn from a coastal metropolitan city in south-east Queensland between 2009 and 2015, and 712 samples from a major inland regional city (2010-2015). “Methamphetamine consumption (measured in mg per day per 1000 inhabitants) was higher in the metropolitan city than in the regional city, and levels in both locations increased significantly between 2009–2010 and 2015. “Consumption increased 4.8 times in the metropolitan area between 2009 and 2015, and 3.4 times in the regional city between 2010 and 2015,” the researchers wrote. “Our data do not allow us to decide whether methamphetamine consumption has increased because there are more new users, because current users are consuming higher doses of a purer drug, or as a result of a combination of these possibilities.” The study, the authors wrote, showed the value of wastewater analysis for providing timely data on trends in illicit drug…
