Formatted Abstract/Summary
Introduction and Aims: Wastewater analysis has become a useful technique for monitoring illicit drug use in communities. Findings have been reported from different countries in Europe and North America. We applied this technique to gauge the illicit drug consumption in an urban catchment from South East Queensland, Australia.
Design and Methods: The sampling campaigns were conducted in 2009 (21st November–2nd December) and 2010 (19th–25th November). We collected daily composite wastewater samples from the inlet of the sewage treatment plant using continuous flow-proportional sampling. Ten illicit drug residues (parent compounds and keymetabolites) in the samples were measured using liquid chromatography coupled to tandem mass spectrometer.
Results: Seven compounds were quantified in all the samples. Our data indicated higher drug consumption on weekends. Cannabis was the highest used drug in both sampling periods. Compared to the first sampling campaign which indicated that cocaine and methamphetamine use exceeded ecstasy usage, the second sampling
campaign suggested the use of methamphetamine exceeded that of ecstasy which in turn exceeded cocaine use.
Discussion and Conclusions: The observed weekly trend of drug use in our study is in agreement with findings in other studies. The variation between two sampling periods in the prevalence of drug use may relate to the availability and prices of the drugs on markets. The cocaine use we estimated in 2009 was much greater than estimations
obtained through the national household survey [1], implying underreporting of cocaine use in surveys. Future work is underway to tackle methodological challenges for more accurate estimation.
