The use of drugs of abuse is a concern for social and public health aspects, but also for environmental contamination. However, the study of these pollutants becomes important since the magnitude, nature and consumption patterns can be evaluated through the range of compounds detected in wastewater treatment plant (WWTP). Wastewater based epidemiology depend on the principle that traces of compounds, which a population is exposed to or consume are excreted unchanged or as metabolites in urine and/or faeces, and ultimately end up in the sewer network. For this purpose, it was used a high-performance liquid chromatography - tandem mass spectrometry (HPLC-MS/MS) analytical method to assess the concentrations of two drug of abuses and metabolites (cocaine and cannabis) in influent samples from Penha and Ilha do Governador WWTPs, in the Municipality of Rio de Janeiro. A systematic use of cocaine and cannabis was identified by detection in all samples analysed. This study corroborates with other findings related to the methodological approach which can be largely applied to monitor the use of drug of abuses, giving important subsidies to both environmental and health control systems.
