Abstract
Metabolic residue concentration data for two licit drugs (nicotine and alcohol), three medications of abuse (morphine, methadone and codeine) and six illicit drugs (cannabis, cocaine, amphetamine, methamphetamine, ecstasy and heroin) were obtained from raw wastewater samples collected from 44 Slovenian educational institutions are presented. Also, concentrations obtained at one secondary school during a preliminary study is provided. The wastewater samples were collected at the end of the 2018/2019 academic year using time proportional sampling and analysed for 16 drug residues, extracted using solid-phase extraction and analysed using ultra-performance liquid chromatography hyphenated to tandem mass spectrometry (UPLC-MS/MS). Residues of nicotine and alcohol were determined by direct injection of filtered wastewater onto the UPLC. Concentrations data were studied based on educational level (primary, secondary and tertiary) and institution type (secondary schools: gymnasiums, vocational and technical schools, multi-programme schools; higher education institutions: natural sciences and social sciences), geographic location (municipalities) and degree of urbanisation (urban and non-urban areas). Due to the large number of different educational institutions included in the study, provided datasets are valuable for further studies on drug consumption patterns among young people. Drug presence and prevalence data for primary schools (6-15 years) offer an objective insight into drugs present in the early stage of a young person's development and help establish effective prevention programs.
