New psychoactive substances are produced and marketed to mimic the effects of their illicit counterparts and to attempt to evade drug tests and prosecution. Here, we present the optimisation, validation and application of an analytical method using liquid chromatography-time-of-flight mass spectrometry to detect and quantify 37 new psychoactive substances and illicit substances in wastewater from South Wales, UK, using a targeted analysis method. Sample preparation was performed using solid-phase extraction with Oasis HLB cartridges. The LC separation was performed using a YMC-Triart Phenyl 450 bar column (12 nm, 5 μm, 100 × 3 mm) which provided good separation and resolution for all targeted analytes with a run time of 9 min. The method was validated using the following parameters: sensitivity, selectivity, linearity, accuracy, precision, recovery and matrix effects. The method was then applied to influent wastewater samples collected from two wastewater treatment plants in Wales, UK.

Nowadays, synthetic cathinones (SCs) is the second more representative subclass of New Psychoactive Substances, accounting for 104 analogues in the illegal market. Since its first report in 2011, α-pyrrolidinovalerophenone (α-PVP) gained popularity among drug users, provoking an increased number of intoxications. Nonetheless, pharmacokinetics data is still limited in the literature.

Motor vehicle accidents (MVA) are the leading cause of death in childhood and young adult age. One of the most important factors behind MVA is driving under the influence of alcohol (DUIA) and drugs (DUID). The importance of DUID is rising together with the increasing drug abuse.

Cannabis derivatives are among the most widely used psychoactive substances in the world, which leads to growing medical concerns regarding its chronic use and abuse especially among adolescents. Exposure to THC during formative years produces long-term behavioral alterations that share similarities with symptoms of psychiatric and neurodevelopmental disorders. In this study, we have analyzed the functional and molecular mechanisms that might underlie these alterations.

3-Chloromethcathinone (3-CMC) is a synthetic cathinone that has been identified as a new psychoactive substance (NPS) by the European Monitoring Centre for Drugs and Drug Addiction. Despite its increasing prevalence in the recreational drug market since 2014, scientific literature on 3-CMC remains limited. This study employed a multi-step approach to investigate 3-CMC metabolism.

Novel psychoactive substances (NPS) have historically been difficult compounds to analyze in forensic toxicology. The identification, detection and quantitation of these analytes and their metabolites has been difficult due to their rapid emergence, short life span and various potencies. Advancements in analytical instrumentation are fundamental to mitigating these NPS challenges by providing reliable identification and sensitivity.
