“…However, comprehensive HRMS-based screening and confirmatory methods for NPS hair analysis are reported to a limited number of studies, mainly because they need standardized spectral libraries for screening and identification of compounds present in a sample [ 23 , 30 , 38 ]. Some attempts [ 23 , 86 ] succeeded to construct MS/MS spectral libraries including large numbers of NPS and metabolites. Initially, Montesano and colleagues described the development of a broad screening technique for NPS that included the use of an in-house MS/MS spectral library for 300 NPS and known metabolites [ 23 ].…”

“…Initially, Montesano and colleagues described the development of a broad screening technique for NPS that included the use of an in-house MS/MS spectral library for 300 NPS and known metabolites [ 23 ]. More recently, the development of a comprehensive compound database for 875 unique chemical entities considered as possible NPS, in addition to a full HRMS MS/MS spectral library for 252 of these compounds was reported [ 86 ].…”

“…These techniques can allow for sampling across a range of biological samples, including blood, urine, hair, 223 saliva, 224 urban wastewater and dried blood samples. 225,226 Samples for analysis require laboratory pre-preparation before being used for these techniques, though so-called 'dilute and shoot' techniques are being validated to allow for more rapid preparation of biological samples for liquid chromatography mass spectrometry. 227,228 Liquid chromatography with quadrupole time of flight mass spectrometry (LC-QTOF MS) has demonstrated some superiority to gas chromatography mass spectroscopy (GC MS) in detecting most forms of NPS within serum samples.…”

New psychoactive substances (NPS) are a heterogeneous group of substances. They are associated with a number of health and social harms on an individual and societal level. NPS toxicity and dependence syndromes are recognised in primary care, emergency departments, psychiatric inpatient and community care settings. One pragmatic classification system is to divide NPS into one of four groups: synthetic stimulants, synthetic cannabinoids, synthetic hallucinogens and synthetic depressants (which include synthetic opioids and benzodiazepines). We review these four classes of NPS, including their chemical structures, mechanism of action, modes of use, intended intoxicant effects, and their associated physical and mental health harms. The current challenges faced by laboratory testing for NPS are also explored, in the context of the diverse range of NPS currently available, rate of production and emergence of new substances, the different formulations, and methods of acquisition and distribution.

“…The HighResNPS library currently has active users from more than 10 laboratories around the world with the intention to ensure up-to-date analytical information from the moment a specific NPS becomes available to a given participating laboratory [102]. These libraries are available to help and facilitate the screening of NPS and their metabolites [101,[104][105][106].…”

New psychoactive substances (NPS), often designed as (legal) substitutes to conventional illicit drugs, are constantly emerging in the drug market and being commercialized in different ways and forms. Their use continues to cause public health problems and is therefore of major concern in many countries. Monitoring NPS use, however, is arduous and different sources of information are required to get more insight of the prevalence and diffusion of NPS use. The determination of NPS in pooled urine and wastewater has shown great potential, adding a different and complementary light on this issue. However, it also presents analytical challenges and limitations that must be taken into account such as the complexity of the matrices, the high sensitivity and selectivity required in the analytical methods as a consequence of the low analyte concentrations as well as the rapid transience of NPS on the drug market creating a scenario with constantly moving analytical targets. Analytical investigation of NPS in pooled urine and wastewater is based on liquid chromatography hyphenated to mass spectrometry and can follow different strategies: target, suspect and non-target analysis. This work aims to discuss the advantages and disadvantages of the different data acquisition workflows and data exploration approaches in mass spectrometry, but also pays attention to new developments such as ion mobility and the use of in-silico prediction tools to improve the identification capabilities in high-complex samples. This tutorial gives an insight into this emerging topic of current concern, and describes the experience gathered within different collaborations and projects supported by key research articles and illustrative practical examples.
