The emergence of designer drugs as substances of abuse has seen a dramatic increase over the last few years. Customs officials are responsible for the control of products entering the European Union (EU) market. This control applies to chemicals in general, pharmaceutical products and medicines. Numerous products imported from non-EU countries, often -declared as 'bath salts' or 'fertilizers', may in fact contain new psychoactive substance (NPS). These are not necessarily controlled under international law, but are subject to monitoring in agreement with EU legislation...

In this paper results of a pilot study on the profiling of the synthetic cannabinoid receptor agonist 5F-PB-22 (5F-QUPIC, pentylfluoro-1H-indole-3-carboxylic acid-8-quinolinyl ester) via isotope ratio mass spectrometry are presented. It is focused on δ13 C, δ15 N and δ2 H isotope ratios, which are determined using elemental analyser (EA) and high temperature elemental analyser (TC/EA) coupled to an isotope ratio mass spectrometer (IRMS). By means of a sample of pure material of 5F-PB-22 it is shown that the extraction of 5F-PB-22 from herbal material, a rapid clean-up procedure, or preparative column chromatography had no influences on the isotope ratios...

α-Pyrrolidinoheptiophenone (PV8) is a representative of α-pyrrolidinophenone derivatives, a new group of synthetic cathinones. PV8 was first detected in illegal products in Japan in 2013. It is closely related to α-pyrrolidinovalerophenone (α-PVP), which was one of the most popular novel psychoactive substance (NPS) in Poland in years 2013-2015. The article presents two cases of fatal poisonings of 36-year-old man and 37-year-old woman, where a new cathinone derivative - PV8 was detected in biological material collected during medicolegal autopsies...

Several new psychoactive substances (NPS) have reached the illegal drug market in recent years, and ecstasy-like tablets are one of the forms affected by this change. Cathinones and tryptamines have increasingly been found in ecstasy-like seized samples as well as other amphetamine type stimulants. A presumptive method for identifying different drugs in seized ecstasy tablets (n=92) using ATR-FTIR (attenuated total reflectance - Fourier transform infrared spectroscopy) and PLS-DA (partial least squares discriminant analysis) was developed...

AIM: The aim of this study was to examine the typology of Australian illicit drug consumers to determine whether those who use new psychoactive substances (NPS) differ from those using other illicit substances. METHODS: Data were from the 2013 National Drug Strategy Household Survey, a representative population study; analyses were limited to participants reporting past year illicit drug use (including NPS; n = 3309). Latent class analysis identified groups based on past year substance use, and a weighted multivariable, multinomial regression model was used to examine characteristics associated with group membership...

n-Ethyl pentylone (NEP) is a chemical substance derived from cathinone. Synthetic cathinones are an evolving group of drugs with stimulating, mind-altering effects sometimes referred to as novel or new psychoactive substances (NPS). There is scarce information in the medical literature regarding forensic cases in which NEP is detected in toxicological testing. We present four fatalities involving NEP from Alabama in 2017. Deaths were attributed to NEP toxicity in two cases (peripheral blood concentrations of 0...

RATIONALE: Drug overdose deaths due to fentanyls and other novel psychoactive substances (NPS) are on the rise. The higher potencies of fentanyl analogs compared with morphine require new technologies to identify and quantitate NPS. METHODS: Paper spray tandem mass spectrometry and high-resolution mass spectrometry were used to identify and measure fentanyl analogs as well as common drugs of abuse in urine samples from substance use disorder clinics. Ten-microliter urine samples were deposited directly on paper spray cartridges previously loaded with internal standards, dried, and analyzed with no other sample treatment...

The number of new psychoactive substances (NPS) increases rapidly, harming society and fuelling the need for alternative testing strategies. These should allow the ever-increasing number of drugs to be tested more effectively for their toxicity and psychoactive effects. One proposed strategy is to complement rodent models with zebrafish ( Danio rerio ) larvae. Yet, our understanding of the toxicokinetics in this model, owing to the waterborne drug exposure and the distinct physiology of the fish, is incomplete...

BACKGROUND/OBJECTIVE: We report on a case of severe intoxication after insufflation of U-47700, a synthetic opioid that acts as a selective agonist of the µ-opioid receptor, several times more potent than morphine. A man in his 30s was found irresponsive in his apartment and was brought to the emergency department of a local hospital. A comatous state and severe respiratory depression were diagnosed. Anamnesis revealed that the patient could have taken the substance named "U-47700", bought in the Internet...

Continued diversification and use of new psychoactive substances (NPS) across Europe remains a public health challenge. The study describes health and social consequences of recent NPS use as reported in a survey of marginalised, nightlife and online NPS users in the Netherlands, Hungary, Portugal, Ireland, Germany and Poland ( n  = 3023). Some respondents were unable to categorise NPS they had used. Use of ' herbal blends ' and ' synthetic cannabinoids obtained pure ' was most reported in Germany, Poland and Hungary, and use of ' branded stimulants ' and ' stimulants/empathogens/nootropics obtained pure ' was most reported in the Netherlands...

The availability of new psychoactive substances on the recreational drug market continues to create challenges for scientists in the forensic, clinical and toxicology fields. Phenmetrazine (3-methyl-2-phenylmorpholine) and an array of its analogs form a class of psychostimulants that are well documented in the patent and scientific literature. The present study reports on two phenmetrazine analogs that have been encountered on the NPS drug market following the introduction of 3-fluorophenmetrazine (3-FPM), namely 4-methylphenmetrazine (4-MPM) and 3-methylphenmetrazine (3-MPM)...

In this communication, we present the first developed Molecularly Imprinted Polymers (MIPs) for the specific detection of a New Psychoactive Substance (NPS); namely, methoxphenidine (MXP) and its regioisomers. Selectivity of the MIP towards MXP is studied by analysing mixtures and an acquired street sample with High Performance Liquid Chromatography coupled to UV detection. The study demonstrates that the engineered polymers selectively extract MXP from heterogeneous samples, which makes for a very powerful diagnostic tool that can detect traces of MXP in complicated NPS samples...

BACKGROUND: Recent developments in drug use patterns call for an investigation of current party-drug use and associated problems among college students, who appear to be an important target population for harm reduction interventions. OBJECTIVES: In addition to reporting on party-drug use prevalence, we investigated whether initial use and continuation of party-drug use among students was associated with demographic, personality and psychosocial factors. METHODS: An online questionnaire was administered to 446 students from a Dutch university, inquiring about party-drug use, demographic characteristics, social norms and personality (big five, impulsiveness, aggression)...

Comprehensive screening procedures for psychoactive agents in body fluids are an essential task in clinical and forensic toxicology. With the continuous emergence and adaption of new psychoactive substances (NPS) keeping a screening method up to date is challenging. To meet these demands, hyphenated high-resolution mass spectrometry has gained interest as extensive and expandable screening approach. Here we present a comprehensive method for systematic toxicological analysis of serum by liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) with data independent acquisition...

Substance misuse services need to meet the growing demand and needs of individuals using new psychoactive substances (NPS). A review of the literature identified a paucity of research regarding NPS use by these individuals and UK guidelines outline the need for locally tailored strategies. The purpose of this qualitative study was to identify and explore key themes in relation to the use of NPS by individuals receiving community treatment for their substance use. Electronic records identified demographics and semi-structured interviews were undertaken...

While the prevalence and the use of new psychoactive substances (NPS) is steadily increasing, data on pharmacological, toxicological and clinical effects is limited. Considering the large number of NPS available, there is a clear need for efficient in vitro screening techniques that capture multiple mechanisms of action. Neuronal cultures grown on multi-well microelectrode arrays (mwMEAs) have previously proven suitable for neurotoxicity screening of chemicals, pharmaceuticals and (illicit) drugs. We therefore used rat primary cortical cultures grown on mwMEA plates to investigate the effects of eight NPS (PMMA, α-PVP, methylone, MDPV, 2 C-B, 25B-NBOMe, BZP and TFMPP) and two 'classic' illicit drugs (cocaine, methamphetamine) on spontaneous neuronal activity...
