Novel emerging drugs of abuse, also referred as new psychoactive substances (NPS), constitute an ever-changing mixture of chemical compounds designed to circumvent legislative controls by means of chemical modifications of previously banned recreational drugs. One of such class, synthetic cathinones, namely β-keto derivatives of amphetamines, has been largely abused over the past decade. A number of new synthetic cathinones are detected each year, either in bulk powders/crystals or in biological matrices. It is therefore important to continuously monitor the supply of new synthetic derivatives and promptly report them...

The appearance and spread of new psychoactive substances (NPS) is a phenomenon detected throughout Europe since 2008. Synthetic cathinones, a group of NPS, have been self-reported as the drug injected by the vast majority of people who inject drugs (PWID) in Hungary. This study aims at updating our knowledge on what exactly the compounds injected by PWID. This multi-site study analysed residues from used injecting drug paraphernalia collected from PWID via low threshold services and from public places in Budapest, Debrecen, Miskolc, Szeged, Békéscsaba and Pécs between March 2015 and February 2016...

Despite the implementation of the new blanket scheduling system in 2013, new psychoactive substance (NPS) abuse remains a serious social concern in Japan. We present a fatal intoxication case involving 5F-ADB (methyl 2-[1-(5-fluoropentyl)-1H-indazole-3-carboxamido]-3,3-dimethylbutanoate) and diphenidine. Postmortem blood screening by liquid chromatography/quadrupole time-of-flight mass spectrometry (LC/Q-TOFMS) in the information dependent acquisition (IDA) mode only detected diphenidine. Further urinary screening using an in-house database containing new NPS and metabolites detected not only diphenidine but also possible 5F-ADB metabolites; subsequent targeted screening by LC/tandem mass spectrometry (LC/MS/MS) allowed for the detection of very low level of unchanged 5F-ADB in postmortem heart blood...

Ritva Karinen, Gudrun Høiseth
Interpretation of blood concentrations of new psychoactive substances (NPS) requires comparison of the results to previously published case reports; as only a few experimental studies for these substances exist. A large number of articles representing single or multiple cases have been published for a great number of substances, making a unified overview difficult. In this review we have collected all published blood concentrations from the NPS groups classified as phenethylamines, aminoindanes, arylalkylamines, arylcyclohexylamines, and indolalkylamines, and also included unpublished results for MPA, MXE, 4-FMA, 4-FA and 4-MA analyzed in our laboratory...

OBJECTIVE: To examine the purchasing and supply patterns of new psychoactive substance (NPS) consumers in Australia. METHOD: Data were obtained from a self-selected sample of 296 past-year NPS consumers, with comparisons made across dimethyltryptamine (n = 104), 2C-x (n = 59), NBOMe (n = 27), and synthetic cannabinoid (n = 22) users. RESULTS: Most consumers (58%) nominated a friend as their main NPS source, and almost half (46%) reported that they had supplied NPS to others in the past year (predominantly "social supply")...

New psychoactive substances (NPS) are commonly referred to as "research chemicals", "designer drugs" or "legal highs." One NPS class is represented by dissociative anesthetics, which include analogues of the arylcyclohexylamine phencyclidine (PCP), ketamine, and diphenidine. A recent addition to the NPS market was 4-[1-(3-methoxyphenyl)cyclohexyl]morpholine (3-MeO-PCMo), a morpholine analogue of 3-MeO-PCP. Although suspected to have dissociative effects in users, information about its pharmacological profile is not available...

The prevalence and use of new psychoactive substances (NPS) is increasing and currently over 600 NPS exist. Many illicit drugs and NPS increase brain monoamine levels by inhibition and/or reversal of monoamine reuptake transporters (DAT, NET and SERT). This is often investigated using labor-intensive, radiometric endpoint measurements. We investigated the applicability of a novel and innovative assay that is based on a fluorescent monoamine mimicking substrate. DAT, NET or SERT-expressing human embryonic kidney (HEK293) cells were exposed to common drugs (cocaine, dl-amphetamine or MDMA), NPS (4-fluoroamphetamine, PMMA, α-PVP, 5-APB, 2C-B, 25B-NBOMe, 25I-NBOMe or methoxetamine) or the antidepressant fluoxetine...

The influx of new psychoactive substances (NPS) has created a need for improved methods for drug testing in toxicology laboratories. The aim of this work was to design, validate and apply a multi-analyte liquid chromatography-high resolution mass spectrometry (LC-HRMS) method for screening of 148 target analytes belonging to the NPS class, plant alkaloids and new psychoactive therapeutic drugs. The analytical method used a five-fold dilution of urine with 9 deuterated internal standards and injection of 2 μL...

BACKGROUND: New psychoactive substances (NPS) continue to emerge; however, few surveys of substance use ask about NPS use. Research is needed to determine how to most effectively query use of NPS and other uncommon drugs. OBJECTIVE: To determine whether prevalence of self-reported lifetime and past-year use differs depending on whether or not queries about NPS use are preceded by "gate questions." Gate questions utilize skip-logic, such that only a "yes" response to the use of specific drug class is followed by more extensive queries of drug use in that drug class...

REVIEW

The market for new psychoactive substances has increased markedly in recent years and there is now a steady stream of compounds appearing every year. Benzodiazepines consist of only a fraction of the total number of these compounds but their use and misuse has rapidly increased. Some of these benzodiazepines have only been patented, some of them have not been previously synthesised and the majority have never undergone clinical trials or tests. Despite their structural and chemical similarity, large differences exist between the benzodiazepines in their pharmacokinetic parameters and metabolic pathways and so they are not easily comparable...

Novel psychoactive substances (NPS) represent significant analytical and interpretive challenges to forensic and clinical toxicologists. Timely access to case reports and reports of adverse incidents of impairment or toxicity is imperative to clinical diagnosis and treatment, as well as to interpretation of forensic results. Delays in identifying the presence of a novel intoxicating agent have significant consequences for public health and public safety. Adverse effects of intoxications with novel cannabinoids, stimulants, hallucinogens, benzodiazepines and opioids spanning January 2013 through December 2016 as reported in emergency departments, death investigations, impaired driving cases and other forensic contexts are the subject of this review...

The use of new psychoactive substances (NPS) is steadily increasing. One commonly used NPS is methoxetamine (MXE), a ketamine analogue. Several adverse effects have been reported following MXE exposure, while only limited data are available on its neuropharmacological modes of action. We investigated the effects of MXE and ketamine on several endpoints using multiple in vitro models. These included rat primary cortical cells, human SH-SY5Y cells, human induced pluripotent stem cell (hiPSC)-derived iCell(®) Neurons, DopaNeurons and astrocyte co-cultures, and human embryonic kidney (HEK293) cells...

Over the last few years, hundreds of new psychoactive substances (NPS) have been identified in Europe. Apart from some herbal compounds, NPS mainly include synthetic cannabinoids and a range of new synthetic stimulants (e. g., cathinones). Synthetic NPS are often developed whilst modifying the basic chemical (e. g., phenethylamine or tryptamine) structure. Although the pharmacology and toxicology of most NPS are hardly known, they are being offered, especially online, as "bath salts," as "incense mixtures," or under other misleading labels...

Today there is continued, and in some cases growing, availability of psychoactive substances, including treatments for mental health disorders such as cognitive enhancers, which can enhance or restore brain function, but also 'recreational' drugs such as novel psychoactive substances (NPS). The use of psychoactive drugs has both benefits and risks: whilst new drugs to treat cognitive symptoms in neuropsychiatric or neurodegenerative disorders could have great benefits for many patient groups, the increasing ease of accessibility to recreational NPS and the increasing lifestyle use of cognitive enhancers by healthy people means that the effective management of psychoactive substances will be an issue of increasing importance...

INTRODUCTION AND AIMS: New psychoactive substances (NPS) have hedonic effects that may lead to dependence. Headshops selling NPS increased in number in Ireland from late 2009. Legislation was enacted in May and August of 2010 that caused their closure. It is unknown whether such events impact the rate of NPS use disorders. DESIGNS AND METHODS: We conducted a population-based study using the Irish national database of episodes of addiction treatment between 2009 and 2012...

Indole or indazole-based synthetic cannabinoids (SCs) bearing substituents derived from valine or tert-leucine are frequently abused new psychoactive substances (NPS). The emergence of 5F-MDMB-PICA (methyl N-{[1-(5-fluoropentyl)-1H-indol-3-yl]carbonyl}-3-methylvalinate) on the German drug market is a further example of a substance synthesized in the context of scientific research being misused by clandestine laboratories by adding it to 'legal high' products. In this work, we present the detection of 5F-MDMB-PICA in several legal high products by gas chromatography-mass spectrometry (GC-MS) analysis...

2-Amino-1-(4-bromo-2,5-dimethoxyphenyl)ethanone hydrochloride (bk-2C-B) has recently emerged as a new psychoactive substance (NPS). It is most commonly consumed orally although there are indications that it might also be ingested by inhalation or 'smoking'. Information about the stability of bk-2C-B when exposed to heat is unavailable and the potential for pyrolytic degradation and formation of unknown substances available for inhalation prompted an investigation using a simulated 'meth pipe' scenario. Twelve products following pyrolysis of bk-2C-B were detected and verified by organic synthesis of the corresponding standards...
