Shawn M Aarde, Michael A Taffe
Animal models of drug self-administration are currently the gold standard for making predictions regarding the relative likelihood that a recreational drug substance will lead to continued use and addiction. Such models have been found to have high predictive accuracy and discriminative validity for a number of drug classes including ethanol, nicotine, opioids, and psychostimulants such as cocaine and methamphetamine. Members of the entactogen class of psychostimulants (drugs that produce an "open mind state" including feelings of interpersonal closeness, intimacy and empathy) have been less frequently studied in self-administration models...

The nature of the global drugs market has evolved rapidly and has become more complex with the emergence of new psychoactive substances (NPS), some of which have been associated with increased abuse, hospital emergency admissions and sometimes fatalities. NPS are characterized by geographic heterogeneity, with some only transient in nature and others not satisfying the criteria for harm required for international control. Consequently, a pragmatic response of the international community is to prioritize the most harmful, persistent and prevalent substances for action - an objective, which is hampered by the paucity of data on harms...

Advances in chemistry, technology, and globalization have contributed to the rapid development and diffusion of NPS (new psychoactive substances), creating perhaps the most serious challenge to the century-old international drug control system and to national systems. Very little is known about the effects of these substances which fall outside of national and international controls. The predominant response to the flood of NPS has been the development of more expeditious methods of prohibiting a new chemical entity...

An analytical method using ultra performance liquid chromatography (UPLC) quadrupole time-of-flight mass spectrometry (QTOF-MS) was developed and validated for the targeted toxicological screening and quantification of commonly used pharmaceuticals and drugs of abuse in postmortem blood using 100 µL sample. It screens for more than 185 drugs and metabolites and quantifies more than 90 drugs. The selected compounds include classes of pharmaceuticals and drugs of abuse such as: antidepressants, antipsychotics, analgesics (including narcotic analgesics), anti-inflammatory drugs, benzodiazepines, beta-blockers, amphetamines, new psychoactive substances (NPS), cocaine and metabolites...

BACKGROUND: Novel psychoactive substances (NPS) are new narcotic or psychotropic drugs that are not controlled by the United Nations drug convention that may pose a serious public health threat due to their wide availability for purchase on the internet and in so called "head shops." Yet, the extent of their global use remains largely unknown. The aim of this study is to conduct a systematic review of the prevalence of NPS use in non-clinical populations. METHODS: This is a systematic review of observational studies...

In the course of the last decade, a substantial growth of new psychoactive substances (NPS) has been recorded. Within this group, a considerably fast growing sub-group is represented by the opioids, which are based on modifications of the fentanyl structure. In this study, identification and analytical characterization of a new fentanyl derivative, 4-fluorobutyrfentanyl (1-((4-fluorophenyl)(1-phenethylpiperidin-4-yl)amino)butan-1-one, 4-FBF), is described. Apart from the seized powder, 4-FBF was also identified in the e-cigarette liquid secured in Case 1...

New Psychoactive Substances (NPS) belong to several chemical classes, including phenethylamines, piperazines, synthetic cathinones and synthetic cannabinoids. Development and validation of analytical methods for the determination of NPS both in traditional and alternative matrices is of crucial importance to study drug metabolism and to associate consumption to clinical outcomes and eventual intoxication symptoms. Among different biological matrices, hair is the one with the widest time window to investigate drug-related history and demonstrate past intake...

BACKGROUND: Evolutionary research on drug abuse has hitherto been restricted to proximate studies, considering aetiology, mechanism, and ontogeny. However, in order to explain the recent emergency of a new behavioral pattern (e.g. 'the e-psychonaut style') of novel psychoactive substances' (NPS) intake, a complementary evolutionary model may be needed. OBJECTIVE: A range of evolutionary interpretations on the 'psychonaut style' and the recent emergency of NPS was here considered...

Metabolite profiling of novel psychoactive substances (NPS) is critical for documenting drug consumption. N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-(4-fluorobenzyl)-1H-indazole-3-carboxamide (ADB-FUBINACA) is an emerging synthetic cannabinoid whose toxicological and metabolic data are currently unavailable. We aimed to determine optimal markers for identifying ADB-FUBINACA intake. Metabolic stability was evaluated with human liver microsome incubations. Metabolites were identified after 1 and 3 h incubation with pooled human hepatocytes, liquid chromatography- high resolution mass spectrometry in positive-ion mode (5600+ TripleTOF®, Sciex) and several data mining approaches (MetabolitePilot™, Sciex)...

The popularity of new psychoactive substances (NPS) has grown in recent years, with certain NPS commonly and preferentially consumed even following the introduction of preventative legislation. With the objective to improve the knowledge on the use of NPS, a rapid and very sensitive method was developed for the determination of ten priority NPS (N-ethylcathinone, methylenedioxypyrovalerone (MDPV), methylone, butylone, methedrone, mephedrone, naphyrone, 25-C-NBOMe, 25-I-NBOMe and 25-B-NBOMe) in influent wastewater...

High-resolution mass spectrometry (HRMS) is widely used for the drug screening of biological samples in clinical and forensic laboratories. With the continuous addition of new psychoactive substances (NPS), keeping such methods updated is challenging. HRMS allows for combined targeted and non-targeted screening; first, peaks are identified by software algorithms, and identifications are based on reference standard data. Remaining unknown peaks are attempted identified with in silico and literature data. However, several thousand peaks remain where most are unidentifiable or uninteresting in drug screening...

Increasing numbers of new psychoactive substances (NPS) among them fentanyl derivatives has been reported by the European monitoring centre for drugs and drug addiction (EMCDDA). Butyrfentanyl is a new fentanyl derivative whose potency ratio was found to be seven compared to morphine and 0.13 compared to fentanyl. Several case reports on butyrfentanyl intoxications have been described. Little is known about its pharmacokinetic properties including its metabolism. However, knowledge of metabolism is essential for analytical detection in clinical and forensic toxicology...

New psychoactive substances (NPS) have become an increasing drug problem in the past decade. For detection of NPS, new analytical methods have to be developed, and the methods also have to be updated regularly. This study aimed at developing a multi-component LC-MS/MS method for detection and quantification of 11 NPS of the benzodiazepine sub-class ("designer benzodiazepines") in urine specimens. The method involves dilution of urine with internal standard and hydrolysis of any glucuronide conjugated forms...

Although some novel psychoactive substances (NPS) are newly discovered chemicals, others are traditional or indigenous substances that are introduced to new markets. One of these latter substances is a plant many people refer to as kratom. Indigenous to Southeast Asia and used for a variety of instrumental and recreational purposes, kratom has recently become available to Western drug users. Kratom is somewhat unique in that the plant contains two different psychoactive chemicals, which have both stimulant (mitragynine) and narcotic (7-hydroxymitragynine) properties...

BACKGROUND: Illegal drug use has long been a global concern. Taiwan and Korea are geographically adjacent and both countries have experienced the illegal use problems of methamphetamine, a predominant prototype of New Psychoactive Substances (NPS). NPS, a term coined by the United Nations Office on Drugs and Crime (UNODC) in recent years, have not been scrutinized for their safety and may become a new threat to public health and security worldwide. To conduct evidence-based drug policy, it is imperative to estimate the trend and pattern of illegal drug use...

Prior research has documented the availability of drugs on many Tor Network websites, with the Internet playing a particularly vital role in the global new psychoactive substances (NPS) market. The primary objective of this research was to document types of NPS for sale on the largest operating Tor site (Agora) over a period of four months. Secondary objectives were to analyze countries and vendors sourcing NPS on Agora. Data from Agora were collected in February and June 2015. The number of total advertisements on Agora increased from 20,742 to 27,431 over the four months, while the number of NPS advertisements increased from 2,205 to 2,271 and the number of vendors increased from 157 to 288...
