Drosophila melanogaster can be used to identify genes with novel functional roles in neuronal plasticity induced by repeated consumption of addictive drugs. Behavioral sensitization is a relatively simple behavioral output of plastic changes that occur in the brain after repeated exposures to drugs of abuse. The development of screening procedures for genes that control behavioral sensitization has stalled due to a lack of high-throughput behavioral tests that can be used in genetically tractable organism, such as Drosophila ...

Increased experimentation with easily accessible synthetic opioids is posing a hazard to the public. We discuss one such synthetic opioid, U-50488. Much is unknown about U-50488; however, due to its structural similarity to U-47700, there is possible risk associated with its use. Curtailing the use of synthetic opioids such as U-50488 will require a concerted effort targeting multiple problems.

Since the turn of the century, the synthesis, availability and use of new psychoactive substances (NPS) have been increasingly reported worldwide, being currently considered a complex global phenomenon. As most NPS are not detected in routine drug screening, an extra effort has been made to develop new analytical methods for the detection of these compounds, with several approaches being successfully applied and reported in the literature. The increased traffic of NPS is often related to limited capacity for detecting and monitoring these compounds, which makes essential to explore in detail both conventional and more recent approaches to prospect novel sensing strategies and develop in-the-field sensors able to detect NPS in a time efficient manner, within a wide range of concentrations, in a variety of sample matrices such as biological samples, wastewater, powders, crystals and post-mortem specimens...

Synthetic cannabinoids are psychoactive substances designed to mimic the euphorigenic effects of the natural cannabis. Novel unregulated compounds appear once older compounds become illegal. It has been previously reported that synthetic cannabinoids are different than Δ9 -tetrahydrocannabinol (Δ9 -THC) as they have chemical structures unrelated to Δ9 -THC, different metabolism and, often, greater toxicity. This study aimed to investigate the effects of three novel synthetic cannabinoids and pure Δ9 -THC on body temperature, nociceptive threshold, anxiety, memory function, locomotor and exploratory parameters, and depression...

Background: This review aimed to address what was known about the public health burden associated with novel psychoactive substances (NPS) use, and the effectiveness of responses targeting NPS use and/or associated problems. Methods: Relevant literature was identified through a range of searches covering the period from January 2006 to June 2016. Data synthesis was undertaken in three stages. Firstly we mapped the evidence available in order to characterize the literature according to a set of analytic categories developed a priori...

Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, a rigorous comparative analysis of the phenomenology ("what it feels like" to experience these states) is currently lacking. We investigated the semantic similarity between a large number of subjective reports of psychoactive substances and reports of high/low lucidity dreams, and found that the highest-ranking substance in terms of the similarity to high lucidity dreams was the serotonergic psychedelic lysergic acid diethylamide (LSD), whereas the highest-ranking in terms of the similarity to dreams of low lucidity were plants of the Datura genus, rich in deliriant tropane alkaloids...

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)...

: Novel psychoactive substance use is a major social concern. Their use may elicit or uncover unpredictably as yet undescribed clinical pictures. We aimed to illustrate a multisubstance use case indistinguishable from paranoid schizophrenia, so to alert clinicians on possibly misdiagnosing substance-induced psychotic disorders. CASE REPORT: We describe a case of a 32-year-old man who started at 18 years with cannabinoids and ketamine, and is currently using N-methyl-D-aspartate (NMDA) antagonists...

Indole, indazole or azaindole based synthetic cannabinoids (SCs), bearing a cumyl substituent are a widespread, recreationally used subgroup of new psychoactive substances (NPS). The latest cumyl-derivative, CUMYL-PEGACLONE, emerged in December 2016 on the German drug market. The substance features a novel γ-carboline core structure, which is most likely synthesized to bypass generic legislative approaches to control SCs by prohibiting distinct core structures. Using liquid chromatography tandem mass spectrometry and liquid chromatography high resolution mass spectrometry techniques, the main in vivo phase I metabolites of this new substance were detected...

BACKGROUND: With the rapid development of new psychoactive substances (NPS) and changes in the use of more traditional drugs, it is increasingly difficult for researchers and public health practitioners to keep up with emerging drugs and drug terms. Substance use surveys and diagnostic tools need to be able to ask about substances using the terms that drug users themselves are likely to be using. Analyses of social media may offer new ways for researchers to uncover and track changes in drug terms in near real time...

The current study is aimed to introduce a wastewater-based epidemiology (WBE) approach for the first time on the African continent where substance abuse data is limited. The study included the quantification of several drugs of abuse (DOA) in raw wastewater samples. Quantification of urinary metabolites as drug target residues (DTR), as well as enantiomeric profiling of chiral DOA was performed to distinguish between consumption and direct disposal into sewage. Monitoring campaigns were undertaken at two South African wastewater treatment works (WWTWs) located within two provinces of the country...

Patients can use numerous drugs that exist outside of existing regulatory statutes in order to get "legal highs." Legal psychoactive substances represent a challenge to the emergency medicine physician due to the sheer number of available agents, their multiple toxidromes and presentations, their escaping traditional methods of analysis, and the reluctance of patients to divulge their use of these agents. This paper endeavors to cover a wide variety of "legal highs," or uncontrolled psychoactive substances that may have abuse potential and may result in serious toxicity...

BACKGROUND: The increasing number of legally ambiguous and precarious Novel Psychoactive Substances (NPS) constitutes a challenge for policy makers and public health. Scientific and more in-depth knowledge about the motivations for using NPS is scarce and often consist of predetermined, non-systematic, or poorly described reasons deduced from top-down approaches. Therefore, the aim of the present study was to explore and characterize the users' self-reported reasons for NPS use inductively and more comprehensively...

Novel psychoactive substances (NPS), often characterized as unregulated psychoactive compounds designed to circumvent existing legislation, have become mainstream on the illicit drug market. Because of their physical and mind-altering properties, NPS may be deliberately or inadvertently ingested at electronic dance music (EDM) festivals to enhance the attendees' appreciation of the music and overall experience. Their widespread use at EDM festivals have been well documented and several adverse events and fatalities associated with NPS ingestion have been reported in the United States...

Hallucinogen-persisting perception disorder (HPPD) is a syndrome characterized by prolonged or reoccurring perceptual symptoms, reminiscent of acute hallucinogen effects. HPPD was associated with a broader range of LSD (lysergic acid diethylamide)-like substances, cannabis, methylenedioxymethamphetamine (MDMA), psilocybin, mescaline, and psychostimulants. The recent emergence of novel psychoactive substances (NPS) posed a critical concern regarding the new onset of psychiatric symptoms/syndromes, including cases of HPPD...

Objectives: Aminoindanes ("bath salts," a class of novel psychoactive substances, NPSs) increased rapidly in popularity on the recreational drug market, particularly after mephedrone and other synthetic cathinones were banned in the UK in 2010. Novel aminoindanes continue to emerge, but relatively little is known about their effects and risks. Their history, chemistry, pharmacology, behavioral effects, pharmacokinetics, and toxicity are reviewed in this paper. Methods: Scientific literature was searched on ISI Web of Knowledge: Web of Science (WoS) during June and July 2017, using English language terms: aminoindanes such as 5,6-methylenedioxy-2-aminoindane (MDAI), 5-iodo-2-aminoindane (5-IAI), 2-aminoindane (2-AI), 5,6-methylenedioxy-N-methyl-2-aminoindane (MDMAI), and 5-methoxy-6-methyl-2-aminoindane (MMAI)...

Novel psychoactive substances (NPS), and specifically novel opioids, continue to cause adverse events, including death, within drug-using populations. As the number of opioid-related overdoses continues to increase, laboratories have identified the emergence of new fentanyl analogues and other synthetic opioid-related drugs. Tetrahydrofuranylfentanyl (THFF) has been identified in Europe and the United States as an emerging novel opioid, causing death in at least 15 drug-using individuals to date. THFF is structurally similar to furanylfentanyl, a previously characterized novel opioid responsible for numerous adverse events, including death...
