Fenethylline, also known by the trade name Captagon, is a synthetic psychoactive stimulant that has recently been linked to a substance-use disorder and 'pharmacoterrorism' in the Middle East. Although fenethylline shares a common phenethylamine core with other amphetamine-type stimulants, it also incorporates a covalently linked xanthine moiety into its parent structure. These independently active pharmacophores are liberated during metabolism, resulting in the release of a structurally diverse chemical mixture into the central nervous system...

Use of novel psychoactive substances (NPS) such as synthetic cannabinoids (e.g., "Spice," "Serenity") and cathinones (e.g., "bath salts") has proliferated in recent years; however, there is a gap in research examining prevalence among offender samples. This study examined demographics, drug use, mental health characteristics, and criminal histories of NPS users compared to non-NPS users within an offender sample entering drug treatment. Using logistic regression analysis, combined 2013-2015 assessment data were examined (N = 8,791)...

Δ-9-tetrahydrocannabinol (THC) is the main psychoactive component of marijuana and has potent effects on decision-making, including a proposed reduction in cognitive flexibility. We demonstrate here that acute THC administration differentially affects some of the processes that contribute to cognitive flexibility. Specifically, THC reduces lose-shift responding in which female rats tend to immediately shift choice responses away from options that result in reward omission on the previous trial. THC, however, did not impair the ability of rats to flexibly bias responses toward feeders with higher probability of reward in a reversal task...

BACKGROUND: Data on both known and unknown drug use in the electronic dance music (EDM) scene is important to inform prevention and harm reduction. While surveys are the most common method of querying drug use, additional biological data can help validate use and detect unknown/unintentional use of drugs such as new psychoactive substances (NPS). We sought to determine the extent of both known and unknown use of various substances in this high-risk scene. METHODS: We hair-tested 90 self-reported past-year ecstasy/MDMA/Molly users attending EDM parties in New York City during the summer of 2016 using UHPLC-MS/MS...

The main psychoactive compound in marijuana, Δ9-tetrahydrocannabinol (THC), and its metabolites are emerging organic contaminants that have been detected in waste and surface waters. As legalization of marijuana for medical and recreational use continues, the effects of increased use and potency of marijuana on water and wastewater treatment processes and the environment should be considered. This study examined degradation kinetics of the main urinary metabolite of THC, 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) with chlorine...

Although Cannabis sativa L. is one of the most versatile plant species with multipurpose use both as medical, alimentary source and as psychoactive abuse, its biomedical relevance focused the attention on major cannabinoids. Phytochemical characterization of cannabis highlights the presence of various non-cannabinoids constituents including flavonoids, spiroindans, dihyrostilbenes, dihydrophenanthrenes, lignanamides, steroids and alkaloids. Cannabis is a plant with high pharmacological and nutrition values, its potentialities and applications are not only circumscribed to cannabinoids biological activities, but also defined by non-cannabinoid compounds...

Synthetic cannabinoids (SC) are the largest class of new psychoactive substances (NPS), and are increasingly associated with serious adverse effects. The majority of SC NPS are 1,3-disubstituted indoles and indazoles featuring a diversity of subunits at the 1- and 3-positions. Most recently, cumyl-derived indole- and indazole-3-carboxamides have been detected by law enforcement agencies and by emergency departments. Herein we describe the synthesis, characterization, and pharmacology of SCs CUMYL-BICA, CUMYL-PICA, CUMYL-5F-PICA, CUMYL-PINACA, CUMYL-5F-PINACA, and related analogues...

New psychoactive substances (NPS) are an increasing problem in clinical and forensic toxicology. The knowledge of their metabolism is important for toxicological risk assessment and for developing toxicological urine screenings. Considering the huge numbers of NPS annually appearing on the market, metabolism studies should be realized in a fast, simple, cost efficient, and reliable way. Primary human hepatocytes (PHH) were recommended to be the gold standard for in vitro metabolism studies as they are expected to contain natural enzyme clusters, co-substrates, and drug transporters...

A survey was conducted during 2015 to monitor psychoactive substance use in a sample of drivers in Spanish roads and cities. Traffic police officers recruited drivers at sites carefully chosen to achieve representativeness of the driver population. A brief questionnaire included the date, time, and personal and driving patterns data. Alcohol use was ascertained through ethanol breath test at the roadside and considered positive if concentrations >0.05mg alcohol/L were detected. Four drug classes were assessed on-site through an oral fluid screening test that, if positive, was confirmed through a second oral fluid sample at a reference laboratory...

: Alprazolam is one of the most widely prescribed benzodiazepines for the treatment of generalized anxiety disorder and panic disorder. Its clinical use has been a point of contention as most addiction specialists consider it to be highly addictive, given its unique psychodynamic properties which limit its clinical usefulness, whereas many primary care physicians continue to prescribe it for longer periods than recommended. Clinical research data has not fully shed light on its "abuse liability," yet it is one of the most frequently prescribed benzodiazepines...

Cannabis sativa subspecies, known as industrial hemp (C. sativa sativa) and marijuana (C. sativa indica) show no evident morphological distinctions, but they contain different levels of psychoactive Δ-9-tetrahidrocanabinol (THC), with considerably higher concentration in marijuana than in hemp. C. sativa subspecies differ in sequence of tetrahydrocannabinolic acid (THCA) synthase gene, responsible for THC production, and only one active copy of the gene, distinctive for marijuana, is capable of producing THC in concentration more then 0,3% in dried plants, usually punishable by the law...

Synthetic cannabinoids (SCs) continue to be the largest group of new psychoactive substances (NPS) monitored by the European Monitoring Center of Drugs and Drugs of Abuse (EMCDDA). The identification and subsequent prohibition of single SCs has driven clandestine chemists to produce analogues of increasing structural diversity, intended to evade legislation. That structural diversity, combined with the mostly unknown metabolic profiles of these new SCs, poses a big challenge for the conventional targeted analytical assays, as it is difficult to screen for 'unknown' compounds...
