Abstract Purpose This publication reports analytical properties of the designer benzodiazepine 8-chloro-6-(2-fluorophenyl)-1-methyl-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine (flualprazolam) seized in an anesthesia robbery case. Methods The target compound was identified by liquid chromatography–quadrupole time-of-flight-mass spectrometry (LC–QTOF-MS), gas chromatography–mass spectrometry (GC–MS), and nuclear magnetic resonance (NMR) spectroscopy. Results We could obtain detailed analytical data of flualprazolam—a new designer benzodiazepine available on the designer drug market. Conclusions More designer benzodiazepines have been detected and seized on the illegal drug scene as new psychoactive substances during the last 5 years. In this study, we presented analytical data of flualprazolam to assist forensic laboratories that encounter these newly emerging compounds in casework. This is the first report on this compound in illegal products.

The rapid diffusion of new psychoactive substances (NPS) presents unprecedented challenges to both customs authorities and analytical laboratories involved in their detection and characterization. In this study an analytical approach to the identification and structural elucidation of a novel synthetic cannabimimetic, quinolin-8-yl-3-[(4,4-difluoropiperidin-1-yl) sulfonyl]-4-methylbenzoate (2F-QMPSB), detected in seized herbal material, is detailed. An acid precursor 4-methyl-3-(4,4-difluoro-1-piperidinylsulfonyl) benzoic acid (2F-MPSBA), has also been identified in the same seized material. After extraction from the herbal material the synthetic cannabimimetic, also referred to as synthetic cannabinoid receptor agonists or “synthetic cannabinoids”, was characterized using gas chromatography-mass spectrometry (GC-MS), 1H, 13C, 19F and 15N nuclear magnetic resonance (NMR) and high-resolution tandem mass spectrometry (HR-MS/MS) combined with chromatographic separation. A cheminformatics platform was used to manage and interpret the analytical data from these techniques.

The use of the new psychoactive substances is continuously growing and the implementation of accurate and sensible analysis in biological matrices of users is relevant and fundamental for clinical and forensic purposes. Two different analytical technologies, high-sensitivity gas chromatography-mass spectrometry (GC-MS) and ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) were used for a screening analysis of classic drugs and new psychoactive substances and their metabolites in urine of formed heroin addicts under methadone maintenance therapy. Sample preparation involved a liquid-liquid extraction. The UHPLC-HRMS method included Accucore™ phenyl Hexyl (100 × 2.1 mm, 2.6 μm, Thermo, USA) column with a gradient mobile phase consisting of mobile phase A (ammonium formate 2 mM in water, 0.1% formic acid) and mobile phase B (ammonium formate 2 mM in methanol/acetonitrile 50:50 (v/v), 0.1% formic acid) and a full-scan data-dependent MS2 (ddMS2) mode for substances identification (mass range 100–1000 m/z). The GC-MS method employed an ultra-Inert Intuvo GC column (HP-5MS UI, 30 m, 250 µm i.d, film thickness 0.25 µm; Agilent Technologies, Santa Clara, CA, USA) and electron-impact (EI) mass spectra were recorded in total ion monitoring mode (scan range 40–550 m/z). Urine samples from 296 patients with a history of opioid use disorder were examined. Around 80 different psychoactive substances and/or metabolites were identified, being methadone and metabolites the most prevalent ones. The possibility to screen for a huge number of psychotropic substances can be useful in suspected drug related fatalities or acute intoxication/exposure occurring in emergency departments and drug addiction services.

IntroductionNew psychoactive substances (NPS) are substances that have recently appeared on the market and are not under international control. NPS use is experiencing an unprecedented increase. DiPT, 4-HO-DiPT and 4-AcO-DiPT are new psychoactive tryptamines and their effects may differ from those of other psychoactive tryptamines.ObjectiveTo explore the presence of DiPT, 4-HO-DiPT and 4-AcO-DiPT from samples delivered to and analyzed by Spanish harm reduction service Energy Control.Materials and methodsAll samples analyzed from 2009 to 2014 delivered as DiPT, 4-HO-DiPT and 4-AcO-DPT or containing these substances. Analysis was performed by gas chromatography–mass spectrometry.ResultsFrom 17,432 samples, 4-HO-DiPT was found in 16, delivered as 4-HO-DiPT (6); 4-AcO-DiPT (7); DiPT (1); 4-AcO-DMT (1) and cocaine (1). 4-AcO-DiPT was found in 16, delivered as 4-AcO-DiPT (12); 5-MeO-DMT (1); 5-MeO-DiPT (1); 4-AcO-DMT (1) and cocaine (1). Only 4 samples contained DiPT, all presented as DiPT. Nine samples contained both 4-AcO-DiPT and 4-HO-DiPT. During the years of study, 4-HO-DiPT deliverance was increasing (4 samples in 2014) while deliverance of 4-AcO-DiPT and DiPT was decreasing (1 sample in 2014).ConclusionsIncreasing 4-HO-DiPT presence could translate a progressive replacement of 4-AcO-DiPT and DiPT recreational use. Clinical relevance comes from its growing use and the absence of scientific evidence on humans, therefore relying on users subjective experience to predict the effects.Disclosure of interestThe authors declare that they have no competing interest.

IntroductionNew Psychoactive Substances (NPS) appear to be increasing in popularity because they mimic the effect of traditional drugs. DOB is a world-wide controlled phenethylamine, with agonist activity in 5HT2A receptors. Its effects are comparable to those of LSD, with dosage range 1.0–3.0 mg and duration 18–30 h.ObjectiveTo assess the presence of DOB in the substances submitted to, and analyzed by, energy control.Materials and methodsAll samples presented to Energy Control (EC) from August 2009 to August 2015 were analyzed. EC is a spanish harm-reduction non governmental organization that offers to users the possibility of analyzing the substances they intend to consume. Samples in which DOB was detected using gas chromatography-mass spectrometry were selected for this study.ResultsFrom a total of 20,062 samples, 13 contained DOB (0,06%), with no clear variations among the years studied. The samples were mostly sold as DOC(8), DOB(2) and LSD(2). Nine out of total 13 samples presented as blotter.ConclusionResults suggest that availability of DOB in the Spanish drug market is anecdotic. Nonetheless, a number of the samples containing DOB were not sold as such, increasing the possibility of side effects, as users may ignore which substance they are actually using. When a patient presents at an Emergency Department with persistent hallucinogenic symptomatology after ingesting a blotter, psychiatrist should be aware of long-lasting psychedelics such as DOB.Disclosure of interestThe authors have not supplied their declaration of competing interest.
