Abstract
The number of methods for the analysis of new psychoactive substances (NPS) is continually increasing, and there is no indication that this trend will change in the near future. The constantly growing market of "designer drugs" makes it necessary to develop new methods of their analysis. The aim of this review is to present the multi-component methods of detection and identification of NPS using low-resolution tandem mass spectrometry coupled with liquid chromatography. For this purpose, 36 articles were selected by applying strictly defined search criteria. Due to the large differences in the matrices and physicochemical properties of the analytes, the described research methods are diverse. These differences are visible in sample preparation methods, chromatographic columns, mobile phases, gradients, or additives to mobile phases used. This work collects and organizes the existing information on the subject of NPS screening analysis methods and will be helpful to forensic scientists working on this topic.

Abstract
Forensic laboratories need quick and simple technology to improve turnaround times, while delivering reliable results. The goal of this study is first to create a simplified workflow to meet new Academy Standards Board requirements for urine testing in drug-facilitated crime investigations and, second, to create "ready-to-go", "hands-free" testing technology to further streamline analytical procedures. A first of its kind, the ToxBox forensic test kit is used to validate a single analytical procedure for opioids, benzodiazepines, cannabinoids, antidepressants, and several other drug classes. Method performance indicators follow accreditation requirements and include accuracy, precision, measurement uncertainty, calibration models, reportable range, sensitivity, specificity, carryover, interference, ion suppression/enhancement, and analyte stability. "Hands-free" testing platforms require the use of new suspended-state technology to stabilize NIST-traceable standards premanufactured at precise concentrations in the presence of sample preparation reagents. By suspending all reaction components in the solid state, with air gaps between the phases, reference standards and process controls are built in a "ready-to-go" format and stabilized for long-term storage in the presence of a sample matrix, β-d-glucuronidase, and enzymatic buffers. "Hands-free" test kits are removed from storage, incubated at either ambient temperature or 60 °C, and assayed using validated methods. This is the first example of how complex forensic testing workflows can be streamlined with new "hands-free" testing strategies to meet analytical challenges associated with quantitative and confirmatory analyses.

Abstract
Cannabis, cocaine, 3,4-methylenedioxymethamphetamine, and lysergic acid diethylamide are psychoactive substances with a significant increase in consumption during the 21st century due to their popularity in medicinal and recreational use. New psychoactive substances (NPSs) mimic established psychoactive substances. NPSs are known as being natural and safe to consumers; however, they are neither natural nor safe, causing severe adverse reactions, including seizures, nephrotoxicity, and sometimes death. Synthetic cannabinoids, synthetic cathinones, phenethylamines, and piperazines are all examples of NPSs. As of January 2020, nearly 1000 NPSs have become documented. Due to their low cost, ease of availability, and difficulty of detection, misuse of NPSs has become a familiar and growing problem, especially in adolescents and young adults in the past decade. The use of NPSs is associated with higher risks of unplanned sexual intercourse and pregnancy. As many as 4 in 100 women seeking treatment for substance abuse are pregnant or nursing. Animal studies and human clinical case reports have shown that exposure to certain NPSs during lactation periods has toxic effects on neonates, increasing various risks, including brain damage. Nevertheless, neonatal toxicity effects of NPSs are usually unrecognized and overlooked by healthcare professionals. In this review article, we introduce and discuss the potential neonatal toxicity of NPSs, emphasizing synthetic cannabinoids. Utilizing the established prediction models, we identify synthetic cannabinoids and their highly accumulative metabolites in breast milk.

Emerg Med Australas 2023; 35:25-33. [PMID: 35859101 DOI: 10.1111/1742-6723.14040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Revised: 06/09/2022] [Accepted: 06/12/2022] [Indexed: 01/19/2023]
Abstract
OBJECTIVE The aim of the present study was to obtain an unbiased understanding of the prevalence of psychoactive drugs in trauma patients presenting to a large ED. METHODS Consecutive adult patients presenting to the ED with an injury resulting in a trauma call had an anonymised, additional blood test taken for detection of over 2000 drugs. Laboratory testing was to judicial standards. Drugs given by ambulance pre-hospital were detected but excluded from the analysis. RESULTS Over 6 months 276 (74.7%) of 371 patients were tested. Of the 276 patients tested, 158 (57.2%) had one or more psychoactive drug present. Recreational drugs were detected in 101 (36.6%) patients and medicinal drugs in 88 (31.8%) patients, with a combination of both detected in 31 (11.2%) patients. The most common drugs detected were cannabis (22.1%), antidepressants (18.4%), alcohol (15.5%), opioids (10.1%), benzodiazepine/z-drugs (9.4%) and methamphetamine (7.2%). The prevalence of psychoactive drugs differed by age group, sex and cause of injury. CONCLUSIONS The prevalence of psychoactive drugs in injury presentations to an ED is high, and provides an opportunity to reduce harm. The present study demonstrates the feasibility of an approach which limits bias and obtains results that accurately reflect the drug prevalence in injured cohorts. Systematic testing of injured patients is an important contribution to the epidemiology of injury.

Abstract
BACKGROUND Every year, more new psychoactive substances (NPSs) emerge in the market of the drugs of abuse. NPSs belong to various chemical classes, such as synthetic cannabinoids, phenethylamines, opioids, and benzodiazepines. The detection of NPSs intake using different types of biological matrices is challenging for clinical toxicologists because of their structural diversity and the lack of information on their toxicokinetics, including their metabolic fate. METHODS PubMed-listed articles reporting mass spectrometry-based bioanalytical approaches for NPSs detection published during the past 5 years were identified and discussed. Furthermore, the pros and cons of using common biological matrices in clinical toxicology (CT) settings to screen for NPSs are highlighted in this review article. RESULTS Twenty-six articles presenting multianalyte screening methods for use in the field of CT were considered. The advantages and disadvantages of different biological matrices are discussed with a particular view of the different analytical tasks in CT, especially emergency toxicology. Finally, an outlook introduces the emerging trends in biosamples used in CT, such as the exhaled breath. CONCLUSIONS Blood and urine represent the most common biological matrices used in a CT setting; however, reports concerning NPSs detection in alternative matrices are also available. Noteworthy, the selection of the biological matrix must depend on the clinician's enquiry because the individual advantages and disadvantages must be considered.

Abstract
MDMB-4en-PINACA (Methyl 3,3-dimethyl-2-[1-(pent-4-en-1-yl)-1H-indazole-3-carboxamido] butanoate) is a potent agonist of the CB1 receptor. In 2021, it was one of the most common synthetic cannabinoid receptor agonists (SCRAs) seized by the Beijing Drug Control Agency. MDMB-4en-PINACA can be hard to detect in biological specimens because of ester hydrolysis. In this work, a highly sensitive liquid chromatography-high-resolution mass spectrometry (LC-HRMS) method was developed for the detection of MDMB-4en-PINACA metabolites in urine, serum, and hair samples. Metabolites from authentic samples were compared with those from human liver microsomes (HLMs) in vitro and in zebrafish in vivo. A total of 75 metabolites, including 44 previously unreported metabolites, were identified from urine samples. We found that 11 metabolic pathways were involved in MDMB-4en-PINACA metabolism, including acetylation, a novel metabolic pathway for SCRAs. Our results revealed that ester hydrolysis and hydroxylation were to the major metabolic pathways involved in MDMB-4en-PINACA metabolism. Using serum samples, we detected 9 metabolites along with the parent drug. Only the parent drug was detected using hair samples. The existence of ADB-4en-PINACA makes the currently used biomarkers for MDMB-4enPINACA not very specific for the intake of MDMB-4en-PINACA. Therefore, based on the identified metabolites and their structural features, we propose more sensitive screening tactics for MDMB-4en-PINACA using urine and serum samples.

Detection of the Synthetic Cannabinoids AB-CHMINACA, ADB-CHMINACA, MDMB-CHMICA, and 5F-MDMB-PINACA in Biological Matrices: A Systematic Review. BIOLOGY 2022; 11:biology11050796. [PMID: 35625524 PMCID: PMC9139075 DOI: 10.3390/biology11050796] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 05/13/2022] [Accepted: 05/18/2022] [Indexed: 11/17/2022]
Abstract
Simple Summary Synthetic cannabinoids were originally developed for scientific research and potential therapeutic agents. However, clandestine laboratories synthesize them and circumvent legal barriers by falsely marketing them as incense or herbal products. They have serious adverse effects, and new derivatives are continuously found in the market, making their detection difficult due to the lack of comparative standards. Human matrices are used to identify the type of synthetic cannabinoid and the time of its consumption. This review discusses the use of hair, oral fluid, blood, and urine in the detection and quantification of some of the major synthetic cannabinoids. Based on the results, some recommendations can be followed, for example, the use of hair to detect chronic and retrospective consumption (although sensitive to external contamination) and oral fluid or blood for the simultaneous detection of the parent compounds and their metabolites. If longer detection times than blood or oral fluid are needed, urine is the matrix of choice, although its pH may intervene in the analysis. This work highlights the use of new techniques, such as high-resolution mass spectrometry, to avoid the use of previous standards and to monitor new trends in the drug market. Abstract New synthetic cannabinoids (SCs) are emerging rapidly and continuously. Biological matrices are key for their precise detection to link toxicity and symptoms to each compound and concentration and ascertain consumption trends. The objective of this study was to determine the best human biological matrices to detect the risk-assessed compounds provided by The European Monitoring Centre for Drugs and Drug Addiction: AB-CHMINACA, ADB-CHMNACA, MDMB-CHMICA, and 5F-MDMB-PINACA. We carried out a systematic review covering 2015 up to the present date, including original articles assessing detection in antemortem human biological matrices with detailed validation information of the technique. In oral fluid and blood, SC parent compounds were found in oral fluid and blood at low concentrations and usually with other substances; thus, the correlation between SCs concentrations and severity of symptoms could rarely be established. When hair is used as the biological matrix, there are difficulties in excluding passive contamination when evaluating chronic consumption. Detection of metabolites in urine is complex because it requires prior identification studies. LC-MS/MS assays were the most widely used approaches for the selective identification of SCs, although the lack of standard references and the need for revalidation with the continuous emergence of new SCs are limiting factors of this technique. A potential solution is high-resolution mass spectrometry screening, which allows for non-targeted detection and retrospective data interrogation.

Abstract
Synthetic cannabinoid receptor agonists (SCRAs) are an evolving class of new psychoactive substances found on recreational drug markets worldwide. The indole-containing compound, 5F-MDMB-PICA, is a popular SCRA associated with serious medical consequences, including overdose and hospitalizations. In vitro studies reveal that 5F-MDMB-PICA is a potent agonist at cannabinoid type 1 receptors (CB1), but little information exists regarding in vivo pharmacology of the drug. To this end, we examined the in vitro and in vivo cannabinoid-like effects produced by 5F-MDMB-PICA and related 5F-pentylindole analogs with differing composition of the head group moiety (i.e., 5F-NNEI, 5F-SDB-006, 5F-CUMYL-PICA, 5F-MMB-PICA). In mouse brain membranes, 5F-MDMB-PICA and its analogs inhibited binding to [3H]rimonabant-labeled CB1 and displayed agonist actions in [35S]GTPγS functional assays. 5F-MDMB-PICA exhibited the highest CB1 affinity (Ki = 1.24 nM) and functional potency (EC50 = 1.46 nM), but head group composition markedly influenced activity in both assays. For example, the 3,3-dimethylbutanoate (5F-MDMB-PICA) and cumyl (5F-CUMYL-PICA) head groups engendered high CB1 affinity and potency, whereas a benzyl (5F-SDB-006) head group did not. In C57BL/6J mice, all 5F-pentylindole SCRAs produced dose- and time-dependent hypothermia, catalepsy, and analgesia that were reversed by rimonabant, indicating CB1 involvement. In vitro Ki and EC50 values were positively correlated with in vivo ED50 potency estimates. Our findings demonstrate that 5F-MDMB-PICA is a potent SCRA, and subtle alterations to head group composition can have profound influence on pharmacological effects at CB1. Importantly, measures of CB1 binding and efficacy in mouse brain tissue seem to accurately predict in vivo drug potency in this species.

Abstract
Synthetic cannabinoids (SCs) remain one of the largest groups of new psychoactive substances. Recently, new synthetic cannabinoids 5F-MDMB-PICA and 4F-MDMB-BINACA are increasing in popularity. A 33-year-old man lost consciousness after smoking an unknown substance. A glass pipe and two lumps of substance that turned out to contain 5F-MDMB-PICA and 4F-MDMB-BINACA were found at the scene. Blood, urine and cerebrospinal fluid were collected during the examination of the body. The synthetic cannabinoids were isolated from autopsy materials by precipitation with acetonitrile and extraction with ethyl acetate. The screening and quantitative analyses were performed by liquid chromatography with tandem mass spectrometry (LC-MS/MS). The liquid chromatography-quadrupole/time of flight mass spectrometry (LC-Q/TOF) technique was used for metabolite identification. 5F-MDMB-PICA was detected and quantified in all analysed materials, whereas 4F-MDMB-BINACA was found only in cerebrospinal fluid. The determined concentrations of 5F-MDMB-PICA were 0.9 (blood), 0.1 (urine) and 3.2 ng/mL (cerebrospinal fluid). The concentration of 4F-MDMB-BINACA in cerebrospinal fluid was 0.1 ng/mL. The main metabolites of both compounds (hydrolysis and oxidative defluorination) were found in all analysed body fluids. Cerebrospinal fluid may be important alternative material in autopsy cases. Rapid elimination of 5F-MDMB-PICA and 4F-MDMB-BINACA compounds also means that the metabolite analysis can be crucial for the investigation. Laboratories must be made aware of their presence and incorporate these SCs and their metabolites into workflows for detection and confirmation. Ester hydrolysis and oxidative defluorination products can be found in blood, urine and cerebrospinal fluid making them useful biomarkers of intake.

Abstract
Recreational use of Synthetic Cannabinoids (SCs), one of the largest groups of New Psychoactive Substances (NPS), has increased globally over the past few years. Driving is a structured process requiring the cooperation of several cognitive and psychomotor functions, organized in different levels of complexity. Each of these functions can be affected when Driving Under the Influence (DUI) of SCs. In order to reduce the likelihood of SC-related road accidents, it is essential to understand which areas of psychomotor performance are most affected by these substances, as well as the severity of impairment. For this purpose, a multiple database- literature review of recent experimental studies in humans and animals regarding the psychomotor effects of SCs has been performed. Despite the many limitations connected to experimental studies on humans, results showed a consistency between animal and human data. SCs appear to impair psychomotor performance in humans, affecting different domains related to safe driving even at low doses. Cases of DUI of SC have been repeatedly reported, although the exact prevalence is likely to be underestimated due to current analytical and interpretative issues. For this reason, an accurate physical examination performed by trained and experienced personnel has a primary role in recognizing signs of impairment in case of strong suspicion of SC consumption. The identification of a suspected case should be followed by reliable laboratory examination.

Application of a UPLC-MS/MS method for quantitative analysis of 29 synthetic cannabinoids and their metabolites, such as ADB-BUTINACA and MDMB-4en-PINACA in human hair in real cases. Forensic Sci Int 2021; 331:111139. [PMID: 34922285 DOI: 10.1016/j.forsciint.2021.111139] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 11/22/2021] [Accepted: 12/02/2021] [Indexed: 11/21/2022]
Abstract
In recent years, an increasing number of new synthetic cannabinoids have appeared on the drug trade market. Many of the new synthetic cannabinoids have not previously been reported. At present, there are relatively few methods available for detecting synthetic cannabinoids and their metabolites in hair matrices. Therefore, we established a simple and fast method to simultaneously identify 29 synthetic cannabinoids and their metabolites in human hair by UPLC-MS/MS. Twenty milligrams of hair was used and processed by cryo-grinding and extraction with methanol. A Waters Acquity UPLC HSS T3 column (100 mm × 2.1 mm, 1.8 µm) was used for chromatographic separation. Mobile phase A was comprised of 20 mmol/L ammonium acetate, 0.1% formic acid, and 5% acetonitrile and water, and mobile phase B was acetonitrile. The method was fully validated and proved to have good selectivity, accuracy, precision, and satisfactory linearity within the calibrated range. The limit of detection (LOD) ranged from 0.5 to 5 pg/mg, and the lower limit of quantitation (LLOQ) ranged from 1 to 10 pg/mg. The extraction recovery was 36.1-93.3%, and the matrix effect was 19.1-110.0%. The validated method was successfully used to qualitatively and quantitatively analyze 29 synthetic cannabinoids and their metabolites in 59 actual hair samples. MDMB-4en-PINACA had the highest positive detection rate followed by ADB-BUTINACA, and there are multiple synthetic cannabinoid mixed ingestions. This methodology has great potential for the detection of 29 synthetic cannabinoids and their metabolites in forensic cases.

Abstract
In the last few years, liquid chromatography coupled with mass spectrometry (LC/MS) has been increasingly used for screening purposes in forensic toxicology. These techniques have the advantages of low time/resource-consuming and high versatility and have been applied in numerous new multi-analytes methods. The new psychoactive substance (NPS) phenomenon provided a great impulse to this wide-range approach, but it is also important to keep the attention on “classical” psychoactive substances, such as benzodiazepines (BDZ). In this paper, a fully validated screening method in blood for the simultaneous detection of 163 substances (120 NPS and 43 other drugs) by a dynamic multiple reaction monitoring analysis through LC-MS/MS is described. The method consists of a deproteinization of 200 µL of blood with acetonitrile. The LC separation is achieved with a 100 mm long C18 column in 35 min. The method was very sensitive, with limits of quantification from 0.02 to 1.5 ng/mL. Matrix effects did not negatively affect the analytical sensitivity. This method proved to be reliable and was successfully applied to our routinary analytical activity in several forensic caseworks, allowing the identification and quantification of many BDZs and 3,4-methylenedioxypyrovalerone (MDPV).

Abstract
The use of cannabidiol (CBD), the non-psychotropic compound derived from Cannabis sativa, for therapeutic purposes is growing exponentially by targeting the management of multiple medical disorders, including metabolic-related diseases. Nevertheless, substantial questions have emerged in concerning the potential metabolic disturbances in adulthood as consequence of the long-term uses of CBD during early years of life. Therefore, we studied whether chronic CBD injections (5, 10 or 30 mg/kg; i.p.) given to juvenile rats (from post-natal day [PND] 30) for 14 days might influence in adulthood the activity of metabolic markers, such as glucose, total cholesterol, triglycerides as well as activity of antioxidants (DPPH) from plasma, white adipose tissue (WAT), brown adipose tissue (BAT), liver, and hypothalamus. Our results showed that adult rats treated during juvenile ages with CBD (5, 10 or 30 mg/kg) for two weeks increased the contents of glucose whereas with no changes on total cholesterol in adulthood were observed. Additionally, a significant decrease in the levels of triglycerides were found in plasma, WAT, BAT, and liver in adult rats treated with chronic injections of CBD during the adolescence. However, unexpectedly, the contents of triglycerides in hypothalamus were found enhanced. Finally, the DPPH assay showed a significant enhancement in triglycerides analyzed from WAT and liver whereas opposite findings were observed in BAT and no significant changes were found in hypothalamus in adult rats that received during the adolescence chronic injections of CBD. In conclusion, repeated CBD administration to juvenile rats induced significant alterations in multiple metabolic markers analyzed in the adulthood. Our findings highlight the relevance of chronic CBD treatment in disturbed metabolic activity and remark the need for studying the underlying mechanisms involved.

Abstract
Introduction The analysis of novel psychoactive substances (NPS) represents a challenge in forensic toxicology, due to the high number of compounds characterized by different structures and physicochemical properties both among different subclasses and within a single subclass of NPS. The aim of the present work is the development and validation of a targeted liquid chromatography tandem mass spectrometry (LC‐MS/MS) method for the detection of NPS in whole blood. Materials and methods A protein‐precipitation based LC‐MS/MS method for the detection of more than 180 NPS was developed and validated by assessing the following parameters: selectivity, linearity, accuracy, precision, limit of detection (LOD) and of quantification (LOQ) recovery, and matrix effect. Then, the method was applied to real forensic samples. Results The method allowed the identification of 132 synthetic cannabinoids, 22 synthetic opioids, and 28 substances among synthetic cathinones, stimulants, and other drugs. Validation was successfully achieved for most of the compounds. Linearity was in the range of 0.25–10 ng/ml for synthetic cannabinoids and 0.25–25 ng/ml for other drugs. Accuracy and precision were acceptable according to international guidelines. Three cases tested positive for fentanyl and ketamine, in the setting of emergency room administration. Conclusions The present methodology represents a fast, not expensive, wide‐panel method for the analysis of more than 180 NPS by LC‐MS/MS, which can be profitably applied both in a clinical context and in postmortem toxicology.

Abstract
An ever-increasing need exists within the forensic laboratories to develop analytical processes for the qualitative and quantitative determination of a broad spectrum of new psychoactive substances. Phenylethylamine derivatives are among the major classes of psychoactive substances available on the global market and include both amphetamine analogues and synthetic cathinones. In this work, an ultra-high-performance liquid chromatography-positive ion electrospray ionization tandem mass spectrometric method (UHPLC-ESI-MS/MS) has been developed and fully validated for the determination of 19 psychoactive substances, including nine amphetamine-type stimulants and 10 synthetic cathinone derivatives, in premortem and postmortem whole blood. The assay was based on the use of 1 mL premortem or postmortem whole blood, following solid phase extraction prior to the analysis. The separation was achieved on a Poroshell 120 EC-C18 analytical column with a gradient mobile phase of 0.1% formic acid in acetonitrile and 0.1% formic acid in water in 9 min. The dynamic multiple reaction monitoring used in this work allowed for limit of detection (LOD) and lower limit of quantitation (LOQ) values of 0.5 and 2 ng mL−1, respectively, for all analytes both in premortem and postmortem whole blood samples. A quadratic calibration model was used for the 12 quantitative analytes over the concentration range of 20–2000 ng mL−1, and the method was shown to be precise and accurate both in premortem and postmortem whole blood. The method was applied to the analysis of real cases and proved to be a valuable tool in forensic and clinical toxicology.

Abstract
A procedure has been developed for the determination of third-generation synthetic cannabinoids in oral fluid samples by using a semi-automated microextraction by packed sorbent (MEPS) procedure and gas chromatography-mass spectrometry (GC-MS) determination. Five synthetic cannabinoids were employed as model compounds 5F-ADB, MMB-CHMICA, THJ-2201, CUMYL-4CN-BINACA and MDMB-CHMCZCA. The most adequate operative conditions for MEPS were evaluated giving quantitative recoveries, from 89 to 124%, in synthetic and field saliva samples spiked with 125 and 250 μg/L of the studied cannabinoids, with the exception of MDMB-CHMCZCA in field saliva samples that provided slightly lower recoveries from 62 to 66%. A high sensitivity was obtained for the proposed MEPS-GC-MS procedure with limits of detection from 10 to 20 μg/L. The obtained results demonstrate the high potential of MEPS-GC-MS combination for semi-automated, selective and sensitive determination of synthetic cannabinoids in oral fluid samples.

Abstract
In 2020, 5F-MDMB-PICA (5F-MDMB-2201) was one of the most common synthetic cannabinoids (SCs) identified in drugs seized by the Beijing Drug Control Agency and it was categorized as Schedule II by the United Nations Office on Drugs and Crime (UNODC) in March 2020. It is difficult to detect 5F-MDMB-PICA in biological matrices due to its fast metabolic rate in vivo. In this work, 5F-MDMB-PICA metabolic profiles were investigated by liquid chromatography-Q Exactive HF Hybrid Quadrupole-Orbitrap mass spectrometry (LC-QE-HF-MS), with accurate mass measurements in human urine, serum, and pubic hair. To obtain intact metabolites, solid-phase extraction (SPE) for urine and serum and direct ultrasonic extraction for pubic hair were applied to clean the samples without enzymatic hydrolysis. The differences in 5F-MDMB-PICA metabolism in the three different matrices were compared for the first time to determine the best detection biomarkers for monitoring 5F-MDMB-PICA misuse. Urine samples were determined to be the preferred biological material for identifying 5F-MDMB-PICA abuse. Forty-seven intact metabolites were detected in human urine, the ester-hydrolyzed with glucuronidated metabolite in urine samples can be used as the primary biomarker to identify drug misuse. Fifteen metabolites were found in serum samples. Ester hydrolysis was considered to be the major metabolic pathway, and a large number of metabolites were involved with it. Zero metabolites apart from the parent drug were detected in pubic hair samples. Twenty-eight new metabolites and their metabolic pathways were characterized and tentatively identified by LC-QE-HF-MS, and a new potential biomarker (M5 Ester hydrolysis + propionic acid) was also identified.

Overview of Synthetic Cannabinoids ADB-FUBINACA and AMB-FUBINACA: Clinical, Analytical, and Forensic Implications. Pharmaceuticals (Basel) 2021; 14:ph14030186. [PMID: 33669071 PMCID: PMC7996508 DOI: 10.3390/ph14030186] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 02/19/2021] [Accepted: 02/20/2021] [Indexed: 01/08/2023] Open
Abstract
ADB-FUBINACA and AMB-FUBINACA are two synthetic indazole-derived cannabinoid receptor agonists, up to 140- and 85-fold more potent, respectively, than trans-∆9-tetrahydrocannabinol (∆9-THC), the main psychoactive compound of cannabis. Synthesised in 2009 as a pharmaceutical drug candidate, the recreational use of ADB-FUBINACA was first reported in 2013 in Japan, with fatal cases being described in 2015. ADB-FUBINACA is one of the most apprehended and consumed synthetic cannabinoid (SC), following AMB-FUBINACA, which emerged in 2014 as a drug of abuse and has since been responsible for several intoxication and death outbreaks. Here, we critically review the physicochemical properties, detection methods, prevalence, biological effects, pharmacodynamics and pharmacokinetics of both drugs. When smoked, these SCs produce almost immediate effects (about 10 to 15 s after use) that last up to 60 min. They are rapidly and extensively metabolised, being the O-demethylated metabolite of AMB-FUBINACA, 2-(1-(4-fluorobenzyl)-1H-indazole-3-carboxamide)-3-methylbutanoic acid, the main excreted in urine, while for ADB-FUBINACA the main biomarkers are the hydroxdimethylpropyl ADB-FUBINACA, hydroxydehydrodimethylpropyl ADB-FUBINACA and hydroxylindazole ADB-FUBINACA. ADB-FUBINACA and AMB-FUBINACA display full agonism of the CB1 receptor, this being responsible for their cardiovascular and neurological effects (e.g., altered perception, agitation, anxiety, paranoia, hallucinations, loss of consciousness and memory, chest pain, hypertension, tachycardia, seizures). This review highlights the urgent requirement for additional studies on the toxicokinetic properties of AMB-FUBINACA and ADB-FUBINACA, as this is imperative to improve the methods for detecting and quantifying these drugs and to determine the best exposure markers in the various biological matrices. Furthermore, it stresses the need for clinicians and pathologists involved in the management of these intoxications to describe their findings in the scientific literature, thus assisting in the risk assessment and treatment of the harmful effects of these drugs in future medical and forensic investigations.

Abstract
Abstract
The misuse of psychoactive substances is attracting a great deal of attention from the general public. An increase use of psychoactive substances is observed among young people who do not have enough awareness of the harmful effects of these substances. Easy access to illicit drugs at low cost and lack of effective means of routine screening for new psychoactive substances (NPS) have contributed to the rapid increase in their use. New research and evidence suggest that drug use can cause a variety of adverse psychological and physiological effects on human health (anxiety, panic, paranoia, psychosis, and seizures). We describe different classes of these NPS drugs with emphasis on the methods used to identify them and the identification of their metabolites in biological specimens. This is the first review that thoroughly gives the literature on both natural and synthetic illegal drugs with old known data and very hot new topics and investigations, which enables the researcher to use it as a starting point in the literature exploration and planning of the own research. For the first time, the conformational analysis was done for selected illegal drugs, giving rise to the search of the biologically active conformations both theoretically and using lab experiments.

Abstract
Frustration at the restrictions to access prescribed cannabinoids in New Zealand has resulted in a black market of home-made cannabis-based products for medicinal use. These products are being made, and marketed illegally, by individuals calling themselves ‘Green Fairies’. The products take many forms and are being used to treat a range of illnesses and symptoms including pain, insomnia, anxiety, and seizures. Analytical extraction methods were developed to determine the cannabinoid content in a variety of matrices, principally those that are soluble in methanol and those that are soluble in hexane. An LC-MS/MS method was developed that detected THC, THCA, CBD, CBDA, CBG, CBGA, CBN, THCV, and CBC with lower detection limits around 0.001mg of cannabinoid per gram (mgg−1) of product. One hundred ‘Green Fairy’ samples have been analysed to determine the cannabinoid content, including 12 fully extracted cannabis oil (FECO) samples, 12 ethanolic tinctures, 6 vape juices, 39 oily liquids with olive oil, hemp seed oil, or medium chain triglycerides (MCT) as a base, and 31 waxy solids made using coconut oil. Nine named cannabis plant cultivars purported to be used to make these products have also been analysed. The results of the analyses show that these Green Fairy products contain a wide range of cannabinoid concentrations and the claim that a product was high in CBD was often not correct. The proposed dose size was not specified for these products, but few would provide what is considered an effective dose when compared with the administration of commercially purified cannabinoid products available by prescription. For many products the manufacturer had specified which cannabis cultivar had been used but a comparison of cannabinoid ratios showed a lack of consistency within products said to be made from the same strain. Analysis of named cannabis cultivars available showed little variation in the relative amounts of THC and CBD.

Abstract
RATIONALE Indazole carboxamide synthetic cannabinoids, a prevalent class of recreational drugs, are a major clinical, forensic and public health challenge. One such compound, 5F-ADB, has been implicated in fatalities worldwide. Understanding its metabolism and distribution facilitates the development of laboratory assays to substantiate its consumption. Synthetic cannabinoid metabolites have been extensively studied in urine; studies identifying metabolites in blood are limited and no data on the metabolic stability (half-life, clearance and extraction ratio) of 5F-ADB have been published prior to this report. METHODS The in vitro metabolism of 5F-ADB was elucidated via incubation with human liver microsomes for 2 h at 37°C. Samples were collected at multiple time points to determine its metabolic stability. Upon identification of metabolites, authentic forensic human blood samples underwent liquid-liquid extraction and were screened for metabolites. Extracts were analyzed via ultra-high-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UHPLC/QTOFMS) operated in positive electrospray ionization mode. RESULTS Seven metabolites were identified including oxidative defluorination (M1); carboxypentyl (M2); monohydroxylation of the fluoropentyl chain (M3.1/M3.2) and indazole ring system (M4); ester hydrolysis (M5); and ester hydrolysis with oxidative defluorination (M6). The half-life (3.1 min), intrinsic clearance (256.2 mL min-1 kg-1 ), hepatic clearance (18.6 mL min-1 kg-1 ) and extraction ratio (0.93) were determined for the first time. In blood, M1 was present in each sample as the most abundant substance; two samples contained M5; one contained 5F-ADB, M1 and M5. CONCLUSIONS 5F-ADB is rapidly metabolized in HLM. 5F-ADB, M1 and M5 are pharmacologically active at the cannabinoid receptors (CB1 /CB2 ) and M1 and M5 may contribute to a user's impairment profile. The results demonstrate that it is imperative that synthetic cannabinoid assays screen for pharmacologically active metabolites, especially for drugs with short half-lives. The authors propose that M1 and M5 are appropriate markers to include in laboratory blood tests screening for 5F-ADB.

Abstract
One of the problems associated with the consumption of new psychoactive substances is that in most scenarios of acute toxicity the possibility of quick clinical action may be impaired because many screening methods are not responsive to them, and laboratories are not able to keep pace with the appearance of new substances. For these reasons, developing and validating new analytical methods is mandatory in order to efficiently face those problems, allowing laboratories to be one step ahead. The goal of this work is to perform a critical review regarding bionalytical methods that can be used for the determination of new psychoactive substances (phenylethylamines, cathinones, synthetic cannabinoids, opioids, benzodiazepines, etc), particularly concerning sample preparation techniques and associated analytical methods.

Assessment of synthetic cannabinoid FUB-AMB and its ester hydrolysis metabolite in human liver microsomes and human blood samples using UHPLC-MS/MS. Biomed Chromatogr 2020; 34:e4884.

Abstract
FUB-AMB, an indazole carboxamide synthetic cannabinoid recreational drug, was one of the compounds most frequently reported to governmental agencies worldwide between 2016 and 2019. It has been implicated in intoxications and fatalities, posing a risk to public health. In the current study, FUB-AMB was incubated with human liver microsomes (HLM) to assess its metabolic fate and stability and to determine if its major ester hydrolysis metabolite (M1) was present in 12 authentic forensic human blood samples from driving under the influence of drug cases and postmortem investigations using UHPLC-MS/MS. FUB-AMB was rapidly metabolized in HLM, generating M1 that was stable through a 120-min incubation period, a finding that indicates a potential long detection window in human biological samples. M1 was identified in all blood samples, and no parent drug was detected. The authors propose that M1 is a reliable marker for inclusion in laboratory blood screens for FUB-AMB; this metabolite may be pharmacologically active like its precursor FUB-AMB. M1 frequently appears in samples in which the parent drug is undetectable and can point to the causative agent. The results suggest that it is imperative that synthetic cannabinoid laboratory assay panels include metabolites, especially known or potential pharmacologically active metabolites, particularly for compounds with short half-lives.

Cannabis et cannabinoïdes de synthèse. À propos de leur détection biologique. BULLETIN DE L'ACADÉMIE NATIONALE DE MÉDECINE 2020; 204:577-582.

Abstract
Parmi la soixantaine de cannabinoïdes présents dans le cannabis sativa indica on trouve essentiellement des terpénophénols, parmi lesquels figure le delta-9-trans tétrahydrocannabinol (Δ9-THC) qui constitue le principal produit psychoactif chez l’homme. Depuis une dizaine d’années, avec l’émergence du e-commerce et la recherche pharmaceutique sur des médicaments originaux, des dérivés synthétiques du Δ9-THC ont fait leur apparition. Ces molécules, sous le nom générique anglo-saxon de « spices », ont des structures chimiques très différentes, mais se lient toutes sur les mêmes récepteurs CB1 et CB2. Elles miment les effets du Δ9-THC, avec des effets pharmacologiques plus puissants, et donc des effets secondaires bien plus délétères et des durées d’action augmentées. L’usage de tous les cannabinoïdes est contrôlé, ce qui nécessite de disposer de méthodes analytiques performantes pour leur détection. L’objet de cette mini revue est de faire le point sur les possibilités actuelles de mise en évidence et de discuter, en fonction de la matrice biologique utilisée (sang, urine, salive, sueur, air expiré, cheveux) des avantages et des limitations de chaque approche.
