Oral fluid analysis to monitor recent exposure to synthetic cannabinoids in a high-risk subpopulation. J Forensic Sci 2022; 67:1932-1937.

Abstract
Among novel psychoactive substances, synthetic cannabinoid receptor agonists (SCRA) seem to have the widest diffusion in the population with no limitation to any particular demographic group. Information on drug consumption relies mostly on anonymized surveys and less on clinical or analytical data; notwithstanding, the huge efforts constantly made to enroll subjects to gather epidemiological data. In the present study, we collected 66 oral fluid samples from volunteers in a drug rehabilitation center in 2019 and early 2020. A liquid chromatography-mass spectrometry method previously developed and validated by our Unit was applied to detect SCRA (n = 10) in oral fluid. Results proved the presence of synthetic cannabinoids at a positivity rate of almost 20%, with detection frequency HU211(5/13) > UR144/JWH122 (3/13) > JWH019/JWH081/AM2201 (1/13). Concentrations were in the range < LOQ -0.36 ng/ml. Synthetic cannabinoids consumption had not been declared by any volunteer. This study enabled for the unprecedent detection of synthetic cannabinoids use in the territory of Parma (Italy) in a high-risk subpopulation. The identified SCRA proved the persistence into the market of the "first-generation" JWH family into the Italian territory and the marketing of relatively new ones (AM-2201). Public health consequences represented by NPS consumption are still scarce; therefore, further studies are needed to understand the real diffusion in the population.

Oliveira MN, Gonçalves OC, Ahmad SM, Schneider JK, Krause LC, Neng NR, Caramão EB, Nogueira JMF. Application of Bar Adsorptive Microextraction for the Determination of Levels of Tricyclic Antidepressants in Urine Samples. Molecules 2021; 26:3101. [PMID: 34067333 PMCID: PMC8196885 DOI: 10.3390/molecules26113101] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 05/15/2021] [Accepted: 05/18/2021] [Indexed: 11/29/2022] Open
Abstract
This work entailed the development, optimization, validation, and application of a novel analytical approach, using the bar adsorptive microextraction technique (BAμE), for the determination of the six most common tricyclic antidepressants (TCAs; amitriptyline, mianserin, trimipramine, imipramine, mirtazapine and dosulepin) in urine matrices. To achieve this goal, we employed, for the first time, new generation microextraction devices coated with convenient sorbent phases, polymers and novel activated carbons prepared from biomaterial waste, in combination with large-volume-injection gas chromatography-mass spectrometry operating in selected-ion monitoring mode (LVI-GC-MS(SIM)). Preliminary assays on sorbent coatings, showed that the polymeric phases present a much more effective performance, as the tested biosorbents exhibited low efficiency for application in microextraction techniques. By using BAμE coated with C18 polymer, under optimized experimental conditions, the detection limits achieved for the six TCAs ranged from 0.2 to 1.6 μg L-1 and, weighted linear regressions resulted in remarkable linearity (r2 > 0.9960) between 10.0 and 1000.0 μg L-1. The developed analytical methodology (BAμE(C18)/LVI-GC-MS(SIM)) provided suitable matrix effects (90.2-112.9%, RSD ≤ 13.9%), high recovery yields (92.3-111.5%, RSD ≤ 12.3%) and a remarkable overall process efficiency (ranging from 84.9% to 124.3%, RSD ≤ 13.9%). The developed and validated methodology was successfully applied for screening the six TCAs in real urine matrices. The proposed analytical methodology proved to be an eco-user-friendly approach to monitor trace levels of TCAs in complex urine matrices and an outstanding analytical alternative in comparison with other microextraction-based techniques.

Acute Pharmacological Effects and Oral Fluid Biomarkers of the Synthetic Cannabinoid UR-144 and THC in Recreational Users. BIOLOGY 2021; 10:257. [PMID: 33805054 PMCID: PMC8064062 DOI: 10.3390/biology10040257] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 03/21/2021] [Accepted: 03/22/2021] [Indexed: 01/08/2023]
Abstract
Synthetic cannabinoids (SCs) are one of the most frequent classes of new psychoactive substances monitored by the EU Early Warning System and World Health Organization. UR-144 is a SC with a relative low affinity for the CB1 receptor with respect to that for the CB2 receptor. As with other cannabinoid receptor agonists, it has been monitored by the EU Early Warning System since 2012 for severe adverse effects on consumers. Since data for UR-144 human pharmacology are very limited, an observational study was carried out to evaluate its acute pharmacological effects following its administration using a cannabis joint as term of comparison. Disposition of UR-144 and delta-9-tetrahydrocannibinol (THC) was investigated in oral fluid. Sixteen volunteers smoked a joint prepared with tobacco and 1 or 1.5 mg dose of UR-144 (n = 8) or cannabis flowering tops containing 10 or 20 mg THC (n = 8). Physiological variables including systolic and diastolic blood pressure, heart rate and cutaneous temperature were measured. A set of Visual Analog Scales (VAS), the Addiction Research Centre Inventory (ARCI)-49-item short form version and the Evaluation of the Subjective Effects of Substances with Abuse Potential (VESSPA-SSE) were administered to evaluate subjective effects. Oral fluid was collected at baseline, 10, 20, 40 min and 1, 2, 3 and 4 h after smoking, for UR-144 or THC concentration monitoring. Results showed significant statistical increases in both systolic and diastolic blood pressure and heart rate after both UR-144 and cannabis smoking. Both substances produced an increase in VAS related to stimulant-like and high effects, but scores were significantly higher after cannabis administration. No hallucinogenic effects were observed. Maximal oral fluid UR-144 and THC concentrations appeared at 20 and 10 min after smoking, respectively. The presence of UR-144 in oral fluid constitutes a non-invasive biomarker of SC consumption. The results of this observational study provide valuable preliminary data of the pharmacological effects of UR-144, showing a similar profile of cardiovascular effects in comparison with THC but lower intensity of subjective effects. Our results have to be confirmed by research in a larger sample to extensively clarify pharmacological effects and the health risk profile of UR-144.

Determination of the Synthetic Cannabinoids JWH-122, JWH-210, UR-144 in Oral Fluid of Consumers by GC-MS and Quantification of Parent Compounds and Metabolites by UHPLC-MS/MS. Int J Mol Sci 2020; 21:ijms21249414.

Abstract
The consumption of synthetic cannabinoids (SCs) has significantly increased in the last decade and the analysis of SCs and their metabolites in human specimens is gaining interest in clinical and forensic toxicology. A pilot study has been carried out using a combination of an initial last generation gas chromatography-mass spectrometry (GC-MS) screening method for the determination of JWH-122, JWH-210, UR-144) in oral fluid (OF) of consumers and an ultra-high performance liquid chromatography high resolution mass spectrometry (UHPLC-HRMS) confirmatory method for the quantification of the parent compounds and their metabolites in the same biological matrix. OF samples were simply liquid-liquid extracted before injecting in both chromatographic systems. The developed methods have been successfully validated and were linear from limit of quantification (LOQ) to 50 ng/mL OF. Recovery of analytes was always higher than 70% and matrix effect always lower than 15% whereas intra-assay and inter-assay precision and accuracy were always better than 16%. After smoking 1 mg JWH-122 or UR-144 and 3 mg JWH-210, maximum concentration of 4.00-3.14 ng/mL JWH-122, 8.10-7.30 ng/mL JWH-210 ng/mL and 7.40 and 6.81 ng/mL UR-144 were measured by GC-MS and UHPLC-HRMS respectively at 20 min after inhalation. Metabolites of JWH 122 and 210 were quantified in OF by UHPLC-HRMS, while that of UR144 was only detectable in traces. Our results provide for the first time information about disposition of these SCs and their metabolites in consumers OF. Last generation GC-MS has proven useful tool to identify and quantify parent SCs whereas UHPLC-HRMS also confirmed the presence of SCs metabolites in the OF of SCs consumers.

Comprehensive analysis of synthetic cannabinoids and metabolites in oral fluid by online solid-phase extraction coupled to liquid chromatography-triple quadrupole-mass spectrometry. Anal Bioanal Chem 2020; 412:7937-7953.

Abstract
The class of novel psychoactive substances known as synthetic cannabinoids (SC) includes illicit compounds that are sprayed on plant material and smoked or sold as liquids to be vaporized in e-cigarettes. In toxicological analysis of SC, fast analytical methods are needed for the detection and confirmation of parent drugs and metabolites at very low levels. While various analytical methods have been developed for SC in blood and urine, few are available for alternative matrices such as oral fluid (OF). There are numerous advantages to using OF as a sample matrix for SC analysis, including non-invasive collection, lesser risk of adulteration, and presence of both parent drug and metabolites. Here we report a validated online solid-phase extraction (online SPE) method coupled to LC-QqQ-MS for rapid confirmation and quantitation of 72 structurally diverse SC parent drugs and metabolites in OF with 2.5 min of preconcentration time and a total elution time of < 10 min. The use of online SPE for sample pretreatment facilitates rapid and consistent processing and greatly increases sample throughput. The method was fully validated according to relevant guidelines (ANSI/ASB Standard 036). Bias and precision values were within ± 20% for all compounds in human OF matrix. Method detection and quantitation limits ranged from 0.4 to 3.8 ng/mL and from 1.1 to 11.6 ng/mL, respectively. Recovery, matrix effects, process efficiency, carryover, and stability were also within acceptable limits for the majority of compounds. Successful application of the method was demonstrated using blank human OF fortified with SC in addition to a set of authentic OF specimens previously tested by another laboratory.

Abstract
Synthetic cannabinoids (SCs), mimicking the psychoactive effects of cannabis, consist of a vast array of structurally diverse compounds. A novel compound belonging to the SC family, (1-(cyclohexylmethyl)-1H-indol-3-yl)-(2,2,3,3-tetramethylcyclopropyl)methanone (named TMCP-CHM in this article) contains a cyclopropane ring that isomerizes during the smoking process, resulting in a ring-opened thermal degradant with a terminal double bond in its structure. Metabolites of TMCP-CHM were tentatively identified in vitro (after incubation of the parent substance with S9 pooled human liver fraction) and in vivo (rat experimental model) studies by accurate-mass liquid chromatography-tandem mass spectrometry (LC-MS/MS). For the identification of the degradant metabolites, and to study biotransformation of parent substance in the human, urine and hair samples from patients, who had ingested the compound and were subsequently admitted to hospital with drug intoxications, were analyzed. Products of mono-, di-, trihydroxylation, carboxylation, and carboxylation combined with hydroxylation of TMCP-CHM and its degradant were detected in human urine. Metabolism of the degradant included addition of water to the terminal double bond followed by dehydration and formation of a cyclic metabolite. Degradant metabolites prevailed in comparison with metabolites of the parent substance in each metabolite group examined, except carboxylation. N-Dealkylated metabolites found in human urine originated only from the degradant. Most of the hydroxy metabolites were detected in human urine in both the free form and as glucuronides. The detection of monohydroxylated (M1.1-M1.3, M/A1.10) and carboxylated/hydroxylated (M4.2, M/A4.3) metabolites of TMCP-CHM and the hydrated form of the monohydroxylated metabolite of the degradant was found to be convenient for routine analysis.

Abstract
Workplace drug testing in Australia is governed by two standards AS/NZS 4308:2008 for testing in urine and AS 4760:2006 for oral fluid. These standards are prescriptive and describe the drugs tested, procedures for analysis and collection devices. However, the drugs listed are not exhaustive and workers may consume novel psychoactive substances without detection. Here we present a validated method for the detection and quantitation of 19 synthetic cannabinoids in oral fluid. These drugs are AM2233, JWH-200, AB-005, AB-FUBINACA, AB-PINACA, AB-CHMINACA, AM2201, RCS-4, JWH-250, STS-135, JWH-73, XLR-11, JWH-251, JWH-18, JWH-122, JWH-19, UR-144, JWH-20 and AKB-48. The sample volume is 100 μL and is subject to a rapid, simple, protein precipitation step prior to centrifugation and injection into the LC-MS/MS system. Chromatographic separation was achieved in 4 min on a Kinetex Biphenyl column (50 mm × 3 mm × 2.6 μm) using 0.1% formic acid in water and acetonitrile as the mobile phase. The method was validated with a limit of detection (1 ng/mL) limit of quantitation (2.5 ng/mL), selectivity, linearity (2.5-500 ng/mL), accuracy (90.5-112.5% of the target concentration) and precision (3-14.7%). This method provides for the rapid detection of synthetic cannabinoids in oral fluid which is readily applicable to a routine laboratory.

Abstract
In this work, we propose an innovative high throughput (HT) apparatus using the bar adsorptive microextraction (BAμE) technique, which enables the simultaneous enrichment of up to 100 samples. This novel configuration was combined with microliquid desorption and high-performance liquid chromatography-diode array detection to monitor trace levels of eight benzodiazepines (diazepam, prazepam, bromazepam, oxazepam, lorazepam, alprazolam, temazepam and loflazepate) in biological samples. The proposed methodology was fully developed, optimized and validated, resulting in suitable intraday and interday precision (RSD ≤ 15%), with recovery yields ranging from 33.0% to 104.5%. The lower limits of quantification were between 20.0 and 100.0 µg L-1, using 1.0 mL of urine and 0.5 mL of plasma or serum samples. The application of the proposed methodology to real matrices resulted in average sample preparation time of around 2 min per sample, demonstrating that it is user-friendly, cost-effective and a rapid decision-making tool, whenever large number of samples are involved.

Abstract
Synthetic cannabinoids are a new class of chemical drugs capable of modifying human behavior. These products do not contain cannabis, but produce similar effects after consumption. The fact that they are easily accessed, and are many times considered to be harmless, justifies their widespread use among young people. This fact, together with the difficulty in their detection by routine drug tests, makes it extremely important to develop new procedures able to detect and monitor their consumption. The aim of this work is to perform a critical review regarding the human biological samples that can be used for the determination of synthetic cannabinoids, paying special attention to analytical methods and sample preparation techniques. The reviewed articles deal with the determination of synthetic cannabinoids in the context of forensic and toxicological analysis.

[PMID: 29173162 DOI: 10.2174/1389201018666171122113934] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2017] [Revised: 08/18/2017] [Accepted: 11/10/2017] [Indexed: 11/22/2022]
Abstract
BACKGROUND Urine is a common biological sample to monitor recent drug exposure, and oral fluid is an alternative matrix of increasing interest in clinical and forensic toxicology. Limited data are available about oral fluid vs. urine drug disposition, especially for synthetic cannabinoids. OBJECTIVE To compare urine and oral fluid as biological matrices to monitor recent drug exposure among HIV-infected homeless individuals. METHODS Seventy matched urine and oral fluid samples were collected from 13 participants. Cannabis, amphetamines, benzodiazepines, cocaine and opiates were analyzed in urine by the enzyme-multipliedimmunoassay- technique and in oral fluid by liquid chromatography tandem mass spectrometry (LCMSMS). Eleven synthetic cannabinoids were analyzed in urine and in oral fluid by LC-MSMS. RESULTS Five oral fluid samples were positive for AB-FUBINACA. In urine, 4 samples tested positive for synthetic cannabinoids PB-22, 5-Fluoro-PB-22, AB-FUBINACA, and metabolites UR-144 5-pentanoic acid and UR-144 4-hydroxypentyl. In only one case, oral fluid and urine results matched, both specimens being AB-FUBINACA positive. For cannabis, 40 samples tested positive in urine and 30 in oral fluid (85.7% match). For cocaine, 37 urine and 52 oral fluid samples were positive (75.7% match). Twenty-four urine samples were positive for opiates, and 25 in oral fluid (81.4% match). For benzodiazepines, 23 samples were positive in urine and 25 in oral fluid (85.7% match). CONCLUSION/DISCUSSION These results offer new information about drugs disposition between urine and oral fluid. Oral fluid is a good alternative matrix to urine for monitoring cannabis, cocaine, opiates and benzodiazepines recent use; however, synthetic cannabinoids showed mixed results.

Abstract
Oral fluid has become an important matrix for drugs of abuse analysis. These days the applicability is challenged by the fact that an increasing number of new psychoactive drugs are coming on the market. Synthetic cannabinoids and synthetic cathinones have been the main drug classes, but the diversity is increasing and other drugs like piperazines, phenethylamines, tryptamines, designer opioids and designer benzodiazepines are becoming more prevalent. Many of the substances are very potent, and low doses ingested will lead to low concentrations in biological media, including oral fluid. This review will highlight the phenomenon of new psychoactive substances and review methods for oral fluid drug testing analysis using on-site tests, immunoassays and chromatographic methods.

Abstract
This review summarizes the literature to date relating to pyrolysis and heated vapour ingestion of drugs of abuse. In this context, heating is referred to as smoking or pyrolysis, but these are generic descriptors that encompass numerous methods of vapour generation and inhalation. Depending on the amount of drug used, diluents and contaminants present, heating conditions, and the oxidative/reductive environment, many thermal decomposition products can be formed. In addition to the recognized hazard of rapid onset of pharmacological effects of the parent drug, thermal decomposition products may be pharmacologically active as well as acutely/chronically toxic. For example, several published reports have linked heroin smoking to a form of brain encephalopathy and to the development of movement disorders. Early qualitative studies focusing on the thermal decomposition of drugs have evolved into more complex investigations employing mass spectral identification, confirmation, and elucidation of formation mechanism. In most cases, thermal decomposition begins with cleavage of the weakest bond (often C-N) to generate free radicals that then form the most stable sterically favoured products. Several reports of rearrangements at higher temperatures have been identified and hint at an underlying complexity that arises from the variety of smoking methods and conditions. Given that many designer drugs such as synthetic cannabinoids are ingested primarily through smoking, this issue has taken on new importance.

Abstract
Synthetic cannabinoids (SC), originally developed as research tools, are now highly abused novel psychoactive substances. We present a comprehensive systematic review covering in vivo and in vitro animal and human pharmacokinetics and analytical methods for identifying SC and their metabolites in biological matrices. Of two main phases of SC research, the first investigated therapeutic applications, and the second abuse-related issues. Administration studies showed high lipophilicity and distribution into brain and fat tissue. Metabolite profiling studies, mostly with human liver microsomes and human hepatocytes, structurally elucidated metabolites and identified suitable SC markers. In general, SC underwent hydroxylation at various molecular sites, defluorination of fluorinated analogs and phase II metabolites were almost exclusively glucuronides. Analytical methods are critical for documenting intake, with different strategies applied to adequately address the continuous emergence of new compounds. Immunoassays have different cross-reactivities for different SC classes, but cannot keep pace with changing analyte targets. Gas chromatography and liquid chromatography mass spectrometry assays - first for a few, then numerous analytes - are available but constrained by reference standard availability, and must be continuously updated and revalidated. In blood and oral fluid, parent compounds are frequently present, albeit in low concentrations; for urinary detection, metabolites must be identified and interpretation is complex due to shared metabolic pathways. A new approach is non-targeted HRMS screening that is more flexible and permits retrospective data analysis. We suggest that streamlined assessment of new SC's pharmacokinetics and advanced HRMS screening provide a promising strategy to maintain relevant assays.

Determination and identification of synthetic cannabinoids and their metabolites in different matrices by modern analytical techniques - a review. Anal Chim Acta 2015; 874:11-25. [PMID: 25910441 DOI: 10.1016/j.aca.2014.12.055] [Citation(s) in RCA: 58] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2014] [Revised: 12/16/2014] [Accepted: 12/31/2014] [Indexed: 10/24/2022]
Abstract
Synthetic cannabinoids have gained popularity due to their easy accessibility and psychoactive effects. Furthermore, they cannot be detected in urine by routine drug monitoring. The wide range of active ingredients in analyzed matrices hinders the development of a standard analytical method for their determination. Moreover, their possible side effects are not well known which increases the danger. This review is focused on the sample preparation and the determination of synthetic cannabinoids in different matrices (serum, urine, herbal blends, oral fluid, hair) published since 2004. The review includes separation and identification techniques, such as thin layer chromatography, gas and liquid chromatography and capillary electrophoresis, mostly coupled with mass spectrometry. The review also includes results by spectral methods like infrared spectroscopy, nuclear magnetic resonance or direct-injection mass spectrometry.
