&lt;div&gt;High resolution mass spectrometry such as LC-QTOF-MS allows the detection and identification of a broad spectrum of recreational drugs, including new psychoactive substances. A point-of-care drugs of abuse (DOA) test was initially performed on the urine of the patient. He confirmed drinking 750 ml energy drink without any further consumption of food and using an e-cigarette from Gaziantep, Turkey 10 seconds before the onset of his first symptoms. He usually smokes a pack of cigarettes a day and sometimes smokes e-cigarettes. Combined with non-specific, transient symptoms, clinical recognition of SCRA intoxication is challenging .&amp;lt;br&amp;gt;Data availability &amp;lt;br&amp;gt;The intensity is plotted against the retention time for both chromatograms, demonstrating the [https://cannabinoidsrc4f-adb.com/ 5CLADBA] presence and elution profiles of nicotine and ADB-BUTINACA in the analysed vape liquid sample. LC-QTOF-MS Chromatograms of Nicotine (Top) and ADB-BUTINACA (Bottom) in the Vape Liquid used by the patient. The LC-QTOF-MS analysis showed that the e-liquid contained nicotine and ADB-BUTINACA (Fig. 1). Because the point-of-care DOA test is generally not able to detect synthetic recreational drug substances, the liquid of the e-cigarette was thereafter screened using liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) on the Waters™ Xevo G3 QTOF MS system. After eating a light meal and drinking caffeinated sports drinks at the ER, the nausea complaints of the patient were reduced and the patient was discharged hom&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;In the present study, we performed various methods based on animal behavioral testing including FOB test for general behavioral observation, rotarod test, locomotor activity test for motor function evaluation, and water-maze test for learning/memory evaluation. Known for its stability and consistent composition, this compound is frequently utilized by professionals seeking reliable materials for laboratory-based analytical studies. In this study, histopathological evaluation was performed to confirm the possibility of neurotoxicity of the tested substances by hematoxylin and eosin staining method from collected brain samples. In the present study, we evaluated the neurotoxicity of two synthetic cannabinoids (JWH-081 and JWH-210) through observation of various behavioral changes and analysis of histopathological changes using experimental mice with various doses (0.1, 1, 5 mg/kg). Selecting powder JWH-210 demands careful evaluation of purity, legality, and supplier credibility. Prices for research-grade JWH-210 vary significantly based on quantity, purity, and vendor complianc&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;The chemical structures of the recent synthetic cannabinoids are unlike that of Δ9-THC, but are largely based on the structure of older synthetic cannabinoids that are known to have substantial abuse liability (Fig. 1&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Thirty minutes prior to the training sessions, rats received an injection of either vehicle or Δ9-THC and were subsequently placed in the behavior-testing chambers, where food (45-mg food pellets; Bio-Serve, Frenchtown, NJ) was available as a reinforcer for every ten responses (FR10) on a designated injection appropriate leve&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Product ions detected at m/z 302, 217, and 145 (B2) confirmed that tert-leucine and indazole moieties remained unchanged, leading to the structure elucidation of a hydroxy-functional group at the 4-position of the butyl side chain by oxidative defluorination. The product ion m/z 336 (loss of methyl ester moiety) further confirmed the presence of dihydroxylated metabolites. The precursor ion, m/z 364 (B14, B5/B6) had a loss of 2 Da from m/z 366 indicated further dehydrogenation of the ester hydrolysis plus monohydroxylated metabolites. The presence of the product ion m/z 320, likely formed from a loss of carbon dioxide, indicated monohydroxylation at the tert-leucine in B8 (m/z 219), butyl side chain in B9 (m/z 145) and indazole moiety in B13 (m/z 161). The precursor ion, m/z 350 showed a loss of 14 Da explaining the hydrolysis of methyl ester from 4F-MDMB-BINACA.&amp;lt;br&amp;gt;Fig. 2. &amp;lt;br&amp;gt;The precursor ion m/z 396 (B10, B12/B15) was 32 Da higher than the parent drug, 4F-MDMB-BINACA, suggesting the addition of two hydroxy groups. All the below explanations for transformations into metabolites are based on the data shown in Fig. Metabolites were identified according to their precursor ions, product ions, and fragmentation patterns (Fig. 1). Traditional in-vivo metabolism studies to generate human metabolites of drugs relied heavily on the use of whole animal model systems, which are expensive, limited by drug administration amount, influenced by species variation and faced by many ethical issues. Eight in-vivo metabolites tentatively identified were mainly products of ester hydrolysis with or without additional dehydrogenation, N-dealkylation, monohydroxylation and oxidative defluorination with further oxidation to butanoic acid.&amp;lt;br&amp;gt;Fig. 1. &amp;lt;br&amp;gt;This outcome was anticipated since CES-mediated hydrolysis is commonly 5CLADBA reported as the major metabolic pathway among the SCBs impacting the terminal ester group . Glucosides and sulfate metabolites have been reported with other SCBs where C. From these three samples, sample 2 contained only an ester hydrolysis metabolite (m/z 350). Both ester hydrolysis followed by oxidative defluorination to butanoic acid (B4, m/z 362) and monohydroxylation at tert-leucine moiety (B8, m/z 366) metabolites were found in 16/20 urine samples (Table 2). A In-vitro metabolites observed in common among respective seven most abundant metabolites in b C. The product ion detected at m/z 235, indicating loss of sulfate, confirmed the identity of the sulfation metabolite.&amp;lt;br&amp;gt;Fungus C. elegans &amp;lt;br&amp;gt;Methyl (2S)-2-([1-(4-fluorobutyl)-1H-indazole-3-carbonyl]amino)-3,3-dimethylbutanoate (4F-MDMB-BINACA, 4F-MDMB-BUTINACA or 4F-ADB), found in numerous SCB product seizures, has been reported by various law enforcement since 2018 . However, most of the SCBs are full agonists at CB1 and CB2 receptors, having a higher risk of undesirable side effects when compared to THC which is a partial agonist . Synthetic cannabinoids (SCBs) are agonists at cannabinoid receptor type 1 (CB1) and type 2 (CB2), where they elicit their main effect&lt;/div&gt;</summary>
