LC-QTOF-MS represents a significant advancement in the field of drug detection, offering higher sensitivity, specificity, and a broader spectrum of detectable substances. Despite all negative results in the point-of-care test for recreational drugs, the liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) analysis showed that the liquid of the e-cigarette contained ADB-BUTINACA, a synthetic cannabinoid. We report a 27-year-old man who was admitted to the emergency room because of sudden adb butinaca headache, nausea, vertigo, red eyes and palpitations. Synthetic cannabinoids are gaining popularity globally and detection is not commonly available.

When clinical presentation and/or initial DOA testing results are inconclusive, additional testing with LC-QTOF-MS can be valuable and is recommended. SCRAs and other NPS may not be detected by point-of-care DOA tests. In this case, the point-of-care DOA urine screening was not able to detect the synthetic cannabinoid ADB-BUTINAC
Because response suppression may compromise stimulus control, rats failing to complete at least ten responses during the test session were excluded from the analysis of the discriminative stimulus effects of that dose of test compoun
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 lever. A houselight was centered over the hopper close to the ceiling and was illuminated only when the levers were active. Each dose range included doses that were without effect to those producing at least 50% depression compared to vehicle control. Twenty-four male Sprague-Dawley rats were obtained from Envigo (Houston, TX). adb butinaca Male ND4 Swiss–Webster mice were obtained from Envigo (Houston, TX) at approximately 8 weeks of age and maintained in the University of North Texas Health Science Center (UNTHSC) animal facility for two weeks prior to testin
AMB-FUBINACA has been implicated in severe adverse effects in recreational users (Adams et al., 2017; Hamilton et al., 2017), which suggests that the range between behaviorally active and toxic doses of AMB-FUBINACA is narro

The purpose of the present study was to assess the abuse liability of 5F-MDMB-PINACA, MDMB-CHIMICA, MDMB-FUBINACA, ADB-FUBINACA, and AMB-FUBINACA. The findings produce an apparent paradox, since CPP and self-administration predict with high reliability the likelihood that a compound will be abused by humans, and cannabinoids are well-known to produce active drug-seeking in humans. Drug discrimination is a well-known animal model of the subjective effects of drugs and correlates well with abuse liability (Young 2009; Horton et al. 2013). Assessment of abuse liability is based on several factors, including chemical structure, pharmacological mechanism of action, and finally, subjective and reinforcing behavioral effects (FDA, 2010; Swedberg, 2013).

Tremors were observed in mice 30 minutes following 1 mg/kg AMB-FUBINACA in the present study. Pretreatment times and dose ranges for the drug discrimination assay were selected based on the time of peak depression in the locomotor activity assay in mice. Average potency of the discriminative stimulus effects of early compounds was 0.81±0.17 mg/kg (Gatch et al., 2014), whereas the potency of a recent set was 0.09±0.03 mg/kg (Gatch et al., 2018), and the potency of the current set is 0.05±0.01 mg/kg. Short-onset, short-acting compounds have a greater abuse liability, and long-acting compounds pose problems of long-acting adverse effects and interactions with other drugs. The duration of action of the synthetic cannabinoids tested using the 8-h protocol have varied widely, with some producing a duration of action no longer than 1 h, others producing a duration of action between 1–2 h, and others lasting more than 2 h. There seems to be a trend of newer synthetic cannabinoids being more potent than earlier compound
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
