Synthetic cannabinoids have consistently been shown to produce discriminative stimulus effects similar to those of Δ9-THC (Bannister and Connor, 2018), and MDMB-FUBINACA fully substituted for Δ9-THC (Gamage et al., 2018).
All 5 compounds decreased locomotor activity and produced discriminative stimulus effects similar to those of Δ9-THC, which suggests they may have abuse liability similar to that of Δ9-THC.
Substantial depressant effects were observed within the first 10 min, and maximal depression was observed between 0–30 min following administration.
The LC-QTOF-MS analysis showed that the e-liquid contained nicotine and ADB-BUTINACA (Fig. 1).
When clinical presentation and/or initial recreational drugs testing results are inconclusive, additional testing with LC-QTOF-MS can be valuable.
The mixture was vortexed mixed and incubated in triplicate at 37 °C in a shaking water bath (100 rpm) for 1 h.
Acute kidney damage and even kidney failure have been reported following use of synthetic cannabinoids (Davidson, et al., 2017).
A point-of-care drugs of abuse (DOA) test was initially performed on the urine of the patient.
We also demonstrated that JWH-210 administration resulted in the decrease of expression levels of T-cell activator including Cd3e, Cd3g, Cd74p31, and Cd74p41, while JWH-030 increased Cd3g levels.
Locomotor activity in mice was tested to screen for locomotor depressant effects and to identify behaviorally-active dose ranges and times of peak effect.
Substantial depressant effects were observed within the first 10 min, and maximal depression was observed between 0–30 min following administration.
Percent drug-appropriate responding was shown only if at least three rats completed the first fixed ratio, whereas all rats are shown for the response rate data.
Oxidation of 4′-hydroxybutyl moiety in B2 led to formation of 4′-carboxybutyl metabolite (B4) having a precursor ion of m/z 362, which was 14 Da higher than the m/z for B2 (loss of two hydrogen atoms with addition of a carbonyl group).
Tremors were observed 30 minutes following 1 mg/kg AMB-FUBINACA in 3 of 8 mice (data not shown).
Twenty-four male Sprague-Dawley rats were obtained from Envigo (Houston, TX).
Separation of compounds was performed on a 2.1 mm×100 mm, 1.7 μm particle size ACQUITY Torus™ DIOL analytical column (Waters) with guard cartridge.
Tremors were observed 30 minutes following 1 mg/kg AMB-FUBINACA in 3 of 8 mice (data not shown).
It is important to note that JWH-210 Chemical Powder is intended strictly for research and laboratory use only.
Furthermore, users of these vapes and alerting authorities may not notice the addition of recreational drugs to the e-liquid as the smell of recreational drugs is lost during vaping due to the specific smell of added flavours .
The intensity is plotted against the retention time for both chromatograms, demonstrating the presence and elution profiles of nicotine and ADB-BUTINACA in the analysed vape liquid sample.
This might be due to the low activity of numerous metabolizing enzymes resulting in lower drug biotransformation .
This is the first case report that describes the toxicological symptoms of vaping ADB-BUTINACA.
All of the synthetic cannabinoids tested in the present study fully substituted for the discriminative stimulus effects of Δ9-THC.
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.
Second, we could not retrieve further detailed information about the e-cigarette that was used by the patient such as the label or the region of origin.
