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 compounds. All of the compounds tested in the present study depressed locomotor activity as is typical for other synthetic cannabinoids (see review by Wiley et al., 2017). Average horizontal activity counts/10 min as a function of time (10 min bins) and dose. Depressant effects of 1.33 mg/kg were observed within 10 min following administration and peak depressant effects were observed between 0–30 min.

A 30-min period, beginning when maximal depression of locomotor activity first appeared as a function of dose, was used for analysis of dose-response data and calculation of ED50 values. During test sessions, both levers were active, such that ten consecutive responses on either lever led to 5CL ADBA powder reinforcement. The substitution tests occurred only if the rats had achieved 85% injection-appropriate responding on the two prior training sessions.
The locomotor activity assay was used to identify approximate time courses and dose ranges of psychoactive effects, which is useful for identifying parameters for drug discrimination experiments and are also predictive of the time course of the psychoactive effects in human users. 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. Since there is currently no robust measure of the reinforcing/rewarding effects of cannabinoids, drug discrimination is currently the best model for assessing abuse liability of cannabinoids. 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 human

Legal status
Briefly, the FOB test was comprised of several behavioral changes including catalepsy, traction, tremor, convulsion, exopthalmos, piloerection, salivation, lacrimation, diarrhea, skin coloration, pinna reflex, righting reflex, and death. The FOB test was performed using published procedures (Moser et al., 1989) with some modifications. However, because of their subjective properties, it is necessary to set up a more objective automated measurement to determine their neurotoxicity. However, there are only a couple of anecdotal reports suspecting the possibility of their neurotoxicity with no scientific evidence (Cohen et al., 2012; McGuinness and Newell, 2012; Harris and Brown, 2013; Hermanns et al., 2013
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 .

The intensity is plotted against the retention time for both chromatograms, demonstrating the 5CL ADBA powder 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
