These synthetic cannabinoids act directly at cannabinoid CB1 and CB2 receptors as does Δ9-tetrahydrocannabinol (Δ9-THC) found in marijuana, but have different chemical structures unrelated to Δ9-THC, different metabolism, and often greater toxicity (Fantegrossi et al., 2014). Discriminative stimulus effects were tested in rats trained to discriminate Δ9-tetrahydrocannabinol (3 mg/kg, 30-min pretreatment). 5F-MDMB-PINACA (also known as 5F-ADB, 5F-ADB-PINACA), MDMB-CHIMICA, MDMB-FUBINACA, ADB-FUBINACA, and AMB-FUBINACA (also known as FUB-AMB, MMB-FUBINACA) were tested for in vivo cannabinoid-like effects to assess their abuse liabilit
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 adb butinaca observed between 0–30 min. Duration of the locomotor depression increased over dose from 30 min following 0.1 mg/kg to 2.5 h following 1 mg/k
As synthetic cannabinoid receptor agonists (SCRA) are gaining popularity globally, clinicians have to understand that intoxication caused by vaping SCRA is not detected by commonly available tests. He confirmed that he had been vaping an electronic cigarette (e-cigarette) earlier that day just before the onset of his symptoms. Metabolic acidosis (1/3, 0/7) and respiratory acidosis (1/3, 0/7), All 10 patients recovered with supportive care, including intubation and ventilation for one case. In 3 cases ADB-BUTINACA was the only substance detected, while in seven other substances of misuse were also detected including other SCRA, opioids, benzodiazepines cocaine and pregabali

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 adb butinaca 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
Some mice showed abnormal behaviors (catalepsy, loss of traction, convulsion) right after the administration of the tested substances. The locomotor activity of the mice was measured 30 min and 2 hrs after the last substance administration. We also examined their neurotoxicity using brain samples through histopathological diagnose, especially in the nucleus accumbens core region. In histopathological analysis, neural cells of the animals treated with the high dose (5 mg/kg) of JWH-081 or JWH-210 showed distorted nuclei and nucleus membranes in the core shell of nucleus accumbens, suggesting neurotoxicity.

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.
