It is illegal to sell, distribute, supply, transport or trade the pharmaceutical drug under the Psychoactive Substances Act 2016. The corresponding indole core analogue, 4F-MDMB-BICA (4F-MDMB-BUTICA), has also been widely sold as a designer drug by chemical providers on the internet, first being identified in May 2020. It has been used as an active ingredient in synthetic cannabis products and sold as a designer drug since late 2018. 4F-MDMB-BINACA (also known as MDMB-4F-BINACA using systematic EMCDDA nomenclature or 4F-MDMB-BUTINACA) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family.

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 4F ADB 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
Subsequently, a one-way analysis of variance was conducted on horizontal activity counts for the 30-min period of maximal effect, and planned comparisons were conducted for each dose against the vehicle control using single degree-of-freedom F test
These synthetic cannabinoids act 4F ADB 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
Such decrease remained 2 hr after the administration (Table 4). In locomotor activity, methamphetamine treated group showed approximately 4.2 times increase compared to the negative control treated group. Change of body weight following the treatments with JWH-081 and JWH-210 in mic
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
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

Separation of compounds was performed on a 2.1 mm×100 mm, 1.7 4F ADB μm particle size ACQUITY Torus™ DIOL analytical column (Waters) with guard cartridge. Measurements were performed by an ACQUITY UPC2 supercritical fluid chromatography system (Waters) coupled with a Xevo TQ-S Triple Quadrupole Mass Spectrometer (Waters). During the death scene examination, multiple cigarette butts without filters were found in an ashtray; also found were alcohol bottles, an unopened box of nebivolol-containing drug, and 18 g of unrecognizable herbal residue in a cigarette box.
Victim B also brought "something resembling a drug" (unrecognizable by Witness A) from his cousin (Witness B) in a cigarette box and mixed this substance with their tobacco. The half-maximal effective concentration (EC50) of 4F-MDMB-BINACA is 5.69 nM (2.76–11.0 nM) on CB1, and 0.69 nM (0.30–1.56 nM) on CB2, in vitro half-life (t1/2) is 10.27 min . It is usually available as a powder, liquid (vapor fluid), or herbal plant mixtur
The same procedure was then applied to the mice once every day for 5 days. It was considered as coordination disturbance when mice fell from the test apparatus within 2 min. Mice that remained their position on the running apparatus at 10 rpm for at least 2 min were selected for further evaluation.

After the incubation, mixture was centrifuged (18,000 x g, 20 °C) for 5 min and 0.5 μL of the supernatant was directly injected to the chromatographic system. In the next step, ammonium formate as salting agent was added to the mixture and incubated in a thermomixer (20 °C, 1200 rpm) for 15 min. After vortex-mixing, the mixture was allowed to stand 4F ADB at room temperature for 5 min. MS/MS experiments were performed in MRM (multiple reaction monitoring) mode with an isolation window of 0.4 m/z. The MS measurement was performed in positive ion mode (except for some acidic compounds such as barbiturates
