In general, the locomotor depressant and discriminative stimulus effects adb butinaca have been observed at doses that do not produce adverse effects, although tremors were observed upon handling in mice that received JWH-210 (Gatch et al., 2016), and 5F-AMB produced sustained vocalization and convulsions in rats (Gatch et al., 2018). All of the synthetic cannabinoids tested in the present study fully substituted for the discriminative stimulus effects of Δ9-THC. 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 tests.

As mentioned previously, short-onset compounds have a greater abuse liability; further, compounds that have fewer adverse effects while they are active are likely to be preferred.

A limitation of this case report is that we did not have a urine sample available for additional NPS testing. Point-of-care DOA tests using urine to screen for misuse of multiple substances, regularly include cannabis, amphetamines, cocaine, opioids, benzodiazepines and methadone. THC, methamphetamine, SRCA, lysergic acid diethylamide (LSD), gamma-hydroxybutyrate (GHB) and ketamine are likely to become volatile under the temperature of current e-cigarettes, while crack cocaine is hard to vaporise. A systematic review including data of 114 patients of which the majority was intoxicated due to SCRA smoking revealed that 45 % of the patients who present at the ER after an intoxication due to SCRA smoking recovered within 24 hours


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.

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


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 4F ADB 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.
