Synthetic cannabinoids have consistently been shown to produce discriminative stimulus effects similar to those adb butinaca of Δ9-THC (Bannister and Connor, 2018), and MDMB-FUBINACA fully substituted for Δ9-THC (Gamage et al., 2018). The chemical structures of the recent synthetic cannabinoids are unlike that of Δ9-THC, but are largely based on the structure of older synthetic cannabinoids that are known to have substantial abuse liability (Fig. 1). 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. Subsequent testing identified 5F-ADB to have been present in a total of ten people who had died from unexplained drug overdoses in Japan between September 2014 and December 2014.

Pretreatment times and dose ranges for the drug discrimination assay were selected based on the time of peak depression in the locomotor activity assay in mice. 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. All five of the compounds in the present study fully substituted with a pretreatment time of 15 min, suggesting a rapid onset of the discriminative stimulus effects. All of the cathinones fully substituted for the discriminative stimulus effects of Δ9-tetrahydrocannabinol (≥80% drug-appropriate responding).

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. 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 humans. Drug discrimination is a well-known animal model of the subjective effects of drugs and correlates well with abuse liability (Young 2009; Horton et al. 2013). Assessment of abuse liability is based on several factors, including chemical structure, pharmacological mechanism of action, and finally, subjective and reinforcing behavioral effects (FDA, 2010; Swedberg, 2013).
