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.

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.

Tremors were observed 30 minutes following 1 mg/kg AMB-FUBINACA in 3 of 8 mice (data not shown).

One recent study has looked at other mechanisms of action in some of the older synthetic cannabinoids and reported that some produced varying amounts of activity at sites which are related to cardiotoxicity and heart disease (Wiley et al., 2016). It is not known whether the increased toxicity is due only to activation of CB1 cannabinoid receptors more strongly than Δ9-THC or whether these "super-strength" cannabinoids produce effects at other receptors. A major cause of concern is that some of the more recently seen synthetic cannabinoids are more likely to produce extremely toxic effects than the older synthetics (Tai and Fantegrossi, 2017<br><br>Fig. 2. <br>Separation of compounds was performed on a 2.1 mm×100 mm, 1.7 [https://cannabinoidsrc4f-adb.com/ https://cannabinoidsrc4f-adb.com/] μm particle size ACQUITY Torus™ DIOL analytical column (Waters) with guard cartridge.
