AB-PINACA is a compound that was first identified as a component of synthetic cannabis products in Japan in 2012.[2]

It was originally developed by Pfizer in 2009 as an analgesic medication.[3][4]

AB-PINACA acts as a potent agonist for the CB1 receptor (Ki = 2.87 nM, EC50 = 1.2 nM) and CB2 receptor (Ki = 0.88 nM, EC50 = 2.5 nM) and fully substitutes for Δ9-THC in rat discrimination studies, while being 1.5x more potent.[5][6]

There have been a number of reported cases of deaths and hospitalizations in relation to this synthetic cannabinoid.[7][8]
