5F-ADB-PINACA is a cannabinoid designer drug that is an ingredient in some synthetic cannabis products. It is a potent agonist of the CB1 receptor and CB2 receptor with EC50 values of 0.24 nM and 2.1 nM respectively.[1][2]


Twelve 5F-ADB-PINACA major metabolites were identified in several incubations with cryopreserved human hepatocytes. Major metabolic reactions included oxidative defluorination followed by carboxylation.[3]


5F-ADB-PINACA is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015.[4]
