ADB-PINACA

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 0.52 nM and 0.88 nM respectively.[1][2] Like MDMB-FUBINACA, this compound contains an amino acid residue of tert-leucine.

Side effects

ADB-PINACA has been linked to multiple hospitalizations and deaths due to its use.[3][4][5]

Metabolism

Nineteen ADB-PINACA major metabolites were identified in several incubations with cryopreserved human hepatocytes. Major metabolic reactions included pentyl hydroxylation, hydroxylation followed by oxidation (ketone formation), and glucuronidation.[6]

Legality

ADB-PINACA is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015.[7]

In the United States, it is a Schedule I controlled substance.[8]

As of October 2015 ADB-PINACA is a controlled substance in China.[9]
