4F-MDMB-BINACA, also recognized as 4F-MDMB-BUTINACA or 4F-ADB, belongs to the indazole-3-carboxamide family and is classified as a synthetic cannabinoid. This compound has been utilized as an active component in synthetic cannabis products and has been available as a designer drug since late 2018. It acts as an agonist for the CB1 receptor, with an EC50 value of 7.39 nM, although its selectivity remains uncertain. Notably, in December 2019, the United Nations Office on Drugs and Crime (UNODC) introduced scheduling recommendations to categorize 4F-MDMB-BINACA as a Schedule II substance worldwide.
