4F-MDMB-BINACA

Summary

4F-MDMB-BINACA, also recognized as 4F-MDMB-BUTINACA or 4F-ADB, belongs to the indazole-3-carboxamide family, making it an indazole-based synthetic cannabinoid. It has been prevalent as an active component in synthetic cannabis products and has been accessible as a designer drug since late 2018. 4F-MDMB-BINACA acts as an agonist of the CB1 receptor (with an EC50 of 7.39 nM), but its selectivity for this specific target remains uncertain. Notably, in December 2019, the United Nations Office on Drugs and Crime (UNODC) introduced scheduling recommendations, proposing the classification of 4F-MDMB-BINACA as a Schedule II substance on a global scale.

Under the Psychoactive Substances Act 2016, it is illegal to engage in the sale, distribution, supply, transportation, or trade of this pharmaceutical drug.
United States:
The DEA has issued a notice of intent to temporarily designate 4F-MDMB-BUTICA (not including 4F-MDMB-BINACA itself) as a Schedule I substance. This designation is set to commence on or after May 4, 2023, with a potential duration of up to 2 years. During this period, the DEA may pursue permanent scheduling. Should no such filing occur by May 4, 2025, the temporary Schedule I classification will lapse.
