4F-MDMB-BINACA (also known as MDMB-4F-BINACA,[2]4F-MDMB-BUTINACA or 4F-ADB) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family.[3] It should not be confused with the amantadine analogue 4F-ABINACA. It has been used as an active ingredient in synthetic cannabis products and sold as a designer drug since late 2018.[4][5] 4F-MDMB-BINACA is an agonist of the CB1 receptor (EC50 = 7.39 nM),[6] though it is unclear whether it is selective for this target.[7] In December 2019, the UNODC announced scheduling recommendations placing 4F-MDMB-BINACA into Schedule II throughout the world.[8]
Related compounds
The corresponding indole core analogue, 4F-MDMB-BICA (4F-MDMB-BUTICA), has also been widely sold as a designer drug by chemical providers on the internet, first being identified in May 2020.[9]
Legal Status
United Kingdom
It is illegal to sell, distribute, supply, transport or trade the pharmaceutical drug under the Psychoactive Substances Act 2016.
United States
4F-MDMB-BINACA is considered a Schedule I controlled substance as a positional isomer of the Schedule I compound 5F-AMB (5F-MMB-PINACA / 5F-AMB-PINACA). There has been charges brought against individuals for possession and distribution of 4F-MDMB-BINACA due to it being a positional isomer of 5F-AMB.[10]
The DEA has temporarily placed 4F-MDMB-BUTICA (the indole core analog of 4F-MDMB-BINACA) into Schedule I status starting on December 12th, 2023, for up to 2 years, during which it's possible the DEA could file for permanent scheduling within those 2 years. If the DEA does not file to permanent placement the temporary Schedule I order will expire on December 12th, 2025.[11]
North Dakota has placed 4F-MDMB-BINACA into Schedule I on 04/27/2023.[12]
