4F-MDMB-BINACA (also known as MDMB-4F-BINACA, 4F-MDMB-BUTINACA or 4F-ADB) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family. 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. 4F-MDMB-BINACA is an agonist of the CB1 receptor (EC₅₀ = 7.39 nM), though it is unclear whether it is selective for this target. In December 2019, the UNODC announced scheduling recommendations placing 4F-MDMB-BINACA into Schedule II throughout the world.

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.

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.

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.

North Dakota has placed 4F-MDMB-BINACA into Schedule I on 04/27/2023.
