4F-MDMB-BINACA

4F-MDMB-BINACA (also known as 4F-MDMB-BUTINACA or 4F-ADB) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family.[1] It has been used as an active ingredient in synthetic cannabis products and sold as a designer drug since late 2018.[2][3] 4F-MDMB-BINACA is an agonist of the CB1 receptor (EC50 = 7.39 nM),[4] though it is unclear whether it is selective for this target.[5] In December 2019, the UNODC announced scheduling recommendations placing 4F-MDMB-BINACA into Schedule II throughout the world.[6]

The corresponding indole core analogue, 4F-MDMB-BICA or 4F-MDMB-BUTICA has also been widely sold as a designer drug by chemical providers on the net, first being identified in May 2020.[7]

United Kingdom

It's illegal to sell, distribute, supply, transport or trade the pharmaceutical drug under the Psychoactive Substances Act 2016.

In the United States, the DEA has filed a notice for its intent to temporarily place 4F-MDMB-BUTICA (but not 4F-MDMB-BINACA itself) into Schedule I status starting on or after May 4, 2023, for up to 2 years, during which it's possible the DEA could file for permanent scheduling within those 2 years. If it is filed on May 4, 2023, and the DEA does not file to permanent placement the temporary Schedule I order will expire on May 4, 2025.[8]
