MDMB-2201 MMB-2201 (also known as 5F-MMB-PICA, 5F-AMB-PICA, and I-AMB) is a potent indole-3-carboxamide based syntheticcannabinoid,which has been sold as a designer drug and as an active ingredient in synthetic cannabis blends.It was first reported in Russia and Belarus in January 2014, but has since been sold in a number of other countries. It is the indole core analogue of 5F-AMB. Synthetic cannabinoid compounds with an indole-3-carboxamide or indazole-3-carboxamide core bearing a N-1-methoxycarbonyl group with attached isopropyl or t-butyl substituent, have proved to be much more dangerous than older synthetic cannabinoid compounds previously reported, and have been linked to a large number of deaths in Russia, Japan, Europe and the United States.
