5F-MDMB-PICA is a potent agonist of both the CB1 receptor and the CB2 receptor with EC50 values of 0.45 nM and 7.4 nM, respectively.[7]

In the United States, 5F-MDMB-PICA was temporarily emergency scheduled by the DEA in 2019.[8] In December 2019, the UNODC announced scheduling recommendations placing 5F-MDMB-PICA into Schedule II.[9] In the United States 5F-MDMB-PICA was made a permanent Schedule I Controlled Substance nationwide on April 7, 2022.[10]
