25TFM-NBOMe (also known as NBOMe-2C-TFM, 2C-TFM-NBOMe, and Cimbi-138) is a derivative of the phenethylamine hallucinogen 2C-TFM, discovered by Ralf Heim at the Free University of Berlin by 2000.[1][2] It can be taken to produce psychedelic effects similar to 25I-NBOMe and 25D-NBOMe.[citation needed]

25TFM-NBOMe acts as a potent partial agonist for the serotonin 5-HT2A receptor, though its relative potency is disputed, with some studies finding it to be of lower potency than 25I-NBOMe,[7][8] while others show it to be of similar or higher potency,[9] possibly because of differences in the assay used.[10]

Chemistry

Analogues

Analogues of 25TFM-NBOMe include 2C-TFM, DOTFM, and TFMFly (DOTFM-FLY), among others.

History

25TFM-NBOMe was first described in the scientific literature by Ralf Heim and colleagues at the Free University of Berlin by 2000.[1][2]

Society and culture

Canada

25TFM-NBOMe is a controlled substance in Canada under phenethylamine blanket-ban language.[11]

United Kingdom

This substance is a Class A drug in the United Kingdom as a result of the N-benzylphenethylamine catch-all clause in the Misuse of Drugs Act 1971.[12]
