25B-NBF (2C-B-NBF, NBF-2C-B) is a derivative of the phenethylamine hallucinogen 2C-B, which acts as a highly potent partial agonist for the human 5-HT_2A receptor.^[1]^[2]

Legality[edit]

Sweden[edit]

The Riksdag added 25B-NBF to Narcotic Drugs Punishments Act under swedish schedule I ("substances, plant materials and fungi which normally do not have medical use") as of January 26, 2016, published by Medical Products Agency (MPA) in regulation HSLF-FS 2015:35 listed as 25B-NBF, and 2-(4-bromo-2,5-dimetoxifenyl)-N-(2-fluorobensyl)etanamin.^[3]

United Kingdom[edit]

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.^[4]
