F-2 (drug)
F-2, also known as 6--5-methoxy-2-methyl-2,3-dihydrobenzofuran or as benzofuran-2-methyl-5-methoxy-6-, is a lesser-known psychedelic drug. F-2 was first synthesized by Alexander Shulgin. In his book PiHKAL, the minimum dosage is listed as 15 mg, and its duration is unknown. F-2 produces few to no effects at this dose in humans. Animal studies showed it to substitute for the psychedelic drug DOM, but with less than one tenth the potency. F-2 is the derivative of 6-APDB with a methyl group at the carbon atom of the 3,4-methylenedioxy ring and a methoxy group at the 6 position.
