Effects

6-Fluoro-DMT has been said to not be active as a hallucinogen in humans.^[3] It has been claimed that this is due to it being "metabolically blocked", though this was not further elaborated on.^[3] In the 1960s, it had been theorized by Stephen Szára and colleagues that psychedelic tryptamines were prodrugs that required 6-hydroxylation to become hallucinogenic, but this theory was later found to be incorrect.^[4][5][6][7] 6-Fluoro-DMT has been thought to be inactive as a psychedelic in part because 6-fluoro-DET is inactive in terms of such effects.^{[8][9][10][11][12]}

6-Fluoro-DMT is known to possess varying affinities for serotonin receptors, adrenergic receptors, dopamine receptors, histamine receptors, the imidazoline I₁ receptor, sigma receptors, and the serotonin transporter (SERT).^[2] It has been found to be a potent partial agonist of the serotonin 5-HT_2A receptor and a potent full agonist of the serotonin 5-HT_2C receptor.^[2] In another study however, it showed affinity for the serotonin 5-HT_1A and 5-HT_2A receptors but was inactive as a serotonin 5-HT_1A receptor agonist and showed low potency as a serotonin 5-HT_2A receptor agonist.^[14][15] On the other hand, it was only about 3-fold less potent than dimethyltryptamine (DMT) as a serotonin 5-HT_2A receptor agonist in this study.^[15] 6-Fluoro-DMT is less active than dimethyltryptamine (DMT) in producing effects in animal studies.^[1][16]

History

6-Fluoro was first described in the scientific literature by at least 1966.^[1][16][3]
