THPC (drug)
THPC, also known as 1-methyl-1,2,5,6-tetrahydropyridine-3-diethylcarboxamide, is a greatly simplified analogue of the psychedelic lysergamide lysergic acid diethylamide (LSD) in which only a modified version of the D ring (and its substitutions) remains. THPC was assessed and produced no behavioral effects by itself in rodents.
