2-Oxo-LSD, also known as 2-oxy-LSD or 2-keto-LSD, or more fully as 2-oxo-2,3-dihydro-LSD, is a lysergamide and metabolite of the psychedelic drug lysergic acid diethylamide (LSD). It is a metabolite of LSD in both humans and various animal species, although there are important differences in LSD metabolism and relative proportions of metabolites between species.
