1D-LSD, also known as 1-(1,2-dimethylcyclobutane-1-carbonyl)-LSD or as SYN-L-229, is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). It is believed to be a prodrug of LSD and has replaced 1V-LSD in Germany after 1V-LSD became covered by the German NpSG law in 2022.
