The hallucinogenic psychedelic drug of the lysergamide family is 1p-lsd or 1-propionyl-lysergic acid diethylamide (abbreviated as 1P-LSD or 1P-LAD). It was advertised as a legal alternative to LSZ, AL-LAD and LSD during the first few months of 2015.
Since it is new, it has not been published in any formal scientific literature and is almost entirely unknown to both scholars and the public and has little or no history of human use.
The structural similarity reliably indicates an exceedingly close effect profile, given its similarity to LSD and ALD-52. Because of the lack of substance-related research, any discussion of its pharmacology is focused solely on its structure and subjective impact similarity to other lysergamides.
