1P-ETH-LAD (1-propionyl-6-ethyl-6-nor-lysergic acid diethylamide) is an analog of LSD. 1P-ETH-LAD is a psychedelic drug similar to LSD. Research has shown formation of ETH-LAD from 1P-ETH-LAD incubated in human serum, suggesting that it functions as a prodrug. It is part of the lysergamide chemical class. Like ETH-LAD, this drug has been reported to be significantly more potent than LSD itself, and is reported to largely mimic ETH-LAD's psychedelic effects.
1P-ETH-LAD has little history of human usage before January 2016.
