ETH-LAD, 6-ethyl-6-nor-lysergic acid diethylamide is an analogue of LSD. It is described by Alexander Shulgin in the book TiHKAL. ETH-LAD is a hallucinogenic drug similar to LSD, and is slightly more potent than LSD itself with an active dose reported at between 40 and 150 micrograms. ETH-LAD has subtly different effects to LSD, described as less demanding.
ETH-LAD has been sold by some research chemical suppliers but might be considered illegal in some countries due to its structural similarity to LSD.
