6-Ethyl-6-nor-lysergic acid diethylamide (also known as N-Ethyl-nor-lysergic acid N,N-diethylamide, N-Ethyl-nor-LSD and ETH-LAD) is a lesser-known novel psychedelic of the lysergamide class. ETH-LAD is chemically similar to LSD and has a similar mechanism of action. Thus, acting primarily by stimulating serotonin receptors in the brain.
The human use of ETH-LAD was first documented by Alexander Shulgin. This was in his 1997 book TiHKAL (“Tryptamines I Have Known and Loved”). Hence, it is noted for its “modified visual distortion” relative to LSD. It has been marketed alongside psychedelic lysergamides like 1P-LSD and AL-LAD as a legal, grey-market alternative
