1-Acetyl-N,N-diethyllysergamide (also known as ALD-52, 1-Acetyl-LSD, 1A-LSD, 1A-LAD, and mistakenly as Orange Sunshine) is a lesser-known psychedelic substance of the lysergamide class that produces LSD-like psychedelic effects when administered. It's structurally related to psychedelic lysergamides like LSD and 1P-LSD and is reported to produce largely indistinguishable effects. ALD-52 was originally discovered by Albert Hofmann in his study of LSD analogs, but it did not enter mainstream awareness until the 1960s through Western youth counterculture.
Perspectives
“As expected this is somewhat similar to LSD with respect to the headspace. It diverges in terms of having a heavier bodyload, less visuals, and a sort of darker more neutral headspace, lacking the giddiness that LSD can sometimes impart.”
