1-Acetyl-N,N-diethyllysergamide ( ALD-52, 1-Acetyl-LSD, 1A-LSD, 1A-LAD) is a lesser-known psychedelic substance of the lysergamide class.Also, produces LSD-like psychedelic effects when administered. It is structurally related to psychedelic lysergamides like LSD and 1P-LSD. Thus, it produces largely indistinguishable effects.

It is an analytical reference material categorized as a lysergamide.{35563} It has psychotomimetic properties that are equipotent to those of LSD.{47472} This product is intended for research and forensic applications.

ALD-52 was originally discovered by Albert Hofmann in his study of LSD analogs. However, it did not enter mainstream awareness until the 1960s Western youth counterculture. It likely acts as a 5-HT2A partial agonist. The psychedelic effects are believed to come from ALD52’s efficacy at the 5-HT2A receptors. It  is a semisynthetic molecule, meaning that its synthesis involves natural compounds  just like LSD

Alexander Shulgin touches briefly on the subject of ALD-52 in the commentary section of LSD-25 in the book TiHKAL. His writings  state that doses in the 50-175 µg range result in various effects similar to LSD. His reports indicate that it produces less visual distortion than with LSD. Also he stated less anxiety and tenseness and less potent than LSD. Another report found the two substances to be indistinguishable. As with LSD itself, ALD-52 does not meet the criteria to be considered addictive or toxic by the scientific community.[2][3] Nevertheless, unpredictable adverse reactions such as anxietyparanoiadelusions and psychosis are always possible, particularly among those who are predisposed to psychiatric disorders.[4] While these negative reactions or “bad trips” can often be attributed to factors like user inexperience or improper preparation of set and setting, they are known to happen spontaneously among even highly experienced users as well. It is highly advised to approach this very potent, long-lasting hallucinogenic substance with the proper amount of preparation, and harm reduction practices if using it.
