[edit] Effects

It has the same characteristics as LSD, but supposedly "without the anxiety, tenseness, and other problems inherent to it".

[edit] Dangers

In The Hallucinogens by Hoffer and Osmond (1967), ALD-52 (D,L-Acetyllysergic acid diethylamide) is listed as having a lower (approximately ¹/₅) intravenous toxicity (in rabbits), a lower (approximately ¹/₈) pyretogenic effect, an equal psychological effect in man, and double the antiserotonin effect as compared with LSD.

[edit] History

One of the underground chemist's labs reportedly made ALD-52, and got busted. This resulted in the first drug analogue trial, where the chemists claimed they did nothing wrong producing ALD-52, because LSD was the illicit drug. However, as the prosecution claimed, there were problems with such rationale, firstly, ALD-52 undergoes hydrolysis readily to LSD, and secondly the synthesis of ALD-52 required LSD (this was based on the methods available in the scientific literature at the time).
