N,N-Diallyllysergamide (DAL), also known as lysergic acid diallylamide (LDA), is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD).12 It is taken orally.1

Use and effects

In his 1997 book TiHKAL (Tryptamines I Have Known and Loved), Alexander Shulgin described DAL as producing "at best a touch of sparkle" of LSD at dose of 600 μg of the tartrate salt taken orally, but as also producing a sedation.1 Subsequently, in a 2003 literature review, Shulgin listed an active dose as greater than 1 mg.3 He has described the drug as being at least an order of magnitude less potent than LSD.13

Interactions

Pharmacology

Pharmacodynamics

DAL interacts with serotonin receptors, including the serotonin 5-HT1A, 5-HT2A, and 5-HT2C receptors.2 It acts as a serotonin 5-HT2A receptor agonist, but with about 5-fold lower potency than LSD.2

As the tartrate salt, there is at best a touch of sparkle seen at 600 micrograms orally, but there is a sedation also reported. It is certainly an order of magnitude less potent than LSD itself."
