1-Propionyl-d-lysergic acid diethylamide (also known as 1P-LSD) is a novel semi-synthetic psychedelic substance of the lysergamide class. 1P-LSD is closely related to LSD and is reported to produce near-identical effects. Little is known about the pharmacology of 1P-LSD, but it likely produces its psychedelic effects by acting on serotonin receptors in the brain.

Subjective effects of 1P-LSD are extremely similar to those of LSD. 1P-LSD is theorized to act as a prodrug for LSD. The similarities in chemical structure between 1P-LSD and LSD predicts a near-identical effect profile, likely differing mainly in its rate of absorption and duration. Characteristics effects include geometric visual hallucinations, time distortion, enhanced introspection, and ego loss. Its classical psychedelic effects and favorable tolerability has led it to become popular among novel psychoactive substance users who use it interchangeably with LSD.
