Mechanism of Action: LSD acts as a partial agonist at serotonin 5-HT2A receptors, with additional activity at 5-HT1A, 5-HT2B, 5-HT2C, and dopamine D2 receptors.

Metabolism: Metabolized in the liver primarily by CYP3A4 and CYP2D6 enzymes. Major metabolites include 2-oxo-3-hydroxy-LSD and various hydroxylated derivatives.

Half-life: Approximately 3-5 hours, with effects typically lasting 8-12 hours.

Bioavailability: ~70% when taken orally, with peak plasma concentrations reached within 1-2 hours.
