A psychedelic lysergamide is a compound that has the chemical structure of a lysergamide and leads to psychedelic effects when taken. The most common example of a psychedelic lysergamide is LSD, which is lysergic acid diethylamide. Psychedelic lysergamides tend to have very quick onsets of action when compared to other psychedelic drugs because psychedelic lysergamides activate both serotonin and dopamine receptors instead of just serotonin receptors. The exact duration of the effect can vary depending on the type of lysergamide taken. Some of the most common effects of the compound include visual hallucinations, auditory changes, and alterations in sensory perception.
