Hallucinogens are a class of psychoactive drugs, either synthetic or plant-derived, that produce auditory or visual hallucinations and alter thought, mood, and perception. Depending on dosage, user expectation (set), and environment (setting), they can also induce euphoria or a state similar to a transcendental experience. Some hallucinogens, like jimsonweed, cause delirium with disturbances in judgment and memory, while others, such as LSD, psilocybin, DMT, and mescaline, alter consciousness without delirium or sedation. These serotonergic hallucinogens primarily affect the serotonin receptor system. Other plant products with hallucinogenic activity include morning glory seeds and Hawaiian baby woodrose seeds, which contain lysergic acid derivatives.
