Noun: A hallucinogenic drug is a type of psychoactive substance that significantly alters perception, mood, and cognitive processes, primarily by inducing hallucinations or profoundly altered sensory experiences. These effects are distinct from those of stimulants or depressants.
The term is used to classify and describe substances based on their primary psychological effect.

- Example: "Psilocybin mushrooms are considered a classic hallucinogenic drug."
- "Dissociative hallucinogenic drug": Refers to substances like ketamine or PCP that induce a sense of detachment from oneself and the environment.
- Example: "The anesthetic ketamine is also a dissociative hallucinogenic drug."

The core meaning is tied to the induction of hallucinations (perceiving things that are not present) and altered sensory experiences (such as synesthesia, where one might "hear" colors or "see" sounds). It does not refer to drugs whose primary effect is sedation, stimulation, or pain relief, even if they can sometimes cause perceptual distortions.
