hallucinogenic drug
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. It is a formal and clinical term common in medical, scientific, and legal contexts. - It functions as a countable noun (e.g., a hallucinogenic drug, several hallucinogenic drugs). - It is often shortened informally to "hallucinogen."

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.
