Which category does PCP belong to?

PCP, or phencyclidine, is classified primarily as a hallucinogen due to its effects on perception, mood, and cognitive function. When ingested, it can lead to significant alterations in awareness, sensory perception, and thought processes, akin to other substances in this category. While PCP does have properties that may exhibit stimulatory effects, particularly at lower doses, and it can produce depressant-like effects at higher doses, its most defining characteristic is its hallucinogenic properties. Thus, identifying it predominantly as a hallucinogen aligns with its categorization in the realm of psychoactive substances.
