True or False: Phencyclidine (PCP) can be classified as a stimulant, hallucinogen, or depressant.

Phencyclidine (PCP) is a disassociative anesthetic with effects that are primarily classified as hallucinogenic. While it can produce a range of psychological effects that may mimic some characteristics of stimulants or depressants in specific situations, its primary classification is as a hallucinogen. The complexity of PCP's effects can lead to misclassification, but it is not accurate to categorize it broadly as a stimulant or depressant. This nuance is what makes the statement false, as PCP does not fit neatly into all three drug classifications.
