What is a common psychological effect reported in individuals using PCP?

Individuals using PCP (phencyclidine) often experience significant disruptions in cognitive functions, particularly in memory. Users may report difficulties in recalling events or information, which can be attributed to how PCP affects neurotransmitter systems in the brain. This substance alters sensory perceptions and can lead to dissociative effects, making it hard for users to form and retain new memories during its active phase.

While some people might experience high energy levels and altered states of consciousness, these effects are temporary and do not generally include focused or improved cognitive functions like concentration. Severe anxiety can indeed occur but tends to manifest more as a psychological response to the disorientation and paranoia that can accompany PCP use rather than being a direct cognitive impairment like memory problems. Thus, memory problems stand out as a particularly common and troubling effect among users of PCP.
