Bizarre behavior is a common reaction associated with the use of PCP (phencyclidine), often due to its strong dissociative effects. PCP can alter perceptions of reality, leading to disconnect from one's environment and self, which may manifest as erratic or irrational behavior. Users may exhibit aggression, agitation, and impaired judgment, which are characteristic of this substance’s impact on the cognitive and emotional aspects of functioning.

In contrast, substances that enhance memory or increase inhibition are not effects typically associated with PCP. The compound can lead to a controversial dissociative state rather than enhancing cognitive functions. Additionally, PCP usage is more often linked to increased heart rate instead of decreased, making the implications of its effects markedly different from what might be expected from substances influencing inhibition or cognitive enhancement.
