What drug's usage is associated with significant and prolonged psychotic effects?

Phencyclidine, commonly known as PCP, is a dissociative drug known for its association with significant and prolonged psychotic effects. When ingested, PCP can induce symptoms such as hallucinations, delusions, and severe alterations in perception. These effects can persist long after the drug's immediate effects have worn off, leading to extended episodes of psychosis. This is particularly concerning for individuals who may have underlying mental health issues, as the drug can exacerbate these conditions.

In contrast, while cocaine and LSD can also lead to altered states of consciousness and potential psychological disturbances, their effects are generally more acute and less prolonged compared to PCP. Cocaine, a stimulant, typically promotes short-term euphoria and increased energy, which may not lead to prolonged psychotic effects. LSD, although capable of causing hallucinations, often results in a less persistent psychosis, with most effects residing shortly after use. Benzodiazepines, primarily used as anxiolytics, do not typically cause significant psychotic effects; instead, they tend to induce sedation and relaxation.

Understanding the distinct effects of these substances allows for better recognition and management of drug-induced psychosis, highlighting PCP’s unique and concerning profile in this regard.
