How do hallucinogens like PCP affect perception?

Hallucinogens such as PCP (phencyclidine) are known for their profound effects on an individual's perception, particularly concerning sensory experiences. This class of drugs can significantly alter visual and auditory senses, leading to distortions in the perception of reality. For example, PCP may cause users to see colors more vividly, perceive objects as distorted or moving, or hear sounds that are not present. These alterations can lead to a breakdown of the boundaries between self and environment, causing a disorienting experience.

Understanding this effect is crucial, as the altered perception induced by hallucinogens can impact a person's response to situations, influencing their behavior and interactions within the surrounding environment. The emphasis on sensory alteration distinguishes this option from others, as hallucinogens are not generally known for enhancing physical strength, increasing hunger, or directly inducing aggression in the way some other substances might. Instead, the primary effects of hallucinogens revolve around changes in perception, making this an important consideration in understanding their impact on individuals.
