What is a common psychological effect of hallucinogenic drugs?

Hallucinogenic drugs are known for their profound impact on perception, mood, and cognition. One of the most significant psychological effects of these substances is altered sensory perception. Individuals under the influence of hallucinogens often report changes in how they perceive visual and auditory stimuli, leading to experiences such as seeing vivid colors, shapes, or patterns that are not present in reality, as well as hearing sounds in a distorted manner. This alteration in perception can significantly transform the user’s interaction with their environment and can lead to experiences that feel profoundly real, yet are entirely subjective.

This characteristic effect is a core component of how hallucinogenic drugs are understood in pharmacology, as they interact with neurotransmitter systems in the brain, particularly those involving serotonin. In contrast, improved sleep quality, increased physical strength, and heightened concentration are typically not associated with the effects of hallucinogenic substances.
