What impact do hallucinogens have on perception?

Hallucinogens primarily distort perception, leading to changes in the way an individual experiences their surroundings. These substances can alter sensory perceptions, such as sight and sound, by causing vivid visual or auditory hallucinations and modifying the understanding of time and space. This means that when someone consumes hallucinogens, their brain processes sensory information differently, which can result in experiences that feel intensely real but are not grounded in reality.

Distortion of perception includes phenomena such as seeing colors that are more vibrant, experiencing sounds in a more profound way, or feeling a sense of unity with the environment. These changes can lead to significant shifts in mood and emotional responses, further enhancing the subjective experience. This explanation highlights how hallucinogens can completely alter a person's awareness and comprehension of their environment, which is why the understanding that they distort perception is crucial in discussions about their effects.
