psychedelics

Psychedelics are a class of psychoactive substances that profoundly alter perception, mood, and various cognitive processes. They often cause changes in sensory experiences, thought patterns, and a sense of time or self. Common examples include substances like LSD, psilocybin (from certain mushrooms), and mescaline. Psychedelics primarily act on serotonin receptors in the brain, particularly the 5-HT2A receptor, leading to their characteristic effects.
