Psychedelics are a class of psychoactive compounds that alter cognition, perception, and mood. Commonly known for their hallucinogenic effects, psychedelics evoke visual and auditory distortions, heightened senses, altered perception of time, and sense of oneness. Classic psychedelics work by primarily acting on serotonin 5-HT2A receptors and decreasing blood flow to certain brain regions like the default mode network, which involves higher-order introspection. Due to their unifying properties, psychedelics have been involved in many religious and spiritual experiences, with a more recent advancement in psychedelic therapy for relieving depression, anxiety, and substance withdrawal.
