Psychedelics are a class of substances that alter perception, mood, and cognitive processes. Common examples include LSD, psilocybin (found in magic mushrooms), and DMT. These substances can lead to experiences often described as mystical or profound, affecting how individuals perceive reality and their sense of self. Research into psychedelics has gained attention for their potential therapeutic benefits, particularly in treating conditions like depression, anxiety, and PTSD. Studies suggest that, when used in controlled settings, psychedelics may help facilitate emotional breakthroughs and enhance psychological well-being, although more research is needed to fully understand their effects and safety.
