Psychedelic drugs are substances that alter perception, mood, and cognitive processes. Common examples include LSD, psilocybin (found in magic mushrooms), and DMT. These drugs can lead to experiences often described as mind-expanding or transformative, 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, these substances may help individuals confront and process difficult emotions, leading to lasting positive changes in mental health.
