Psychedelics

Psychedelic drugs are a subclass of hallucinogenic drugs that trigger non-ordinary mental states and a perceived "expansion of consciousness". They generally cause specific psychological, visual, and auditory changes and a substantially altered state of consciousness. Classic psychedelics include mescaline, LSD, psilocybin, and DMT, which are part of the tryptamines, phenethylamines, or lysergamides families of chemical compounds and act via serotonin 2A receptor agonism. The exact nature of how psychedelics induce changes in perception and cognition is still unknown, but the psychedelic experience is often compared to non-ordinary forms of consciousness such as those experienced in meditation, mystical experiences, and near-death experiences. Many psychedelic drugs are illegal, but recreational use is common and research has shown that psychedelics are physiologically safe and rarely lead to addiction, with some studies suggesting they could be effective treatments for certain forms of psychopathology.learn more on wikipedia
