Hallucinogens are powerful drugs that can alter a person’s perceptions of reality. Common types include LSD, psilocybin mushrooms, DMT, and peyote. These drugs can induce vivid sensory experiences that can be difficult to distinguish from reality. Researchers have shown interest in the potential therapeutic use of hallucinogens for conditions like depression and PTSD. However, the use of hallucinogens can also come with risks, such as bad trips, anxiety, and paranoia.
