Hallucinogens are a class of drugs that alter perception, mood, and cognition by disrupting the way the brain processes information. These substances can cause vivid hallucinations, sensory distortions, and an altered sense of time and self. While some hallucinogens are derived from natural sources (such as psilocybin mushrooms), others are synthetic (such as LSD and PCP).
Although hallucinogens are often thought of as non-addictive, repeated use can lead to psychological dependence, persistent hallucinations, and severe mental health disturbances. Some hallucinogens, like PCP and ketamine, also have physically addictive properties, increasing the risk of abuse.
