Y49.6: Psychodysleptics [hallucinogens]

Psychodysleptics, also known as hallucinogens, are a category of substances that primarily alter perception, thought processes, and mood. Exposure to these substances often results in people experiencing vivid visual or auditory hallucinations, or seeing, hearing, or feeling things that aren't really there. While the exact mechanisms of how these substances work are not entirely known, they are believed to disrupt the normal functioning of the brain's serotonin receptors. The onset of symptoms, which might include distorted sensory perception, emotional changes, and cognitive alteration, usually occurs shortly after intake and may last for a few hours to several days. Although physical addiction to these substances is not common, repeated use might lead to a psychological dependence. Long-term use can potentially result in persistent psychological disturbances. Other risks associated with the use of psychodysleptics may include accidents or injuries due to altered perception, and worsening of underlying mental health conditions.
