Users can come to the attention of the legal system due to possession, intoxication, or criminal behavior that occurred after ingestion of the mushrooms. The active drug in these mushrooms is called psilocybin, which is chemically related to Lysergic Acid Diethylamide (LSD). It has a long history of being used in religious rituals in Mexico and Central America. Users are typically teenagers and young adults and it is not known to cause physical dependency. Many users attempt to gather mushrooms themselves, leading to dire results as misidentification of mushrooms can have serious consequences. In this way, poisonous mushrooms have been mistakenly ingested by users resulting in illness and death.
