The legal status of psilocybin mushrooms varies across countries and jurisdictions. Here is a general overview of their legal status around the world: Illegal: Psilocybin mushrooms are illegal in many countries, including the United States, Canada, Australia, the United Kingdom, and most countries in Europe. In these jurisdictions, the possession, cultivation, sale, or distribution of psilocybin mushrooms is considered a criminal offense. Decriminalized: Some countries, states, or cities have decriminalized the possession and personal use of psilocybin mushrooms. Decriminalization typically means that the possession of small amounts of psilocybin mushrooms is treated as a minor offense or a civil infraction, often resulting in a fine or alternative penalty rather than criminal charges. Examples of jurisdictions that have decriminalized psilocybin mushrooms include Portugal, Brazil, the cities of Denver and Oakland in the United States, and the Canadian cities of Vancouver and Victoria
