The legal status of psilocybin shrooms varies by country, state, and region. In most places, psilocybin mushrooms are illegal to possess, cultivate, or sell, and can result in fines or imprisonment. However, some places have decriminalized or legalized them for medical, religious, or personal use. For example, in the United States, psilocybin is classified as Schedule I drug under federal law, meaning they have no accepted medical use and a high potential for abuse. However, some states and cities such as Oregon, Colorado, California, and Washington D.C. have decriminalized or legalized their use for certain purposes. It is essential to check the local laws and regulations before using psilocybin to avoid legal trouble.
