The legal status of psilocybin mushrooms varies world-wide. Psilocybin and psilocin are listed as Schedule I drugs under the United Nations 1971 Convention on Psychotropic Substances. Schedule I drugs are defined as drugs with a high potential for abuse or drugs that have no recognized medical uses. However, psilocybin mushrooms have had numerous medicinal and religious uses in dozens of cultures throughout history and have a significantly lower potential for abuse than other Schedule I drugs.
Psilocybin mushrooms are not regulated by UN treaties. From a letter, dated 13 September 2001, from Herbert Schaepe, Secretary of the UN International Narcotics Control Board, to the Dutch Ministry of Health:
As you are aware, mushrooms containing the above substances are collected and used for their hallucinogenic effects. As a matter of international law, no plants (natural material) containing psilocine and psilocybin are at present controlled under the Convention on Psychotropic Substances of 1971. Consequently, preparations made of these plants are not under international control and, therefore, not subject of the articles of the 1971 Convention [emphasis added]. Criminal cases are decided with reference to domestic law, which may otherwise provide for controls over mushrooms containing psilocine and psilocybin. As the Board can only speak as to the contours of the international drug conventions, I am unable to provide an opinion on the litigation in question.
Many countries, however, have some level of regulation or prohibition of psilocybin mushrooms (for example, the US Psychotropic Substances Act, the UK Misuse of Drugs Act 1971, and the Canadian Controlled Drugs and Substances Act). The prohibition of psilocybin mushrooms has come under criticism, from the general public and from researchers who see therapeutic potential with regard to drug addictions and other mental instabilities, such as PTSD. Among regulated drugs, psilocybin mushrooms have relatively few medical risks.
In many national, state, and provincial drug laws, there is a great deal of ambiguity about the legal status of psilocybin mushrooms, as well as a strong element of selective enforcement in some places. The legal status of Psilocybe spores is even more ambiguous, as the spores contain neither psilocybin nor psilocin, and hence are not illegal to sell or possess in many jurisdictions, though many jurisdictions will prosecute under broader laws prohibiting items that are used in drug manufacture. A few jurisdictions (such as the US states of Georgia and Idaho) have specifically prohibited the sale and possession of psilocybin mushroom spores. Cultivation of psilocybin mushrooms is considered drug manufacture in most jurisdictions and is often severely penalized, though some countries and one US state have ruled that growing psilocybin mushrooms does not qualify as "manufacturing" a controlled substance.
