Question to the Home Office:

To ask the Secretary of State for the Home Department, what evidence her Department uses to support the classification of psilocybin as a Class A drug.

The Government has not commissioned or published any recent analysis of the harms of psilocybin. Psilocybin, as an “ester of psilocin”, is controlled as a Class A drug under the Misuse of Drugs Act 1971 (the 1971 Act) and is placed in Schedule 1 to the Misuse of Drugs Regulations 2001. Psilocin is also subject to the United Nations Convention on Psychotropic Substances of 1971, to which the United Kingdom is signatory.

A number of drugs which have been controlled under the 1971 Act for a considerable period of time have not been subject to analysis or recent analysis of harm. The Advisory Council on the Misuse of Drugs regularly provides advice on the harms of drugs, and these are published on the gov.uk website.
