HC Deb 08 July 1981 vol 8 c127W
Mr. Alton

asked the Secretary of State for the Home Department if he is satisfied with the state of the law governing the cultivation of psilocybin.

Mr. Raison

Yes. The psilocybin mushroom grows naturally in this country; a prohibition on its deliberate cultivation would therefore serve little purpose and be difficult to enforce. The preparation of these mushrooms to obtain the drug psilocin without a licence would be an offence under the Misuse of Drugs Act 1971.
