(2) what criteria were used for the classification of (a) psilocin and (b) psilocybin as class A drugs;
(3) how many deaths have been caused by (a) psilocin and (b) psilocybin in each of the last 10 years.
The classification of psilocin and psilocybin has not been reviewed by the Advisory Council on the Misuse of Drugs. The classification of psilocin and psilocybin as Class A drugs under the Misuse of Drugs Act 1971, since that Act came into force on 1 July 1973, reflects the United Kingdom’s implementation of the United Nations Convention on Psychotropic Substances 1971. Psilocin and psilocybin (and many similar drugs) were included in Schedule one to the 1971 Convention, reflecting international consensus that these substances should be subject to the highest level of control. HM Government placed these substances in Part I of Schedule two to the 1971 Act as Class A drugs. The information on deaths from psilocin and psilocybin is not held.
