Question to the Home Office:

To ask the Secretary of State for the Home Department, how many people have been arrested for possession of (a) psilocybin, (b) psilocin and (c) magic mushrooms in each of the last five years.

The Home Office collects and publishes data annually on arrests in England and Wales, available here: Police powers and procedures: Stop and search and arrests, England and Wales, year ending 31 March 2022 - GOV.UK (www.gov.uk)

However, this data is collected by wider offence group, e.g. “drug offences”, therefore data on arrests for more specific drug offences is not available.
