Question to the Home Office:

To ask the Secretary of State for the Home Department, pursuant to the Answer of 7 June 2021 to Question 7725 which noted that a number of controlled drugs have not been subject to analysis or recent analysis of harm, if she will take steps to commission a comprehensive review of the relative harms of controlled drugs to ensure that the UK drug classification and scheduling systems are consistent with the latest scientific and medical evidence available.

The Government has no plans to commission a comprehensive review of the relative harms of controlled drugs. The Government takes expert advice from the Advisory Council on the Misuse of Drugs (ACMD) on classification of substances under the Misuse of Drugs Act 1971 and scheduling under the Misuse of Drugs Regulations 2001.

The Government commissions the ACMD to consider classification and scheduling of substances if, for example, new evidence about harms or legitimate uses emerges or there are issues of public concern. With regard to the scheduling of controlled drugs, the Misuse of Drugs Regulations 2001 exempts specified activities from the scope of the offences, for example, where controlled drugs are produced and supplied by healthcare professionals for medicinal purposes. The Home Secretary places controlled drugs in the appropriate schedule following consideration of advice from the ACMD. There is an established process for the development of medicines, overseen by the Medicines and Healthcare products Regulatory Agency (MHRA), which enables medicines containing controlled drugs to be developed, evaluated in clinical trials and licensed based on an assessment of their quality, safety and efficacy before being made available to patients in the UK. When a medicine containing controlled drugs is made available following an MHRA assessment, it may be scheduled or re-scheduled under the 2001 Regulations as appropriate, following consideration of advice provided by the ACMD.
