There is clear scientific and medical evidence that cannabis is a harmful drug which can damage people’s mental and physical health, and harms individuals and communities.

The evidence from the Government’s independent experts, the Advisory Council on the Misuse of Drugs (ACMD), is that the use of cannabis is a “significant public health issue and can unquestionably cause harm to individuals and society”. The ACMD’s most recent advice on cannabis is set out in its 2008 report - https://www.gov.uk/government/publications/acmd-cannabis-classification-and-public-health-2008.

The Government is aware of different approaches being taken abroad and of the associated debates. However, it may be years before we can fully understand the effect on public health and crime as a result of the decisions to legalise and regulate the production, supply and possession of cannabis as data on harms, benefits and revenues will take some time to gather.

The Government believes that the legalisation of cannabis would send the wrong message to the vast majority of people who do not take drugs, especially young and vulnerable people, with the potential grave risk of increased misuse of drugs.

We take a broad approach to prevention, supporting investment in a range of programmes, which have a positive effect on young people and adults, giving them the confidence, resilience and risk management skills to resist drug misuse.

Cannabis use has continued to drop in the last decade, with 6.5 per cent of 16 to 59 year olds having taken it in 2015/16 according to the latest Crime Survey for England and Wales. This is a drop from 8.7 per cent in 2005/06.

Where claims are made for medicinal applications, there is a clear regime in place. This is administered by the Medicines and Healthcare products Regulatory Agency (MHRA) and enables medicines (including those containing controlled drugs) to be developed, licensed and made available for medicinal use to patients in the UK. For example, the cannabis-based medicine ‘Sativex’ has been granted marketing authorisation in the UK by the MHRA for the treatment of spasticity due to multiple sclerosis. Sativex was rigorously tested for its safety and efficacy before receiving approval.

The MHRA is open to considering marketing approval applications for other medicinal cannabis products, should a product be developed. As happened in the case of sativex in 2010, the Home Office will consider issuing a licence to enable trials of any new medicine providing it complies with appropriate ethical approvals. Medicinal products must have a product licence (marketing authorisation) before they can be legally sold, supplied or advertised in the UK, unless exempt. Licensed medicinal products have to meet safety, quality and efficacy standards to protect public health.

Cannabis and any cannabis products should be subjected to the same regulatory framework that applies to all medicines in the UK. To do otherwise will amount to a circumvention of the clearly established regime for approving medicines in the UK.
