Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, if he will make an estimate of the annual cost of cannabis-related health conditions to the NHS.

The Department is committed to reducing the harm from all illicit drugs. Any illegal drug use, including cannabis, can be harmful, both from immediate side-effects and long-term physical and mental health problems. It can, for some, have a negative impact on their fertility. Cannabis use can contribute to and exacerbate existing mental health problems or can accelerate their development in people predisposed to mental health problems.

No estimate has been made of the annual cost to the National Health Service specifically of cannabis-related health conditions or the impact of cannabis-related mental health conditions on NHS finances. An assessment cannot be accurately made because the data relating to cannabis and mental health related health conditions and admissions is presented across various settings. The diagnosis code for ‘mental and behavioural disorders due to use of cannabinoids’ does not include admissions to mental health hospitals or cannabis-related treatment occurring outside of a hospital setting.

Dame Carol Black’s review of evidence related to drugs, published in February 2020, estimated the cost to the NHS of illegal drug use, not substance specific, at £431 million per annum. This includes admissions in secondary care, prison treatment and infectious disease. However, this figure does not include other NHS costs such as primary care or accident & emergency usage so will be an underestimate.
