Department of Health had any plans to conduct research into the long-term effects of benzodiazepines, the Department replied, saying they have no plans to do so, as benzodiazepines are already restricted to short-term use and monitored by regulatory bodies. In a House of Commons debate, Phil Woolas claimed that there had been a cover-up of problems associated with benzodiazepines because they are of too large of a scale for governments, regulatory bodies, and the pharmaceutical industry to deal with. John Hutton stated in response that the Department of Health took the problems of benzodiazepines extremely seriously and was not sweeping the issue under the carpet. In 2010, the All-Party Parliamentary Group on Involuntary Tranquilliser Addiction filed a complaint with the Equality and Human Rights Commission under the Disability Discrimination Act 1995 against the Department of Health and the Department for Work and Pensions alleging discrimation against people with a benzodiazepine prescription drug dependence as a result of denial of specialised treatment services, exclusion from medical treatment, non-recognition of the protracted benzodiazepine withdrawal syndrome, as well as denial of rehabilitation and back-to-work schemes.

The complaint alleged that the discrimination is deliberate, large scale and that government departments are aware of what they are doing. Declassified Medical Research Council meeting The Medical Research Council (UK) held a closed meeting among top UK medical doctors and representatives from the pharmaceutical industry between the dates of 30 October 1980 and 3 April 1981. The meeting was classified under the Public Records Act 1958 until 2014 but became available in 2005 as a result of the Freedom of Information Act. The meeting was called due to concerns that 10–100,000 people could be dependent; meeting chairman Professor Malcolm Lader later revised this estimate to include approximately half a million members of the British public suspected of being dependent on therapeutic dose levels of benzodiazepines, with about half of those on long-term benzodiazepines. It was reported that benzodiazepines may be the third- or fourth-largest drug problem in the UK (the largest being alcohol and tobacco). The Chairman of the meeting followed up after the meeting with additional information, which was forwarded to the Medical Research Council neuroscience board, raising concerns regarding tests that
