Research into impaired cognitive performance related to drug misuse began at Edge Hill University (EHU) in 1998. It has predominantly concentrated upon impairments related to use of the illegal drug `ecstasy' (3,4-methylenedioxymethamphetamine: MDMA), although some has focussed upon cannabis related impairments in order to identify which of these drugs was related to a specific performance decrement. The impacts presented arise from contributions to policy development through the Advisory Council on the Misuse of Drugs (ACMD), the consultation response team of the British Psychological Society (BPS), media debate drawing upon our research, and through informing the design of a drug use prevention campaign.
A new, more structured way of assessing the various harms done to individuals, families, communities and wider society by a range of legal and illegal drugs was first articulated by Professor David Nutt and colleagues at the University of Bristol. The "rational scale" they developed in the light of their research has stimulated extensive policy debate and informed drug classification in the UK and overseas. The research underpinning the scale has been disseminated through numerous public lectures and discussions and has stimulated worldwide media coverage. As a consequence, public awareness of drug harms has increased and public engagement in important debates about drugs has intensified.
Research conducted by UEL's Drugs and Addictive Behaviours Research Group (DAB) and the UEL Institute for Research in Child Development (IRCD) from 1990-2012 has provided key information about the neuro-psychological risks of the use of the drug MDMA (Ecstasy).This information has been used by the US and UK governments, medical professionals and public information organisations. The research was included in the UK government Advisory Council on the Misuse of Drugs (ACMD, 2009) review of MDMA effects and informed government and public debate on the legal classification of MDMA. It has also supported associated debates around the potential harmful effects of MDMA. Subsequent media and public engagement with those debates has contributed to increased public awareness of the effects and risks of MDMA and engaged new audiences with important social and scientific issues. More recent research has informed parents and medical practitioners about the potential harmful effects of MDMA on specific aspects of infant functioning when taken during pregnancy.
Epilepsy, a condition that affects ca. 1% of the world's population, has severe clinical consequences; people with epilepsy (PWE) and poorly controlled seizures exhibit nearly an order of magnitude increase in premature death relative to the general population. About one-third of PWE do not benefit from treatment with currently approved medicines. Although historical evidence has suggested that cannabis might be useful in the control of epilepsy, work initiated by Drs Ben Whalley and Gary Stephens at University of Reading revealed that non-psychoactive components of cannabis can control epileptic seizures in animal models. This finding has led to a funded collaboration of ca £1.4M with GW Pharmaceuticals (UK) and Otsuka Pharmaceuticals (Japan) to establish a case for translation of two such components, cannabidiol (CBD) and cannabidavarin (CBDV), to human clinical drug trials. In particular, Reading research has resulted in GW trialling CBD (Phase 2, 50 participants, design stage) for a new indication of epilepsy treatment. A Phase 1 trial for CBDV (20 participants) began in July 2013, with a Phase 2 trial to begin immediately after successful completion of Phase 1. Results from the use of CBD on an open-label basis have shown major quality-of-life improvements for the patients concerned.
Research at the University of Aberdeen has directly contributed to the development of the cannabis-based medicine, Sativex®, which was licensed in the UK in 2010 for relieving neuropathic pain and spasticity of multiple sclerosis (MS), removing the need for patients to self-medicate with illegal, "unregulated" cannabis. The research has both enhanced patient welfare and promoted collaboration with industry. Several other countries have also approved Sativex®. Apart from such direct benefits, the research has also increased understanding of the benefits of cannabis-based medicines among the general public, and the main researcher has advised the Home Office on pertinent legislation. Therefore the claimed impact here includes benefits to health and welfare guidelines and on the public understanding of science. In addition industry has invested in research and development and a new product has been commercialised.
The health of people who inject illicit drugs, the formulation of harm-reduction policies, and the work of associated businesses and social enterprises have all benefited from the University's laboratory and practice research into the safety and efficacy of materials and equipment used in needle-exchange programmes. The research has informed the development of safer acids for injection preparation, safer injecting paraphernalia (e.g., spoons and filters) and an information film which has been distributed from needle exchanges on DVD and viewed over 50,000 times online. The research has led to enhanced support and protection for injecting drug misusers, and to advances in harm reduction in the UK, France and Canada.
Cardiff University research quantifying the association between cannabis use and increased risk of psychosis has transformed the global debate on cannabis use and continues to shape governmental policies, guidelines and public attitude internationally. Cardiff's findings regarding the effects of cannabis use on mental health are both widely cited in the media and commonly used worldwide as information sources when delivering public health educational material. Cardiff research demonstrated that cannabis use is the only individual-specific, modifiable risk factor known for schizophrenia. Results were used to calculate that, in the UK alone, approximately 15% of cases of schizophrenia are preventable if cannabis were to be eliminated from the population.
A routine test to screen for patients genetically disposed to serious side effects from treatment with thiopurine drugs has been widely adopted following research by the Academic Unit of Clinical Pharmacology at the University of Sheffield. The test has spared patients painful and potentially life-threatening sepsis, and saved the considerable associated treatment costs which have been estimated to be over £9,000 per patient for a 17 day hospital stay. It has also led directly to a change in clinical guidelines and recommendations in both the USA and UK.
Research by Professor Abdul Basit's group at the UCL School of Pharmacy is leading to improved treatments for ulcerative colitis and other conditions through increased knowledge of the complex physiology of the gastrointestinal tract. Improved understanding of in vivo drug release and uptake has allowed development of three patent-protected technologies for improved drug delivery: PHLORALTM, for release of drugs in the colon, and DuoCoatTM and ProReleaseTM formulations designed to allow intact transit through the stomach followed by immediate release upon gastric emptying. These technologies are the subject of licences and ongoing development programmes, with PHLORALTM currently in phase III clinical trials. The impact is therefore the introduction of enabling technologies that have positively influenced the drug development programmes of pharmaceutical companies.
Research at the University of Sheffield developed pharmacokinetic tools that enable prediction of drug absorption, distribution, metabolism and excretion, and potential drug-drug interactions. In 2001 the University created a spinout company, Simcyp Ltd, to commercialise the technology. The impacts are:
