Researching the Harmful Effects of Continued Illegal Drug Use

It is widely accepted that continued use of illegal drugs can have many negative effects on users, but when people ask ‘Exactly what harm do they cause?' it can still be unclear and difficult to answer definitively.

To try and find answers to this, as well as other questions, Philip Murphy from Edge Hill University's Psychology team is currently undertaking research into impaired cognitive performance and mood disturbances related to the use of cannabis and ecstasy (MDMA).  

"My work predominantly involves the laboratory testing of cognitive performance on computer-based tasks," explains Philip. "These tasks utilise the same processes as those used in everyday activities, but the laboratory setting allows for precision in the recording of performance."  

Because both cannabis and ecstasy are widely used in the UK, the findings of Philip's research could have implications for thousands of people and he hopes that, with an increased understanding of their harmful effects, a decrease in their usage will then follow.  

"Apart from the obvious benefits of helping people to see the dangers these drugs cause, my research also directly benefits students here at Edge Hill,  with final year psychology students using appropriate examples from my research all the time via the ‘Addiction Studies' module that I teach."  

Philip considers it only right that students should be taught by people who are contributing to the development of their discipline through their research and writing,  firmly believing it is through this that students obtain a full university experience.  

The need for useful and valuable research is something Philip feels passionate about and he explains further: "Research is a fundamental function within any university and the knowledge it provides is part of what we offer to society as a whole. Research feeds into policy development and general community awareness - contributing to public life. As well as this it enhances that standing of a university and strengthens its teaching role."  

Philip has been engaged in drug misuse research since 1986 and has published his findings widely, with several new publications currently in preparation. As is common across science, in addition to producing original research, Philip also reviews findings from other researchers across his field of work.
