Three British psychologists said ecstasy did not cause long-term health problems contrary to a vast volume of studies. Responding, Grainne Kenny of Europe Against Drugs said: "The studies are there and show ecstasy causes brain damage and depression and those studies have been very carefully done." Dr Jim Donovan of the State Forensic Science Laboratory said ecstasy damaged the production of serotonin the chemical that gives the 'feel good' experience. Serotonin is a neurotransmitter which regulates calm and well-bring and is also thought to influence cognition, appetite, movement and body temperature. Animal research has indicated ecstasy damages the ability to produce serotonin, thereby resulting in the risk of depression. The paper by the three psychologists said the changes to serotonin caused by ecstasy involved the degeneration of nerve fibres, which can be regrown, and not the cell themselves. The psychologists, Dr John Cole and Harry Sumnall in Liverpool University and Prof Charles Grob, director of Child and Adolescent Psychiatry at the Harbour-UCLA Medical Centre in California, said data was being used selectively to support findings that ecstasy caused brain damage. Writing in The Psychologist, the magazine of the British Psychological Society, they accused researchers of bias and of minimising date suggesting ecstasy had no long-term damage. They said although many studies on volunteers had been carried out, those that showed no damage were ignored. Many international experts dismissed the article, among them Dr Rodney Croft of the Swinburne University of Technology in Victoria, Australia. He said: "There is strong converging evidence that ecstasy does cause impairment. "The strength of this evidence makes 'danger' the most reasonable message to be broadcasting. - --- MAP posted-by: Alex
