Valerie Curran of University College, London, says the drug's after-effects are worse than those of drink. The melancholia that grips Ecstasy users is deeper, takes several days to appear and lasts longer, she told the New Scientist. Two other unpublished studies have unearthed evidence indicting Ecstasy as a memory-marauder. In most memory tests, Ecstasy users did almost twice as badly as alcohol users. Several days after a night out clubbing, regular Ecstasy users typically recalled about 30 per cent fewer words than those who had never taken the drug. But most importantly, Ecstasy users have much longer depression-spells than alcoholics. While the drinkers snapped out of it by Wednesday, Ecstasy users had slid deeper into depression. Many would have qualified for anti-depressants, says Curran.
