Hopkins says ecstasy study was incorrect
By Christopher Jones | September 9, 2003A Johns Hopkins University study claiming that users of MDMA, the drug popularly know as ecstasy, could suffer from permanent brain damage has been completely retracted after its authors discovered that another drug was accidentally used in the study. According to the retraction written by the Hopkins researchers, "the drug used to treat all but one animal in [the original study] came from a bottle that contained d-methamphetamine instead of the intended drug, racemic MDMA." Researchers attributed the mix-up to an error in labeling by the company that supplied the MDMA. The study, published in the September 27, 2002 issue of Science magazine, concluded that even occasional use of ecstasy could cause irreparable brain damage.
