WASHINGTON (AP) - A prestigious scientific journal is retracting a study about the effects of the drug Ecstasy on the brain because the animals used in the research were given a different drug.
The researchers blamed the error on a labelling mix-up. Previous studies had reported on the brain hazards of Ecstasy, and the researchers said the problems with their study did not call into question the earlier ones.
Scientists at Johns Hopkins University reported in September 2002 that key neurons in the brains of squirrel monkeys and baboons were damaged when the animals were given doses of Ecstasy that mimicked those often taken by users of the drug during all-night dance parties.
The researchers said the study raised questions about whether Ecstasy - also known as MDMA - might hasten the onset of Parkinson's disease, a disorder triggered by the permanent loss of dopamine-producing nerve cells. It was those nerve cells that were reported to have been damaged by Ecstasy in the Johns Hopkins research.
In retracting the story, the journal Science said Friday that the researchers discovered that labels on drugs supplied to them by an outside company were incorrect and the animals had actually been given a different drug, methamphetamine.
Methamphetamine would be expected to produce the brain damage seen in the animals, the researchers said in their retraction.
Ecstasy is methylenedioxymetham phetamine. Both are forms of amphetamine but with different added chemicals and chemical action, said researcher Dr. Una McCann.
She explained that a bottle of MDMA and a bottle of methamphetamine were delivered to the lab the same day, from the same supplier, for different research purposes.
When the researchers had trouble duplicating some of their work they began to suspect problems, she explained. They had the bottle labelled methamphetamine analysed by three labs and all reported it was pure MDMA - and the brains of two animals that had died following the experiment were found to contain methamphetamine, not MDMA.
"It's a difficult situation . . . We pick up where we left off and see what we can do to prevent this from happening again, and we correct the record," McCann said.
She said the laboratory has developed a test for use in future studies to make sure it is using the actual drug that the research calls for.

Three dangerous bills are the RAVE Act (H.R. 718), the CLEAN-UP Act (H.R. 834), and the Illicit Drugs Anti-Proliferation Act (S. 226). While aimed at the very real problem of substance abuse, the bills go too far by punishing business owners for the drug offenses of their customers and threatening to shut down concerts, circuit parties, dance clubs, and other forms of entertainment. Business owners could be jailed for enacting health measures that save lives - such as teaching their staff first-aid. You could even go to jail for 20 years for throwing a party in your own home.
