Retracted Article On Dopaminergic Neurotoxicity of MDMA - Original Publication

Original Publication

The Ricaurte article was published in the middle of a group of 16 "reports" and not given special prominence in the "Highlights of research in this issue" section of the 27 September 2002 issue of Science. The short editorial commentary on the article was called "More Dangers from Designer Drugs" and drew the reader's attention to previously published research indicating that "ecstasy" use alters serotoninergic synaptic transmission. Science also commented that by linking "ecstasy" to dopaminergic neurotoxicity in monkeys, the Ricaurte article suggested that recreational users of "ecstasy" might be putting themselves at risk for developing neuropsychiatric disorders (such as Parkinson's disease) that are related to dopamine dysfunction.

The Science section called "News of the Week" in the 27 September 2002 issue had an article by reporter Constance Holden called, "Drug Find Could Give Ravers the Jitters" (on pages 2185-2187). This news coverage did give some special prominence to the Ricaurte article. The Holden commentary stressed that the Ricaurte article was part of an active scientific controversy about the ability of "ecstasy" to cause permanent brain damage in human recreational drug users. This news article included a section with speculation from Ricaurte trying to justify why other researchers fail to observe ecstasy-induced dopaminergic neurotoxicity. Jon Cole of the University of Liverpool explained that the results on dopaminergic neurotoxicity in the Ricaurte article were a big surprise and was quoted as saying, "The entire human literature relies on the notion that MDMA is a selective serotonergic neurotoxin."

    Orson Welles (1915–1985)

    I would rather have as my patron a host of anonymous citizens digging into their own pockets for the price of a book or a magazine than a small body of enlightened and responsible men administering public funds. I would rather chance my personal vision of truth striking home here and there in the chaos of publication that exists than attempt to filter it through a few sets of official, honorably public-spirited scruples.
    John Updike (b. 1932)
