Before you go out and put too much trust in that peer-reviewed scientific research that just came out last Friday, take into consideration this report from the New York Times about a study released previously this year concerning death rates and the designer drug, Ecstasy.
There was, according to the Times article, substantial complaining at the time about the study by other scientists working on ecstasy research because it just didn't conform to what they were seeing. However, the journal published it anyway.
Last week, the scientists who did the study retracted it because they discovered that they had not injected the chimpanzees with ecstasy at all, but with a powerful amphetamine.
Oops! Perhaps they should have checked the labels on the chemicals before publishing, eh?
