This study was a double-blind, placebo-controlled investigation of the cognitive and brain activation effects of the isomers of MDE. The researchers concluded “The so-called entactogenic effects of MDE are likely to be caused by the (S)-enantiomer, whereas (R)-MDE appears to be responsible for neurotoxic effect.”
