Past research has attributed at least part of the "love effect" of Ecstasy to an increase in brain levels of the natural anti¬depressant serotonin. Australian neuropharmacologist lain Mc¬Gregor, of the University of Syd¬ney, has another explanation. He says Ecstasy users are under the influence of a massive surge of oxytocin-the brain's "love" hormone, normally released dur¬ing nursing or orgasm-which cements pair bonds.
Earlier research had shown that Ecstasy causes an increase in blood levels of oxytocin, but because the hormone doesn't readily cross the blood-brain barrier, no one was certain whether it was responsible for the feelings of empathy, eupho¬ria, and openness reported by users. After giving rats the hu¬man equivalent of two to three Ecstasy tablets, McGregor found that the drug activated oxytocin-containing neurons in the hypothalamus, the part of the brain that normally releases the hormone. Moreover, when McGregor then gave the rats an oxytocin blocker, the Ecstasy¬induced social behavior-lying next to each other and cud¬dling-ail but disappeared.
So just how long might an Ecstasy-instigated relationship last? "There was an old bumper sticker in California that said 'Don't get married for 6 months after Ecstasy' -that could be the approximate length of time, but who knows?" McGregor says. A more specific answer could be coming soon: Mc¬Gregor is currently devising an experiment to test whether rats prefer to be with rats they've taken Ecstasy with.
