check out the vaults at
www.erowid.org under ecstacy or mdma for tons of good info on "ecstacy".
www.ecstacydata.org is also good, they publish results of testing various samples of ecstacy to find out what's really in them (no doubt the biggest danger in taking ecstacy is that it is often adulterated with other chemicals esp.
methamphetamine or dxm, and infact may contain no mdma at all). also check out info on PMA, a close chemical cousin of mdma which has been the culprit in many of the "ecstacy deaths' reported in the media.
