They Said Half a Hit of Ecstasy Would be Fun....

After seeing this Anti-ecstasy PSA on I was just over at a pro-ecstasy forum to see if this is really the case.  Its actually ridiculous to me.  In the same sentence people were saying how the xtc made them feel all fantastic or whatever, and at the same time were saying that it makes them soil themselves and vomit all over the place.

I really don't get it.  Can someone enlighten me?
