I apologize if anything I say has already been said, but the first few pages were redundant so I skipped ahead a bit.
Anywho, it is a pretty amazing drug, especially in the rave scene. However, you've got to watch out -- it has some pretty gnarly long term side effects. And that's just the MDMA base we're talking about. Today's pills are cut with arrays of chemicals; everything from speed to mescaline to meth. In fact, I recently read a report on the news that said over 50% of pills confiscated were tested positive for being cut with meth. Bad shit...
Also, if you think you're going to be able to match a pill to a website and know what the pill is cut with, think again... People change their recipes, stamp presses, etc, all the time. And the color is simply food coloring. Never rely on anyone but the [hopefully trustworthy] person you are getting them from.
I'm the type of person who doesn't have problems with addictions. I've used them on several occasions (fewer than 10 times) all at music events. (Global 2008 @ Redrocks CO was awesome! deadmau5!!!) However, I am aware of how useless I feel the next day and am not to fond of it.
And Benassi... Benny ol' boy... I had some of those orange Buddhas not to long ago (both the 1st gen and 2nd gen) here in Colorado. They were cut with a fuck load of caffeine. Had me going all night. Good stuff...
