Just for fun? No. I do it professionally.
You really worded that question strangely.
But yeah man I've done and loved most of them that you've heard of, with the exceptions of ketamine and PCP.
Anyone who is going to do E, make sure you're in a positive environment. Even more so than with acid and mushrooms. While it is impossible (almost) to have a "bad trip" on ecstasy, you can actually cause long-term psychological problems if you do it in the wrong atmosphere. It breaks down psychological barriers, which is why psychiatrists used to love giving it to patients during counseling sessions. If these barriers come down and you're in the wrong place, it could be bad news.
Great drug, though. The first dozen times or so at least.
