Well I also have an opinion about it, and I happen to love MDMA. If it's pure, it's safe and maybe the most enjoyable experience I've ever had. Count me as one of the people that says go for it.

By the way, what circumstances are these? I like it best with just a few friends and some music, a rave scene would not be for me.

Also, if you don't eat for like 24 hours before you do it, it gets REALLY heavy on you (found this shit out the other day).

But yeah, I'd say a decent sociable situation is perfect. If you dig raves, go raving. If not.... don't go raving.
