I enjoy MDMA (amongst many other things in life), but it causes problems for me. I'm kind of a shut in, the few friends I have are a bit distant because I tend to get clingy, and when I realize it then I apologize profusely which is quite annoying I suspect. On MDMA this aspect of my personality multiplies tenfold. I become incredibly friendly and, almost.. loving to everyone. While sober I maintain a deep love for all living things because I understand that we're all fighting the same battle, but on MDMA this love explodes and rains down upon everyone around me. Of course I've only ever exposed myself to strangers on it for fear of totally disgusting my "friends", so I'm not sure how the strangers felt about it. But in my own mind, I was being annoying.
The come down from MDMA is pretty terrible. Not the worst I've had, but fairly bad. I suppose the amount you take makes all the difference.
As for my general view on drugs, as if it matters or anybody cares aside from myself:
I really don't see the problem with people taking drugs as long as they aren't putting others in danger, or causing damage to other peoples' property. Do you know why house cats lie on their backs and look at their owners upside-down? A lot of people claim that it's a perspective thing. They're getting new, interesting sensory input by looking at the world upside down.
That's what I think of when I imagine humans ingesting mind-altering chemicals. We're changing our perspectives. We're trying to learn. Yes, some people become addicted to the sensory input and get stuck in a painful loop, but that's just the way it is. Why cause friction by shunning such an understandable act? We all want to learn, after all. Some of us look to the stars, some look to the earth, and some look within. But drugs open up a whole new set of ways for us to do that.
Either way, I guess it's all natural. Being in favor, not being in favor, downright hating people who take drugs, it's all just a part of our world.
