We've been debating why for hundreds of pages (
First discussion here.
Second discussion here. See the second post in the second discussion for a nice summary of the discussion so far). Summarized, we have no idea. Could be that something changed in the process of making MDMA. Could be that there are certain impurities that are in play. In some cases it could indeed be cut MDMA. Could be because of a very technical, chemical reason. Or it could be a different reason entirely. There are also a lot of people that hold the opinion it's due to something that changed in the people themselves by using it too often. But there are a lot of people like you that are relatively new to it and have the same experience. I was firmly in the camp of "it's something with the people themselves and with myself" up until
a certain experience a few years ago that completely changed my perspective on it, comparable to your experience. The thing is, a lot of people are experiencing this difference with MDMA 10-15 years ago. We have no idea why. But the fact of the matter is that when I started using MDMA 20 years ago, all MDMA (or better said, all MDMA experiences) was like you describe and if I would have gotten the experience that is mainstream these days from a batch I bought back then, I would have thrown it in the trash and given the person I bought it from an earful. The MDMA of back then changed me as a person and everyone around me as well, for the better, it changed my outlook on life and helped me get out of a dark path I was on. I really miss it. Don't get me wrong, my experiences these days are still
very enjoyable but for different reasons and much less earth-shatteringly, mindblowingly, otherworldly amazing. It's exactly like you say, like it's two different drugs
