I think it depends on the user. Like Clocktower said (since I remember discussing this with some posters a few months ago who provided solid information on why/how the "magic" can be regained, at least for some people), some people keep it but I think some do not. Now, I know what everyone's thinking, but I'm going to flat out say that I'm NOT an outlier, especially from my days as a hardcore roller; it's a lot more common than people think. I've even met a girl who is known to have one of the best lightshow skills around my area, and she admitted dropping mdma everyday for I don't know how long exactly, but not simply like weeks or something. From the few times I met her, she seems completely fine and obviously fully functional too (not a surprise). I'm just probably the only recent knucklehead that readily admits it on a HR forum. She isn't the only example either, but being a mod here, I simply won't go into much more detail like I would have when I was BLer (and I could go all out, heh, you guys are lucky to have that freedom). Simply put, I have a lot of personal experience with this, and that's really what I mainly bring to the table here at MED. Although, I'm going to always advise that it is a bad idea, and IF one were to even consider this, make damn sure you react extremely positively to mdma and know how to handle yourself on it.
My first time was absolutely out of this world; nothing ever came close to it. I feel like MDMA should never be underestimated the first time, or the first few initial times. In relation to how un-sober you are, for my first time it was on par with all of these; 8mg DOPr, 150mg miprocin, 2g's of shrooms (first time) + weed and 50mg of aMT. In other words, my first time was on par (albeit in a very different and clearheaded type of way) to hardcore ego-shattering psychedelic experiences. It's just that there isn't any ego loss and the effects are completely different. Nothing is really that distorted, but instead everything is magnified to the extreme. Sounds, colors, brightness, touch, emotions, thoughts and feelings which all exuded an extreme amount of positivity, not unlike how I felt @ Grad Night in high school except x 100. I still remember this, which I think I openly talked about with KOB back in the old 5 mapb thread, but I took a single pill (which should've only been 100mg or less) and was hanging out with some friends at the time, sitting while playing an arcade fighting game (called mvc2). About half an hour after I dropped it, I felt this massive rush and warmth feeling inside, building up massively, and there were some guys playing a racing game, and the car's sound of 'Vrooooom!' was so loud and clear, which basically echoed from one side of my ear to the other. And it literally hit me like a ton of bricks; massive euphoria, sweaty palms, a super strong body high which was felt the most at the back of my head, and nystagmus so bad that I just let go of the joystick and literally could not play anymore (and sadly, I spent many hours playing this game so I'm really good at it). But I felt like an infant in the way that I just wasn't able to play in that condition. So I get up to go outside to smoke a cig, and I noticed that the body buzz was so extreme that it felt awesome just walking in my shoes and feeling my shirt touch my arms, things like that. Even pulling out my cig felt good, and especially smoking it. Right away, I go outside and lit up my cig, and just stared at a tree for idk how long, but it just looked the same as it always does except it was bright, beautiful and more vibrant than I've ever seen; like it was just brimming with life. All of the details could be seen far away, and I didn't care that my friends thought I was super weird staring at it, because that's just what I wanted to do at the time.
Hmm, I could go on, but obviously none of my experiences afterwards ever came close to this level of an effect. Maybe like 75% of this strength at most. I was with a bunch of friends too, especially one of them who had a vast experience with rolling that I trusted at the time, so I felt completely at ease. If the set and setting wasn't that fabulous, then I don't know how I would've reacted to such extreme effects. Even then, I did feel some anxiety because it was so strong and unlike anything I was expecting. I had already taken lsd quite a few times before then, but the effects are almost like polar opposites except for the general euphoria and feeling of knowing that you're not sober. MDMA is extremely empathogenic and with the help of weed, the effects stayed strong even until the next day, when I still had nystagmus, sweaty palms, empathic energy, elevated senses and inability to eat or sleep specifically. It's a slang term, but I still had cotton mouth where it was too difficult to eat anything because of a lack of saliva, even after drinking water.
Anyway, it was a wonderful experience that was never repeated in intensity again. It was after this, and before my splurges, when I started reaping the benefits of MDMA use through its ability to "force" happiness, positive thinking, looking back at traumatic experiences rationally in an "open arms" type of way and believing in myself and "the ways of life." If it wasn't for this, I would've never been able to reach and get through to my mom and dad after everything that happened; and all I did was put myself in their position and thought about how they might have been feeling during that time too, and especially that's how I reached out to my dad the most. (Besides, the timing is NOT a coincidence). Real, genuine empathy which not only had they taught me, but mdma solidified it for me to the point where I know I no longer have any progression to make on this front. Some people IRL could never understand, but given what happened to me personally, this benefit far exceeds anything that I might (most likely not) have gotten negatively from my use.
Edit: So make sure you cherish your first few times and optimize your set and setting! You might be like me where it never happens again. Trust me, I actually used to be sad about that (which is why I used it that way before) but obviously I'm over it now. If people are sensitive, I urge them to take LESS and to never take it alone unless you had prior, good experiences doing that. Otherwise, it might not have positive effects because MDMA can and will amplify your mood and state, whether positive or negative. Trying it with someone who is experienced is really the best option, especially your first few times.
