Ismene, please read & respond. I have worked quite some wonders in remaining respecful throughout this whole post, please repay my kindness.
You havn't even read the study have you.
I wonder if
you actually have read the study, and by this I do
not mean the Guardian article, but the original study. You were talking about (and I quote)
do you think they studied hundreds of people
while they only studied about a hundred subjects, of which only
52 have actually used MDMA. That's not exactly hundreds of people, do you agree? Furthermore, you don't really present yourself as someone with access to scientific journals...but I could be wrong on that one, of course.

If I have stated anything in ignorance or with misinformation please feel free to correct me.
You have highlighted some interesting points of the study, although I do believe they were already highlighted somewhere in the beginnen of this thread (but who bothers reading all posts anyway, LOL). However, although I would definitely
not call your response ignorant, here are a few comments:
In conclusion, MDMA by itself is relatively save but when combined with other substances it becomes dangerous.
The article did not look at the effects of MDMA in combination with other substances, they merely excluded poly-substance abuse. So this 'conclusion' (more specifically, the second part of is) is speculative at its best. Furthermore, calling something 'relatively' safe does not really say anything, because you make it relative. I understand what you mean by this, but it would only be a solid conclusion if they had established conditions under which MDMA is safe. This was not the point of the study, so I don't criticize them for skipping this. But concluding something is 'relatively safe' without proper conditions is not saying anything.

Not only were the previous studies done on MDMA done in a lackluster manner, they were believed to have given proper results. Now we actually have a proper study done.
A lot can be said about this statement. For instance, not all studies the authors regard as 'done in a lackluster way' are identified, so the reader has no means to conclude for him or herself if those studies are indeed faulty. Of course it would be impossible to name
all studies, but they definitely could have mentioned a few large reviews of meta-analysis of which the majority of studies were 'lackluster'. Without doing so, it is an argument that cannot be measured by outsiders; everyone can find at least one or two studies that are carried out in a shitty way, it says nothing about the quality of
their research that other fucked up.
Then, comments about
their method can also be made. For instance, they use a cross-sectional approach with about 100 subjects incorporated. Cross-sectional approach means you can
never look at trends in time or development of cognitive impairment; you test every subject at one point in time and base your conclusions on that. This is less solid than a longitudinal study design, where you follow subjects over time and test their abilities at multiple instances. Here, every subject functions as it's own control over time, which is always better than the use of 'healthy controls', since you can never correct for everything.
Secondly, the number of participants (106 if I recall correctly) is very limited for a cross-sectional design. Usually, cross-sectional studies incorporate whole city blocks. This does not literally mean that you can say nothing when you include only 106 people, but it does raise some questions... If they use a study design that is usually incorporating thousands of participants, how sound can there conclusions really be!? If you let someone with good critical writing skills do their magic, you could easily dismiss the approach with a cross-sectional design as just as 'faulty' as using the wrong control group.

I could easily raise some more questions:
- Lack of a proper negative control (never used MDMA, never went to a rave)
- Very strict exclusion criteria (50 times drunk max, that's not a lot for someone aged 25-30)
- No use of brain imaging techniques
- Only
one measurement, about 4 months after last rave i.e. MDMA-use.
Just to show that this study might perhaps be better than some of the previous work, but questions about is can be raised just as easily as the preceding studies.
