Maybe not the best idea. While the report clearly shows the irreversible damage caused by MDMA (as do many other reports), it does conclude with "Contrary to results of other neuroimaging observations, Mr. A’s brain scan did not show any gross cerebral abnormalities, especially at the hippocampal level," and over eager students might take away the wrong lesson.
Not sure... I think it's too extreme a case to show, most students would rationalize that by thinking 'but I'm only taking one it's not like I'm taking 40 000 pills'
That doesn't mean that a pill here or there will have the same effect. Considering how many different drugs he was on, we don't know that it was even the MDMA.
Let's keep in mind that this was five times the previous known lifetime dosage of anyone else.
