Did the studies specify the dosage, frequency, and duration of use in the long-term users they studied? I would not be surprised if they show that taking MDMA e.g. once a week for months on end caused significant damage, but I would be much more surprised if there were significant long-term deleterious effects from reasonable doses spaced months or years apart.
