Well to a certain extent, although you've been wrong on everything else, you ARE in fact correct to seperate "generic E" from MDMA, as they most certainly are not the same thing, even though E is in fact meant to have MDMA (as far as im aware) as its ONLY active ingredient from a mind altering perspecitve, the reality of course is that as most E is in fact controlled by criminal gangs only interested in profit, the actual ingredients can vary massively.
