Mdma?

A friend of swim's gave her a bag of what she thought was meth. It looked like crystals so she thought it was. Well very weird stuff started to happen as swim gave it a go. Swim usually smokes her ice, but very weird effects was happening and it left a thick dark residue unlike ice. So she thought ok rail it. It effected her somewhat but the duration was a couple of hours? Also the rails were not pleasant to say the least. Ice is a lot longer. So she railed more and more. Well stupid swim started to feel extremely hot like feverish. Never happened on ice. Also later on just felt sick and nausiated. What do any swiys make of this? Also same dude sold "ice" to a friend and when she smoked it, it started popping like jiffy pop popcorn? The residue left was grey with pink balls? What on earth was that?
