Last summer I bought/consumed about 40 E pills that were definitely pressed with meth. Id roll for a good 4 hours, but then I would still be high for at least 8, and about half way through my relationship with these pills, I put two and two together. Still, they had a good amount of MDMA in them and I enjoyed the speedier part of the high as well. Though blowing it isn't as crazy as smoking it, I can definitely see how someone could go over the edge on that stuff. I also bought some 'molly' from a friend at a festival, but he hadn't tried any of it. Shit tasted like rock salt and nothing like E. It hit me like a freight train and it had me longboarding as the sun was rising. It was too intense though, and I realized it was speed and I flushed the rest of the bag.
I don't party like that anymore, but I wanted to share how simple it is for a recreational drug user to come in contact with this stuff. Sorry for any typos, im on my DROID.
