I know that MDMA is a pure form, and Ex is usually cut with something. My question is, what are the differences in one's experience? I only tried Ex once (only half a pill) and I never want to try it again. I had the worst trip and the come down was unbearable. It made me feel like utter shit. But I have a friend who is scoring some pure MDMA and I am honestly a little interested in trying it... but I don't want to feel all shitty and sketched out the next day. Can someone shed some light on MDMA for me? Whats your experience like? Do you crash hard after?
