I took mdma and my resting heart beat is 108 beats per minute, is that normal or should i get the the hospital?

A bit late: I expect you've either returned to normal or went to an ER - but in any case - this is a definite sign that you should NOT use it again. It's a risky drug and for the pro(s) there are bigger con(s). Have fun, but be safe.

Advice: Contact a doctor, as your resting heart rate is too fast, but am more concerned about your ingesting a potentially harmful agent. I would suggest changing your path ASAP, and counseling with rehabilitation could vastly improve your future.
