I broke my L4 and L5 in January 2010. I had a surgery immediately after the surgery in which they placed metal rods and screws and a bag of cadavar bones in place of the break. 2 and a half weeks ago I had another surgery where they took out the rods and screws. Everything went great and the surgery was a success. Now I'm feeling more like my normal self and was wondering if I took MDMA this weekend, it would have a horrible effect on my back. I'd like to know exactly how MDMA would cycle down to my spine and how it may effect my previous injury. Note: I consumed a small amount last weekend, and did not feel abnormal pain. However, this weekend I'd like to take a larger dose. As I recall after my first surgery, many weeks after, I consumed MDMA and felt better than ever. Is there future damage?
