Cory Dear answered question 3/13/2011 Is There A Harmful Drug Interaction If Suboxone Is Mixed With Ecstasy(MDMA)? Joe,uh no, have you not heard of mixing suboxone and xanax is deadly, look it up. The guy that posted first on this page hopefully he is alright. They have just recently found this out so his doc probably didnt know 3 years ago, but I hope he is ok
