I wish I could help, I take xxanax for anxiety as needed, .25 mg. ....only .50 mg, that is also a small dose, what kind of test could you possibly be worried about showing that? I am just curious, because since when is xxanx alone something bad? If it is not presribed to you, simply tell them in advance you might find xxanax in my system, because you took one that a friend had after you had an anxiety attack last night....that you just found out that is what you have been having lately & you actually need to go to the doctor to get your own prescription for if & when you need them.
