Hey so im wondering since xanax isn't water soluble & somewhat fat soluble am i right to think that it can build up in fat tissue & then cause a postitve during a drug test even after you've been clean for a while during weight loss? I'm scheduled to go to army in a few months & I already got postponed a couple times because of a positive drug test (thc). Last time i had quit weed a couple months before army but still had a positive result because (as i figured out later) thc is stored in fat for possibly months & then excreted during weight loss. So now I'm wondering can the same thing happen with xanax & is my only safe bet to just quit asap. I take 2-4mg irregularly (once a week - a few days in a row). I don't want to quit but i also would want to get army done so i can go on with my life since i live in a country with mandatory service.
