Army is supposed to be 'zero tolerance' and i know that when i return back to duty after christmas leave i get a urinalysis as soon as i get back but i did read a story that was interesting. Apparently a small group of soldiers learned they were going to iraq and smoked some weed right before so they failed the drug test but instead of kicking them out like they were hoing the army shipped them off anyway and will decide how to deal with them when they return
