I am amazed at some of the answers I've read here. 1st of all if you are giving an answer based on what you've read on the internet then realize that while the net has tons of great info, it is completely open and therefore it's content and "answers" should be taken as lightly as helium. This is what I can tell you from personal experience: A: To the severity that they test is situational dependent. B: Question, how long can a drug test pick up on Benzos?????  If you took a .5 3 nights ago then the test will pick it up but it will probably be within "acceptable levels". On the other hand, and this is just a little tongue wetter here, but alcohol (ie beer consumption) can be detected in a urinalysis for up to 5 to 7 days now.  That's not the police sobriety breathalyser test but a 7 panel test. What that means for benzo takers is that it will be detected in your system for a LONG while (think +-30 days)  if they test for it.... and more and more places are testing for it these days.  So if you are prescribed a benzo then of course, no problem..... unless your job requires you to do things that would put you and your coworkers in compromising positions due to your medication use.... ie forklift driver... etc... If you do not, however, have a prescription for xanax or valium or kpins or whatever kind of benzo you might have "accidentaly" taken 7 of a few days ago you may very well be screwed.  Then again you may be lucky but either way you won't know until they either do or don't call you to tell you you passed or failed.  Lucky if you do.... expect not to if you've taken more than .5mgs in the last couple of days... Truth sucks sometimes
