How long does xanax stay in your system, and is it detectable on urine tests? what about saliva tests?

7-10 days from a single use, and up to 30 days from regular usage. Yes it's detectable in urine and hair, but it's not always tested for.

How about if i was taking them for 5 days in a row and then stopped? then how long will my use of xanax show up in a urine screen?

I found this for you:

"The length of time any drug stays in your system will vary. In large part, it depends on your physiological makeup (e.g., your physical height, weight, your amount of body fat, your age, current state of health, whether or not you exercise mildly-aggressively-or at all). Whether or not you are undergoing any degree of stress (i.e., your "state of mind") at the time you ingest drugs can play a part as well.Still other considerations include your "frequency" of use (1x per day? 3-5x per day?), the "quantity" of drug you used each time, and the "length of time" (days? weeks? months?) of your consistent drug-use prior to your drug test. Even the quality ("potency") of the drug you ingest determines "how long" the drug is detectable in your system when your urine is analyzed (tested) at the lab."
However, for most people, detectable levels (i.e., shows up as a "positive" in a laboratory drug test) of the following drugs stay in the body for these approximate periods of time:

Benzodiazepines (e.g., Ativan, Halcion, Librium, Rohypnol, Valium; Roofies, Tranks, Xanax), 2-3 days

That was an awesome answer to the question about how long drugs stay in your system. Thank you for taking the time to find that information, that was nice of you. Thanks again.
