How long do Xanax stay in your system

3-7 or 7-10 days
It will take you 3-7 days to get xanax out of the body system for single users and relatively longer for regular users, say about 30 days.It will take about 7-10 days (for single use) or about 30 days for regular users to have xanax out of their system through urine.
A significant amount of Xanax (alprazolam) will be in your urine very quickly as you take it, just shortly after it's absorbed. I would guess that if its been less than 10 minutes since you took it, there's no way you would have enough in your urine to fail a drug test. My best guess would be 1-2 hours after taking the xanax depending on dosage, but I wouldn't try it. Alprazolam can stay in your system a while. If you take it once, I would probably expect a about a week to be clean, depending on dose and test cut off level.
