If someone has took 2 xanax over a period of two days, about how long would it take to get out of their blood and urine? Would the xanax be out of their blood and urine if this was took over a week in a half ago?

If it was taken over a week and a half ago, yes it would be out of the system.

Let me remind you that Xanax is a very addictive and dangerous drug. It should NEVER be taken without a proper prescription.
