How fast does cranberry juice clean out your system?

Cranberry juice will NOT clean your system. It is a diuretic, which means it makes you pee a lot. If you are asking this question because of an upcoming drug test, the only way cranberry juice will help you pass is because of it's diuretic properties. Basically, if you drink water to try and beat a test, and it works, it will only work because you're literally just peeing water, and not drug molecules.
