I had foot surgery August 17th I had been taking vicodin for pain up until September 5th, I need to take a pre-employment drug test on the 12th will this still be in my urine?

It is usually able to be detected in urine for about 72 hours, but it may stay in your system longer since you obviously took it more than once. If you have a prescription for it, it shouldn't be a problem. :)

If you have a valid prescription, a copy should be given to the testing lab. That way you will be covered.
