How long does vicodin stay in your system? I took two for back pain before I realized that I had a drug test coming up after being accepted for a job. I have a prescription for this medication. I weigh about 165 lbs with average body fat.

When you have a prescription (current) all you have to do is tell them that you have the prescription and show them the bottle. They are looking for drugs that are not prescribed.
You have to be up front and show them you were prescribed them before they do the test.
