I took a drug test for the P.O. about 4yrs ago and I can't remember what exactly they tested for, but there was either 4 or 6 slots to test the urine. So figure pot, coke, heroine, etc... I think there were 4 slots the more I think about it, but not positive. I would go to the doc and try to get a script or if you still have your old bottle bring it with you. You can even get a print out from the pharmacy saying you were prescribed that medication.
Lortabs is
hydrocodone so at least try for a script for some weak vicodin.
