vicodin is a morphine derivitive, and the ammount you took is small, those 500mg caps are mostly acetaminophen.
i wouldnt be worried, but if you test pos for morphene, just simply tell them about the perscription and back pain.
also, it ca make a hugh difference,....was it the first pee of the day (very bad, much higher concentration of toxins),...or where you hydrated and flowing, and was it clear to light yellow. ( if not, my guess if you might test pos)
ps: i work for a drug testing company
