The timetable for detecting norco in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time Norco will show up on a drug test.

Other factors that can influence how long Norco remains in the body are the frequency the medication is taken and the amount that is used.
