Causing you to fail a drug test?
7 Dec 2012
Norco contains a combination of acetaminophen and hydrocodone.
It is the hydrocodone component that is of interest when urine drug testing.
Many factors influence how long a drug remains in your system. Body metabolism, physical condition, state of hydration, age, frequency and method of usage will all affect your result.
The rate at which a drug is eliminated from your system is related to its half life.
Hydrocodone has a half life of around 4 hours and acetaminophen has a half life of around 2 to 3 hours. It usually takes about 5 to 6 half lives for a drug to be eliminated from your system.
With that in mind, and other factors as outlined above, for urine testing purposes you should allow around around 2 to 4 days to get hydrocodone out of your system and 1 to 2 days for the acetaminophen.
If you know you are going to have a drug test the best thing you can do is stop taking the drug.
