How long does it take for norco not to show in a urine sample?

Because norco is the same as hydrocodone, it should only be detectable for 3 days (72 hours) depending on how long you have been taking the drug. As with marijuana, it may take longer to get out of the body such as 5 days at longest depending on usage.

Depending on the sensitivity of particular test used, it could be detected for up to thirty days. A positive reading could prompt a hair test (for law enforcement) which will yield results for as long as six months.
