There is no such dose as 1000 mg of Norco. Hydrocodone is the active ingredient in Norco.
Hydrocodone metabolizes into hydromorphone not morphine.
If the test was taken two weeks after the dose it would not show up on the test at all though unless you were using a large dosage.
Norco, 1000? What's that? Never heard of Norco 1000??? Please explain more.
But I can tell you in general, that if you take Norco OR Vicodin, OR Lortab, it will show up as an opioid/opiate. That's what Norco is, or hydrocodone, in general is.
