Is morphine an opiate? Will morphine show up in a urine test if I took a 15 mg tablet yesterday at 10:00am & go do a urine test tomorrow am? Howlong before it's out of my system?

Morphine is a powerful opiate.

I think it should have passed through your system by that point. You should get a doctor's note explaining why you were prescribed morphine just in case they do find it. It isn't illegal or detrimental if it is prescribed. Most often.
