It will show up as an opiate on a 5 panel drug screen.
They will show as separate items
It will show up as an opiate but after further testing they will find out that it is morphine
Yes. Some places (like the methadone clinic I went to) had a way to tell between Oxy and morphine. But on a 5 panel drug screen, yes, it will show up as morphine.
