do pain killers show up on piss tests

[thepr0digals0n]

i am probably going to take vicodin and oxycontin in the near future and i was curious as to how long these pain killers stay in your system, because i have urine analysis in the near future. is this a no go, or can i do this and get away scott free?

that would be a no go.give yourself a week after you take them.
