I'm 29, 270 lbs, and am in fair health. I drink a good amount of water. I tried 30 mg of OxyContin intranasally 68 hours ago and have a piss test to take today. Will it show up? What's the half life? Do standard on-the-cup tests check for oxy? I have a prescription for codiene coughsyrup but haven't taken any. Will that work as an excuse if I do fail?
