Asking for a friend of mine who is freaking out irrationally. He took 5-30mg of Roxicodone (Instant Release) Oxycodone for about a week daily. He has a drug test for a job Friday, and that will make it 3 weeks since his last use. He knows it was stupid, that's why he's stopped and been clean for nearly 3 weeks. He has been exercising and staying well hydrated. He is 5'10", 145 lbs. with a fast metabolism. What is the maximum possible time oxycodone/oxycontin can be detected even if it is tested through urinalysis? (Even in extreme cases.)
