How does a urine drug screen tell the difference between Oxcycontin and oxcycodone?

Answer 1

Oxycontin is just a time release version of oxycodone. I take oxycodone 15mg, which is fast acting, you can get Oxycontin in 60 or 80mg but it is made to work over a longer time period, some people get into trouble with Oxycontin because they break time release by chewing it, this is very dangerous to put that much oxycodone in your system at once. The only way a test would detect the "difference" is by the amount in your system but not the drug. If you chew up an Oxycontin 60 it will show up the same as if you took 4 oxycodone 15mg. It's the same drug, just different concentrations.
