How long oxycontin stays in your system? - how long does oxycontin stay in your system if snorted

My husband has been inhaled OxyContin for nearly a year and learned a month ago. The only way I will stay with him if he is clean. I tried drugs in urine at home. I bought the examination of oxygen, not only for opiates. He says he had with Oxy for 2 weeks, but I tried it and it was negative. Who knows how much oxygen can remain on your system if you snort?
