Yes, their structures are completely different. They wont even show false positives for each other. Oxycodone's structure was based on morphine while methadone's structure is more like darvocet
No. Absolutely not. They are both oxycodone. Oxycontin is just a longer acting formulation. Yes they can. The tests at my doctors can definitely tell the difference. one will show up has Oxycontin...
