I know my friend is taking oxicotin and she has a drug test tomorrow. She said that the drug test to be performed is only testing for opiates and since she is perscribed percoset that the test cannot define which opiate is in her system! Is this true? Do they have to give her a different test to find out which opiate she is taking?
