My mother has been on oxycontin 8 years and she had some of her medication stolen so she has none and her friend is offering her a pill it is the same mg as she takes it is 80 mg but the pill her friend is trying to give her does not look like oxycontin 2 me? It has a marble look to it it is green with like back specks in it ? WORRIED!!! She is going 2 start withdraing soon and I am afraid she will just take it unless I can tell her what it is 4 sure I do not think it is oxycontin but I do know it is something strongbecause I've seen the woman who takes them and she is one hot mess on them! I would appreciate any help this is my mom and I am seriously worried!
