I Have A Friend Who Is A Narcotic User. She

I have a friend who is a narcotic user. She told me she was getting "clean", so I decided to restart our friendship. She was in my car today and when she got out she left behind a red and blue cap that says APO on the red and 30 on the blue, I would like to tell her parents what I found, but I want to be sure what it is. I know she uses Ritalin, morphine, oxycodone and hydro morphone. ...I don't want her to kill herself. My husband is a police officer and he is willing to help me get her into treatment with her parents help. Can you tell me what kind of pill she left behind?
