I took one hydrocodone pill today (Saturday) for a headache. It was given to me by a friend when I asked if she had anything for a bad headache. I totally forgot I am supposed to take a drug test on Monday to return to work after being on medical leave. Will hydrocodone show up in a drug test within 48 hours? I am not a drug abuser. I just was not thinking and looks like I messed up. Thanks...
