How's airport security about finding non-prescription Xanax or whatever when you're flying?  Do they ignore it, confiscate it, or call the cops?  I've had Tylenol bottles looked over pretty closely crossing borders and was told to make sure any prescription meds were in a bottle with my name on it. I can just see someone looking up at the airport drug dog and telling the officer that the Dilaudid in the baggie from your friend was for flying anxiety.
