If it is an Rx medication, you better have a copy of the 'script or the label with you. If you don't, it can be difficult to explain to the LEO that has had legal reason to search you. Ask my wife, she experienced this herself in Dallas.

Luckily, the fine officer went along with a cell phone call to me. I verified the script and offered to come to the scene with it. (pill case fell out of purse in front of officer at traffic stop.) Also blew any chance DW had at hiding the ticket from me......
