When I had my wisdom teeth removed I received a legal prescription for opiates and had the prescription filled and took possession of them. Thankfully I was able to tough it out with just NSAIDS and never took them.
Was I an opiate user? If I just keep the script but never fill it am I more an opiate user than the guy on the street with a little baggy of white powder? People seek out and obtain scripts for stuff they never use, all the time.
