Exit, I know what you are saying, you are right I shouldnt have too, and I probably dont, but I figure it is just one less reason to not hire a guy, you know?
Actually, no! That is DISCRIMINATION AGAINST PEOPLE WITH DISABILITIES!!!
I am not kidding, or exaggerating. Employers are legally bound to disinclude your taking of legally prescribed medications unless it directly impacts your ability to safely or legally perform the job they are considering you for.
That may sound like a loophole that they could use, and they might if it is really borderline, but frankly, a positive opiate test doesn't mean much. Anybody with half a brain should know that it is quite possible to test positive for opiates and be not in the least impaired to do most types of work, or even drive!
