i failed a urine test said i had taken cocaine , started an argument with tester my argument was that i was 42 ,married with three kids 17 stone and way to boring to do any drugs . any way he asked what painkillers i had taken turned out that it was codeine . still never got job apparantly its not the done thing to threaten to make testers drink samples .crap job anyway . by the way if you tell them about codeine when they test you , you get suspended on pay while it goes away so long as thats all you have on you
