And Sec (Moderator) says....

I would guess that within a year or two, this will actually materialize.

Another tidbit:

As of August 25, 2008 it will become mandatory all DOT return-to-duty and follow-up drug tests be observed. Not monitored, not 'supervised', but observed. Currently, it is left up to the employer whether these tests are observed. So if you fail a DOT test for any reason from now on out, expect observed tests if you ever want to have hope of getting your job back.
I just think it's all interesting and the thread is about dead. I hope we never see the day products like QF become illeagel...
jeffman Reviewed by jeffman on . old urine I recieved urine from my friend roughly 48 hours ago (maybe a little bit more). I stupidly did not refrigerate it. I just now took the pre-employment drug test with it at Quest Diagnostic. They said my pee was in the range of temperature so that was not a problem, but can they tell its old pee??? I'm FREAKING out. I'm such an idiot but I'm new to smoking and didn't even really think about it :( Rating: 5
