Just to answer your other question: If for some reason that subbing is not an option, then your only other option would be dilution....and prayer.
Thanks again. It wasn't my first urination of the day, it was actually just a few hours ago. I'm hoping that two weeks has been enough time for my system to be clean considering the small amount I smoked and the length of time I had been clean before then...but I'll definitely be diluting just in case.
