I could also use the substitution method using my roommates urine. My main concern about this is the possibility of their being a two way mirror in the testing room. Why this is obviously a huge violation of privacy, I do not want to rule out the possibility that it could occur. My roommate recently took a pre-employment test at a different facility in town and there was a mirror set in the wall that he thought was suspicious. Although it was a different facility, I want to be as prepared as possible for the test. I couldn't find much on forums about two way mirrors so has anyone ever heard of that?
The use of mirrors or cameras are not allowed. If there is a situation where an observed collection is taking place, there must be a live observer (who must also be the same gender as the donor). Read post #4 of this thread:

So what do you think Burnt Toast? Are the synthetics, such as the well known QF, going to pass not only the UA for cannibanoid metabolites, but any tests administered for authenticity?
As long as the QF batch is unexpired and had been kept away from direct sunlight, it will pass the validity checks mandated by DOT.
