I just found out. His room has always had a very strong odor, and now I know what it is. Suppose we shared an actual room - which we don't, but it seems I inhale that smell for hours each day, so it's almost as if we do - what's the likelihood that I'll fail the drug test? I have abt 4 months b4 I have to take it. I totally ignored this discussion in the 24 hour course because it didnt seem likely to be a problem for me, and google doesnt provide a clear answer.
