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.
jagerclown Reviewed by jagerclown on . Need Advice on a Drug Test. Please Help Just found out a few hours ago that due to a new company policy, I have a drug test tomorrow morning, and it will be observed. Here is my situation...I smoked 2 bowls on Dec 18, one bowl on Christmas Eve, and haven't smoked since. Before Dec 18, I had been clean for over 4 months (since late July). The test will be DOT standards. What are my chances of passing, and what can I do tonight and in the morning to improve my chances? Any advice will be greatly appreciated, and thanks in advance.
