I've been exercizing really good for the last 1.5 months but I am still coming up with a faint line. I am not sure, if it is a 15/ng test, that I will come up positive. I am just wondering what the specifics are. I can't find them on google :/

Can a donor test positive through passive inhalation because he was in the same room with someone smoking marijuana?
This is a question that has had a long history. It has been shown that it is possible to have minute detectable levels of THC from passive inhalation, although with the standard DOT/SAMHSA screening cutoff (50 ng/ml) this is not possible. The controversy came from studies that showed that it is possible to produce a positive urine test when an initial cutoff of 20 ng/ml is used. There are numerous scientific articles that validate this point; however, exposure conditions were so unrealistic that they were characterized as nearly intolerable certainly not passive but active participation. Since all certified labs must use the 50 ng/ml for federally covered workers, a positive due to second hand smoke is not possible.
I'm guessing, since it's non federal, it will be lower then?
By doing a Forum Search with the terms "functionally equivalent metabolites", and "selective methodology", you'll discover that even though their cutoffs numerically differ, a 50 ng assay screen is functionally equivalent to the 15 ng GC/MS.Quote:

Edit: Actually, read post#7 of this thread:

Ok I see they just test for that one metabolite then. I will have a sub ready just in case, but if it says 50ng on the sheet i'll risk it. I'm about 27 days clean with exercise so i know i'm on the borderline.
Without a quantitative analysis performed, how do you know this for sure?Quote:
