I've read countless research papers on the elimination period of the inactive metabolites (THCCOOH) in urine. Most of them suggest that even for chronic users, the last positive detection (EMIT Cannabinoid Assay - 50 ng/mL) should be somewhere around 720 hrs ~ 30 days. I smoked 2 grams across three days (last contact being exactly 18 days ago). That might qualify as "a one time chronic use" - not sure what lingo refers to what here.

I have consistently tested positive in about 7 home drug screens (spaced about 2 days apart for the last 15 days) using the 50ng/mL cutt off. I am 5'9", 138lbs, that makes my BMI 20.4. I run about 6 miles a week (2 miles thrice a week) and I eat relatively healthy.

I have to take a drug screen in about 12 days and I need to pass it. Loading up my body on chemicals (naicin and what-nots) is not an option for me, I just simply can't take the risk of intoxicating my liver. Life is too precious, even for employment purposes.

I am being pro-active and asking for any safe ways to ensure that I pass the test. (Am sure it's going to the the EMIT with a 50ng/ML cutoff test).
It's a medical physical, so substitution is out of the question. I could try dilution, not sure how effective that is without the risk of the sample being rejected.
