Creatine and THC (or the metabolite, don't know the word). I am (counting today and the first half of Monday) two days till my UA. I have just failed a home test about 30 minutes ago and was thinking about pounding a bunch of cranberry juice, creatine, and some multi-vits. Gonna take some Niacin too, don't know if it really works or not but might as well try it. Wont go overboard, just enough to get a good flush any way. It's been 14 days TODAY since I smoked last, and I have not smoked in about 6 months prior (not sure really when but it was a while). Last time I smoked I had to take a UA and passed in like 5 days. Dunno whats different this time but it sucks.
My question.... What do they look for in a drug test? What is in URine that makes it "authentic" or not dilute?
