i have a urine drug test for pre-employment. My questions is: I had only one puff before 58 days. I also bought Qcarbo Clear with five Vitamins B2 Pills (comes with it). I drank some water in the morning, AND later 20 Oz before 1 hr...then wait 20 min and drank QCarbo with Pills and after 15 min another 20 Oz. water. I waited for 2 hrs and went to drug urine test. I pissed twice before I went for test. Am I going to Pass it? I also found out that they have Detector for those who use cleasing product for temp. flushing their body? Is it true? Guys, I am really worried. Please help. Your reply will be really appreciated. Thank you in advance.
