1. Eat lots of red meat the day before and day of the test.
2. Drink tons of water from the moment you wake up.
3. 1 1/2 hours before the test, drink a bottle of QCARBO. This step is very important because it will offset the dilution and give your urine a natural color.
4. Don't go to the test until you start to pee yelow again.
5. Use only the mid stream of you piss. Let the first and last go into the toilet.

Do a test run at home and good luck.
Capt Cannabis Reviewed by Capt Cannabis on . Plan C-Using Substitute but worried about temp Can anyone help, I have to take a pre employment urine test and have been a regular smoker for 10 yeasrs, daily. I have not smoked now in 2 weeks and two days. I first went and bought a 7 day detox cleanser from GNC that the guy swore would work. Well I went and bought a home drug test and failed it. Freaked, then moved on to plan B which was to go to a head shop and buy Omni cleansing soft gel and followed the instructions like they advised, drank lots of water and went to take the test.
