I am not sure if it will help or not. I just went for pre-employment testing and they only had me do a urine test. They make you take off all of your coats and empty your pockets and they send you into a bathroom that has everything taped off. So you cannot dilute your sample or ruin it. It is illegal for them to watch you if it is for pre-employment testing. I would recommend buying the home tests and experiement with different methods of water, juice and niacin to figure out which is the best option for you. Saliva is rarely used but, every job is different.

Good luck. I hopefully will be passing the test. I should find out on Monday. Until then lay off the MJ.

As one of my teachers says

The soultion to polluition is dilution.
