The person administering the test is doing a visual inspection of the urine for the color. Alot of cheaper tests (dip sticks) won't test for anything other than drugs.
The energy drink will cause your body to believe that you have over dosed on b vitamins and it will send a ton of shit with your piss in reaction to the overload from the energy drink. I have never failed a piss test or had it come back "diluted" using this method.
Also, diluted isn't an automatic fail anyway, so if you're in a pinch you can just dilute your piss on the fly by drinking tons of water then go back and retest if they make you. Tons of people who stay active and hydrated will have clear piss anyway and companies that conduct these tests do not count a diluted test as a fail.
Not over night? I can't really understand where that statement is coming from considering "over night" isn't anywhere in my post you quoted but you can do it in under an hour and it will still work...
OK?
My point was that you could smoke consistently for every day of your life, including 5 minutes before the test, and still pass.
A piss test for pot is fucking crazy easy to pass. you guys are making this too damned complicated. If you simply drink a ton of water you will pass. It really is that simple.
