Either fake piss or get a carbo flush drink. They really do work if you follow the instructions. I beat 6 DOT drug tests in 5 years with the drinks.
Just drink enough water till your piss is clear. You'll pass I promise.
Actually if the dude dosent smoke that much if would benefit him to piss clear because that means there not much shit in your piss. Your basically pissing straight water. If you piss yellow thats all the shit thats in your system I.E. When you wake up inthe morning and take a leak it usually very yellow because your piss has been absorbing it while you were asleep.just because your piss is clear doesnt mean thc isnt in it. Piss being clear jus means you are very hydrated and been drinking lots of water...you want your pee yellow...as far as fake piss. It will work if you get the expensive kind with the chemical warmer...they check the temperature of your pee when they drug test you and if it isnt warm you fail.
Seriously! All those vitamins and shit are just bogus myths. Fake piss is the way to go, but honestly you were doing the right thing from the get go by not smoking, sorry to say but green tea and water will only empty out your bladder. THC is fat soluble so drinking tons of water days before hand isn't getting the THC out of your fat cells but just what you have metabolized into your bladder. If you can't get fake piss or someone to piss for you then yeah by all means try and dilute it with water and what not. But it will just probably come up dilute. If you can get the test delayed by a week or two then start eating a shit ton of food and working out like never before. Its a proven fact that athletes will get clean faster due to the faster metabolism. But don't be working out the day before the test or anything, that will just get more thc from your fat into your bladder for the test you'll actually be taking.you knew you had a piss test in 2 days and stopped smoking for a month or so just so you could pass the test then u smoke 2 days b4 it anyway?
totally forgot to mention the detox drink, i've had them work and not work. and it totally does look like mountain dew!!Actually if the dude dosent smoke that much if would benefit him to piss clear because that means there not much shit in your piss. Your basically pissing straight water. If you piss yellow thats all the shit thats in your system I.E. When you wake up inthe morning and take a leak it usually very yellow because your piss has been absorbing it while you were asleep.
Anyways if your that worried about it go to a head shop and purchase one of those "detoxs" its not actually a detox it binds t the THC and masks it. WARNING: your piss will be an odd color like mountain dew
EDIT: when say shit in piss i mean like all the waste not literly shit
