Drug test/detoxing

I know this has been spoken about many times before on the OG, but I am wondering what is the best supplement/headshop cleanser out there to flush your system out. 

And yes I know the best way to pass a test is not to smoke marijuana. 

that's not gonna work. the only surefire way (other than not smoking) is to substitute a synthetic urine or clean piss. I have done this recently and it was super easy.

you just need to practice getting the temperature right, which is easy. i used the bottle that came with quickfix because it has a thermometer on it, but i used real clean urine in it.

Have a friend pee clean for you. Free and reliable.

If your job depends on it, don't trust a detox drink.
