i work in a warehouse and anytime you are in an accident or get hurt you have to take a drug test immediately........so everyone i know there that smokes weed fill an empty bottle of visine with bleach and when they get the drug test they will put a few drops on their finger and let it dry then pee on their finger during the test......some guys say just put 2 drops in your pee and mix it up and you will pass.......i have never done it yet but i have my visine bottle ready just in case, my friends have passed the test so im confident it works.
hope this helps somebody.
