There's soo many ways to pass a drug test. I had to get one for a reason that shan't be disclosed, and before leaving my house, I took my necklace that can hold liquids (its a blown-glass necklace meant to hold this liquid stuff that glowed, but I needed it for a different purpose), I took the pendant off, filled it with bleach, closed it, taped pendant around my richard (it held like 10 drops of bleach tops) and before pissing in the cup, added bleach. Boom, passed.
