After viewing alot of posts in the forum i realized that substitution is probably my best chance of me passing this test i have on either Friday or Monday. I don't know too many people that would give me some of their piss to use so it looks like i'll have to use the synthetic urine. soooo.... I live in the Martinez/Pleasant Hill/Concord/Walnut Creek Does anyone know of any smoke shops in these areas sale synthetic urine? any type of brand i should pay particular interest to, when i make my selection?
