have you not read any other threads on here about detox drinks? those detox drinks do not work. IF they work, it is because you also have to drink a bunch of water after you take them, and its the water that is passing the test, the drink doesn't have anything to do with it. my mom used to do drug testing for a living and said those things are just a way for someone to make some money. the only sure fire way is not smokingm dilution or substitution.
