Well i think coffee is a diuretic so it makes you piss more. So the idea is to fill your bladder with practicaly water with little drug left in it so coffee would help but i dont know if it would definately pass you without also drinking loads of water and the other ingrediants.
ManaliTwist Reviewed by ManaliTwist on . Coffeee and Urine testing So heres my idea, I noticed that when you drink coffee if goes through your system faster than other liquids. So based on that would it be beneficial to drink coffee before a test since it travels through your system faster than other liquids which would mean it would collect less waste in your body to be tested? OR would it be useful to maybe make concoction of cranberry juice water and coffee to flush your system out, the coffee making it so that you expel more waste at a faster rate? Rating: 5
