That may work to flush the alcohol out of your system. Now if you are talking about substance drugs; which I’m sure you are unfortunately drinking water will not rid your body of drugs. So you may want to think twice about doing any type of drugs before taking a drug test.
I hear vinegar does, but I don't know I don't do drugs and I agree with the first guy, but no water doesn't do much considering that a lot of drugs stick to your fat cells and other cells and water doesn't affect them.
No way! Just get some ones urine b4 u get the test, then make sure u keep it warm, maybe place it under ur armpit, then use it when u r there! Or just buy some hand warmers or toe warmers to keep the urine hot!
Actually of you urinate enough you can rid certain substances as long as they are not substances in which flow through your blood stream. But it's not really about how much water you drink but how much you urinate although drinking immence amounts of water will cause you to frequently urinate
