will water help speed up excretion in urine during the week before the test, not for weed, but like coke, X, pills etc. As in will it help clear toxins out of your body faster? Seems like it would, haven't found an answer anywhere on google, just that it won't work for thc, except for dilution of course.
I will try the zinc method though, first time I heard of it. Any other vitamins that will actually detox your body? Vitamin-C maybe? Great post, though most of this is common knowledge to anyone who has google'd in times of urine test distress/panic.
