How Long For Clean Urine?

NOTE: This is a guide only and cannot be guaranteed to be accurate in all cases. The information, though taken from NUAA’s publication “User’s News”, originally came from a pharmaceutical manufacturer (ADIS), so it should be fairly reliable! Different people will get different results because of their different metabolic rates. Do not assume that the shortest time frame given will give you a clean test, it may take more or less time, also, all sorts of substances can interfere with the test, the most obvious being bread with poppyseed!!
