A lab is saying that my husband is showing a .48 nicotine level, meaning he is a smoker--he is not a smoker-he is 54 years old and has not smoked since he was 21 years old. Looking for answers and help? Lab refuses to retest or redraw urine saying that now that they have informed us of this that he can quit smoking and now show he is a non smoker. Getting no help from anyone..
