In drug testing, the amount of a substance found in your blood in measured as nanograms per decaliter, if I am not mistaken. I recently turned in a test which measured a level of opiates above 10,000 n/d. I have rx for 30 mg. MSIR every 6 hours, as needed. Would a level above 10,000 be consistant with use according DR. orders as stated above? What about if SWIM dosed say 1-2 hours before he dropped?
