They changed it before then. If the quantitation in the urine is less than 2,000 ng/ml then poppy seeds are a likely explanation. The DOT and all federal testing uses a 2000 ng/mL cutoff for this reason. Although the possibility is unlikely, there have been cases of poppy seeds causing positives as high as 5000 ng/ml. If the quantity is greater than 2000 ng/ml, then another test, 6 monoacetlymorphine (6 MAM), is automatically performed on federal workplace samples. Monoacetylmorphine is an opiate specific metabolite and is proof of use. If anyone has more up to date info please correct me.
