If these are the levels six to eight hours after ingesting, how much (approximately) would have been originally been ingested (40 mg, 80 mg, 240 mg etc)? Also,how would the
other drugs interact with methodone at this level
and the original level (approx). To my untrained eye, these levels look relativley small. Also, is there a way to tell (by examination or labs done by a physician) of someone is a recreational user of any of the above drugs vs addiction or long time user?
