conjunctiva. A thin transparent mucous membrane lining the posterior surface of the eyelids from the eyelid margin and reflected forward onto the anterior part of the eyeball where it merges with the corneal epithelium at the limbus.
Its my understanding that Suboxone stays is in your system for at least 72 hours and has trace metabolites that can be detected in urine for up to 10 days (depending on strength and how long one has been on it).
Added 5 Mar 2011: Ok, I learned that the half-life of Suboxone is 36 hours, according to the Suboxone counselor I spoke to today. That is for one dose. This individual couldn't say how to calculate how long the stuff clears out of your system if you are taking a sub-clinical dose.
