How long does Subutex remain in the body?
it takes a WHILE
First, it takes most of a day to get in !
then up to 5 days to get out!
so.. a week would be long, 4 days would be short... about 5 to 6 days.
On the other hand, some labs have really lousy testing (some have a very very high amount of drug that they take as a positive and then that drops the timing by a day or two). This supposes that someone has normal kidneys. If they have half the normal kidney function the timing might double (10 to 12 days). and that we are talking about 8 mg, usual way of taking it, usual person, and NOT a hair test.
