A member asked:

How far back does an oral drug test detect cannabis?

A doctor has provided 1 answer

Depends: Since thc (the active ingredient in marijuana) binds to fat, it depends on you much fat you have, how much you use, & how physically active you are. It would not be unusual to test positive for a month.
