Great question ! Couple of points: If the job is in the same state as you went to college, then they shouldn't be able to reject you because of a positive test for marijuana. They might be more concerned about other drugs. Unless you were a heavy user, you might be below detectable levels already. My suggestion: Chill man! Delay taking the test if you can, but not too much. Take the test. If you pass the test - then you were worried about nothing. If you don't pass the test, then you have a nice easy chat with the manager you had the good interview with. At that time explain as you did here, it was for a reason and you have gone off it. Offer to do another test at the end of your probation period to confirm that you've kept your promise.
