what kind of test is it? it would be important to find that out. it its a urine test it could show a postive result for marijuana anywhere from 3-30 days. less if you dont smoke that much for you ild be safe to say that you wouldnt get caught even after a week from smoking dope. but if its a different kind of test i wouldnt be so sure find out what kind of test it is and look up the duration after smoking that the the test would show a positve result.
