If it is true: That you only had one puff of a marijuana cigarette then that should be sufficient time to drop well below cutoff levels and produce a negative test. If however, you are a regular heavy smoker there is a small possibility that a 16 day abstinence would be insufficient time. Why not consider stopping altogether and you won't have to ask these questions.
