Cannabis: Depends on what is being measured and the pattern of use..Thc remains in the urine a much shorter time that its metabolite. For one time exposure this may be a few days for more frequent users up to 30 days and rarely longer.

One month: Due to thc half life, it can be up to one month... If it did, that also likely means that the tested person was a heavy abuser....
