It depends on how long ago it was smoked.
If it's more than a week ago, you should be ok for a urine test.
Marijuana does store in your fat cells though, so maybe other kinds of tests could find it.

Would you fail a hair test if you smoked pot one time and only took 3 drags 2 months ago?
No. Not unless you shaved yourself bald. Seriously. Once a chemical is locked into the keratin in your hair, it's there forever. Or at least until it's cut off. If a hair on your body can be found, that was growing there when you smoked marijuana, the hair drug test can detect marijuana use from it.
Does marijuana smoke stay in your hair forever?
No, exposure to the smoke of marijuana does not stay in the hair forever, but duration does depend on the frequency and severity of exposure and frequency of washing hair. What does happen though is, if a person smokes marijuana there are traces of it that reaches the follicles and grows into the hair. A hair sample can be taken from the person and tested and can prove that he/she smoked marijuana.
