Question
Hi
I am not allowed to smoke pot or drink alcohol.  i was recently at a club where someone lit up a joint.  I may get tested this week.  My testing could be at any time.  Will there be traces of pot in my system?

Answer
There are two tests that I know of to detect marijuana, a urine test which shows drug use within 48 hours and hair samples which show drug use up to 30 days, depending on how long it has been since your last hair cut. I can't really say whether second hand smoke would show up unless you stood next to the person for sometime. A minute or two exposure should not turn up in a test.
