Second hand marijuana smoke can leave traces of THC that can be detected in the urine for the next day or so. However, most drug tests have a "cut off level" that's high enough to NOT give a positive result for very low levels resulting from something like this. In order to get a positive result this way, you'd have to be exposed to very high levels of smoke for a very long duration of time in a very small space--thus, it's not likely.

I hope this helps!
