I don't smoke at all but have friends that do and was at their house quite a bit lately. When they smoke i try to keep my distance and dont usually sit near them smoking but can always smell it. The other, saturday, i was sitting htere not paying attention and they went through half a joint before i noticed the smell and moved. i wasn't really paying attention and thought they were just smoking cigarettes. its been 5 days now and i took the test today. i play basketball like everyday since its happened and drank alot of gatorade. not really to flush out but it couldn't have hurt right lol. What are the chances of the test coming back possitive from just being around them smoking like that?
