Will I Pass A Drug Test If I Sat In A Small Room With People Smoking Weed?

I never smoked weed, but I have sat in a small room with people who smoked weed about 4 times in the past 1 month. By sitting in the room and just breathing normally, will I inhale enough smoke that I will not pass a urine drug test that I took Friday??
