Second hand smoke

Hey,
I was visiting some friends for about a week, and they smoked quite a bit (~2/3 times a day). When they did smoke I usually chilled on the porch or in the kitchen (The kitchen is right next to where they smoke and its essentially a big room). I made sure the windows were open but I could still smell it.
Is it possible to fail a drug test?

You'll be fine. You wont test positive on the basis of secondhand smoke.

i get tested multiple times a week, and i hang around my friends who smoke pot all day. ive even accidentally eaten a tiny piece of weed when i rolled them a j. youll be fine
