You would need to be a phone booth (remember those?) with a consistency thick enough to not allow light, and be in that for several minutes..... Merely being around tokers is not going to show up.
Can You Test Positive For Thc From Second Hand Smoke?
I had a friend who did not smoke at all but her friends did and when she got tested at her job she tested positive . It was a low level but positive just the same.
