Probably you're ok: The reports I've heard suggest that you will pass. There is a small worry that if you were in a very non-ventilated space w/ it for a long time - some may show, but read this: http://www.homehealthtesting.com/blog/2010/06/does-second-hand-marijuana-smoke-show-up-on-a-drug-test/ I think they will be reassuring to you.

Not likely but: depends on the sensitivity of the hair testing being done. If you are in a room where a large amount of smoke is present, you would have to be inhaling enough for it to have a mood-altering effect in order for it to register in a hair follicle test.
