Sure, if the test is sensitive enough, it will pick up your exposure. Your total dosage depends on how much the person was smoking, the concentration of the THC in the air, the ventilation efficiency of the room, your exposure time, your activity level...there is no easy way to know for sure.
Clarification needed: if you are in the same room with others who are smoking it?
No, not unless your in a car maybe and they're directly blowing in your face, otherwise I highly doubt it.

Yes, smelling marijuana means you have internalized a small portion.
Marijuana
The same as weed, which it's made from.
No! You do not get high off peoples weed when there in the same room as you. People always think that.
That shouldn't have anything to do with their reproductive system.
no, however smoke inhalation is not natural and does cause a minor displacement of oxygen
Yes of course it does. It will remain in your body just as long as illegal weed would. Weed is weed. no its doesnt stay in your system at all. it has no THC
Smoking resin is the same as smoking weed, so the same amount of time. About 30 days to be safe
Answer removed due to being offensive, I'm sure you'll find another answer soon enough. (:
yes. you can get high second hand, which means its in your system
From what you have stated that weed was probally out of your system within a week of it being consumed. You are fine and will pass
Weed is stored in fat cells in the body, therefore the more fat cells, the longer it will take to flush it from your system. That being said, appox. a month. It can be done more quickly by increasing fluid intake.
