Possible for the smell of someone who has just smoked marijuana/crack (but not currently) to affect the brain?

Is it possible for the smell of someone who has just smoked marijuana or crack (but is not currently doing so) to affect the brain of someone else in a house, even if never exposed to the actual smoke?
Part of the problem is that I couldn’t even smell it strongly enough to tell if it was either or in fact a drug of any kind.
Actually, I have OCD – i’ve never touched said drugs before in my life. I’m just worried about second-hand exposure.

I think this is a pure psychosomatic response. If you were never exposed to the smoke then I SERIOUSLY doubt you could get high off the smell. That’s like saying you can get a high when you pump gas into your car because there are kids who huff gasoline–just doesn’t work that way.
