How does a scent occupy space? Example: in cigarette smoke, is the smell of the smoke bound up in the smoke itself? Can you only smell it as long as you are in proximity to some trace of the smoke?

When you smell something, you are having little bits of whatever you are smelling go into your nose, where they hit receptors for various chemicals, which gives you the sensations of different smell. So, it is the smoke itself you are smelling.
