I usually smoke more, that way the old smoke is replaced with the new smoke. Eventually my eyes get chinky enough to the point that I just can't see the smoke, and for the smell, I love it so I bask in it once I am blind
No but really, I have virtually no worries when it comes to smell so I usually just have a fan blowing out of the window if I want the room cleared, usually clears up in a bit so if you are rushing then I don't know.
And if you are worried about neighbors smelling or something, again I don't know, sorry. Time to go smoke more.
