Ugh.. I know how you feel. My dad was a terrible chain
smoker.. he closed the door to his room, but the smoke would waft
into our rooms, and we kids would all wake up in the middle of the
night everyday breathless and coughing because the smoke was so
thick. One of my siblings developed a shortness of breath, but that
wasn't enough to convince him to stop. Just like your bro, he never
listened to us and often scolded us for broaching the topic.
He's passed away prematurely, because of heart problems perpetuated
by his smoking habit.
Sometimes people block their ears out to whatever they don't want
to hear... unfortunately this is a personal decision your bro has
to make. If your bro doesn't listen to family, maybe he'll listen
to friends. If you know a friend of his, maybe you can seek help
discreetly.
In the meantime, I find that [b]apples, vinegar and lots of fresh
air do a mighty good job of removing smoke odor from a
room - that is, until the smoke starts coming again.[/b]
thanks a lot for your suggestions. 
usu when the smoke gets too bad, i either spray a lot of perfume in
the room or i will open every possible window and opening in the
house to circulate while i escape from the house.
