Like I said a while ago,in another smoking thread, I've switched to making my own cigs. I have a little machine, I buy Natural tobacco and cig tubes. It accomplishes a few things, 1.) I smoke less because I actually have to MAKE a cig, 2.) I don't get all of the added chemicals, including the crap that makes cigs go out, & 3.) It actually smells better. I do smoke in the house, but I'm right by a window fan, used to exhaust the smoke. I only have problems with exhausting the smoke when the wind is out of the South, as it is today.
I did notice that after they added that crap to make the cigs go out, I was coughing a WHOLE LOT more.
