It's not the smoke that gets into other apartments, just the smell. You may not like the smell but it's not actual smoke. The smoke has dissipated before it can think about reaching another apartment. You would need to be in the smokers' apartment to claim any real ill effects from "secondhand smoke". Makes me wonder why all us baby boomers are still alive, healthy and kicking IF SHS is as deadly as everyone is claiming. Listening to the dogma these days would mean everyone born before 1980 should already be dead or near death, given the shs we were all exposed to from birth. And unlike carbon monoxide - which CAN/WILL kill you - at least you can smell shs and do something about it.
