Dude my parents chain smoked every day in a poorly ventilated mobile home. It was everywhere and we became noseblind unless it was directly wafting in our face (yuck). When I moved out everything was so much better. I was so happy to be able to breathe and not stink, however, I also left the house addicted to nicotine despite never having smoked myself.

I'm strongly suspicious that some of my current health problems might be tied to second hand smoke.

Edit: one thing I did to get around it was wash my clothes so that I'd have an outfit in the dryer (protected from smoke) to put on in the morning. Combined with morning showers I hope I didn't smell that much.
