I grew up in a home with heavy smokers, so I really had no chance at all as a kid. I have childhood memories of being in a smoke filled car with windows rolled up. Didn't even have to crack the windows because there were ashtrays built into the cars of that era. And then if the windows were open or cracked, there was another danger. I lost count of how many times I had ashes fly back into the back of the car directly into my eyes and mouth, or the lovely feeling of a burning "cherry" searing into my forehead.
