How does smoking affect your family and other people?

Secondhand smoke is a combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers. Environmental Tobacco Smoke (ETS) exposes non-smoker even if the smoker does not light up in not light up in front of non-smokers, or if they ventilate the enclosed space they are lighting up in.
