The only real way to protect yourself and others from thirdhand smoke is to create a smoke-free environment.
Who is in the most danger when it comes to thirdhand smoke? Infants and small children.
According to Scientific American, children ingest twice the amount of dust that adults do, and will likely get 20 times the exposure to dangerous chemicals and pollutants because of their proximity to contaminated surfaces.
Kids play on the floor and climb on the furniture. Babies put anything and everything they can in their mouths. Their small size makes them more vulnerable to environmental hazards such as thirdhand smoke.
How can you or your loved ones avoid exposing and endangering your small children? Do not allow others to smoke in your home or car, and ask others not to smoke near you or your children. Smoke outside of the home and wear the same "smoking clothes." Change clothes when you re-enter the home, and wash your hands and face.
