Thirdhand smoke harmful to home prices and people

Homes that housed a regular smoker are worth, on average, 20 percent less than they would be otherwise, said a surveyed group of Ontario, Canada, real estate agents.

Not only that, but thirdhand smoke — smoke residue that has seeped into walls, carpets and the ventilation system of a home and become part of a home’s atmosphere — has been shown to be carcinogenic by researchers at the Lawrence Berkeley National Laboratory in California.
