Consumer Health: What are the dangers of thirdhand smoke?
The residual nicotine and other chemicals left on indoor surfaces by tobacco smoking is called thirdhand smoke.

Children and nonsmoking adults might be at risk of tobacco-related health problems when they come in contact with this thirdhand smoke residue.
