Thirdhand smoke is a toxic residue that sticks to surfaces and objects. People come into contact with thirdhand smoke when their skin touches a surface where thirdhand smoke has collected, when they breathe in thirdhand smoke chemicals that are in the air, and when they swallow residue that are on objects that they put in their mouths. Thirdhand smoke residue can enter modes of transportation, such as cars, buses, trains, and planes, from either someone having smoked inside the vehicle or from the clothes, hair, or skin of someone who has been exposed to tobacco smoke.
