Driving a car that used to belong to a smoker, and smelling the lingering fumes is annoying to some people, but now scientists say it can actually be dangerous.
Second-hand smoke is smoke in the air that another person can inhale, and it has been shown to cause all kinds of health problems from cancer to asthma.
Third-hand smoke refers to the smell or fumes that linger on a person after they have smoked, were in a smoking area like a bar, or smoked in a car.
Now, the American Lung Association says those lingering fumes and chemicals can cause health problems to others near the smokers.
Children who breathe in these fumes or smells have an increased risk of infections in their ears, lungs or throat, and can contribute to asthma.
