The Myth
My house has a good ventilation system. Opening a window or turning on a fan will clear the air of smoke, right?

The Truth
Unfortunately, opening a window or turning on a fan can’t completely remove the poisonous chemicals in secondhand smoke from the air. In fact, not even the most expensive air cleaning systems are able to clear the air of all poisons in secondhand smoke.

Ventilating secondhand smoke does not do enough to protect kids. The only way to protect kids from secondhand smoke is to always smoke outside the home and outside the car.
