Thirdhand smoke lingers in casino months after smoking ban

(San Diego State University) Decades of smoking in casinos causes the massive buildup of toxic residue on walls, furniture, and in carpets, according to a new study led by scientists at San Diego State University. The researchers found that the residue, known as thirdhand smoke, declined significantly after smoking was banned in a Northern California casino. But even six months later, toxic tobacco smoke residue remained above levels found in hotels or private homes with smoking bans.
