Lab Studies on Thirdhand Smoke Help Prompt Legislation

As reported by the Associated Press, the California Assembly approved a bill last week that would ban smoking inside home day care centers even after the children have left, a regulation that targets lingering “thirdhand smoke” and has been adopted by 12 other states. Smoking already is banned in homes that function as day care centers during their operating hours to prevent kids from being exposed to secondhand smoke. But recent research shows even off-hour smoking places children at risk. Berkeley Lab has been at the forefront of research on thirdhand smoke, first reporting on the hazard in 2010 with studies led by Hugo Destaillats, Mohamad Sleiman, and Lara Gundel. Last year, a study led by Bo Hang confirmed that thirdhand smoke causes DNA damage. More>
