Thirdhand smoke can cause DNA damage

Posted: 6/26/2013


For the first time ever, thirdhand smoke has been found to cause significant amounts of damage to human cells. Thirdhand smoke is the toxic residue that attaches to almost all surfaces leaving a strong odor long after cigarette smoke has dissipated.

The researchers from Lawrence Berkeley National Laboratory also discovered in this study that chronic exposure caused more DNA damage than acute exposure. Samples exposed to chronic thirdhand smoke contained higher concentrations of chemical compounds than samples exposed to acute third-hand smoke. This suggests that as the smoke residue sits it becomes more harmful over time. Read more.
