Third-hand smoke causes significant DNA damage - new study
LOS ANGELES (KABC) -- According to a new study, it's not second-hand smoke but third-hand smoke we need to worry about.
Third-hand smoke is the residue that clings to surfaces long after the second-hand smoke from a cigarette has cleared out.
Now, researchers say third-hand smoke causes significant genetic damage in human cells.
They also found that chemicals in samples exposed to chronic third-hand smoke exist in higher concentrations and cause more DNA damage, than samples exposed to acute third-hand smoke.
Researchers say the results of the study suggest residue becomes more harmful over time.
