A new study shows that tobacco smoke can leave a 30-year legacy on your DNA.

Nearly 16,000 blood samples from smokers, former smokers and non-smokers were analyzed.

Results found that tobacco smoke changes the DNA's chemical surface which in turn affects how particular genes function.

Experts hope the findings can be used to develop treatments for smoking-related diseases such as cardiovascular disease and lung cancer.
