By Molly Clifton

A new study finds smoking can affect veins in the leg even a year after a person quits.

Researchers in China looked at more than 200 patients who had heart bypass operations.

That's when surgeons graft leg veins from a patient to use in their heart.

Scientists found that the veins in smokers did not normalize even a year after quitting and many times the vein failed in the heart.
