Amazing: Here's what happens to your body after 25 years of quitting.

One study shows that smoking risks exist 25 years after quitting.

So far it has been widely believed that quitting tobacco reduces the risk of cardiovascular disease, heart attack, and many forms of cancer.

However, the new study argues that the risk of cardiovascular disease can be maintained 25 years after the last cigarette.

Doctors believe that from the early years of the break of tobacco, life expectancy increases significantly.
