If You Gain Weight After Smoking, Does it Cancel Out the Benefit of Quitting?


By Molly Clifton

Americans gain an average of six to 13 pounds after they quit smoking.

Researchers wanted to know if the extra weight, which is a known risk factor for heart disease, cancels out the benefits of quitting.

They found smokers who gave up the habit lowered their risk of cardiovascular disease more than 50 percent, despite gaining significant weight.

The study is in the Journal of the American Medical Association.
