Previous research found that older former smokers who had consumed less than 32 pack years of cigarettes could reduce their risk of dying from heart disease to the level of lifelong nonsmokers after 15 years. However a new study shows such recovery of heart can happen within 8 years. “The new finding is if you smoke less than 32 pack years, you might become like never-smokers much sooner than 15 years,” said Dr. Ali Ahmed. However, the report said even after 15 of quitting smoking, the risk of dying from lung cancer, emphysema or chronic obstructive pulmonary disease continues. “If you smoke, quit and quit early,” said Ahmed.
