Quitting reduces risk

Quitting and Reduced Risks Quitting smoking cuts cardiovascular risks. Just 1 year after quitting smoking, your risk for a heart attack drops sharply. Within 2 to 5 years after quitting smoking, your risk for stroke could fall to about the same as a nonsmoker’s. If you quit smoking, your risks for cancers of the mouth, throat, esophagus, and bladder drop by half within 5 years. Ten years after you quit smoking, your risk for lung cancer drops by half.
