Benefits of Quitting

When you stop using tobacco, your body begins to heal almost immediately. Here are some of the benefits of being smoke-free.

Within 20 minutes
Your heart rate and blood pressure drop toward normal levels.

Within 8 hours
The carbon monoxide level in your body drops, and the oxygen level increases.  (Carbon monoxide in cigarette smoke steals oxygen from the blood cells.)

Within 12 hours
The carbon monoxide level in your blood reaches a normal level.

Within 48 hours
Your chances of having a heart attack decrease. Your sense of taste and smell begins to improve.

Within 72 hours
Your bronchial tubes begin to relax and make it easier for you to breathe. Your lung capacity increases.

Within 2 weeks to 3 months
Your circulation improves (circulation is constricted by cigarette smoke). Up to 30% of your lung functioning increases.

Within 1 to 9 months
Coughing, sinus congestion, and shortness of breath improve. You begin to feel less tired. Cilia (the tiny hair-like structures in your nose and lungs) begin to grow back and are able to clear mucus and other dirt from the lungs and nose and reduce the risk of infection.

Within 1 year
Your risk of heart disease decreases to half that of a smoker’s.

Within 5 to 15 years
Your risk of stroke is reduced to that of a nonsmoker.

Within 10 years
Your risk of lung cancer is one-half that of a smoker’s. Your risk of cancer of the mouth, throat, esophagus, bladder, cervix, and pancreas decreases.

Within 15 years
Your risk of coronary heart disease is equal to that of a person who never smoked.

It’s never too late to quit using tobacco.
