After you quit

Let the healing begin

After you quit smoking, your body will immediately start to repair itself. Here's how.

After 24 hours:
The oxygen levels in your blood return to normal. The chance of heart attack is reduced.

After 1 to 9 months:
Circulation, smell, and taste improve. You have better lung function, more energy, and fewer colds.

After 1 year:
Your excess risk of heart disease is half that of a smoker.

After 5 years:
Your risk of stroke drops significantly.

After 10 years:
Your risk of getting lung cancer is half of what it would be if you were still smoking.
