If you continue to smoke, you have a 50% chance of dying early
because of your smoking. On average, people who smoke die nearly 14 years
earlier than people who do not smoke.1
Quitting smoking will add time to your life no matter how old you are
or how long you've been smoking, because quitting smoking reduces your risk for
life-threatening health problems. The amount of time you will gain
depends on how long you've been smoking, how many cigarettes you smoke each
day, and whether you already have other health problems when you quit.
For those who quit smoking before age 35, almost
all of the disease risk from smoking is eliminated.
If you quit smoking before you turn 50, your risk of dying in the
next 15 years is half that of a person who continues to smoke after age
Even men and women who quit at age 65
to 69 increase their life expectancy.
People who have become seriously ill because they smoke have a chance
to live longer and are less likely to develop dangerous infections, such as
pneumonia, if they quit.
