What does this tool help you learn?

This tool can be used to estimate the impact that smoking will have on your lifespan. Based on the number of cigarettes you smoked in the past and how many you will smoke from now until the date you plan to quit, this tool estimates how many years the damaging effects of smoking may take away from your life.

What does your score mean?

The damage caused by smoking varies from person to person. This tool uses an estimate based on statistical averages to increase your awareness of how smoking may be impacting your life.

This tool doesn't calculate the long-term impact that smoking will have on the quality of your life and the lives of people you care about. The disabling effects of smoking-related illnesses such as heart disease, cancer, or emphysema can cause significant suffering and medical expense, regardless of whether they directly affect the number of years of your life.

How much time smoking takes from your life also depends on lifestyle choices other than smoking, such as eating habits and exercise. These things may increase or decrease the amount of time your life will be shortened by smoking.

What's next?

Quitting smoking can be difficult, especially if you have been smoking for a long time. It may take several tries before you succeed. But even if you have a strong dependence on nicotine, it's still possible to quit. And even if you have smoked for many years, quitting smoking now can still increase your lifespan and improve the quality of your life.

The best way to stop smoking is to get help and to follow a plan. You can increase your chances of quitting if you:

• Take medicines, such as bupropion (Zyban) or varenicline (Champix).
• Use nicotine replacement therapy (gum, lozenges, patches, or inhalers).
• Get counselling (by phone, group, or one-on-one).

Taking medicine while also getting counselling works even better for quitting smoking.
