The Great American Smokeout

By

The American Cancer Society marks the Great American Smokeout on the third Thursday of November each year by encouraging smokers to use the date to make a plan to quit, or to plan in advance and quit smoking that day. By quitting — even for one day — smokers will be taking an important step towards a healthier life – one that can lead to reducing cancer risk.

Tobacco use remains the single largest preventable cause of disease and premature death in the US, yet about 42 million Americans still smoke cigarettes — a bit under 1 in every 5 adults. As of 2012, there were also 13.4 million cigar smokers in the US, and 2.3 million who smoke tobacco in pipes — other dangerous and addictive forms of tobacco.

Why Quit?
The health benefits of quitting start immediately from the moment of smoking cessation. Quitting while you are younger will reduce your health risks more, but quitting at any age can give back years of life that would be lost by continuing to smoke.

When smokers quit, what are the benefits over time?

20 minutes after quitting
Your heart rate and blood pressure drop.

10 years after quitting
The risk of dying from lung cancer is about half that of a person who is still smoking. The risk of cancer of the larynx (voice box) and pancreas decreases.

These are just a few of the benefits of quitting smoking for good. Quitting smoking lowers the risk of diabetes, lets blood vessels work better, and helps the heart and lungs. Quitting while you are younger will reduce your health risks more, but quitting at any age can give back years of life that would be lost by continuing to smoke.
