UNDATED - Thursday marks the 34th annual Great American Smokeout.
The Smokeout is sponsored by the American Cancer Society and encourages smokers to use the day to make a plan to quit, or to plan in advance and quit smoking that day.
Researchers say quitting smoking can increase life expectancy.
Smokers who want to quit can call the American Cancer Society Quit for Life Program operated and managed by Free & Clear at 1-800-227-2345 for tobacco cessation and coaching services that can help increase their chances of quitting for good.
