Maybe the Great American Smokeout is for you. It’s an opportunity to join with literally millions of other smokers in saying “no thanks” to cigarettes for 24 hours.The Great American Smokeout traditionally takes place on the third Thursday in November. The concept dates from the early ’70s when Lynn Smith, publisher of the Monticello Times of Minnesota, announced the first observance and called it “D Day.” The idea caught on in state after state until in 1977, it went nationwide under the sponsorship of the American Cancer Society. In the past, as many as one-third of the nation’s 46 million smokers have taken the day off from smoking. The rules are simple: You quit smoking for the 24 hours of the Smokeout. You won’t be alone; you can swap advice, jokes and groans with the other “quitters,” nonsmokers and volunteers who will be cheering you on.
