Editor's note: This post is part of theÂ Overheard on CNN.comÂ series, a regular featureÂ that examines interesting comments and thought-provoking conversations posted by the community.
A federal campaign called "Tips from Former Smokers" is intended to educate Americans about the dangers of smoking. Readers talked about the ads, and they talked about smoking and other health issues.
Some debated whether smoking or obesity should be bigger health concerns.
trncell: "So when is the CDC going to put graphic pictures of open heart surgery on the doors of fast food restaurants? #1 killer in America: Heart disease. Your daily reminder."
iBod: "Heart Disease is often a result of smoking, as well, don't forget.....Not just the intake of food your body is already evolved to digest. That's not to say fast food is not a problem–it is for those who eat it maybe once or twice a week, every week of every year of their life. Smoking has a far greater impact on heart disease than fast food.
This reader said people are unfair to smokers.
KiM3695: "I am so sick of people and companies singling out cigarette smoking. Why not do some graphic ads about drinking? It's worse than smoking. Or put some ads out about fattening foods, since our country is the most overweight in the world. I am sick of this firestorm on adult tobacco users. Cigarettes are legal, people need to get over that."
But another wondered why people don't stop. FULL POST
Afghanistan drawdown - President Barack Obama will announce Wednesday how many U.S. troops he'll bring home from Afghanistan when the drawdown begins next month. Obama is expected to announce the approval of a plan that would result in 30,000 U.S. "surge" forces being withdrawn by the end of 2012, an administration official told CNN. There are about 100,000 U.S. troops serving in Afghanistan, including the so-called surge ordered in 2009 in a bid to control violence there.
Huntsman as GOP candidate - Former Utah Gov. Jon Huntsman is set to announce Tuesday his candidacy for the Republican presidential nomination. He's a motorcycle-riding Mormon who speaks fluent Mandarin, a soft-spoken father of seven with eclectic political connections. He was ambassador to China for President Barack Obama, whom he once described as a remarkable leader. That could make the primary season difficult for him.
Three things you need to know Tuesday.
