Editor's note: This post is part of the Overheard on CNN.com series, a regular feature 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.
golfman72: "Look everyone knows what happens when you continue to smoke, yet many still do. If those who continue to smoke then they will surely die, and there is NOTHING you can do to stop them, it all comes down to ones choice. Why continue to spend money on this to change people? NO ONE CAN CHANGE ANOTHER, only YOU can change yourself!"
