NEW YORK (AP) — Government health officials launched the second round of a graphic ad campaign Thursday that is designed to get smokers off tobacco, saying they believe the last effort convinced tens of thousands to quit.

The ads feature sad, real-life stories: There is Terrie, a North Carolina woman who lost her voicebox. Bill, a diabetic smoker from Michigan who lost his leg. And Aden, a 7-year-old boy from New York, who has asthma attacks from secondhand smoke.
