Corpses¹, cancer patients and diseased lungs are among the images the federal government plans for larger, graphic² warning labels that would take up half of each pack of cigarettes sold in the United States.

Three examples of proposed warning graphics that will appear on cigarette packs as part of the government\s new tobacco prevention efforts, seen in Washington, on Wednesday.

Whether smokers⁴ addicted⁵ to nicotine⁶ will see them as a reason to quit remains⁷ a question.

The images are part of a new campaign announced by the Food and Drug Administration and the Department of Health and Human Services on Wednesday to reduce tobacco use, which is responsible for about 443,000 deaths per year.

"Some very explicit⁸（明确的，直率的） , almost gruesome（可怕的，阴森的） pictures may be necessary," FDA Commissioner⁹ Margaret Hamburg said. "This is a very, very serious public health issue, with very, very serious medical consequences," such as cancer, heart disease, strokes and lung diseases.

The share of Americans who smoke has fallen dramatically since 1970, from nearly 40 percent to about 20 percent, but the rate has stalled since about 2004. About 46 million adults in the US smoke cigarettes.

In the same period, the average cost per pack has gone from 38 cents to $5.33. Much of those increases are from state and federal taxes.

It's unclear why declines in smoking have stalled. Some experts have cited tobacco company discounts or lack of funding for programs to discourage smoking or to help smokers quit.

The new prevention plan is part of a law passed in June 2009 that gave the FDA authority to regulate tobacco, including setting guidelines for marketing¹⁰ and labeling, banning certain products and limiting nicotine. The law doesn't let the FDA ban nicotine or tobacco.

The FDA is proposing 36 labels for public comment. They include phrases like "Smoking can kill you" and "Cigarettes cause cancer" and feature graphic images to convey（传达） the dangers of tobacco.

Some of the labels include a man with a tracheotomy（气管切开术） smoking a cigarette, a cartoon of a mother blowing smoke in her baby's face, rotting and diseased teeth and gums（牙龈，牙床） , as well as cigarettes being flushed down the toilet to signify quitting.

The new warning labels are to take up the top half of a pack - both front and back - of cigarettes and contain "color graphics depicting¹¹ the negative health consequences". Warning labels also must constitute 20 percent of advertisements.
