Most U.S. adults call smoking "very harmful" and more than three out of four smokers want to kick the smoking habit, according to a new Gallup poll.

The poll was done by telephone in July — before the death of ABC news anchor Peter Jennings. About a thousand U.S. adults participated.

The findings:

— A quarter of those polled had smoked in the previous week.

— 22 percent were ex-smokers and 52 percent had never smoked.

— 81 percent called smoking "very harmful."

— More than half (53 percent) called secondhand smoke "very harmful."

Smoker's Results

Here are data on the 216 participants who are smokers:

— 76 percent stated that they wanted to quit smoking.

— 74 percent stated that they considered themselves addicted to cigarettes.

— More than half (58 percent) noted smoking less than a pack of cigarettes weekly.

— Heavy smokers were more likely to state that they were addicted to cigarettes.

— Heavy smokers weren't more likely to express a desire to quit smoking.

Smoking Affected Some Views

According to Gallup, 86 percent of nonsmokers called smoking "very harmful." Fewer smokers (65 percent) agreed.

Differing views also showed up in a 2001 Gallup poll. In that poll, 77 percent of nonsmokers agreed that smoking is a major cause of lung cancer, compared to 57 percent of smokers.

"As a group, smokers clearly recognize the risks inherent in their habit, but are perhaps less willing to admit it," states the latest Gallup report.

Big Changes Over Time

Fewer Americans smoke now than in the 1940s and 1950s.

In a 1944 Gallup poll, more than four in 10 participants (41 percent) said that they had smoked any cigarettes in the past week. That figure hit an all-time high in 1954, when 45 percent reported cigarette smoking in the previous week.

Today's smokers are also more likely to report smoking less than a pack of cigarettes per day, compared to those in the late 1970s and early 1980s, notes Gallup's report.
