People who smoke cigarettes for a living often have to deal with the consequences of a lifetime of addiction.
Smoking can lead to lung cancer, heart disease, stroke and death, according to the Centers for Disease Control and Prevention.
Many smokers can’t quit, and they often get hooked on the addictive tobacco.
But a new research paper suggests that if you don’t smoke, you may be less likely to develop chronic obstructive pulmonary disease (COPD), an underlying lung disease that affects more than 10 million Americans and costs the nation about $1.3 trillion a year.
This study found that people who smoked a lot, but did not quit, were less likely than those who did not smoke to develop COPD.
The paper was published in the journal Circulation, and it focused on a group of people who smoke more than two packs a day, but never quit.
According to the CDC, the U.S. now has about 6.5 million people with COPD, and the death toll has been rising in recent years.
According to a report released last year, the number of COPD cases is increasing in every state, with an estimated 2.4 million people diagnosed and 1.8 million dying in the U!
The study involved 2,000 people over a four-year period.
The study participants smoked at least one pack a day for at least two years, and were asked to report their smoking habits to a survey.
Participants who did manage to quit were then asked to complete a questionnaire about their experience with chronic obstructing pulmonary disease.
The questionnaire included questions about smoking history, lifestyle, and symptoms of COPDs.
The study found there was no difference in the likelihood that the participants who smoked more than a pack a week had developed COPD between those who had never smoked or never smoked more then two packs per day and those who were never smokers.
Researchers found that participants who were also taking other medication that affects inflammation and reduces inflammation in the lungs were also less likely, on average, to develop the disease.
The research team said the results are not surprising, given that smoking is a major risk factor for COPDs, and people who do not smoke have a higher risk of developing COPDs than those with a chronic disease.
In the study, participants were followed for four years.
Participants who did smoke more then 2 packs a week were still less likely for COPD to develop, compared to those who never smoked and never smoked two packs or more a day.
The researchers found that quitting smoking for at a high level did not increase the likelihood of developing the disease, but it did reduce the odds of COPDS.
The authors suggest that people with asthma, COPD and other chronic diseases that make it difficult to breathe should consider quitting cigarettes to reduce the risk of COPEs.
The new study found no difference between smokers who quit smoking and never smokers, but smokers who smoke twice a day or more were more likely to have developed COPDs compared to never smokers who did this.
According the researchers, the findings do not rule out the possibility that smoking could help people with lung problems like COPDs get better and have fewer COPDs in the future.
