If you only smoke a few cigarettes a day, it will damage your lungs as well as the burning of two packets.
- Columbia University experts tested the lung function of 25,000 volunteers a day – as a nonsmoker
- The decline was 7.65 ml / yr among those who drank five or fewer cigarettes a day
Light smokers damage their lungs just as much as addicts go through two packs of cigarettes every day, according to a study.
Doctors behind the Investigation Columbia University today states that lighting up on each day several times "is much riskier than many people think."
They tested the lung function of 25,000 volunteers, a mix of smokers and ex-smokers. Smokers and adults who had never blown on a cigarette.
The results showed that the lung function of heavy smokers – defined as smoking 30 per day – decreased more rapidly than non-smokers at a rate of 11.24 ml per year.
By comparison, the rate was lower. Among the lighter smokers, who drank less than five cigarettes a day, the drop was about 7.65 ml per year.
Doctors who stand behind research at Columbia University say glowing a few times a day is "a lot riskier than many People "think"
Experts believe that light smokers will lose the same lung capacity as heavy smokers in nine months within a year.
The lung function is a measure of the amount of air that a person can breathe in and out. From the 20s, of course, it decreases with age.
The main author Elizabeth Oelsner said, "Smoking a few cigarettes a day is much riskier than many people believe.
"The difference in loss of lung function between someone who smokes five cigarettes a day is relatively small compared to two packets a day.
"Everyone should be strongly encouraged to quit smoking, regardless of how many cigarettes a day he uses." The lung function caused by smoking does not normalize within a few years after giving up the lethal habit.
There has been a decrease in function of former smokers by 1.57 ml per year, which does not go back to zero for at least 30 years. the researchers claimed.
DO WE SMOKE LESS THAN BEFORE?
According to a study published in August, people in England today smoke 1.4 billion fewer cigarettes per year than at the beginning of the decade.
Investigations indicated stricter regulations for the packaging and advertising of cigarettes as well as for indoor smoking prohibition, have worked.
Around one in seven people in England smoke – but the study found that they consumed 24 percent fewer cigarettes than they did seven years ago.
The average number of cigarettes smoked per month fell by 118 million per month between 2011 and 2018, which is 1.42 billion fewer per year.
Dr. Oelsner said, "There are anatomical differences in the lungs that persist for years after smokers have stopped, and also the gene activity remains altered."
The study, in which scientists from a handful of institutions participated, was published in The Lancet Respiratory Medicine.
In a separate warning, the team also stated that light smokers may be at higher risk of fatal lung disease It has long been recognized that regular cigarette smokers are at risk for incurable chronic obstructive pulmonary disease (COPD).
Smoking is the most common cause of preventable cancer. It produces chemicals that cause at least 15 different forms of the disease.
People are attracted to smoking because nicotine makes them feel good, but it's easy to become addicted and very hard to quit when smoking becomes a habit.
About 7.4 million people in the UK regularly smoke tobacco, along with about one billion people – mostly men – worldwide.
Over the past 15 years, government initiatives to reduce smoking rates have been regularly launched in the UK.
Health warnings on packaging became mandatory in 2002, advertising was banned in 2003 and smoking prohibited indoors was banned in 2007.
Officials followed up on the measures in 2017 with a directive, which meant that all branded packaging had to be replaced by simple greenish-brown boxes.
