North Carolina, October 23, 2017 : Vaping and e-cigarettes comprise a considerably new trend in the market, having been around for only for a decade or so. While their use has not been widespread, with mostly the younger population choosing it, a majority of the people are not even aware about it. However, out of those who know, it is a common belief that e-cigarettes are a healthier alternative to regular smoking.

Contrary to regular cigarettes that burn tobacco, e-cigarettes deliver nicotine to the smoker in the form of water vapor. Due to this diluted consumption, most people imagine vaping is healthier than smoking. But is that really true?

While it will not be wrong to say that e-cigarette vapor smoke does not contain the same composition and amount of carcinogenic compounds as regular cigarette smoke, a new research suggests that ‘vaping’ may have its own harmful effects.

According to researchers from the University of North Carolina, the use of e-cigarettes can lead to inflammatory lung disease, triggered by extremely harmful response in the lung to the vapor smoke.

The Study Findings 

For the study that has been published in the American Journal of Respiratory and Critical Care Medicine researchers examined the sputum samples of 44 non-smokers, e-cigarette users, and current cigarette smokers. Sputum is a combination of saliva and mucus, coughed from the respiratory tract which is often caused by some infection or disease.

  • Analysis found that the batch of e-cigarette smokers had a significant increase in neutrophil granulocyte- and neutrophil-extracellular-trap (NET)-related proteins, which are our immune system’s first line of defense against infection causing pathogens.
  • However, it was also revealed that while neutrophils are helpful in combating infectious pathogens, they are also known to contribute to lung diseases like COPD (a group of lung diseases that block the air flow, making it difficult to breathe) and cystic fibrosis (a life threatening disorder that gravely damages the lungs and the digestive system).
  • Additionally, the researchers also identified a similar positive trend in specific biomarkers of oxidative stress between e-cigarette users and regular cigarette smokers that have been understood as causative of lung diseases.
  • Furthermore, common increase in mucinn 5AC, which is associated with asthma and chronic bronchitis, was revealed in both, e-cigarette and cigarette users.

While smoking, in any way, is harmful, it is  important to note here that regular cigarette smoke and vapor smoke are two different compounds which can (and do) have different effects on the body. According to Dr. Mehmet Kesimer, senior author of the new study, “Comparing the harm of e-cigarettes with cigarettes is a little like comparing apples to oranges.”

The senior researcher added that the research shows that e-cigarettes have a signature of harm in the lung, which is very similar to that of regular cigarettes, but also unique in its own way. A broader understanding of the harm done by vapor smoke can thus, have implications that challenge the popular belief that it is healthier alternative to consume vapor smoke from e-cigarettes than regular smoking.

It must be noted here that this study was carried out on a small and limited scale, with most e-cigarette smokers previously being cigarette smokers. This duplicity makes it difficult to clearly identify if the study results are strictly related to use of e-cigarettes and vapor smoke.

There have been numerous studies about the harm of e-cigarettes in relation to that of regular cigarettes. However, what makes the study extremely important is its analysis of the unique or novel ways that e-cigarettes could be causing harm to our bodies.

In increasing number of studies previously published have revealed how it is a healthier lifestyle choice to switch from regular cigarettes to e-cigarettes. But, new researches have begun to trace the long-term adverse effects of e-cigarettes, which are challenging this switch.

If you are still wondering, the only completely healthy alternative to cigarette smoking is to completely quit smoking.

Cigars, Pipes Tied To Same Risks As Cigarettes

Traditionally, doctors have asked just whether people smoked cigarettes, but they should instead be questioning patients more broadly about tobacco use

  • Cigarettes are not the only tobacco products which can cause death
  • Other tobacco products like cigars and pipes are just harmful
  • All these tobacco products can cause cancer

Cigarettes are not the only type of tobacco products that can lead to premature death or fatalities from smoking-related cancers, a U.S. study confirms.

While people who exclusively smoke cigarettes have twice the risk of premature death from all causes compared to people who avoid tobacco altogether, exclusive cigar smokers have a 20 percent higher risk of early death, researchers report in JAMA Internal Medicine.

When it comes to fatalities from specific cancers that have been tied to tobacco use, cigarette smokers have four times the risk of people who never used tobacco, but cigar smokers are 61 percent more likely to die of these cancers and pipe users have 58 percent higher odds.

“We knew exclusive users of cigars and pipes were at greater risk of disease than people who do not use tobacco,” said lead study author Carol Christensen of the U.S. Food and Drug Administration’s Center for Tobacco Products. “However, this study provides information that reflects today’s patterns of tobacco use.”

These data “underscore the importance of complete quitting,” Christensen said by email.

For the study, researchers examined nationally representative survey data, collected starting in 1985, from 357,420 participants who were followed through 2011.

Overall, 203,071 people, or about 57 percent, never used tobacco at all. Another 57,251 participants were current daily cigarette smokers, while 9,414 said they had a less frequent habit and 77,773 were former cigarette smokers.

In addition, 531 people were current daily cigar smokers, while 608 individuals used cigars less frequently and 2,398 had quit.

For pipes, 1,099 participants had a current daily habit, while 78 people used pipes less often and 5,237 had quit.

During the study period, 51,150 people died of all causes.

With a daily cigarette, cigar or pipe habit, people had an elevated risk of death from tobacco-related cancers including malignancies of the bladder, oesophagus, larynx, lung, mouth and throat, and pancreas.

Nondaily users

Even with a nondaily cigarette habit, people were more than six times more likely to die of lung cancer than individuals who never used tobacco. They also had more than seven times the risk of dying from a chronic obstructive pulmonary disease, more than four times the odds of death from oral cancers, and 43 percent higher odds of death from a circulatory system disorder.

Current cigar smokers had more than three times the odds of dying of lung cancer, and for current pipe smokers, the risk was 51 percent higher, compared with never-smokers.

The results were limited, however, by the relatively small numbers of cigar and pipe smokers in the sample, the authors noted.

Cigarettes, hookah, pipes, cigars all are equally harmful.

Another limitation was that survey questions about tobacco use changed over time and didn’t determine how often nondaily smokers might have used cigarettes, cigars or pipes.

Even so, the results suggest that doctors may need to broaden how they discuss smoking with patients to make sure people understand they’re at risk even when they don’t have a daily habit, said Dr. Michael Ong of the University of California-Los Angeles and VA Greater Los Angeles Healthcare System.

“Patients often do not associate the occasional use of cigar or pipes with health risks, but this study shows that current, particularly daily, cigar use is associated with increased overall risk of death,” Ong, who wasn’t involved in the study, said by email.

Doctors also need to broaden their message about smoking and cigarettes to include other tobacco products that are becoming more popular, said Judith Prochaska, a researcher at Stanford University in California who wasn’t involved in the study.

Traditionally, doctors have asked just whether people smoked cigarettes, but they should instead be questioning patients more broadly about tobacco use, Prochaska said by email.

“The tobacco landscape has been changing dramatically,” Prochaska added. “While cigarettes remain the primary tobacco product used, cigars, smokeless tobacco, e-cigarettes, hookah, and even pipe tobacco have seen gains in use, while cigarette use in the U.S. has been declining.” VOA
