PET imaging shows greater lung inflammation in e-cigarette users than cigarette smokers

Electronic cigarette (e-cigarette) users have greater lung inflammation than cigarette smokers and non-smokers, according to a study. This study is the first to provide evidence that vaping e-liquids with e-cigarettes creates a unique inflammatory response in the lungs that is different from cigarette smoking.

E-cigarette usage has increased dramatically in the past several years, particularly among adolescents and young adults. While many people assume that e-cigarettes are safer than conventional cigarettes, e-cigarettes can cause pulmonary inflammation and increase the risk of lung disease. In addition, their long-term safety has not been rigorously evaluated.

This is the first PET study to use a novel radiotracer, 18F-NOS, to compare lung inflammation between cigarette and e-cigarette users in vivo. Although PET imaging with 18F-FDG has been used in the past to investigate inflammation in smokers and vapers, its conclusions were limited.

"iNOS is an enzyme that is overexpressed in e-cigarette users and cigarette smokers and is associated with acute and chronic inflammatory diseases," said Reagan Wetherill, Ph.D. "This makes it a relevant target for molecular imaging of lung inflammation and inflammatory lung disease."

E-cigarette users showed greater pulmonary inflammation than cigarette smokers and never-smoked/vaped controls. A positive association between pulmonary and peripheral measures of inflammation was also found, suggesting that e-cigarette use may increase pulmonary inflammation.

Jacob Dubroff, MD, Ph.D., sees a growing role for using molecular imaging to understand the effects of electronic cigarettes. He notes, "These findings suggest molecular imaging may be uniquely poised to detect and measure the potential pathophysiologic harms associated with electronic cigarettes, which have been touted as a safer vehicle for nicotine compared to traditional combustible cigarettes."

The current vape options cause more damage, strangely.

I see so many more people at this these days. They seem to think it’s cool. Bring back tobacco in pipes.

“Electronic cigarette (e-cigarette) users have greater lung inflammation than cigarette smokers...”

Hard to believe, but maybe so. I wonder how the cancer risks (vs. just inflammation) compare?

I wonder if the study differentiated between oil based products or water based products.

I don’t smoke but have friends and family who do.

You never know what shit is in the vapes.

For a while they were putting Vitamin E in them. That was killing people as it clogged the little sacks in the lungs.

I loved it when my dad smoked his pipe with cherry tobacco. Fond memory.

Obesity is a killer yet is considered body positivity. But by all means, ban vaping.

Nothing like the aroma of a pipe being smoked, second hands get to enjoy too.

I never understood the point of smoking not to mention it’s disgusting and smells. I grew up with parents that smoked during supper and a dad that would put his cigarettes out in whatever he was done eating.

So that had a big effect on wanting to smoke...🤢🤮

In his later years Rush Limbaugh was vaping. Maybe this killed him. Plus in many circumstances nicotine is a cancer accelerator. No matter where that cancer or pre-cancer might be in your body.

Yes Rush still smoked cigars. But gave up cigarettes for vaping for his nicotine fix.

Safe and Effective

I no longer trust the science or experts or any study. Look at the farce that were studies for HCQ or Ivermectin for COVID.

Not likely. Not likely at all.

All prior claims I have analyzed on e-cigarettes being worse than cigarettes have been found to be highly erroneous and biased.

This is likely the same fraud.

When we were teens we thought that smoking cigarettes would make us look cool — and it did!

Agreed, this study was probably done by big tobacco.
I don’t believe much of anything anymore.

Like I'm going to listen to medical advice from theses quacks when they also support the gene therapy injections.

Efficacy of Nicotine in Preventing COVID-19 Infection

Daily active smokers are infrequent among outpatients or hospitalized patients with COVID-19. Several arguments suggest that nicotine is responsible for this protective effect via the nicotinic acetylcholine receptor (nAChR).
Nicotine may inhibit the penetration and spread of the virus and have a prophylactic effect in COVID-19 infection.

SCREW THEM!
