Study showing how the vaping inducing the reactions in lungs; that can lead to cause of disease. Vaping is widely assuming to be safer than cigarette smoking; by this evidence suggesting that vaping promoting the same cellular responses; finding in smokers who suffering with emphysema. Finding that the lungs of vapers like the lungs of smokers have elevating levels of protease enzymes; a condition knowing to cause emphysema in smokers.
The researchers also found that the nicotine in vaping liquids is responsible for the increase in protease enzymes. But findings in this study indicate that vaping may not be safer than cigarette smoking; Disease Control and Prevention (CDC) has estimated that in 2014 about 9 million adults in the country were regular vapers and that close to 30 million had tried vaping at least once.
But vaping on this scale has been going on for less than a decade; and so the long-term health effects of vaping are not yet well understood. The three protease enzymes are neutrophil elastase and matrix metalloproteases 2 and 9. Immune cells in the lungs are knowing to secrete these enzymes at higher levels in a reaction to cigarette smoke.
Vaping inducing reaction
Chronic over activity of these protein chewing enzymes; damaging the tiny sensitive air sac structures in the lungs that allow people to breathe. In smokers, this damage is thought to be the causing of emphysema, a form of chronic obstructive pulmonary disease; (COPD) involving progressive shortness of breath and for which there is no cure.
The study also finding the evidence; that nicotine in liquids is the cause of the elevating-protease reaction. By administering nicotine to immune cells cultured in the laboratory at concentrations like those seen in vapers sputum and lung fluid they observing that the cells overproduced the proteases. And this overproduction increasing; when the researchers exposed the immune cells to higher nicotine levels.
Burning of tobacco leaves
Vaping is thought to be much safer than cigarette smoking; which involving the high-temperature burning of tobacco leaves and the creation of toxic and carcinogenic combustion products. Some researchers have urged that smokers switch to vaping as a much less harmful alternative. The jury is still very much out when it comes to cancer risk associated with vaping.
But this latest study suggests that the potential harm of vaping may have been underestimating; especially when it comes to emphysema and COPD, two of the most common debilitating conditions historically associated with smoking. Moreover, a study from Tarran’s lab last year found evidence of toxic compounds in commonly used liquids, and the CDC currently is investigating about 100 recent cases in the U.S. of sudden, serious lung disease in otherwise healthy young vapers.
