E-cigarette use causes chronic intestinal inflammation

Scientists from the University of California at San Diego have discovered an unexpected fact - the vapor from the vape generates inflammatory processes in the human body.

If you remove all additives and flavors from the vaping liquid, then propylene glycol and vegetable glycerin will remain in the "pure steam". Both substances are toxins, but very weak, and therefore officially approved for use in cosmetics and medicines. First of all, this applies to the skin of a person, the lungs are also slightly affected by inhalation of steam, but the intestinal mucosa is unexpectedly under threat.

The epithelial lining of the intestinal wall is a unique and highly vulnerable structure. Its thickness is only one layer of cells through which nutrients are absorbed, but at the same time it is also a barrier to trillions of microbes. Research from 2018 showed that vaping vapor does not affect the gut microflora, but recent experiments have revealed that the lining itself suffers when exposed to it.

The scientists used models of intestinal mucosa grown from stem cells. In both mouse tissue and human cells, steam fumigation of the vape for three months resulted in multiple foci of inflammation. The toxic vapor destroys some proteins and makes the lining's physical barrier vulnerable to bacterial infections. This is only the first study in this direction, scientists are not rushing to conclusions, but it is obvious that the "safety" of electronic cigarettes is greatly exaggerated.
