The dangers of flavored e-liquids?

It was previously thought that the dangers of flavored e-liquids were only attracting minors to vape. However, it was not that simple. Recently, a research team from the University of California San Diego School of Medicine, the Royal Adelaide Hospital and the University of Adelaide School of Medicine in Australia The latest research, published in the American Journal of Physiology, reveals that the flavoring chemicals in vape vapors can be extremely damaging to the lungs, with or without nicotine.

Laura Crotty Alexander, associate professor at the University of California, San Diego School of Medicine, said: "99% of e-liquids are flavored e-liquids, and tobacco-flavored e-liquids make up only a small portion and are only purchased by users who are originally smokers. To make e-liquid have a more perfect taste, e-liquid manufacturers have added various chemicals to it. These chemicals are toxic to the lungs, and when inhaled, wreak havoc on the lungs and affect special proteins level, and maintaining this level helps the body's immune system function properly."

The research team studied 21 people who vape and found changes in disease-causing inflammatory proteins, with more irregular protein levels in each vape's saliva and respiratory system compared to those who did not vape. The scientists then used in vitro experiments to observe how human airway cells responded to the vapors of 10 flavored e-liquids, and found that all e-liquids damaged the cells, and some flavors were more toxic than others. The researchers said the overall study data showed that each vape caused damage to the lungs, with flavor chemicals such as chocolate and bananas being the most toxic.

Author Dr Miranda Ween said: "The degree of virulence and bacterial clearance by alveolar macrophages is influenced by almost every vape flavour. The chocolate has an unexpectedly high impact, killing nearly all cells and preventing macrophages almost completely. Phages clear bacteria." Crotty Alexander said: "Alveolar macrophages are one of the most important immune cells in our lungs, maintaining homeostasis. When vape vapors are toxic, these cells trigger an inflammatory response that disrupts the body's immune system. homeostasis, leading to disease and lung injury."

Ween thinks the easiest way to redefine the taste of the vape is to limit e-liquids to a single flavoring chemical that has been tested and determined to be safe in concentrations. Sadly, such research is scarce compared to the worldwide popularity of the vape.

It seems that it is very reasonable for both the United States and China to ban flavored e-liquids. At the same time, I also hope that more authoritative organizations can invest in vape safety testing. After all, it is impossible for all flavored e-liquids to be harmful. , we also hope to find a safe flavored e-liquid, or formulate corresponding standards, only allowing safe flavored e-liquid to be produced, so as to truly meet the needs of the total users, not to talk about changes, just because of some flavors Banning all flavored e-liquids because of the dangers of e-liquids is not very comfortable either.
