All nicotine devices as toxic to the lungs as cigar tees are

A study comparing new heated tobacco devices, vaping and cigarettes shows that all are equally harmful

A new study comparing the new smoking devices with vaping and traditional cigarettes shows that all three are toxic to human lung cells.

The study published in ERJ Open Research suggests that the new device, which heats solid tobacco instead of an electronic liquid, is no less toxic to cells than ordinary cigarette smoke.

According to researchers, the study adds that these new electronic devices for nicotine delivery may not be a safer substitute for smoking.

The study was led by Dr. Pawan Sharma, a researcher at the Sydney University of Technology and the Woolbad Institute of Medical Research in Sydney, Australia.

"What stands out is that new products are by no means less toxic to cells than conventional cigarettes or e-cigarettes."

He said: "Smoking is the leading cause of preventable death, and with the introduction of electronic cigarettes over the past decade, the trend of nicotine absorption is not going to slow down in the near future . If the current trend continues, smoking will cause more than eight million deaths a year by 2030 in the world. "

India has already started a process to limit the availability of ENDS throughout the country.

Sharma added, "The latest addition to this emerging trend is the planned and vigorous introduction of heated tobacco devices. They are commonly called next-generation products or products that do not burn. We know very little about the effects of these new devices on health. So we designed this study to compare it with cigarette smoking and smoking. "

The researchers tested the effects of the three sources of nicotine on two types of cells taken from the human airways: epithelial cells and smooth muscle cells. In healthy lungs, epithelial cells provide the first line of defense against foreign particles entering the airways, while smooth muscle cells maintain the structure of the airways. However, smoking can cause breathing difficulties mainly by hindering the normal functioning of these cells.

Dr. Sharma and his team exposed the cells to different concentrations of cigarette smoke, electronic cigarette vapors and heated tobacco vapors, and determined whether it damaged the cells and whether it affected the normal functions of these cells. this.

The researchers found that cigarette smoke and heated tobacco vapors were highly toxic to cells at lower and higher concentrations, while vapors from electronic cigarettes showed toxicity primarily at higher concentrations. The researchers say these concentrations represent the levels of nicotine found in chronic smokers.

Dr. Sukhwinder Sohal, a researcher at the University of Tasmania, Launceston, Australia, and lead author of the study, said, "We have observed different levels of cellular toxicity with all forms of cancer. exposure in human lung cells. What stands out clearly is that new products are by no means less toxic to cells than conventional cigarettes or e-cigarettes. "
