New Device Equally Harmful as E-cigarettes

While we know about the harmful effects of traditional cigarettes and vaping, new heated tobacco devices are no less toxic to the human lung cells than ordinary cigarette smoke, said researchers, including one of Indian-origin.

The study has compared new heated tobacco devices, which heat solid tobacco instead of an e-liquid, with vaping and traditional cigarettes showing that all the three are toxic to the cells.

In addition, these newer electronic nicotine delivery devices can destroy lung tissue leading to fatal diseases such as chronic obstructive pulmonary disease, lung cancer and pneumonia, and can increase the risk of developing asthma.

“Smoking is the leading cause of preventable death, and with the introduction of e-cigarettes in the last decade, the trend of nicotine uptake is not going to slow down in the near future,” said Pawan Sharma, a researcher at the University of Technology Sydney.

“The latest addition in this emerging trend is the planned and vigorous introduction of heated tobacco devices. They are commonly called next generation or heat-not-burn products. We know very little about the health effects of these new devices, so we designed this research to compare them with cigarette smoking and vaping,” added Sharma.

For the study, researchers tested the effects of all three nicotine sources on two types of cells taken from the human airways: epithelial cells and smooth muscle cells.

In healthy lungs, epithelial cells act as the first line of defence to any foreign particles entering the airway while smooth muscle cells maintain the structure of the airway. However, smoking can lead to difficulty in breathing primarily by hampering the normal functions of these cells.

The team exposed the cells to different concentrations of cigarette smoke, e-cigarette vapour and vapour from a heated tobacco device, and measured whether this was damaging to cells and whether it affected the cells’ normal functions.

The findings, published in ERJ Open Research, showed that cigarette smoke and heated tobacco vapour were highly toxic to the cells both at lower and higher concentrations while e-cigarette vapour demonstrated toxicity mainly at higher concentrations.

Importantly, the review of the European Respiratory Society’s Tobacco Control Committee’s own data on these devices has shown that, in rats, there is evidence of lung inflammation, and there is no evidence of improvement in lung inflammation and function in smokers who switch to heated tobacco, said Professor Charlotta Pisinger from the varsity.

“If the current trend continues, tobacco use will cause more than eight million deaths annually by 2030 around the world,” noted Sharma. (IANS)

FDA Proposes to Curb Sales of Flavoured E-cigarettes to Teenagers

The US Food and Drug Administration (FDA) has proposed to curb sales of flavoured e-cigarettes to teenagers.

The health regulator on Wednesday said that it is proposing to end all flavoured electronic nicotine delivery system (ENDS) products such as electronic cigarettes, except tobacco, mint and menthol-flavoured products.

According to the Centers for Disease Control and Prevention, a total of 3.6 million middle and high school students reported using e-cigarettes last year.

“Evidence shows that youth are especially attracted to flavoured e-cigarette products, and that minors are able to access these products from both brick-and-mortar retailers, as well as online, despite federal restrictions on sales to anyone under 18,” FDA Commissioner Scott Gottlieb, said in a statement.

“With these concerns in mind, today, we’re advancing our policies aimed at preventing youth access to, and appeal of, flavoured e-cigarettes and cigars.”

The new proposed policy also subjects all manufacturers and retailers to FDA enforcement for selling certain flavoured ENDS products without authorisation.

The FDA had previously threatened to ban most flavoured e-cigarettes in 2017 but did not take any enforcement moves.

However, with the new policy, FDA intends to prioritise its enforcement to focus on protecting youth from becoming addicted to nicotine.

It believes, at the same time, “that ENDS products still hold promise to help transition currently addicted adult smokers to potentially less harmful sources of nicotine”, Gottlieb said.
