New Vaping Technology Allegedly Doesn’t Have as Much Toxicants as the Cigarette Smoke

A vapor product that has some new technology has a rather large extent of fewer and lower levels of specific toxicants in comparison to cigarette smoke, new research says.

Scientists from British American Tabacco (BAT) carried out a series of chemistry tests created to look for certain elements in the vapor from iSwitch, BAT’s new vapor item, which utilizes a stainless-steel blade to heat e-liquid. The discharges from the product were compared to those from another cigarette, 1R6F.

The results were published today in the journal Chemical Research in Toxicology and depict the iSwitch vapor as having fewer and lower levels of particular toxicants than cigarette smoke. Some toxicants from cigarette smoke are not found in iSwitch vapor at all, and others are reduced by about 99 percent.

“We are constantly innovating to seek to expand our potentially reduced-risk product portfolio,” says Dr. Chris Proctor, Group Head of Potentially Reduced-Risk Product Science at BAT.

A Different System

Most common vaping devices are created through a coil-and-wick system in which e-liquid is drawn up from a storage place by a cotton wick. Around the wick, there’s a metal coil, which, when heated, transforms the liquid into vapor.

This vapor reportedly has fewer and lower levels of some substances than cigarette smoke. Still, some low-quality coil-and-wick systems can dry out or overheat. This can trigger the thermal breakdown of humectants in the e-liquid, which leads to the development of toxic elements, such as carbonyls.

iSwitch blade made of stainless steel replaces the coil-and-wick system, and it is continually given e-liquid by a capillary system. This means the PureTech blade cannot overheat or dry out, therefore, overcoming the issue of dry-wicking.

“As well as improving the performance of vaping devices, PureTech lessens the risk of humectant thermal breakdown, further reducing emissions of potentially harmful substances,” says Chuan Liu, Senior Principal Scientist at BAT.

“This was reflected in our study, which showed that, even when used at high power settings, iSwitch emissions contain no or extremely low levels of analytes.”

Human surveys are required to further back up the results of this research.
