A new study has pitted e-cigarettes against their traditional counterparts to gauge how well they perform in indoor spaces – and, it appears vaping really does have less of an impact on the surrounding air. While particles from conventional cigarette smoke linger in the air for upwards of 45 minutes, researchers found that those stemming from e-vapor products evaporate within seconds, even indoors.
Even in the ‘worst case scenario,’ where there was no ventilation, the researchers found the particle counts quickly returned to background levels in trials with commercially available vapes.
While particles from conventional cigarette smoke linger in the air for upwards of 45 minutes, researchers found that those stemming from e-vapour products evaporate within seconds, even indoors.
The new research comes as part of a collaboration between Kaunas University of Technology in Lithuania, the Swiss Federal Laboratories for Materials Science and Technology, ETH Zurich, and Fontem Ventures. Participants, who were already regular vapers, were tasked with using their devices under varying conditions of ventilation. Researchers then measured how particle concentrations changed in the surrounding air. Within seconds, the researchers found the liquid aerosol droplets evaporated, bringing the space quickly back to the normal levels.
‘No accumulation of particles was registered in the room following subjects’ vaping,’ says Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures.
‘This shows us how fundamentally different exhaled e-vapor particles are compared to those released when smoking conventional cigarettes, the latter of which linger in the air for longer periods of time.’ Immediately after the participants exhaled, the researchers say particle concentrations for e-cigarettes were in the same order of magnitude as those seen with traditional cigarettes.

An electronic cigarette (e-cigarette) is a device that allows users to inhale nicotine by heating a vapour from a solution that contain nicotine, propylene and flavourings.
As there is no burning involved, there is no smoke like a traditional cigarette.
But while they have been branded as carrying a lower risk than cigarettes, an increasing swell of studies is showing health dangers.
E-cigarettes do not produce tar or carbon monoxide, but the vapor does contain some harmful chemicals.
Nicotine is the highly addictive chemical which makes it difficult for smokers to quit.
Nearly three million people in Britain use e-cigarettes, and more than nine million Americans.
1. Standard e-cigarette
Battery-powered device containing nicotine e-liquid. It vaporizes flavored nicotine liquid.
Very similar to normal e-cigarettes but with sleeker design and a higher concentration of nicotine. Thanks to its ‘nicotine salts’, manufacturers claim one pod delivers the amount of nicotine as a pack of cigarettes. It is composed of an e-cigarette (battery and temperature control), and a pod of e-liquid which is inserted at the end. The liquid contains nicotine, chemicals and flavorings.
Like other vaping devices, it vaporizes the e-liquid.
3. IQOS by Philip Morris
Pen-shaped, charged like an iPod.
Vaporizes tobacco. It is known as a ‘heat not burn’ smokeless device, heating tobacco but not burning it (at 350C compared to 600C as normal cigarettes do). The company claims this method lowers users’ exposure to carcinogen from burning tobacco.
But, the striking difference came in their decay.
According to the researchers, it was 30-45 minutes before particle concentrations returned to background levels with conventional cigarettes, which caused an increase with every puff. ‘Exhaled e-vapour aerosol particles have a different chemical composition to a cigarette smoke and here we show the physical properties are also significantly different,’ Dr O’Connell said.
‘This data adds to the growing body of evidence that vaping indoors is unlikely to pose an air quality issue.’
