The health impacts of electronic cigarettes have been a topic of debate for quite some time. However, a recent laboratory study has revealed a new concern, indicating that these devices pose a significant risk in terms of hygiene as well. According to the research, the mouthpiece of electronic cigarettes harbors a multitude of microbes, far exceeding the average amount found on a toilet seat.
In a study jointly conducted by the independent laboratory BioLabTests and an online nicotine retailer, a popular model of electronic cigarette was put to the test. Researchers swabbed the mouthpiece of the device with special cotton swabs immediately after it was first opened, and then again after 24, 48, 72 hours, one week, and two weeks of use, to examine the density of microbes.
The most striking finding was the rapid increase in microbes between the second and third days of use. During this period, it was observed that colonies of bacteria and fungi multiplied by hundreds of times. Measurements taken on the third day revealed approximately 150,000 colony-forming units (CFUs) on the mouthpiece.
To put this into perspective, an average public toilet seat harbors about 6.5 CFUs per square centimeter. This implies that the electronic cigarette is 3,000 times dirtier.
Microbiologist Reynold Mpofu from BioLabTests, who evaluated the research, emphasizes that the mouthpiece is by far the dirtiest part of the device. Mpofu, reminding us that even the human mouth hosts approximately 700 different types of bacteria, points out that these microorganisms have the opportunity to multiply rapidly in uncleaned mouthpieces.
Moreover, it's not just the mouthpiece; the body of the device also harbors a significant amount of germs. Tests revealed the presence of microorganisms such as Bacillus, Staphylococcus, Enterococcus, and even E. coli, all of which can pose a threat to human health.
The growth of fungal colonies poses a greater risk due to the spores that could potentially be transported to the lungs. Particularly, the risk of infection multiplies for those who share the device.
According to researchers, electronic cigarettes have become a habit that needs to be reconsidered not only due to the chemicals they contain, but also due to the hygiene risks they carry.
