Study identifies two new cancer-causing chemicals in e-cigarettes liquid
Two more carcinogens have been identified in e-cigarettes liquid.
Concerns have been raised in the past about the possibly toxic emissions that electronic cigarettes produce, from formaldehyde to diacetyl - a chemical connected to lung disease.
But a new study has discovered the presence of propylene oxide and glycidol, two probable carcinogens.
These recent findings, published in Environmental Science and Technology, appears to debunk the myth that vaping is better for your health than smoking.
To break it down: all vapes are made of three basic components: a battery, an atomiser (heating element) and a tank which holds the liquid to be vaopurised.
On top of the atomiser is a small coil which heats up when the e-liquid passes through it and turns it into vapour, releasing the toxic chemicals.
The study, by the Lawrence Berkeley Laboratory in California also shows that the type and temperature of the vapouriser can affect how toxic its emissions are.
As part of their research, the team used two different e-cigarettes and stimulated vaping at different battery settings.
When they tested emissions from an e-cigarette that housed two heating elements, these had a lower concentration of harmful chemicals than the single-coil model.
That's because the same voltage gets distributed evenly with two coils so they can each be heated at a lower temperature, therefore reducing the levels of harmful emissions that are produced.
Researchers hope that the discovery of the link between temperature and toxins could lead to better regulations and products.
The study also found that the age of the e-cigarette could make it more harmful; the longer the e-cigarette had been used, the higher the levels of chemicals is released.
Study co-author Hugo Destaillats said: Regular cigarettes are super unhealthy. E-cigarettes are just unhealthy."
