5 Significant Downsides of E-Cigarettes
High Temperatures Increase Exposure To Chemicals

As we know now, many opt for electronic cigarettes, thinking they're the healthier choice. The truth is, these e-cigarettes can create many harmful chemicals, including acetaldehyde and formaldehyde. There's a direct correlation between the coil temperature and the chemicals produced. A 2015 study published in the New England Journal of Medicine found that cancer-causing formaldehyde levels from e-cigarettes were fifteen times higher than regular cigarettes. When you increase the voltage of the e-cigarette, you increase your risk of exposure.
Of course, being exposed to harmful chemicals can cause various illnesses and other health complications. The exact potential and specific illness, of course, depends on the chemical in question as well as the quantity.
