Electronic cigarettes may appear to be safer than regular cigarettes, but the vapors emitted from e-cigarettes may be even more carcinogenic than tobacco products, according to a letter published in the New England Journal of Medicine.
Researchers with Portland State University tested the vapors from e-cigarettes and found that the liquid aerosol released formaldehyde, a carcinogen used in embalming fluid, cigarettes and disinfectants. The amount of formaldehyde in e-cigarette vapors, however, is even higher than most tobacco-containing cigarettes, researchers claim, giving long-term vaping enthusiasts a lifetime cancer risk 15 times greater than lifetime smokers of regular cigarettes.
E-cigarettes have boomed in popularity in recent years mostly because the products are thought to be safer. The vapor emitted from the products is also odorless, which means people can vape in places where smoking is not allowed.
Many e-cigarettes have voltage settings that allow users to dial up or down the levels of vapors they inhale. Some vapors contain nicotine and other additives. Researchers conducted the study using e-cigarettes on the highest voltage setting, which they said was likely not a level most people used. However, it is one supported by the devices.
The American Vaping Association gave the study no credence, saying researchers were ill informed about e-cigarettes when conducting the study.
What is noteworthy is that vaping is still too new to the market for anyone to grasp what the long-term effects are. The Food and Drug Administration (FDA) is making efforts to regulate the products, and the World Health Organization (WHO) has proposed banning the products indoors the same way regular cigarettes are banned.
