E-cigarettes have become increasingly popular as a smoke-free alternative to conventional tobacco cigarettes, but the health effects of “vaping” on humans have been debated in the scientific and tobacco manufacturing communities. While aldehydes–chemicals like formaldehyde that are known to cause cancer in humans–have been identified in e-cigarette emissions by numerous studies, there has been little agreement about whether such toxins exist in large enough quantities to be harmful to users.
Now, a recently published pilot study by a team of researchers from the Desert Research Institute (DRI) and the University of Nevada, Reno shows that significant amounts of cancer-causing chemicals such as formaldehyde are absorbed by the respiratory tract during a typical vaping session, underscoring the potential health risks posed by vaping.
“Until now, the only research on the respiratory uptake of aldehydes during smoking has been done on conventional cigarette users,” said Vera Samburova, Ph.D., associate research professor in DRI’s Division of Atmospheric Sciences and lead author of the study. “Little is known about this process for e-cigarette use, and understanding the unique risks vaping poses
