Study Shows High Formaldehyde Risk From E-Cigsby Diane Domina Content Production Editor
Researchers from Portland State University in Oregon, who published a study three years ago about formaldehyde in electronic cigarettes, have updated their findings to indicate levels of the highly toxic substance in e-cig vapor are even higher than previously reported.
In the 2015 study, the researchers discovered vapor from electronic cigarettes contain a new form of formaldehyde – a known cancer-causing agent (carcinogen) – at a level 5 to 15 times higher than regular cigarettes when vaping devices are used at their highest heat settings. This new form of formaldehyde binds to particles in the vapor, allowing them to be inhaled more deeply into the lungs.
In their recent study, the researchers discovered formaldehyde – in both forms – is present at high levels even when vaping devices and electronic cigarettes are used at lower, more common heat settings.
