Level of e-cigarette power contributes to hazard

The higher the power of an e-cigarette, the higher the concentrations of potentially hazardous substances the device produces, including acetaldehyde, acrolein, and formaldehyde.

Those are among the findings presented at an international conference of the American Thoracic Society by lead study author Dr. Daniel Sullivan, an internal medicine resident at the University of Texas Southwestern Medical Center. During his previous training at the University of Alabama, Birmingham, Dr. Sullivan and his associates used a variety of methods including liquid chromatography–mass spectrometry and enzyme-linked immunosorbent assay (ELISA) to study components and nicotine formulations typical of e-cigarette users.

Under some test conditions, formaldehyde levels were comparable to those seen in traditional tobacco cigarettes.

“We set out to find the essentilal composition of e-cigarrets  that affect the levels of toxic compounds that they produce.  We specifically looked at the power levels that you can experience with these devices. We looked at the ratios of vegitable glycerin glycerol and propline glycol and we lookd at the effect it has on pulmonary inflammation. We found that power is what seems to matter for increasing levels of toxic compounds. All toxin levels increased as the power level of the device increased. The level of power comes from the resistance of the individual coils  as well as the voltage the users can tune on their devices. That was one finding. The other finding was that as the level of glycerol in your ecigarette liquid increased the level of toxins increased as well. From using e-cigarrettes we were exposing an enzyme that became unresponsive.” See video below for more
