The New England Journal of Medicine published a study on Wednesday, January 21 stating that e-cigarettes produce vapor with exceedingly high concentrations of formaldehyde, a carcinogen.  Proponents of e-cigarettes quickly dismissed these findings; Gregory Conley of the American Vaping Association asserts that the study was conducted under unrealistic conditions and does not reflect the actual vapor produced when a real person is using an e-cigarette.  The premise of e-cigarettes is that they heat a nicotine liquid to create a vapor that users inhale instead of smoke.  Some research purports to show that the level of toxins in the vapor is lower than in traditional smoke; however, medical professionals and researchers disagree and set out to find out more about the new e-cigarettes and the potential risks they pose to users.  David Peyton, a chemistry professor at Portland State University, helped conduct the new research and found that when the e-cigarette is set at high levels, the vapor drawn into the users lungs contains levels of formaldehyde far exceeding those in regular cigarettes.  While the e-cigarettes can be used at varying levels and may not produce the dangerous substance at low levels, Peyton believes that many people use the high settings and unknowingly expose themselves to dangerous chemicals.  The FDA is still considering the type of controls it will place on e-cigarettes.
