PUBLIC HEALTH Tests: Formaldehyde risk in some e-cigarette vapor Portland chemist among researchers who authored New England Journal of Medicine article Comment By Marilynn Marchione The Associated Press MailTribune.com By Marilynn Marchione The Associated Press Posted Jan. 21, 2015 @ 4:26 pm By Marilynn Marchione The Associated Press Posted Jan. 21, 2015 @ 4:26 pm » Social News Using certain electronic cigarettes at high temperature settings could potentially release more formaldehyde, a cancer-causing chemical, than smoking traditional cigarettes does, new lab tests suggest. The research does not prove a health risk — it involved limited testing on just one brand of e-cigarettes and was done in test tubes, not people. It also does not mean e-cigarettes are better or worse than regular ones; tobacco smoke contains dozens of things that can cause cancer. But it does highlight how little is known about the safety of e-cigarettes — battery-powered devices that heat liquid to deliver nicotine in a vapor rather than from burning tobacco. "It's a potential red flag," one independent expert — Stephen Hecht, a chemist and tobacco researcher at the University of Minnesota — said of the study. "Under some conditions, e-cigarettes might be generating more formaldehyde than you'd want to be exposed to. But I don't think we know enough yet. There's a huge variety in the makeup of these cigarettes and how they are used." The study was published Wednesday as a letter in the New England Journal of Medicine. The journal said it had been reviewed by experts in the field. Formaldehyde is found in many things — certain building materials, disinfectants and embalming fluid. An earlier study found e-cigarettes generated less formaldehyde than regular cigarettes do, but that study looked at just the gas portion of the vapor. The new one looked at the liquid particles in the vapor, like the spray from an aerosol can. Some tank system e-cigarettes let users turn up the voltage to increase the heat and the amount of liquid, which contains the nicotine and flavorings, in the vapor. David Peyton, a chemist at Portland State University, and colleagues tested one brand with two voltage settings. They used a syringe to collect vapor from 10 samples, each one representing several puffs, at both voltage levels. They measured formaldehyde hemiacetal — a compound created during the vaping process that under certain conditions can release formaldehyde — in the liquid portion of the vapor. At low voltage the chemical was not detected. But at the high voltage setting, levels of that compound were five to 15 times greater than the amount of formaldehyde users would get from traditional cigarettes. Virtually all e-cigarettes use similar materials in the heated liquid, so the finding on formaldehyde "is not brand-dependent," said Peyton, who plans more extensive tests. However, Gregory Conley, a lawyer with the American Vaping Association, an advocacy group for e-cigarettes, criticized the study methods. "They use the device in a manner that no one does," he said. Using the high voltage for as long as the researchers mimicked in the study "creates a burning, acrid taste" called a "dry puff" that would cause users to adjust the e-cigarette, Conley said. What the researchers did is like leaving a steak on a grill all day — many cancer-causing substances might be formed but no one would eat such charred meat, he said. Eric Jacobs, a biologist at the American Cancer Society, said a biochemist at the society looked at the work and "was reasonably convinced" that the chemical researchers measured would break down into formaldehyde in the user's lungs. "No one should conclude from this that e-cigarettes used at high voltage are worse than combustible tobacco cigarettes," because of all the other toxins in tobacco smoke, Jacobs said. The society's advocacy affiliate, the Cancer Action Network, said the research "should raise serious concerns" about the lack of regulation of e-cigarettes, and urged the Food and Drug Administration to quickly finalize the proposal announced last spring to do so. ___ By Marilynn Marchione The Associated Press MailTribune.com By Marilynn Marchione The Associated Press Posted Jan. 21, 2015 @ 4:26 pm » Comment or view comments Reader Reaction » STAY INFORMED Email NewsLetter Sign Up Today Sign up for our newsletter and have the top headlines from your community delivered right to your inbox. calendar Connect with MailTribune.com Facebook Twitter RSS Back to top Reader Services Reader Services Home Subscriptions Subscriber controls Contact us Submissions Photos Events Letters to the editor Corrections Announcements Obituaries Story ideas Since you asked Alerts Email Alerts RSS Feeds Text Alerts Advertise Media Kit Home Products and services Ad rates Advertising contacts Mail Tribune Daily Tidings The Nickel Shop Our Valley Blogs Stay Informed Email newsletter Sign Up Today Sign up for our newsletter and have the top headlines from your community delivered right to your inbox.
