Vaping and cancer debate
Portland State University chemistry professor David Peyton had never been attacked with such intensity.
Peyton and a group of other chemists discovered almost five years ago that e-cigarettes could sometimes produce more cancer-causing formaldehyde than regular cigarettes. Formaldehyde is produced by a chemical reaction when a regular cigarette is lit, and finding it at such high levels in e-cigarette vapor, which has been held out as a safer smoking alternative, was a surprise. The study made headlines when the New England Journal of Medicine published it in January 2015.
