NEW YORK — Sixty years ago, the U.S. surgeon general released a report that settled a longstanding public debate about the dangers of cigarettes and led to huge changes in smoking in America. Today, some public health experts say a similar report could help clear the air about vaping. Many U.S. adults believe nicotine vaping is as harmful as — or more dangerous than — cigarette smoking. That’s wrong. The U.S. Food and Drug Administration and most scientists agree that, based on available evidence, electronic cigarettes are far less dangerous than traditional cigarettes.
