A surgeon general report once cleared the air about smoking. Is it time for one

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.
But that doesn’t mean e-cigarettes are harmless either. And public health experts disagree about exactly how harmful, or helpful, the devices are.
One major obstacle: E-cigarettes haven’t been around long enough for scientists to see if vapers develop problems like lung cancer and heart disease.
