E-cigarettes contain up to 10 times the carcinogens of regular tobacco: Japan research | The Japan Times

E-cigarettes contain up to 10 times the level of cancer-causing agents as regular tobacco, Japanese scientists said Thursday, the latest blow to an invention once heralded as less harmful than smoking.

The electronic devices — increasingly popular around the world, particularly among young people — function by heating flavored liquid, which often contains nicotine, into a vapor that is inhaled, much like traditional cigarettes but without the smoke.
