What the science says about the safety of e-cigarettes

Researchers are working hard to determine the cause of more than 500 cases of lung illness affecting e-cigarette users. Eight of those people have died. Even before this outbreak, e-cigarettes divided the medical community. The American Lung Association says bluntly, "e-cigarettes are not safe." But the American Cancer Society says they are "significantly less harmful for adults than smoking regular cigarettes." However, the latest figures show nearly five million children use e-cigarettes. “CBS This Morning” co-host Tony Dokoupil set out to see the science for himself.
