"In locales considering extending smoking bans to e-cigarettes, I think that these data weaken the case for more sweeping bans," Fairchild said. "And so this begins to answer the question about why e-cigarettes are considered better: they reduce risks to both the user and to the bystander when compared to
tobacco cigarettes."
I like that they include this stuff in the news story:
"Goniewicz has received funding from a drug company that makes medications to aid smoking cessation. Another study author has received funds from an e-cigarette manufacturer."
... although perhaps more specifics on the latter.
