【英语时差8,16】电子烟真的安全吗？（下）

Many health researchers are dubious¹, though. A 2009 FDA study of e cigarettes found trace amounts of diethylene glycol a solvent² linked to kidney failure. And some experts worry that because e cigarettes are marketed as being clean and safe, they may attract young non smokers³ and lead them down the road to nicotine⁴ addiction⁵. To be fair, the point is not that e cigarettes are necessarily a health hazard. Maybe they are, and maybe they’re not. We simply don’t know. Which is why many health experts are calling for e cigarettes to be regulated like drugs and required to meet federal safety standards. Until that happens, trusting that e cigarettes are harmless means relying on the word of the companies that make and sell them.
