CDC investigating lung problems, possibly linked to vaping
There are new concerns about the dangers of vaping.
The U.S. Centers for Disease Control is looking into lung problems they think may be linked to e-cigarettes.
This is mostly in teens and young adults.
Officials say they've had reports of coughing, shortness of breath and fatigue in 14 states.
The CDC says it doesn't look like some kind of virus or bacteria is the problem but they can't say for sure yet whether vaping is to blame.
There have been 94 reported cases of lung issues since the end of June.
