SALT LAKE CITY (AP) Utah health officials say they are investigating 21 cases of a severe lung disease linked to vaping.
The state Department of Health announced the new number Monday, a jump from the five cases in teenagers and young adults reported last week.
The department says the cases stem from the use of a mix of nicotine and marijuana electronic cigarette products.
