Two more Americans have died from lung illness that were possibly tied to vaping.
Officials are probing whether this “cluster” of lung illnesses are linked to e-cigarette use.
They are investigating links to 450 cases of lung illness around the country, reports Reuters.
The total count of confirmed cases of illness linked to vaping remained at 215, though. 84% of 53 patients with lung illnesses in Illinois and Wisconsin reported using THC in e-cigarettes.
Juul, in which Altria Group Inc has an over 30% stake, is the dominant e-cig maker in the U.S. market.
