CHICAGO - U.S. health officials said on Thursday there are now 530 confirmed and probable cases and seven deaths from severe lung-related illnesses tied to vaping, and there are no signs that the outbreak is easing.
That's up from 380 cases reported a week ago. Three-fourths of the cases are male, and two-thirds are between the ages of 18 and 34.
The U.S. Food and Drug Administration is now investigating more than 150 products and substances and said it has activated its criminal investigations arm to explore the supply chain of vaping products and identify the cause of the outbreak. No individual vapers will be targeted, Mitch Zeller, director of the FDA's Center for Tobacco Products.
Zeller said no single substance or compound, including THC or Vitamin E acetate, has been linked to all of the cases so far.
Seven people have died from vaping-related illness, the Centers for Disease Control and Prevention (CDC) said. The deaths were reported in California (2), Illinois, Indiana, Kansas, Minnesota, and Oregon.
