Dr. Brandon Larsen of Mayo Clinic Arizona says he believes toxic fumes are causing at least some of the illnesses. The study was published Wednesday in the New England Journal of Medicine.
Incomplete lab testing by FDA continues to find THC and vitamin E acetate, a thickener, in some of the liquids tested, but Schuchat cautioned: “There may be a lot of different nasty things in e-cigarettes and vaping products and they may cause different harms in the lung.”
