(Spokane, WA)  --  A Spokane woman says she lost a few teeth and suffered other injuries when an e-cigarette exploded in her mouth.  The 45-year-old woman was one of four people across Washington to file lawsuits yesterday against makers of e-cigarettes.  The lawsuits claim the plaintiffs suffered severe injuries when the lithium-ion batteries powering the e-cigarettes exploded.  The other three plaintiffs are from Kelso, Vancouver, and Seattle.
