US vaping-linked death toll hits 26

Twenty-six people have died from illnesses associated with e-cigarette use since March, US health authorities said Thursday, while some 1,300 have suffered lung injuries linked to vaping. Officials have yet to identify the cause for the outbreak, which dates back to late March, and are pursuing multiple lines of investigation. More than three-quarters of those sickened used tetrahydrocannabinol (THC), the primary psychoactive substance of marijuana, with or without nicotine products.
