(NPR) — Just In: Walmart said they will stop selling e-cigarettes, after selling the current inventory now available at stores, citing regulatory concerns. This comes a day after the CDC warned of 530 cases of lung injuries associated with vaping.
With more than 500 cases of acute vaping illness reported, doctors worry about the long-term effects on patients' lungs. And federal agencies still don't know what's behind the outbreak.
The Centers for Disease Control and Prevention announced Thursday that there are now 530 confirmed or probable cases of lung injury associated with vaping, a jump from 380 cases reported last week. Seven people have died.
The CDC has ramped up its investigation, activating its Emergency Operations Center this week in an effort to nail down the cause of the illnesses, which remains unclear. In addition, the Food and Drug Administration has enlisted the help of its office of criminal investigations, the law enforcement arm of FDA.
