Walmart will stop selling e-cigarettes in its U.S. locations as the country grapples with a string of vaping-related deaths.

“Given the growing federal, state, and local regulatory complexity and uncertainty regarding e-cigarettes, we plan to discontinue the sale of electronic nicotine delivery products at all Walmart and Sam’s Club U.S. locations,” the retailer said in a statement. “We will complete our exit after selling through current inventory.”

The decision comes after the U.S. Centers for Disease Control and Prevention said this week that 530 people have fallen ill from a mysterious vaping-related lung disease, and that seven people have died. Officials still haven’t determined a cause of the ailment, and there didn’t appear to be one product or substance involved. Cases have been identified in 38 states.

Walmart, which had been up less than 1%, erased gains on the news. Shares of Altria Group, the Marlboro maker that invested in e-cigarette maker Juul Labs last year, briefly pared gains, but bounced back.

Reuters reported news of the decision earlier.

The e-cigarette removal marks at least the third time this year that Walmart Chief Executive Officer Doug McMillon has thrown his company’s considerable heft behind a big issue. In June, he urged Congress to boost the national minimum wage, and he recently promised to stop selling bullets for assault-style weapons, while also requesting that customers not openly carry firearms in its more than 4,700 U.S. stores.

Earlier this year, Walmart stopped selling cigarettes, including electronic ones, to buyers under the age of 21. A spokesperson for the company told Bloomberg that e-cigarettes are a “relatively small category overall” for the retailer.

The recent round of illnesses have been reported most often in patients inhaling products with THC, the key psychoactive ingredient in cannabis. Some were using vaping and e-cigarette devices with both THC and nicotine, while a small number were using nicotine devices alone.

There are signs the number of cases in the U.S. is climbing. On Friday, the New England Journal of Medicine published a letter from researchers at Boston Children’s Hospital who identified 908 confirmed and suspected vaping-related lung injury cases as of Sept. 20. The CDC has been relying on a more conservative count.

Vaping has also been at the center of a growing controversy over what U.S. regulators have described as an epidemic of underage use. Last week, the Trump administration said it would take steps to remove almost all flavored e-cigarette products from the market, pending their approval by the Food and Drug Administration.

Convenience store giant Alimentation Couche-Tard said earlier this week that if policy makers take draconian measures against e-cigarettes, it could end up feeding the black market.

(Michael R. Bloomberg, the founder and majority owner of Bloomberg News parent Bloomberg LP, has campaigned and given money in support of a ban on flavored e-cigarettes and tobacco.)
