Walmart has said it will no longer sell e-cigarettes in the US, amid mounting calls to ban the products entirely.
The retailer said its decision was due to “uncertainty” about the rules governing e-cigarettes, which US health authorities have linked to more than 500 cases of lung injury.
US President Donald Trump last week said the US would prohibit sales of all flavoured e-cigarettes.
Two states – New York and Michigan – have already imposed such bans.
On Friday a group of US senators called on health authorities to remove all pod and cartridge-based e-cigarettes from the market until it can be proven the products are safe.
The crackdown has also spread overseas, where this week India said it would ban e-cigarettes.
“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 US locations,” Walmart said.
“We will complete our exit after selling through current inventory.”
