Following Walmart, retailers Walgreens and Kroger will also stop selling vaping products at its stores. 

“We have made the decision to stop selling e-cigarette products at our stores nationwide as the CDC, FDA and other health officials continue to examine the issue,” Walgreens said in a statement. “This decision is also reflective of developing regulations in a growing number of states and municipalities.”

Both companies announced the news on Monday, with Kroger releasing a similar statement. 

"Kroger is discontinuing the sale of electronic nicotine delivery products, or e-cigarettes, at all store and fuel center locations due to the mounting questions and increasingly-complex regulatory environment associated with these products. The company will exit this category after selling through its current inventory," the release read. 

The United States Center for Disease Control is currently investigating more than 1000 vaping related illnesses across the country. First Lady Melania Trump also called to end the marketing of these products to children calling them "addictive and dangerous."
