Kroger said Monday it will halt the sale of e-cigarettes, citing "mounting questions" over the products' health and regulatory implications.

The company issued a brief 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."

Kroger's decision comes less than three weeks after a similar move by Walmart to ban the products.

"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," Walmart said.

Several companies have moved to distance themselves from vaping amid an investigation by Centers for Disease Control and Prevention into more than 805 cases of a lung disease associated with the products.

Media giants Viacom, CBS and WarnerMedia all revealed last month that they would stop running advertisements for e-cigarettes.
