Corporate giant Walmart announced Friday that it will discontinue all sales of e-cigarettes, also called electronic nicotine delivery systems by the Food and Drug Administration, once its current inventory is sold.

“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 company said in a statement. “We will complete our exit after selling through current inventory.”
