NEW YORK (AP) — Walmart is getting out of the vaping business.

The nation’s largest retailer said Friday that it will stop selling electronic cigarettes at its namesake stores and Sam’s Clubs when it sells out its current inventory.

The nation’s largest retailer said the move is due to “growing federal, state and local regulatory complexity” regarding vaping products. It also comes after several hundred people have mysteriously fallen ill after vaping, and eight have died.
