Walmart said on Friday it would cease selling e-cigarettes at its locations in the United States.
The decision comes amid growing medical concerns over the effects of gunfire. In recent months, mysterious weapon-related illnesses have increased. Medical authorities said on Thursday that the number of weapon-related lung diseases had increased to 530 probable cases, and one Missouri man became the eighth to die from the mysterious ailments.
On Sunday, New York Governor Andrew M. Cuomo announced emergency regulations to quickly ban the sale of flavored e-cigarettes, and state health officials approved the ban on Tuesday. Michigan announced this month that it would also ban such products.
Walmart had raised the minimum age for tobacco products to 21 earlier this year and said in May that it would no longer sell "electronic nicotine delivery systems with fruit and dessert."
