Within the next 90 days, pharmacy chain Rite Aid will raise the minimum age to buy tobacco products to 21, according to CNBC.
Rival drugstore chain Walgreens announced April 23 that it would require tobacco buyers to be 21 years or older on Sept. 1.
"Raising the age for purchasing tobacco products is an important step in our efforts to ensure that these products do not fall into the hands of children and teens," Rite Aid COO Bryan Everett told CNBC.
A dozen states already have raised the minimum buying age for tobacco products.
Rite Aid said it would stop selling e-cigarettes at its stores earlier this month.
