LUMBERTON, Texas — Monday was the first day Walmart customers nationwide experienced a new policy.

The minimum age for buying tobacco products has been raised to 21.

Walmart said the policy is part of an effort to keep tobacco out of the hands of minors.

Walmart's new policy gives Texans a taste of what's to come.

Only those 21 and older will be able to purchase tobacco products in Texas starting in September.

It comes with a military exemption, meaning all military members over the age of 18 will still be able to purchase tobacco.  

Texas will become the 14th state to raise the tobacco purchase age to 21 and just the third to incorporate a military exemption.

Walmart's decision has drawn both criticism and praise. 

Bill Frazier of Kountze disagrees with the decision.  

"If you're going to send people off to war, why can't they buy cigarettes? I understand the reasoning behind it, but I don't agree with it," Frazier said. 

The new policy includes e-cigarettes.

"I just wish they would think things through and do it differently," Frazier said.

The policy is now the same for Sam's Clubs nationwide, which Walmart owns.

In a couple months everyone in Texas will experience this change.

Governor Greg Abbott signed into law a bill that prohibits the sale of cigarettes and other tobacco products to anyone under the age of 21.

For Renee Jayroe, she's glad they're making the change. 

"Smoke bothers me, so anything that means less smoke I'm for it, I wish they'd outlaw smoking period," Jayroe said.
