Can you use a matricula consular as proof of age to purchase cigarettes?

What you are essentially asking is whether the guy behind the counter in the deli will accept your proof. This is up to the discretion of the guy. Many places do not card anyway. The big question is: Are you and do you look old enough to buy cigarettes? If you're 43 years old, they probably will accept it. If you're 14, then you might run into trouble.
