Well John, I wasn't trying to explain in legal terms. But you are right, there is a difference between selling alcohol to a minor than selling cigarettes. Selling cigarettes comes under Class B Misdemeanor (atleast in my state, not sure about the other states). Well in my state the difference between them is the amount of fine and the duration of jail terms, with category A being higher (it's like upto $4000 fine for Category A and about $2000 fine for category B...etc..)

Now the point is (since my friend didn't had issue with the re-entry or was asked any question), are there any laws that states that you are eligible for reentry if you have Misdemeanor B, but then you will have an issue having Misdemeanor A ? If there is , please let me know.
