My Friend's Having a Crisis. Important question.

[Jack of Arcades]

On the 6th, my friend, a 16-year-old girl, was found by her mom with about a dime of weed. She got kicked out/ran away of the house tonight and is staying with a friend.

Given that:

1) She's 16
2) Not a previous offender
3) Lives in Louisiana
4) Was only in possession of a dime and
5) Has not been caught with it by the authorities

What can she expect to happen to her?

Oh, also, her mother found nude pictures of her on her computer. I'm not sure if there's any evidence of transmission to anyone else. If not, is there anything that can be done about that?
