What would be the total cost of the fines for drug paraphernalia and possession cost total?

me and my brother got busted at a checkpoint in jacksonville, nc right outside camp lejune. we both got a citation for paraphernalia and possession of less then half an ounce of marijuana(like 2 or 3 grams each and each had a bowl). we told the truth and where everything was in the car. we were going to the beach for the weekend with family. we told them we were not habitual users which we are not. we only do it once every few months on a weekend. what is going to happen to us? and how much do you think the total fines and costs will come to?
