What sentence will a person face for mushroom and marijuana possession if there are no prior convictions?

My girlfriend was arrested for possession of mushrooms (5 grams) and marijuana (about 1/8th of an oz.) almost a year ago. I believe the mushroom charge alone is a 2nd degree felony, and I'm not sure about the pot. She is currently 20 and enrolled in a university and has no prior arrests or convictions of any kind. Also, she has hired an attorney to represent her, who seems experienced in these type of cases. My question is this: What is the most probable sentencing she will face? I've scoured the internet and come up empty-handed, so any insight will be greatly appreciated. Thank you.
