i live in georgia as well.
dont know where you can find them in writing, i looked around the
http://www.ga.gov website though, and it (has a shitload of info btw) seemed like it might have something useful if you dig around it for a little while. not 100% on that though. a while back though i had a dui (for weed

) and was gifted with this phone number as part of an "operation 21" class, which needless to say wasn't even relevant to me, but this number is holy. you can call them and leave a message about ANY GA LAW and they will get back to you either same day or a day or so later.the answering machine doesn't specifically note it, but i have used it many times before regarding marijuana laws and know it to be true firsthand. the number is 678 947 1521. feel free to call them as often as you want, as they have to return your messages. OH and dont forget to leave a number for them to contact you on.
from my experience, things you'll need to do beforehand... COMMUNITY SERVICE! i can't stress this enough. ga court people, for whatever reason, highly regard the effort of doing the right thing before court. get as many hours as you possibly can and aim for around 40-80. dont take that amount lightly either, it can, and probably WILL help you get a reduced sentence. if you ARE stuck with the felony charge in court, then you'll have to do community service anyways, and generally alot more than that (due to it being felony, i've heard horror stories of up to 250 hours in extreme cases), so it's best to get it out of the way asap, cause, the best part is, they're rollover minutes. so even if you get charged, after court you wont have to start over. **the outpatient rehab beforehand is a fantastic idea too
long story short, go to goodwill, must ministries, or any other non profit. (american cancer society will let you do community service through them and they let you sit in an office chair all day and fill envelopes for their mailing list) just call around. any non profit organization will do, try to find the closest to you.
other than that, start saving your money, your going to need every penny. my sympathies go out to you, im sorry you have to live in the bible belt as well. (you dont happen to live in cobb county do you? you don't have to answer that publicly..) good luck
