What is the difference in punishment for this kind of DUI?

Got a DUI a few weeks back. I blew a .083 which is only .03 over the limit. However they were under the impression that I was using marijuana, I had not been that day. They gave me a drug test and I will probably fail because i did smoke like four days straight a few days before. I know if I fail I will not be eligible for a work permit to drive on but do you know any extra consequences I may be facing? Thanks!
Ok first answer I know for a fact just for a regular DUI here in the state of GA you lose your license for 4 months but thank you for answering. I am expecting it to be worse than that but hey if that is right I would be very happy!
