Expungement in GA for misdemeanor allowed? Criminal Records, Expungement

I pleaded guilty 14 years ago for minor possession of marijuana in Georgia. At the time I did not use an attorney (stupid I know) and was not aware of the first offenders act. Had I known this existed I would have entered this program.

Is it possible to have this expunged from my record?

I plan to apply to take the CPA exam in the near future and I do not want this to cause problems passing the "moral turpitude" question on the application.

I will be seeking legal counsel but thought I would also ask your opinions here.

Thank you for the help.
