I was convicted in 1997 of possession with intent to deliver marajuana in Mairetta Georgia. Wanted to know if it can be expunge.

Usually it is not possible to get a conviction expunged from your record.  Once you have a felony conviction it generally stays a conviction on your criminal history.  When someone is banned from the state, or a county, that is only in effect while you are under sentence of that particular charge.  Once your sentence expires there is no means of enforcing that ban since you are not under sentence, or control, of that court.
