If you have a juvenile record you can get it expunged in 6 months or 5 years in more serious cases such as drug dealing.
A recent case had a 24 year old man who, at 17, had been convicted of selling Ecstasy in a school. He had been in no further trouble, finished school, and had a good job. The Court, over the objections of the prosecutor, allowed the expumgement.
