Possession of marijuana is still a crime in Virginia. If you're charged with possession of marijuana and this would be your first conviction, you are probably eligible for the First Offender Program. The First Offender program allows the charge to be dismissed after you complete community service and substance abuse counseling.
The bad news is that your drivers license will be suspended in Virginia for 6 months whether you chose to complete the First Offender Program or get convicted of possession of marijuana. Judges in Virginia do not have discretion to waive the 6 month license suspension.
