In Virginia, it is unlawful for any person to knowingly or intentionally possess marijuana. The only way possession is legal is if the marijuana was obtained directly from, or pursuant to, a valid prescription or order of a professional practitioner.
A first offense for possession of marijuana is an unclassified misdemeanor which carries up to 30 days confinement in jail and a fine up to $500, either or both. A first offender will likely qualify for a diversion program whereby, upon compliance with all terms of probation, including community service, drug education and treatment, loss of driving privileges and general good behavior, the charge will be dismissed.
A second or subsequent offense is a Class 1 misdemeanor and carries up to 12 months incarceration and a fine up to $2,500, either or both. All marijuana convictions require a six month loss of driving privileges (restricted privileges may be granted by the court).
