Please quote the Virginia statute that makes being stoned against the law.
Virginia has been in business since the Treaty of London (1604) which gives us 408 years to figure out how to write a statute making being stoned and on public right of way a crime ~ the specific statute was the one about operating motor vehicles ~ there are others that cover other events related to use.
BTW, only stoners would imagine Virginia had neglected to write a law about something.
