Small scale would be enough for immediate personal consumption. She was entering Russia. I'm presuming for her basketball season, so who knows for how long before she's back to the US. So it's not unreasonable to think that she had enough supply to last her for awhile...which would probably be more than the amount that qualifies as "for dealing". Her worst case scenario is she gets charged with possession with intent to distribute, or whatever the Russian equivalent is. And that would be years.
