Medical marijuana advocates, failing in a petition drive to force a ballot measure to overturn a Sacramento County dispensary ban, appealed Tuesday to supervisors to reconsider their refusal to permit cannabis outlets.

Twenty-five people, including former dispensary operators and others who use medical marijuana, lined up in the county boardroom to present more than 30,000 signatures calling on the Board of Supervisors to license at least 22 cannabis stores – or one for every 25,000 county residents.

The advocates got a thank you from the board for being respectful. And they politely threatened a lawsuit.
