The Grand Junction City Council has passed a measure to close medical marijuana businesses in the city.

The council voted 6 to 1 to pass the ordinance Monday night. Mayor Teresa Coons was the only member to vote against it.

The ordinance requires that all dispensaries and other pot businesses shut their doors by Jan. 1, 2011.

However, the Grand Junction Sentinel reports that dispensaries are prepared to fight the measure. They plan to petition the council to reconsider and they could also push for the issue to be put to voters or challenge the ban in court.
