Upper Freehold officials have proposed an ordinance that would block local approval for anything that breaks federal law.
The idea came after Breakwater Alternative Treatment Center announced plans to grow medical marijuana in greenhouses on a farm in the rural Monmouth County community.
New Jersey's law that allows medical marijuana for patients with certain conditions has been slow to launch. The state selected six nonprofit groups to grow and sell the pot. But so far only one has announced full zoning approval for its operations.
Others have run into local opposition.
