Whether cities such as Lafayette and Moraga can ban medical marijuana dispensaries will be the topic of a high-stakes court hearing.
On Tuesday, the California Supreme Court will hear arguments on whether communities can prohibit these marijuana facilities in light of the 1996 voter-approved law legalizing pot for medicinal uses in California.
As detailed in a San Jose Mercury News story, the hearing stems from a Southern California case where a wellness center sued to overturn Riverside's ban on marijuana dispensaries.
Lafayette and Moraga are two of 21 East Bay cities that have some sort of prohibition in place.
The other Contra Costa County cities with bans are Antioch, Brentwood, Concord, Danville, Hercules, Oakley, Pinole, Pittsburg, Pleasant Hill and San Pablo.
The Alameda County cities with bans are Dublin, Emeryville, Fremont, Hayward, Livermore, Newark, Pleasanton and Union City.
Benicia in Solano County also has a prohibition on marijuana facilities.
On Sunday, police responded to an apparently explosion of hash oil in an Orinda shed where marijuana was being cultivated.
