The mayor of Los Angeles has signed an ordinance that will close hundreds of medical marijuana shops and banish the rest to industrial areas.
Mayor Antonio Villaraigosa signed the ordinance Wednesday, a week and a day after the city council approved the new law.
The ordinance caps the number of dispensaries at 70 and creates a buffer zone around schools and places of worship.
The city attorney's office says it will be at least 45 days before city officials can enforce the new rules. A letter will be sent to dispensary owners and landlords asking for immediate closure. If they don't comply, the city will likely seek an injunction.
