The pending arrival of legalized marijuana has left many California cities unprepared to deal with the potential impacts of commercialized cannabis. And the City of Lathrop is asking for a bit more time to get a handle on the laws and regulations governing what is expected to become a burgeoning industry. Tonight city staff is recommending that the Lathrop City Council approve an urgency ordinance that would place a 45-day moratorium on the opening of commercial cannabis businesses within the Lathrop city limits.
