Following a five-hour debate, the City Council voted 5-2 on Monday to pass a medical marijuana ordinance that limits dispensaries to light industrial zones, which means most of the current pot shops in La Jolla, Ocean Beach, Pacific Beach and downtown will have to close. Nearly 500 people attended the City Council session, which was devoted to the sole topic of a medical marijuana ordinance. The council voted to allow marijuana dispensaries in Mission Valley, Barrio Logan, Southeast San Diego, Otay Mesa and San Ysidro. District 2 City Councilman Todd Gloria made the motion for the ordinance but conceded early in the discussion that the ordinance is “more restrictive that I would care for,” a remark that drew applause. Dispensaries cannot be within 600 feet of schools, parks, libraries, daycare centers or churches, among other restrictions. Dispensaries must have a security system, be open 7 a.m. to 9 p.m. daily, obtain a conditional-use permit and be nonprofit. Patients will be allowed to possess a pound of pot with a state ID card and are allowed to grow 24 marijuana plants. Voting in favor were council President Tony Young and councilmembers Kevin Faulconer, Sherri Lightner and Marti Emerald. David Alvarez was absent.Councilmembers Carl DeMaio and Lorie Zapf voted against the stricter rules.
