The Los Angeles City Council gave final approval Tuesday to an ordinance that will close most medical-marijuana dispensaries in the city.

The ordinance, which passed 9-3, caps the number of dispensaries at 70 and provides guidelines that will push the clinics out of neighborhoods and into industrial areas. More than 130 shops that registered before a 2007 moratorium could also be allowed to stay open if they comply with the rules.

No one is sure how many pot clinics there are in Los Angeles—the best estimate is somewhere between 800 and 1,000—and the ordinance will likely meet resistance from clinic owners.

More than 600 medical-marijuana dispensaries have opened in the city over the past 10 months, despite the moratorium. The shop owners took advantage of a loophole that allowed them to open while awaiting city approval.
