With a week left to gather signatures for two November referendums, local medical marijuana advocates attracted hundreds of San Jose residents Thursday with the offer of free evaluations. Naturally, a line stretched down the street.

New rules for medical marijuana collectives in San Jose go into effect July 18, but the fight between cannabis advocates and City Hall continues.

Two years after the marijuana industry overturned local regulations on collectives, city officials aim to give it another shot.

Under a regulatory proposal making its way through City Hall, all but a handful of local pot clubs would have to shutter or relocate.

A group of dispensary owners filed an initiative to bring a full set of marijuana regulations to San Jose voters this fall. The “Medical Marijuana Regulation for San Jose Act of 2014” aims to set a minimum of 50 pot clubs. It also asks the city to form a cannabis commission similar to the advisory boards it has for libraries and parks, land use and transportation, among other interests.
