SAN JOSE — With just weeks to go before a December deadline for compliance, medical marijuana providers are still balking at some of San Jose’s rules and city officials are offering to ease them.

Nineteen pot providers have been seeking to meet San Jose’s regulatory requirements by Dec. 18. The rules, adopted in June 2014, restrict pot stores to select industrial and commercial areas away from schools and parks and impose a host of security, tax payment and other requirements. Dispensaries that fail to meet the requirements by the deadline face closure.

But one rule in particular requiring pot stores to demonstrate that their marijuana is cultivated locally and not from collectives around the state remains a sticking point. City officials plan to ask the City Council to ease the rules Tuesday, allowing another five months for shops to sell through products obtained from “third-party” vendors and letting San Jose pot clubs buy and sell to one another.

Angelique Gaeta, an assistant to the city manager who oversees the medical pot program, wrote in a staff report that the proposed changes will “provide those medical marijuana collectives that are working their way towards registration with greater flexibility and opportunity for success.”

But Mayor Sam Liccardo says that that proposal needs more study. And marijuana providers say the olive branch doesn’t go far enough and are planning a City Hall rally Tuesday to drum up support for a ballot measure that would let city voters consider looser rules in 2016.

“I don’t care what the hell is motivating the mayor,” said Oakland-based attorney James Anthony, who helped organize Sensible San Jose, a political committee that crafted a June 2016 ballot measure to replace the city ordinance with more relaxed regulations. “We are going to rouse the troops and generate public awareness. … It’s time to give up on the city and go to the voters.”

The current rules require San Jose medical pot collectives to cultivate their own weed either on-site or at a single off-site location within Santa Clara County or neighboring counties. Gaeta said this “vertical integration” model helps track the weed from “seed to sale” to prevent diversion to kids, black-market sales and find the source of bad batches of marijuana.

But pot clubs say that rule makes it hard to keep up with demand since it takes months to harvest the weed. They add that the rule also makes it difficult for stores to offer “edibles,” such as ice cream and cookies, that come from collectives around the state and are preferred by patients who don’t want to smoke the marijuana.

City officials say the proposed changes would ease the burden of meeting demand under the new model. In addition to allowing the shops to transfer pot among themselves and to dispense weed they have on hand from third-party vendors for five months after the Dec. 18 deadline, other suggested revisions include:

Allow collectives to manufacture marijuana at their dispensaries or an off-site location with more space.

Allow the transportation of marijuana from one site to another from 6 a.m. to midnight.

Decrease the length of time surveillance video must be stored from 90 days to 30 days to reduce dispensary costs.

Require collective owners and employees to wear badges issued by police to show they’ve been fingerprinted and had a criminal-background check.
