Though Californians voted to legalize adult use marijuana in 2016, it remains largely unavailable in some of the biggest cities in the state.

Out of the 482 cities in California, 174 of them allow some form of licensed cannabis business, says Hirsh Jain of Ananda Strategy.

Many of those cities allow only non-retail cannabis operations, such as manufacturing or distribution, “and so are arguably missing the most important part of the legal supply chain,” Jain said.

That’s because Proposition 64, the ballot initiative that legalized adult-use marijuana in the state, contained a provision that gave local jurisdictions the power to decide for themselves whether to allow retail cannabis activity in their boundaries.

Of the 10 largest cities in the state where there are no marijuana dispensaries, two are in the San Joaquin Valley, one is in the Bay Area, and the rest are located in Southern California, according to the website WeedMaps. Together, they account for more than 2.8 million people without immediate access to cannabis retail, outside of delivery.

Even cannabis delivery could be subject to local jurisdiction requirements, said Moorea Warren of the California Department of Cannabis Control, though a state license authorizes a cannabis delivery company to deliver to any jurisdiction in the state. [Read more at The Sacramento Bee]
