LOS ANGELES — Ready or not, California kicks off recreational marijuana sales on Jan. 1. And, mostly, it's not.
Los Angeles and San Francisco are among many cities still struggling to fashion local rules for pot shops and growers. Without the regulations, there could be limited options in many places for consumers eager to ring in the new year with a legal pot purchase.
"The bulk of folks probably are not going to be ready Jan. 1," conceded Cara Martinson of the California State Association of Counties.
In general, California will treat cannabis like alcohol, allowing people 21 and older to legally possess up to an ounce and grow six marijuana plants at home.
Come January, the newly legalized recreational sales will be merged with the state's two-decade-old medical marijuana market, which is also coming under much stronger regulation.
But big gaps loom in the system intended to move cannabis from the field to distribution centers, then to testing labs and eventually retail shops.
The state intends to issue only temporary licenses starting in January, and it has yet to release its plan to govern the estimated $7 billion marketplace, the nation's largest legal pot economy.
If businesses aren't licensed and operating in the legal market, governments aren't collecting their slice of revenue from sales. The state alone estimates it could see as much as $1 billion roll in within several years.
Operators have complained about what they see as potential conflicts in various laws and rules, or seemingly contradictory plans.
The state expects businesses that receive licenses will only work with others that hold them. But that has alarmed operators who wonder what will happen if their supplier, for instance, decides not to join the new legal market.
Others say it's not clear what could happen in cities that don't enact pot laws, which they warn could open a loophole for businesses to set up shop. Some communities have banned recreational sales completely.
Most banks continue to refuse to do business with marijuana operators - pot remains illegal under federal law - and there are also problems obtaining insurance.
With recreational legalization fast approaching, "we don't have enough of anything," lamented Hezekiah Allen, executive director of the California Growers Association, a marijuana industry group.
The route to legalization began last year when voters approved Proposition 64, which opened the way for recreational pot sales to adults in the nation's most populous state.
Unlike the state, cities and counties face no deadline to act. However, the concern is that confusion and a patchwork of local rules could discourage operators from entering the legal economy, feeding a black market that could undercut the legitimate one.
Local regulation is a foundation block of the emerging pot economy: A grower or retailer needs a local permit first, which is a steppingstone to obtaining a state license to operate.
But those rules remain in limbo in many places.
