California dropped its biggest enforcement grant yet on Thursday, June 25, 2026, when Governor Gavin Newsom announced $227 million in Proposition 64 grant funding for local communities. It is the fourth cohort of awards under the state's Proposition 64 Public Health and Safety Grant Program, and the largest by a wide margin.
With this round, total Proposition 64 funding through the program now tops $350 million. The first three cohorts combined came to roughly $123 million, so Cohort 4 alone is bigger than everything that came before it. That jump says a lot about how deep, how stubborn and how profitable the underground economy has remained in California.
"The voters created a legal, regulated cannabis market, and we have a responsibility to make sure it works as intended," Newsom said in the announcement. The money is aimed squarely at the gap between that intention and what is actually happening on the ground.
A problem that has only grown bigger
Let's set the scene honestly, because the numbers demand it. California voters passed Proposition 64 on November 8, 2016, by a 57% to 43% margin, and licensed adult-use sales began on January 1, 2018. Nearly a decade later, the unlicensed market is still the bigger one.
California NORML puts it bluntly: by its count, 6 out of every 10 cannabis sales in the state come from the illicit, untaxed market. More than half of the cannabis moving through California skips the licensed system entirely.
That's not a footnote. That's the headline the industry has been living with since day one, and it's the central reason Cohort 4 feels both monumental and, to the people in the trenches, long overdue.
Licensed cultivators, manufacturers and retailers have spent heavily on permits, compliance infrastructure, testing and track-and-trace. They are competing against a supply chain that carries none of those costs and, for years, faced relatively little risk of meaningful consequence. The legal market was built to replace that supply chain. So far, it hasn't.
The funding mechanism itself is worth understanding. Proposition 64 created a state excise tax on cannabis sales, and a designated share of that tax revenue funds grants to local governments to deal with the effects of legalization. The legal market pays taxes; those taxes fund local enforcement and prevention; the illegal market shrinks, and the legal one grows. In theory.
Where the $227 million actually goes
The Board of State and Community Corrections (BSCC) administers the grant program, and the money isn't a blank check to any single agency. It goes to cities and counties, which apply for funding across four focus areas:
- Public safety and enforcement
- Youth prevention and intervention
- Public health
- Environmental impacts
The enforcement lane is the one that gets the headlines. Local agencies use it to go after unpermitted grows and unlicensed storefronts, and to build the staffing and data systems that make enforcement stick. The illegal cannabis economy doesn't respect county borders, and a grow in the hills can feed an unlicensed shop hundreds of miles away.
The environmental lane matters just as much. Unlicensed cultivation at scale has been tied to illegal water diversion, pesticide use and habitat damage, particularly in rural counties and on public land. Grant-funded inspections are how many counties document and act on those violations.
According to the announcement, the BSCC initially had $125 million available for this cycle. The board then leveraged anticipated Fiscal Year 2026–27 funding so that every eligible applicant could be fully funded. That decision is what pushed the cohort to $227 million.
Eligibility also widened this time. Under updated criteria in the 2025 Budget Act, jurisdictions qualify if they allow retail cannabis sales, or, for communities with fewer than 10,000 residents, if they allow cannabis delivery. The change rewards cities and counties that have opened the door to the licensed market rather than banning it outright.
What earlier grants delivered
The state pointed to results from previous cohorts to make the case for scaling up. Across prior grantees, the program says it has eradicated nearly one million illegal cannabis plants and seized 295 illegal firearms.
A few counties were singled out. Humboldt County removed more than 267,000 unpermitted cannabis plants, identified 188 environmental violations and seized illegal firearms. San Francisco created new enforcement positions and built a mobile data tracking system. Santa Barbara County increased compliance inspections and doubled its illicit cannabis enforcement actions.
BSCC Board Chair Linda Penner framed the grants as a way to give communities the capacity to handle cannabis issues that look different from one place to the next. A Humboldt watershed problem and a San Francisco storefront problem need different tools, and the program is built to let local governments pick them.
The escalating investment, cohort by cohort
To appreciate what $227 million means, look at the arc. Three earlier cohorts added up to roughly $123 million. Cohort 4 nearly doubles the program's lifetime total in a single round, lifting it past $350 million.
The trajectory is impossible to ignore. California is not nudging its approach; it is scaling it up. Whether that scale is enough to move a market where Cal NORML estimates 60% of sales remain unlicensed is the question the industry will be watching as these funds get deployed and grantees report back.
That $350 million is both impressive and humbling. Impressive because it is real money aimed at protecting the legal market. Humbling because the unlicensed market, by the most widely cited estimate, still outsells the legal one, and it keeps doing so with lower prices and zero compliance overhead.
What this means for licensed operators
If you're a licensed cannabis retailer, cultivator or manufacturer in California, you've been operating in a uniquely brutal competitive environment. The brands that did everything right, from licensing and audits to lab testing and paying taxes, are up against sellers who skip every one of those costs.
That's not a slight pricing disadvantage. It's a structural one. Shoppers already hunt for deals at licensed stores, which is why guides like our rundown on how to save money at California dispensaries get read. The unlicensed shop down the street doesn't carry the same tax bill.
The licensed industry has been vocal in calling for exactly what Cohort 4 represents: real enforcement resources. For operators who made the painful move into compliance, the illegal market isn't an abstraction. It's the competitor down the street.
Newsom's office framed the announcement as making sure the legal market "works as intended." Whether enforcement dollars alone can close the price gap is a more complicated question that involves tax policy, licensing and market access. Enforcement is a necessary condition for the legal market's long-term health. It isn't a sufficient one.
Operators tracking these policy shifts will find them on the agenda at the industry's big trade gatherings. Our look at what MJBizCon 2026 is for and the Hall of Flowers 2026 B2B calendar cover where those conversations happen.
The road ahead: enforcement without reform is a half-measure
Nobody in the industry seriously believes $227 million in grant funding, welcome as it is, will solve California's illicit cannabis problem on its own.
The structural issues remain. A tax burden prices legal product above the street. The licensing process is slow and expensive. The banking system still treats cannabis businesses like contraband. All of it feeds the conditions that keep the illegal market durable and appealing to producers and consumers alike.
Taxes are the clearest example. The state cannabis excise tax rose from 15% to 19% on July 1, 2025, then dropped back to 15% on October 1, 2025, after Newsom signed AB 564. Even at 15%, Cal NORML calculates that state excise, sales and local taxes can combine to as much as 38%, or 44% on delivery orders.
The most honest voices in this conversation say enforcement and market reform have to move together. Crack down on illegal operators, yes. But also cut the regulatory friction and tax overhead that make legal compliance feel like a competitive disadvantage rather than a baseline.
There are also fair questions about how enforcement gets deployed. Eradication operations, if not carefully managed, can land hardest on small legacy cultivators while larger, better-organized operations adapt and relocate. The prevention, public health and environmental lanes of the program are a reminder that enforcement is only one piece of it.
What is clear from June 25, 2026, is that California has made a significant political and financial commitment. The BSCC and its grantees now have to put that money to work and show measurable results. The industry will be watching every inspection, every shutdown and every cleanup to see whether this investment finally bends the curve.
Frequently asked questions
What is Proposition 64 and how does it fund these grants?
Proposition 64, passed by California voters on November 8, 2016, legalized adult-use cannabis for adults 21 and over and set up a framework for regulating and taxing it. A designated share of state cannabis tax revenue funds the Proposition 64 Public Health and Safety Grant Program, which the Board of State and Community Corrections runs.
The June 25, 2026, announcement of $227 million was the program's fourth cohort and its largest, bringing total program funding to more than $350 million.
Why is California's illicit cannabis market still so large?
Price is the biggest factor. State excise, sales and local taxes can add up to as much as 38% at retail, according to Cal NORML, and licensed products also carry testing, compliance and licensing costs. Unlicensed sellers pay none of that, and Cal NORML estimates they still account for about 6 in 10 sales statewide.
Who receives Prop 64 grant funding?
Local governments. Cities and counties apply to the BSCC for projects in public safety and enforcement, youth prevention and intervention, public health, or environmental impacts. Since the 2025 Budget Act, a jurisdiction must allow retail cannabis sales to qualify, or, for communities under 10,000 residents, allow cannabis delivery.
For this cohort, the BSCC fully funded every eligible applicant by drawing on anticipated Fiscal Year 2026–27 funding.
How does the illicit market affect licensed operators and communities?
Licensed operators face price competition they can't structurally match, which pulls customers away from stores that pay taxes and test their products. That also shrinks the tax revenue that funds programs like this one.
Beyond economics, unpermitted grows have been linked to environmental damage, and communities near large operations deal with public safety concerns. Prior grantees have used this funding to remove unpermitted plants, document environmental violations and seize illegal firearms.
