Tijuana Estuary Cannabis Guide: Imperial Beach, California

Imperial Beach sits on a three-mile sand spit between the Tijuana River estuary and San Diego Bay, the last incorporated city before the Mexican border and by some distance the least expensive beach town in the county. That budget-town identity shaped its cannabis politics: while Coronado, Del Mar and Solana Beach wrote flat prohibitions, the City Council here negotiated a development agreement with a retail operator in December 2021 and put the resulting tax revenue toward a general fund that has always run thin.

The result is unusual for South Bay. A shopper in Imperial Beach does not have to drive to National City or downtown San Diego to reach a counter, which is what almost every other small coastal city in the county still requires. State rules apply as everywhere else: 21 and up with a valid ID, 28.5 grams of flower or 8 grams of concentrate per transaction, six plants at home, and a 15% excise line that the Legislature rolled back from 19% on October 1, 2025 under AB 564.

Retail here is concentrated, not scattered. Palm Avenue is the commercial spine of the city, carrying State Route 75 traffic from the 5 freeway west toward the Silver Strand, and the licensed storefront sits on that corridor in a converted auto-sales lot near the 700 block. Everything else in town, from the Seacoast Drive rental blocks to the Oneonta streets on the north side, is residential or small-scale retail with no cannabis zoning, so the Palm Avenue frontage is the single address any operator or landlord in this market cares about.

California got here first and got here messily. Proposition 215 made it the first medical state in 1996, Proposition 64 passed on November 8, 2016 with about 57% of the vote, and licensed adult-use sales opened January 1, 2018. Since July 2021 a single agency, the Department of Cannabis Control, licenses growers, manufacturers, distributors, testing labs, retailers and delivery. The result is the biggest legal market anywhere - on the order of 800 licensed storefronts - sitting on top of a stubborn unlicensed one that still accounts for roughly 60% of what Californians actually consume.

The tax math shifted twice in twelve months. A scheduled increase pushed the state excise tax from 15% to 19% of gross receipts on July 1, 2025. Assembly Bill 564, signed September 22, 2025, reversed it: the rate returned to 15% on October 1, 2025 and is locked there through June 30, 2028, with a review starting in the 2028-29 fiscal year. On top of the excise you pay 7.25% state sales tax plus district add-ons, plus whatever your city charges - 10% in Los Angeles, Oakland and Santa Ana, 4% in Sacramento, nothing at all in San Francisco, which suspended its local cannabis tax.

Access is a map problem, not a legality problem. The Department of Cannabis Control counts roughly 56% of California cities and counties as not allowing retail. Delivery is what fills those holes: state rule 16 CCR 5416(d) lets a licensed retailer deliver into any jurisdiction in California, a Fresno County judge dismissed the 25-jurisdiction challenge to that rule in November 2020, and Senate Bill 1186 separately bars locals from blocking medicinal deliveries.

Two 2026 changes matter at the counter. AB 8 took effect January 1, 2026 and pulled smokable hemp, hemp pre-rolls and synthetic cannabinoids like delta-8 and HHC out of gas stations and vape shops - intoxicating product now belongs to licensed dispensaries. And AB 1775 cafes are finally real: Palm Springs adopted its lounge ordinance in December 2025, San Francisco's took effect August 23, 2026, and Sacramento is phasing in a pilot of up to 40 in-dispensary lounges.

Two brands are impossible to miss in California: STIIIZY, which runs both a vape line and its own dispensaries from downtown Los Angeles outward, and Cookies, whose Melrose store and licensed flower lines helped define the modern menu. Papa & Barkley, based in Eureka, is the reference point for balms and tinctures and runs a dispensary, spa and lounge on Broadway in Humboldt County. Beyond those, buy by farm and category: Sonoma and Humboldt sun-grown flower, solventless hash from small Emerald Triangle processors, and low-dose beverages that have taken over drink coolers since AB 8 cleared hemp seltzers out of grocery stores.

The 2026 story is a market that stopped growing and started consolidating. Licensed retailers rang up $956.7 million in the first quarter of 2026, down from $976.5 million a year earlier, while the Unified Cannabis Enforcement Task Force has destroyed more than 317 tons of illegal cannabis since 2022. AB 8 handed dispensaries the intoxicating-hemp customers who used to shop at vape stores, and AB 1775 lounges are opening a hospitality lane in the cities that opted in. Expect more single-store closures, more delivery-only licenses, and more cities revisiting retail bans as budget gaps widen.
