CA Monthly Puff: California Cannabis Packaging Rules 2027
California cannabis packaging rules 2027 are now on the books, part of a batch of measures from the state’s 2026 legislative session that reshape labels, beverages, and in-store testing. October also brought new pesticide action levels into force, a CEQA challenge to San Diego County’s equity cannabis program, and a tax ruling that cleared a company owner of transferee liability. Here is where California’s cannabis retail market stands this month.

⚖️ CALIFORNIA: NEW PACKAGING, BEVERAGE AND TESTING RULES SIGNED FOR 2027
California’s 2026 legislative session produced a batch of cannabis measures that take effect January 1, 2027, subject to specified later operative dates. Assemblymember Jacqui Irwin’s Assembly Bill 2249, signed August 31, revises packaging and advertising requirements. Beginning January 1, 2028, “attractive to children” will mean packaging designed or likely to appeal to individuals under 21, with the law prohibiting packaging that imitates noncannabis products primarily marketed to children and barring cartoon or overly stylized fruit on edible and vape-cartridge labels, while still permitting realistic fruit that identifies ingredients or production regions. Irwin’s Assembly Bill 2532, signed September 30, requires the national Poison Help telephone number on edible and beverage labels, and beginning July 1, 2027, multi-serving beverage labels must disclose multiple servings, serving volume to the nearest 10th of a fluid ounce, and measurement instructions. That measure retains the 10-milligram THC limit per serving without applying it per container. Assembly Bill 1965, from Assemblymember LaShae Sharp-Collins, requires retail licensees to provide customers with product certificates of analysis on request and to allow the Department of Cannabis Control access to products for off-the-shelf testing.
The session also tightened product rules through Assemblymember Heather Hadwick’s Assembly Bill 2667, which prohibits marketing and selling vapes that imitate non-vape products to conceal their nature from adults and bars interactive video game capabilities. Several other proposals stalled, including Assembly Bill 2697 on locally authorized cannabis drive-throughs, which went to the Senate inactive file, and Assembly Bill 2506 on tribal-state cannabis agreements, which was held in Senate Appropriations. Retailers now have a fixed timeline to bring packaging, beverage labeling, and in-store testing access into line before the 2027 and 2028 operative dates.
⚖️ CALIFORNIA: NEW PESTICIDE ACTION LEVELS TAKE EFFECT OCTOBER 1
On October 1, 2026, California changed its residual pesticide testing regulations for the first time since the program’s original framework was written. The rule retires the old Category I and Category II structure and gives all 66 pesticides on the current panel a numeric action level for both inhalable and non-inhalable products. Twenty-one pesticides moved off zero tolerance, including chlorpyrifos, chlordane, aldicarb and fipronil, which previously failed a batch on any detection above the limit of detection and now carry numeric limits. Nineteen action levels already on the panel were revised, all upward, with the Department of Cannabis Control aligning the numbers to health-based recommendations from the Department of Pesticide Regulation. All residual pesticide results are now reported in µg/g with a pass or fail designation, retiring the old detected or not detected language.
A second phase takes effect on April 1, 2028, expanding the panel to 80 pesticides and tightening many non-inhalable limits considerably. Sixteen of the pesticides that just moved off zero tolerance will face tighter limits again then, several dropping to 0.02 µg/g for non-inhalables. For cannabis retail, the near-term effect is that some batches that would have failed last month under zero tolerance can now pass under a numeric threshold, while the 2028 schedule sets a firmer standard that non-inhalable products will have to meet.

📋 SAN DIEGO COUNTY: CEQA SUIT CHALLENGES SOCIALLY EQUITABLE CANNABIS PROGRAM
On September 23, the County of San Diego and the San Diego County Board of Supervisors were formally served over the County’s adoption of the Socially Equitable Cannabis Program, according to the Valley Roadrunner. A group of county residents known collectively as No Skunk Butts filed a petition for writ of mandate on September 18 in San Diego County Superior Court, and the County and Board were formally served September 23. The group alleges that the County’s environmental review and approval of the program violated the California Environmental Quality Act (CEQA). The Board certified the Final Program Environmental Impact Report and approved key elements of the program by a 3 to 2 vote on August 19, with final adoption completed September 2. The program follows more than five and a half years of development, about $5 million in reported County expenditures, and an environmental review exceeding 2,000 pages.
The challenge targets the County’s environmental findings rather than the equity goals the program was built around. Eddie Lain of No Skunk Butts framed the dispute as a question of whether achieving one important objective requires accepting significant, unavoidable environmental impacts on the communities and environment, which keeps the program’s path forward tied to the outcome of the CEQA case.

📋 CALIFORNIA: SINGLE MEMBER OF CANNABIS COMPANY CLEARED OF TRANSFEREE TAX LIABILITY
A California man who was the single member of a cannabis company is not liable as a transferee for the company’s unpaid tax, despite being paid $200,000 in consultant fees, according to a Law360 Tax Authority report published October 5. The decision addresses whether a payment to an owner of a cannabis business can be treated as a transfer that makes that person personally responsible for the company’s outstanding tax bill. In this instance, the outcome went in the owner’s favor, and the consultant fees did not carry the company’s tax debt over to him.
Transferee liability questions follow cannabis businesses closely because the sector carries heavy state and federal tax exposure, and regulators look to recover unpaid amounts from people connected to a company. A ruling that separates a consultant payment from a company’s tax obligation gives California cannabis owners a clearer line between compensation they receive and liabilities the business owes.
The Bottom Line
October 2026 stacked regulatory change onto California’s cannabis market. The California cannabis packaging rules for 2027 set new label and testing requirements, fresh pesticide action levels took effect October 1, and San Diego County now faces a CEQA suit over its equity program. A tax appeal also separated a $200,000 consultant payment from a company’s unpaid tax.
