Gov. Gavin Newsom has until September 30 to act on AB 2532, the California cannabis beverage law that passed the Senate 40-0 and the Assembly 74-0 on August 27. If he signs it, every dispensary in the state will have to hand a free measuring device to anyone buying a multi-serving THC drink, starting July 1, 2027.
Unanimous votes usually mean nobody cared about the bill. People cared a great deal about this one. In April, the same bill would have capped every cannabis beverage in California at 10 milligrams of THC per package, and the industry said that would erase most of the category. It got 114 yes votes because its author and the beverage makers rewrote it together.
As introduced by Assembly member Jacqui Irwin, AB 2532 limited a cannabis beverage to 10mg of THC per container. California already caps edibles at 10mg per serving and 100mg per package, and the 100mg bottle is the product the beverage category is built on.
A coalition of operators, trade associations, and supply chain companies put numbers on it in a letter to Assembly Business and Professions Chair Marc Berman:
The coalition did not ask for the bill to be killed. It offered a trade: standardized THC disclosure, uniform warnings, child-resistant packaging, a ban on marketing multi-serving drinks as single-serve, and a consumer education campaign.
Irwin took most of that trade. According to Cal NORML's bill tracker, amendments worked out with the industry removed the 10mg cap, and a May 7 amendment added the measuring-device requirement. The enrolled bill, presented to the governor September 4, does the following beginning July 1, 2027:
Separately, labels on all edibles and beverages must carry the national Poison Help toll-free number.
Because the bill amends Proposition 64, it needed a two-thirds vote in each house. It cleared that easily. The other cannabis bill waiting on the same deadline is AB 1965, on product testing and quality assurance.
The 100mg bottle survives. The label, the clear bottle, the ad copy, and the checkout routine around it all change, and each of those belongs to a different company.
Beverage brands and co-packers need new label art for every multi-serving SKU and, for clear bottles, a way to mark serving lines. On a 12-ounce, 100mg bottle with ten servings, that is a line every 1.2 ounces, which is why the device has to read to a tenth of an ounce. Brands in opaque cans skip the lines but not the label notice.
Dispensaries carry the measuring-device duty. The statute puts it on the retailer at the time of purchase, not on the manufacturer. In practice brands will probably ship cups with cases, because a store that runs out of devices is out of compliance on every multi-serving drink it sells. Either way the store needs a stocking process, a POS prompt, and budtender training before next July.
Marketing teams lose a familiar kind of ad. A 100mg bottle photographed as a poolside single drink is the kind of ad the bill targets, and the advertising rule applies to the brand, the retailer, and any agency working for them.
Packaging, label, and promo vendors have a nine-month sales window with a hard date at the end of it. Some multi-serving brands already ship with a dosing cap or cup. Under AB 2532 the device stops being a brand's choice and becomes a supply item that every licensed retailer in California has to keep on hand.
A veto is possible. But a bill negotiated with the industry and passed without a single no vote is an unlikely candidate, and label redesigns take long enough that waiting for the signature to start planning costs a brand time it may need.
This is a summary of pending legislation, not legal advice. Check the chaptered text and Department of Cannabis Control guidance before changing a label.
The measuring-cup rule is small, but it reaches every store with a beverage cooler. The person who decides whether the store sources its own devices, leans on brands, or drops slow multi-serving SKUs to avoid the hassle is the owner or the purchasing lead, and that decision gets made once. Vendors who want to be part of it need to reach that person this fall, while the compliance plan is still open.
Has Newsom signed AB 2532? Not as of September 21, 2026. The bill was presented to him September 4, and he has until September 30 to sign it, veto it, or let it become law without a signature.
Does AB 2532 cap THC in cannabis beverages? No. The introduced version capped beverages at 10mg of THC per package, but that was removed in amendments. California's existing limits of 10mg per serving and 100mg per package still apply.
When do the measuring-device and label rules start? July 1, 2027, if the bill becomes law.
Who has to provide the measuring device? The retailer, at the time of purchase and at no additional charge, for any cannabis beverage containing more than one serving.
