The Department of Cannabis Control regulates cannabis packaging and labeling statewide, consolidating rules that used to run through three separate agencies. Every retail cannabis package sold in California has to clear DCC's child-resistant, opacity, tamper-evidence, and labeling requirements before it reaches a dispensary shelf, regardless of whether it is medical or adult-use.
California recognizes three ways to satisfy its child-resistant packaging requirement: packaging certified under the federal Poison Prevention Packaging Act (16 CFR 1700.15 and 1700.20); for single-serving products only, a bottle sealed with a pry-off metal crown or cork-style cap; or, also for single-serving, topical, or inhalable products, plastic packaging at least 4 mils thick that is heat-sealed without an easy-open tab, dimple, corner, or flap. For edibles, orally consumed concentrates, and suppositories, the package has to stay child-resistant for the life of the product, though a multi-serving package is exempt from that requirement if each individual serving is itself packaged to be child-resistant. Inhalable or topical products may use packaging that is only child-resistant until first opened, provided the label carries the statement "This package is not child-resistant after opening." A CR certification is specific to the exact tested configuration: changing wall thickness, resin, or even a color additive without retesting can invalidate it, even when the part looks unchanged. Jadewell builds CR configurations in selected jar and closure formats. Availability is confirmed per format, because certification attaches to the exact configuration that was tested.
Cannabis goods cannot be visible through their packaging. California gives packagers two ways to satisfy this: build opacity into the primary package itself, or ship in a package where the product is visible but require the retailer to place it in an opaque exit bag at the point of sale. For a manufacturer building the primary package, designing in opacity from the start avoids relying on the retailer's exit-bag process to close the compliance gap. Opaque HDPE jars and printed mylar barrier bags both satisfy this at the primary-package level.
Every retail package needs the DCC's universal THC warning symbol, a black triangle printed on a white or light background, at least 0.5 by 0.5 inches, placed clearly on the primary display panel. Labels also need total THC and CBD content per package and per serving, a batch or lot number, the bolded statement "GOVERNMENT WARNING," an ingredient list, allergen warnings, net weight, manufacture date, and the licensee's name and license number. Packaging cannot use bright, kid-oriented colors or cartoon imagery.
Edible cannabis products are capped at 10 milligrams of THC per serving and 100 milligrams of THC per package, regardless of piece count. A package of gummies or a segmented chocolate bar has to divide that 100 milligram ceiling across however many pieces are inside, which sets the practical serving count for the format before flavor or branding decisions even enter the conversation. A separate, narrower exception allows orally dissolving medical products, like sublingual lozenges or strips, up to 500 milligrams per package if each discrete piece holds no more than 10 milligrams and the product is labeled for medical use only.
California's 100-milligram, 10-milligram-per-serving edible cap now matches Washington's and Oregon's current limits, which matters for brands designing a single format to run across all three states.
