California cannabis rules: what to know and how to check

In California, adults 21 and older can buy cannabis from state-licensed stores and delivery services. Check the store’s license with the state before you buy. Licensed products must be lab-tested and labeled, and the state issues recalls when something goes wrong.

What’s different in California

California has one state regulator for licensed cannabis, the Department of Cannabis Control (DCC). It licenses businesses, sets testing, label and packaging rules, and runs a public recall portal.

The biggest difference is local. Each city and county decides whether to allow cannabis stores. In DCC's local-ordinance data, 301 of 540 cities and counties (56%) prohibit all cannabis retail. So there may be no licensed store near you. State law says a city or county cannot stop licensed delivery from using public roads, and state rules let licensed delivery go to any city or county in California if it follows the state's delivery rules. Not every retailer delivers everywhere, so check before you order.

Licensed stores that are open to the public must post a DCC QR code certificate in the front window, near the entrance. DCC says you can scan it to check the store's license status. Delivery drivers must carry a copy and show it if you ask.

Since January 1, 2026, state law (AB 8) bans the sale of inhalable hemp products with THC, hemp flower and pre-rolls, products with synthetic cannabinoids, and alcoholic drinks that contain cannabinoids. From 2028, DCC says intoxicating hemp must be made, tested and sold like licensed cannabis.

Licensed does not mean risk-free. Licensed products are tested before sale, and DCC still issues recalls.

What California labs test for

Before licensed cannabis is sold, a state-licensed lab tests a sample of each batch for these eight categories (Cal. Code Regs. tit. 4, § 15714(b)). Passing means the sample met state limits when it was tested. It does not mean a product has no risk. What each test means

  • Cannabinoids
  • Residual solvents and processing chemicals
  • Residual pesticides
  • Microbial impurities
  • Mycotoxins
  • Heavy metals
  • Foreign material
  • Moisture and water activity

Terpenoids are tested only if applicable (§ 15725).

California recalls

DCC posts recalls of licensed cannabis products. CHSA keeps a live list of the latest California recalls, with what to do if you have the product. It updates as DCC posts new notices.

Keep the package. A recall notice lists the product and its batch or UID number, which you match against your label.
