California Adult-Use Cannabis Basics for Shoppers
This overview is not a substitute for current state, city or county rules. It identifies the checks a shopper should make before relying on a catalogue or delivery statement.
Age and licensed retail
California allows adult-use purchases for people 21 or older, while medicinal rules differ. Retailers verify age and identity. A store’s current license status should be checked through the official Department of Cannabis Control search.
Local rules and delivery
Cities and counties can apply stricter rules, and a retailer’s service area can be narrower than a city-wide claim. Confirm the exact address and current checkout coverage.
Transport and driving
Do not drive while impaired. California also restricts open containers in vehicles, and cannabis cannot be transported across state lines because it remains illegal under federal law.
What to check before ordering
- Eligible age and valid ID
- Current retailer license verification
