For visitors
First time at a San Diego dispensary
Bring a government-issued photo identification showing you are 21 or older, and bring cash or a debit card — most licensed retailers cannot process credit cards. Identification is checked at the door before you reach the sales floor. Expect the register total to run well above the shelf price once cannabis taxes are added.
At the door
Every state-licensed retailer checks identification before you enter the sales area, usually in a small reception space. Nobody under 21 may enter for adult-use, including someone simply accompanying a buyer. Have your identification out before you reach the desk; it makes the whole process faster in a queue.
Which identification works
- A California driving licence or state identification card.
- An out-of-state driving licence — normally accepted.
- A passport, including a foreign passport — normally accepted.
- A military identification card. Note that purchasing is a separate question from whether a service member may lawfully use cannabis; see the rules for service members.
Paying
Federal banking restrictions mean most cannabis retailers cannot accept credit cards. In practice you should expect cash, a debit transaction, or an on-site ATM. Some retailers support debit-based systems that add a small transaction fee. Cash is the one method that always works, and it is worth carrying if you are visiting a specific shop for the first time.
Budget for tax, not shelf price
Cannabis in San Diego carries state excise tax, state and local sales tax, and a municipal cannabis tax. The gap between the shelf price and the out-the-door total is substantial. If you are working to a budget, ask a staff member for the out-the-door price before deciding.
How much you can buy
Adults 21 and older may buy up to 28.5 grams of cannabis flower or 8 grams of concentrated cannabis per day. That is a personal limit rather than a per-store limit. Full detail, including how edibles are counted, is on the purchase limits page.
Getting it back to where you are staying
Cannabis must be transported in a sealed container or in the trunk, and consuming it in a vehicle is prohibited whether or not the vehicle is moving. If you are walking, keep it sealed and out of sight — possession is lawful, public consumption is not.
Two things to settle before you buy
First, where you will lawfully consume — see where you can consume, because the list is much shorter than most visitors expect. Second, whether your trip includes a crossing into Mexico — see the border rule, which is absolute.
A note on staff advice
Retail staff can tell you about products, potency, and format. They are not medical professionals and cannot advise on health matters. If you have a health question about cannabis, ask a physician rather than a retailer.
Common questions
- What identification do I need at a San Diego dispensary?
- A valid government-issued photo identification showing you are 21 or older. Out-of-state driving licences and foreign passports are normally accepted for adult-use purchases.
- Do San Diego dispensaries take credit cards?
- Most cannot accept credit cards because of federal banking restrictions. Debit and on-site ATMs are common, and cash is universally accepted. Confirm with the specific retailer before you travel to it.
- Can I bring someone under 21 into the store with me?
- No. Licensed retailers restrict entry to people 21 and older for adult-use, and identification is checked at the door before anyone enters the sales floor.
- How is the price at the register different from the shelf price?
- Cannabis carries state excise and sales tax plus a local cannabis tax, so the total at the register is meaningfully higher than the displayed shelf price. Ask for the out-the-door price if you are budgeting.
- Can I return cannabis I have bought?
- Generally no. Cannabis sales are typically final, though retailers may replace a defective product such as a faulty vape cartridge. Ask about the policy before purchasing.
