California buying guide · Limits

How much weed can you buy in California?

Straight answer

28.5 grams of flower and 8 grams of concentrate a day, about an ounce and a quarter ounce, and the THC in edibles and vapes counts toward the 8 grams. That's also the most you can carry. Visitors get the same limit, and medical patients can buy up to 8 ounces of flower a day.

The caps, in plain words

Part of our California dispensary guide, this page covers how much you can walk out with. A store can't sell one adult-use customer more than this in a day, and the numbers match what you can carry.

Flower28.5 g28.5 g

Concentrate8 g8 g

Young plants66

Edibles top out at 10 mg of THC a serving and 100 mg a package. Adult-use topicals and concentrates can reach 1,000 mg a package, and tinctures come in 2 ounce bottles with a measured dropper. Clones sold at stores have to be non-flowering and under 18 inches tall and wide.

Build a bag

Pick resident or visitor, the caps are the same, then tap items into the bag. Edibles and vapes count toward the 8 gram concentrate cap and the store does that math, so the meter shows edibles without one.

What's on you is what counts

The daily cap is written per store, per customer. We haven't found a state rule that adds up buys across stores, so we won't call a second stop legal or illegal. What you carry is capped at 28.5 grams of flower and 8 grams of concentrate either way, and adult-use and medical limits can't be stacked. The store, not you, works out how much concentrate sits in each edible and vape when it rings you up.

Carrying more than that is a misdemeanor with up to 6 months in jail and a $500 fine. If you're 18 to 20, even a small amount is a ticket up to $100. Delivery follows the same daily cap, covered in California weed delivery.

Gifts, home grow and patients

Gifts. Adults can give another adult 21+ up to the same amounts, as long as nothing is paid in return.
Home grow. Six plants per home, not per person, kept locked and out of public view. Cities can ban outdoor grows but not indoor ones.
Patients. Up to 8 ounces of flower and 12 immature plants a day, or more if the doctor's recommendation says so.
Medical-only products. Topicals and concentrates up to 2,000 mg, and lozenges or strips up to 500 mg in 10 mg pieces.
No butane at home. Making concentrates with butane, propane or other volatile solvents at home is banned.
